Corruption threatens the sustainability of political and administrative institutions as well as the enforcement of the rule of law. Previous research has consistently demonstrated that corruption can diminish public support for and trust in the ruling party and government,Footnote 1 and reduce electoral support for individual politicians, particularly in developing countries.Footnote 2 It also jeopardizes the political legitimacy of a regime.Footnote 3 Cognizant of the undesirable consequences of corruption and the global trend for anti-corruption initiatives, the Chinese government has substantively intensified its efforts in investigating official corruption since the 18th National Congress of the Chinese Communist Party (CCP) on 8 November 2012.Footnote 4 According to one corruption control index, the World Bank's Global Governance Indicators project, China's score has improved, from -0.44 in 2012 to 0.05 in 2021, indicating that the country's anti-corruption efforts have made progress.Footnote 5 From 2012 to June 2021, 3.85 million corruption cases were opened, 4.089 million people were investigated or dealt with, and 3.742 million people were subject to Party disciplinary and governmental sanctions.Footnote 6
How do anti-corruption efforts influence public attitudes towards corruption and the government? Existing research focusing on political trust or public support for central government suggests that anti-corruption policies and efforts can yield both positive and negative feedback effects within the political system.Footnote 7 Anti-corruption efforts have been found to increase political trust in state government in the USFootnote 8 and trust in central government in China,Footnote 9 reduce public perceptions of corruption,Footnote 10 and strengthen public support for political leadership at the central government level.Footnote 11 Yuhua Wang and Bruce Dickson, however, find that anti-corruption campaigns have reduced public support for the central government and the CCP by altering the public's beliefs about public officials.Footnote 12 Jiangnan Zhu, Huang Huang and Dong Zhang find that anti-corruption efforts in the field of real estate increases public trust in central government but not in provincial governments.Footnote 13 Moreover, the effectiveness of anti-corruption policies can be undermined or interfered with by trust deficits.Footnote 14 Anti-corruption efforts and policies may also have other unforeseen consequences, such as marginalizing the role of legal institutions.Footnote 15
Mixed research findings can be attributed to the interpretive effects of anti-corruption efforts and policies. Policy scholars using policy feedback theory have proposed that public policies can influence political attitudes through two mechanisms: resource effects and interpretive effects. Resource effects occur when policy provides material and incentive benefits, while interpretive effects occur when the policy implementation shapes individuals’ normative views and their cognitive perceptions of policies, themselves and others.Footnote 16 Interpretive effects may also occur through informational framing and communication.Footnote 17 Information disclosure may enhance the public's evaluation of the government, but it can also expose flawed policies to the general public and generate criticism,Footnote 18 especially through informal information sources.Footnote 19 Previous research on anti-corruption efforts has also suggested that the subjective perceptions of both corruption and anti-corruption measures can influence public attitudes.Footnote 20 In summary, while intensified government anti-corruption efforts may increase the political salience of the fight against corruption, individuals may perceive the same “fact” of anti-corruption efforts in different ways, leading to varied public attitudes towards the government.
This research aims to make the following contributions on four aspects. First, public opinion and policy researchers have long debated whether political attitudes are built on policy outcomes and performanceFootnote 21 or unthinking emotional response.Footnote 22 Previous research, whether using survey experimentsFootnote 23 or short-term panel surveys,Footnote 24 suggests that anti-corruption policies may trigger negative emotional responses and thereby jeopardize support for the regime and trust in central government. However, long-standing existing policies can affect macropolitical attention,Footnote 25 which can generate issue publics who are more knowledgeable about public issues and policies and more likely to rationalize their evaluations based on policy performance. By examining the relatively long-term effect of objectively measured anti-corruption efforts, spanning from 2010 to 2018, we can contribute to this debate by answering whether long-term and ongoing anti-corruption efforts might produce different effects on the public's evaluation of local government by influencing the public's opinion of policy outputs, i.e. the perceived level of existing corruption in our case. Moreover, by focusing on the public's evaluation of local government, we address a gap in the research, as most studies concentrate on central-level political trust.Footnote 26 Local-level evaluations may show different patterns and have distinct causes compared to attitudes towards the central government. Yet changes in the public's evaluation of local government can impact broader political trust and regime support.Footnote 27
Second, our research is among the first to apply policy feedback theory to hypothesize why anti-corruption efforts can generate positive resource effects and subsequently transform these effects into interpretive outcomes by influencing perceptions of policy performance and outputs. While we consider that the interpretive effects of anti-corruption efforts can occur through the communication of anti-corruption information,Footnote 28 our research extends beyond merely examining the effect of information on public attitudes.
Third, we expand the policy areas examined in previous policy feedback research to include anti-corruption policies. Existing research on policy feedback effects mainly focuses on social policiesFootnote 29 or regulatory policies that are highly tangible and visible for both target groups and the general public.Footnote 30 However, anti-corruption policies may have both resource and interpretive effects on the general public as a whole, rather than targeting a specific beneficial group. More importantly, while existing policy feedback research has conceptualized interpretive effects in terms of political efficacy, trust, policy support and understanding of target groups,Footnote 31 our focus on the mediating role of public perception of existing corruption offers an alternative pathway for understanding the interpretive effects of anti-corruption efforts – namely, through perceived policy performance and outputs.
Finally, our additional analysis examines how anti-corruption efforts affect the public's perception of and evaluation of local government across different time periods and groups with varying levels of trust and perceptions of pre-existing corruption. This analysis not only strengthens and complements our basic models but also contributes to the growing body of scholarship on conditional policy feedback models by providing new insights into the moderating roles of time and pre-existing perceptions at both aggregate and individual levels.Footnote 32
Theoretical Analysis and Hypotheses
Public perception of corruption
The public's perception of corruption derives from individuals’ subjective evaluation of the level and degree of existing corruption, based on the corrupt behaviour of governments.Footnote 33 It is shaped by the process of coming into contact with, acquiring, accepting and learning from corruption-related information.Footnote 34 It is also influenced by personal experience of corruption,Footnote 35 the state of economic and social development,Footnote 36 and demographic factors.Footnote 37 When the general public is aware that corruption is widespread in a country, public perception of existing corruption tends to be high. Consequently, the general public may hold a belief that the government and the whole political system are unreliableFootnote 38 and incompetent,Footnote 39 and thus will be reluctant to participate in public issues.Footnote 40
Some studies focus on the effects of the perception of corruption and find that an increased perception of corruption can negatively impact political trust by lowering the public's evaluation of government performance, although such effects may vary according to the level of government.Footnote 41 A heightened perception of existing corruption can also negatively influence public attitudes regarding anti-corruption effortsFootnote 42 and regime support.Footnote 43 Building on this research, this paper focuses on whether anti-corruption efforts, by influencing the public perception of corruption, can affect the public's evaluation of local government performance.
Anti-corruption policies, public perception of corruption and public evaluation of local government performance
Public policy can be influenced by the political system and, in turn, can influence politics. Since Elmer Eric Schattschneider first proposed that existing policies can shape politics and policymaking, much literature has found that existing policies can affect public attitudes and behaviour through two mechanisms: resource effect, in which policies stimulate public support for specific policies by increasing the resources and material benefits for the beneficiaries, and interpretive effect (or cognitive effect), whereby policies can influence political attitudes and behaviour by influencing the cognitive process of social actors and shaping the public's views of society and government.Footnote 44
Anti-corruption policies, as regulatory policies, can also influence public opinion through the two pathways mentioned above. First, anti-corruption actions can affect the public's interests and capacities and thus create a positive resource effect. On a macro or societal level, anti-corruption measures can safeguard public interests by addressing the inequitable distribution of social resources and promoting the effective and efficient allocation of resources,Footnote 45 which may help to establish a positive policy image, lower the public perception of existing corruption levels and improve the public's evaluation of government. On a micro level, personal experiences with corruption can lower the public perception of existing corruption and enhance the public's evaluation of government performance.Footnote 46 Anti-corruption efforts can also strengthen the self-discipline of, and institutional restraints on, government officials,Footnote 47 thereby reducing people's chances of encountering government corruption and thus fostering a more positive perception and evaluation of government.
Second, positive resource effects can shape public opinion by influencing cognitions of governments, policies and individuals,Footnote 48 leading to positive interpretive effects when policies enhance the perceived value and significance of individuals’ own citizenship.Footnote 49 Therefore, the resource effects of anti-corruption efforts can shift the meaning of citizenship by signalling that the government prioritizes the public's interests over those of public officials. Relatedly, signalling theory suggests that government disclosures can turn invisible capabilities into observable signals for the public.Footnote 50 By disclosing more anti-corruption cases, the government communicates its intentionFootnote 51 to address corruption and provides information about the quality of its efforts,Footnote 52 leading to a more positive perception of policy outputs – namely, a perceived lower level of existing corruption.
Moreover, interpretive effects can also arise from informational communication, whether through news media or interpersonal interactions.Footnote 53 Typically, the public has limited access to information about government officials’ corruption levels. Disclosures of anti-corruption cases, often via social media, can make this information more visible.Footnote 54 However, divergent informational sources, types of information and framing of anti-corruption efforts can have mixed effects on public attitudes towards existing corruption and political trustFootnote 55 and change public expectations in unforeseen ways.Footnote 56 Economic growth in China has increased public awareness of rightsFootnote 57 and critical thinking.Footnote 58 This rise in critical citizenship may reduce trust in local governments,Footnote 59 potentially leading to negative feedback from anti-corruption disclosures.
However, we expect a positive impact from anti-corruption information disclosure in China for three reasons. First, negative feedback effects in mass politics often arise when citizens are more sensitive to policy losses than to gains,Footnote 60 or when policies are framed as loss-imposing by opponents.Footnote 61 However, in China, the combination of the one-party system, elite cohesion and political control over news limits the diversity of political information and restricts public access to such frames.Footnote 62 When the Chinese government releases anti-corruption information, it uses selective disclosure and standard language to minimize negative effects.Footnote 63 While journalists are permitted to report on corruption cases, they must avoid commenting on politically sensitive and legal cases.Footnote 64
Second, another factor that may influence the general public's interpretation of anti-corruption information is the informational source. Jiangnan Zhu, Jie Lu and Tianjian Shi find that formal media can reduce perceptions of corruption, whereas grapevine information can increase them.Footnote 65 However, we argue that the effect of grapevine information can be limited in China owing to the restricted access to unofficial media sources. People seek divergent informational sources only when they feel free to do so.Footnote 66 Chinese citizens face barriers and both economic and political costs to accessing alternative information, which reduces their motivation – in comparison to citizens in democracies – to seek divergent views.Footnote 67 Furthermore, the Chinese public tends to rely on official media to understand the government's stance on political events.Footnote 68
Third, members of the public are more likely to evaluate policy performance and output when they have sufficient information to link their interests to political outcomes,Footnote 69 rather than relying on unthinking emotional responses.Footnote 70 Our research observes a relatively long-term effect of anti-corruption efforts spanning from 2010 to 2018. While a negative emotional response to rampant corruption cases may initially prevail, continuous efforts and disclosure of related information may enhance political awareness and stimulate conscious deliberation. This process can create a more informed and attentive public that links political values and empowerment with anti-corruption efforts, leading to lower perceived corruption and higher evaluations of local governments.
In summary, we propose the following hypothesis:
Anti-corruption efforts will increase the public's positive evaluation of local government performance by decreasing perception of existing corruption.
Research Design
Data sources
We used multiple data sources including the China Statistical Yearbook (CSY), Chinese Procuratorial Yearbook (CPY) and China Family Panel Studies (CFPS). The CFPS is a biennial, nationally representative survey of Chinese communities, families and individuals, initiated in 2010 by Peking University and the University of Michigan. It covers 25 provincial-level administrative units,Footnote 71 representing about 95 per cent of China's population. The CFPS provides detailed geographical data that allow precise matching of individuals’ evaluations of local government and perceived corruption with provincial-level anti-corruption datasets. Additionally, this repeated cross-sectional design offers researchers many benefits, such as maintaining a stable sample sizeFootnote 72 and examining dynamic effects, while avoiding attrition and response bias issues. Longitudinal data also enable us to mitigate endogeneity issues through methods like identifying a quasi-experiment and employing strategies such as lagged dependent variables, split-sample analysis pre- and post-treatment, and difference-in-differences (DID) analysis.
In our study, the dependent variables and key explanatory variables were obtained from the CFPS, 2010–2018. The CFPS contains three categories of questionnaires: village (residence), household and individual questionnaires. We obtained the per capita household income from the household questionnaire, while individual-level variables, such as public evaluation of local government, perception of corruption and demographic factors, come from the individual-level questionnaire. Chinese translations of the selected CFPS survey items appear in Appendix Table A1.
Macro-level variables were obtained from the CSY and CPY in corresponding years from 2010 to 2018. In 1995, China established the General Bureau of Anti-Graft and Bribery, which became the main anti-corruption agency. In 2018, this bureau was merged with the newly created National Supervisory Commission, and since then, prefecture-level procuratorates have stopped releasing corruption data. Given that the earliest available CFPS data are from 2010, we matched data on provincial-level corruption and bribery cases with the CFPS data in 2010, 2012, 2014, 2016 and 2018 in corresponding provinces. To ensure the consistency of the sample, the observations that have missing values in any of the five national surveys were excluded. As a result, our dataset consists of 15,844 valid observations.
Variables
Measurements
More details of our measurements can be found in Appendix Table A2.
(1) Local government evaluation
We measured the public's evaluation of local government using a CFPS survey question asking respondents to rate the municipal or county government's work (from 1=worse than before to 5=a considerable number of good results).
(2) Anti-corruption actions
Two main approaches to measuring anti-corruption actions have been used in previous research: (1) subjective perception of anti-corruption efforts, as measured according to Transparency International's Corruption Perception Index; the World Bank's Corruption Control Index; the Bribe Payer Index; and the Business Environment and Enterprise Performance Survey. However, these subjective measures can be skewed by experts’ cultural backgrounds and ideologies.Footnote 73 Therefore, other studies have adopted (2) objective measurements, which include data on corruption cases, researcher-constructed case databases and case-tracking survey data.
This research chose an objective measurement of anti-corruption efforts for three reasons. First, following previous research,Footnote 74 this straightforward measure is intuitive and makes a clear impression without imposing much cognitive load.Footnote 75 Second, the Chinese government cites the number of anti-corruption cases to highlight its success and gain political support, making this data a key indicator.Footnote 76 Owing to the high degree of control China exerts over media releases regarding anti-corruption information, Chinese citizens are less active in selectively seeking information from diverse media sources,Footnote 77 making government-released data the most accessible information to the public. Third, as Siqin Kang and Jiangnan Zhu note, many of the officials arrested are implicated by their past behaviour. Therefore, the number of investigations and arrests may better reflect anti-corruption efforts rather than the level of corruption.Footnote 78
We calculated the ratio between the number of government officials prosecuted by the procuratorate and the total number of government officials in each province. The number of government officials prosecuted was obtained from the CPY.Footnote 79 The number of government officials in each province was the number of personnel in national institutions, which was obtained from the CSY. Notably, the ratio of government officials prosecuted to the total number of government officials was extremely small (typically <0.005). Following the approach taken by Sheng Xin, Songlin Guo and Xiaochen Chang, we multiplied this ratio by 100 to make the interpretation of the impact of anti-corruption efforts on public evaluation more straightforward and clear.Footnote 80
(3) Perception of corruption level
The question, “How severe do you think the problem of government corruption is in our country?” (from 0–10), was selected to measure the public's perception of government corruption.
(4) Control variables
Taking into account that the public's evaluation of local government performance may be affected by various variables, we controlled for age, gender, education level, marriage status, employment, type of residence, religious belief, CCP membership, internet use and household income.Footnote 81 We also controlled for provincial-level gross domestic product (GDP) per capita.
Descriptive statistics
Figures 1–3 present the spatiotemporal evolution of anti-corruption efforts, local government evaluation and the perception of corruption levels in each province over the years. Figure 1 shows that provinces such as Chongqing, Fujian, Anhui, Guangxi, Heilongjiang and Liaoning maintained higher levels of anti-corruption efforts over time, while Hunan, Gansu, Zhejiang and Beijing exerted lower levels. Figure 2 reveals that among the provinces with higher levels of anti-corruption efforts, Chongqing consistently received higher scores in local government evaluations, whereas Beijing scored lower in provinces with lower levels of anti-corruption efforts. Notably, Zhejiang stands out, with local government evaluations above 50 per cent, while local government evaluations in other provinces vary across the years. Figure 3 shows that in provinces with high levels of anti-corruption efforts, public perceptions of corruption in Chongqing and Guangxi remained below 50 per cent, while Heilongjiang and Liaoning had perceptions above 50 per cent. Among the provinces with lower anti-corruption efforts, the perceived corruption level in Beijing is always above 50 per cent, while the public perceptions of corruption in other provinces vary across the years. The descriptive statistics, temporal trends of the three key variables and their detailed discussions appear in the online Appendix, Section I 1–3 and 1–4.

Model specification
Panel regressions were used to test the relationship between anti-corruption efforts, public perceptions of corruption and local government evaluations. Two-year lagged explanatory variables were used to address the endogeneity problem, gain better control over the persistence of anti-corruption efforts and capture the long-term feedback effects of anti-corruption policies over time.Footnote 82 More details are provided in the online Appendix, Section I 1–5.
This research conducted multiple robustness tests to check whether the relationship between anti-corruption efforts and local government evaluations withstands further analyses. Additional analyses examined whether the effects of anti-corruption efforts vary across different groups and time periods.
Results
Panel regression analysis
This study first used a stepwise ordinary least squares (OLS) panel regression to analyse the impacts of anti-corruption efforts on evaluations of local government. As shown in column (1) in Table 1, anti-corruption efforts can increase the public's evaluation of local government at the 1 per cent significance level. After incorporating control variables in column (2) in Table 1, the results are in line with our hypothesis, when all other variables are held constant: the public's evaluation of local government increased by 1.038 units for each 1 per cent increase in anti-corruption efforts.

Notes: Standard error in parentheses; *p<0.1**p<0.05***p<0.01. The sample size for column (2) was reduced to 51,038 because of missing values for control variables.
The empirical results also show that, when other variables are held constant, the public evaluation of local government performance increased by 0.478 units for each percentage point increase in GDP per capita. Additionally, individuals who were married and used the internet rated local government performance 0.061 and 0.055 units lower compared to others, respectively.
Robustness checks
We used several methods – controlling for omitted variables, using alternative measurements and models, and applying DID strategies – to validate the results in Table 1. The results are consistent with our main findings. More details are given in the online Appendix, Section II.
Mediating effect of public perceptions of corruption
Figure 4 shows how anti-corruption efforts impact public evaluations of local government performance by influencing the perception of existing corruption (see full results in the online Appendix, Table A5). When all other variables are held constant, evaluations of local government decreased by 0.031 for each 1 per cent increase in the perceived level of existing corruption. The evaluation of the local government increased by 1.002 and the perception of existing corruption decreased by 3.777 units for each 1 per cent increase of anti-corruption efforts.

Figure 4. Mediating Effect of Perception of Corruption Level
Notes: Because there is no corruption perception data in the CFPS database for 2010, we excluded all samples in 2010 from the re-regression analysis. The conclusion remained largely unchanged. See Appendix Section IV for further details.
The indirect effects of anti-corruption efforts on the evaluation of local government through public perceptions of corruption are small (0.117 = 3.777×0.031). However, theoretically, our finding highlights how policies can shape public attitudes through perceptions of policy performance. Empirically, the Sobel test reveals a Z statistic of 4.287 (p<0.001) and shows that the mediating effect of public perception accounts for 26.43 per cent of the total effect.Footnote 83 This further validates our hypotheses and indicates a significant reduction in the impact of anti-corruption efforts on evaluations of local government when perceptions of corruption are factored in.
We further include two sets of factors that may influence perceptions of existing corruption as control variables: media environment factors – the internet penetration rate, optical cable construction level and proportion of internet users – as well as existing citizen grievances, measured by two-year lagged local government evaluations.Footnote 84 We did not see any substantive changes in the relationship between anti-corruption efforts and public perception of corruption (see Appendix Table A6).
Additional analyses
In recent years, policy and public opinion scholars have begun to build conditional policy feedback models considering the personal, institutional and contextual factors that can moderate the relationships between policies and political attitudes.Footnote 85 Therefore, we test whether the effects of anti-corruption actions on public perception and evaluations vary across multiple groups and time periods.
Subsamples with high versus low trust
Trust not only has a direct effect on political attitudesFootnote 86 but also interacts with these attitudes in evaluating the effectiveness of public policies and government.Footnote 87 This section examines the moderating effect of trust on the relationship between anti-corruption efforts and public perceptions of corruption.
Trust can be categorized into interpersonal trust and political trust, with ongoing debates about their relationship. Some argue that interpersonal trust fosters political trust,Footnote 88 while others believe it does not directly translate.Footnote 89 Political trust can be operationalized as trust in the political system, political parties and public officials.Footnote 90 In China, the term “cadres” refers to those who are working for the state in the CCP, public organizations and the military, so “trust in cadre” measures trust in public officials.
We categorized survey respondents into two different subsamples, based on their levels of interpersonal trust (Itrust) and political trust (Ptrust), respectively.Footnote 91 We adopted two measures for both Itrust and Ptrust. The first measure of Itrust came from a CFPS survey question asking if respondents believe that most people can be trusted (Itrust=1) or if they feel the need to be cautious (Itrust=0). The first measure of Ptrust was based on the “trust in cadre” question (0=distrust to 10=highly trust), which was then categorized into low (0–5) and high (6–10) political trust.Footnote 92 For the second measurement, we used principal component analysis (PCA) to create an interpersonal trust index from two questions: “trust in neighbour” and “trust in stranger” (0=highly distrust to 10=highly trust), and a political trust index from four questions about personal experiences with public officials (for example, conflicts, unfair treatment, unreasonable delay, charges). Respondents were divided into two groups based on whether their trust index was above or below the mean.
The results presented in the online Appendix, Table A11, show the impact of anti-corruption efforts on public perceptions of corruption across different levels of trust. Regardless of the level of interpersonal trust, anti-corruption efforts significantly reduced public perceptions of corruption. Moreover, when individuals have lower trust in cadres, anti-corruption efforts do not significantly influence the perception of corruption, but when trust is higher, the negative effects of anti-corruption efforts on the perceived level of corruption persist.
Subsamples with high and low pre-existing provincial- and individual-level perceptions of corruption
Since perceptions of existing corruption vary across provinces, reflecting regional differences in political and social conditions, we conducted a split sample analysis to examine how anti-corruption efforts influence evaluations of local government depending on pre-existing provincial and individual perceptions of corruption, respectively. We divided our respondents into two groups based on two criteria: one group was selected according to whether the 2012 level of perceived corruption in the respondents’ province was above or below the mean, and the other group was selected based on individual-level perceived corruption in 2012. The year 2012 was chosen because it is a key turning point in China's anti-corruption policies and the earliest year available for measuring corruption perceptions.Footnote 93
We found that individual-level perceptions did not significantly change the impact of anti-corruption efforts. However, in regions with higher average perceptions of corruption, anti-corruption efforts more effectively improved the evaluations of local government compared to regions with lower average perceptions of corruption (see Appendix V 5-2).
Dynamic effects of anti-corruption efforts
We are curious about whether time plays a role here (see online Appendix, Section V 5-3). Because 2012 was a pivotal year in China's anti-corruption efforts, marked by the 18th National Congress and the beginning of Xi Jinping's 习近平 leadership,Footnote 94 we split our samples into two time periods – years before and after 2012 – to conduct split sample analyses (see online Appendix, Table A14). After 2012, by examining different time periods – 2012 to 2014, 2012 to 2018, and extending to 2020Footnote 95 – we found that anti-corruption efforts can increase the public's evaluation of local government and lower the perceived level of existing corruption.
However, the effect size was greater in all periods after 2012 compared to before 2012, when the positive effect was not statistically significant. Therefore, while this result reinforces that continuing and long-term anti-corruption efforts can bring positive outcomes, the 18th National Congress in 2012 played a crucial role in amplifying such positive effects.
Discussions and Conclusions
This study examines the effects of anti-corruption efforts on public evaluation of local government performance using a panel survey spanning the years from 2010 to 2018. Relying on policy feedback research, we introduced the public perception of existing corruption as a mediator and find that anti-corruption efforts positively influence evaluations of local government performance by reducing the perceived corruption level. However, the impact of anti-corruption efforts on the public perception of corruption varies with the level of political trust, the provincial-level pre-existing public perceptions of corruption and the point in time, i.e. before or after 2012, underscoring the complexities of maintaining political legitimacy through anti-corruption policies under different conditions.Footnote 96
Long-standing anti-corruption efforts can lower the public perception of existing corruption and improve local government evaluation
Our results showing the positive impact of anti-corruption efforts on local government evaluations seem to be inconsistent with previous findings that anti-corruption campaigns have a negative impact on regime support.Footnote 97 We suggest these differences could result from the length of the data collection period, different focuses of independent variables – corruption information versus anti-corruption effort – and the different levels of government – local versus central governments.
First, our research goes beyond previous research that solely focuses on anti-corruption information and associated short-term effects on public perceptions.Footnote 98 In survey experiments focusing on information, the impact of information on public attitudes often diminishes over time,Footnote 99 and the external validity of survey experiments typically faces many challenges such as the difference between experimental samples and the target population, variations in experimental and target treatments, and limited generalizability across contexts.Footnote 100 Our study addresses these challenges by combining objective measurements of anti-corruption efforts with national panel surveys and by controlling for anti-corruption information-related variables. More importantly, by examining a relatively long-term effect of objectively measured anti-corruption efforts from 2010 to 2018, our research implies that long-standing existing anti-corruption policies may increase political awareness and public knowledge.Footnote 101 For example, while Wang and Dickson analysed two surveys that were conducted before and during the anti-corruption campaign, our research covers the three years before and six years after the campaign.Footnote 102 Our results suggest that while short-term attitudes may be driven by impulsive emotional reactions, ongoing efforts may provide Chinese citizens with sufficient information about anti-corruption policies to rationalize their evaluations based on perceived policy performance and outputs, leading to a higher evaluation of government.
Second, while different types of anti-corruption media information and sources can generate different public reactions, policy feedback is much more than the reception and interpretation of information. Given the strict censorship and media control in China, the public is unlikely to be exposed to conflicting information about corruption that could trigger an “awakening of knowledge” and lead to the questioning of government officials’ integrity and a subsequent decline in government evaluations.Footnote 103
More importantly, this research introduces public perception of existing corruption as a mediator to test how the positive resource effects of anti-corruption efforts transform into a positive interpretation. After controlling for media environment, our results indicate that positive-interpretation feedback persists. Our findings suggest that the public does respond to policy performance and outcomes.Footnote 104 The number of corruption cases may serve as an indicator for the public of both the quality of anti-corruption efforts and the intention of resolute action.Footnote 105
Third, another possibility for our differing findings is that, in China, individuals may either attribute the achievements of anti-corruption efforts more to local government rather than to the central government or, conversely, place blame for corruption on the central government rather than local governments. The 18th National Congress intensified the anti-corruption campaign by targeting it at both high-level officials (“tigers”) and lower-ranking officials (“flies”). The focus on high-level officials may have diverted public attention away from corruption among grassroots officials. Wang and Dickson also found that the negative effect of anti-corruption campaigns on support for local parties and governments is less significant when compared to the negative effect it has on support for central government. Although the unique pattern of the hierarchical trust model where people trust central government more than they trust local government still dominates in China, there are cases where local governments might gain trust, especially if the local government quietly protects people from an ill-conceived central policy.Footnote 106
However, our research focuses on evaluations of local government performance and does not directly address the effects of anti-corruption efforts on public support for the central government. Previous studies have suggested that trust in the central government reflects public confidence in the centre's commitment, while trust in local governments reflects confidence in the centre's capacity to implement policies.Footnote 107 Therefore, it remains unclear whether our findings can also imply a positive long-term effect of anti-corruption efforts on public attitudes towards the central government, or if they reveal contrasting effects on attitudes towards the central versus local governments.
The effect of anti-corruption efforts on the public's perception of corruption and evaluations of local government varies according to political trust and provincial-level perceptions of corruption, not by time periods after 2012
First, our additional analyses imply a conditional feedback effect of anti-corruption efforts on public perceptions of corruption and public evaluations, contingent upon individuals’ subjective trust in public officials and their direct experiences with public officials. When people trust public officials and have positive experiences with them, they tend to view anti-corruption efforts more favourably as the number of filed and investigated corruption cases increases. Otherwise, the positive policy imagery may be tarnished. The result may also explain why, despite strong anti-corruption efforts, Heilongjiang, Jilin and Liaoning provinces in north-east China experienced high levels of perceived corruption and lower local government evaluations. In addition to the lower economic development status, the persistent inefficiency of local governments in north-east China and their failure to transition to a service-oriented model may have resulted in lower trust in local officials, compared to other provinces, as shown in our data. Another survey also suggests that provinces in north-east China are perceived as being less efficient than coastal provinces, with 68.7 per cent of respondents citing low-efficiency government, 32.0 per cent pointing to corruption, and 21.5 per cent highlighting restrictive government policies and weak market vitality.Footnote 108
Second, we find that in regions with higher average perceptions of corruption, anti-corruption efforts more effectively improve evaluations of local government. This finding does not contradict the well-established notion of confirmation bias that individuals tend to reinforce their existing beliefs.Footnote 109 Rather, there are significant differences between individuals’ prior perceptions of corruption and the provincial-level perceptions of corruption in their area. Provincial-level perceptions of corruption reflect broader cultural and political conditions, which can, in turn, influence policy awareness and political attitudes.Footnote 110 Moreover, previous policy feedback research suggests that policy interventions can be especially impactful for regions or groups that are more affected by a specific public issue.Footnote 111 As a result, higher perceived corruption in a province may make the issue of corruption more salient in these areas, leading residents to be more responsive to policy changes.
Third, we further extended our research to examine the impact of anti-corruption efforts on public perception of existing corruption and evaluations of local government over four, six and eight years (using biennial data) following the 18th National Congress in 2012.Footnote 112 All models indicate that anti-corruption efforts have positively influenced mass politics, with this effect becoming more pronounced after 2012. This reinforces our suggestion that continuing long-term anti-corruption efforts can bring positive outcomes to mass politics. However, probably owing to its highly centralized political system and policy process, the central government plays a crucial role in amplifying and enhancing the impact of anti-corruption efforts on improving the public's evaluations of government.
Practical implications
Our research has three practical implications. First, despite the ongoing debate regarding the impact of anti-corruption efforts on the public's evaluation of government,Footnote 113 we suggest that practitioners aiming to improve the public's opinion of government should be aware that continually strengthening anti-corruption efforts and creating a long-term institutionalized policy environment for combating corruption are crucial, especially in provinces where the pre-existing perception of corruption is high.
Second, our findings regarding the mediating role of the public perception of corruption on the relationship between anti-corruption efforts and public evaluation of local government suggests that the government should be aware that how to lower the general public's perceived corruption level is important for maintaining the positive effects of anti-corruption efforts on public evaluations. To achieve this, government should consider better mass communication measures and publish more information showcasing daily anti-corruption efforts to inform individuals about the goals and nature of government.Footnote 114 Continually improving and expanding procedures and channels for public participation in anti-corruption policies and efforts may effectively reduce the public perception of corruption and thereby improve the public's evaluation of the government. However, the small indirect effect suggests that the practitioners should also be aware that the interpretation of anti-corruption efforts can be influenced by other factors such as the diversity of information and individual differences.
Third, maintaining a high level of public trust in public officials is crucial for governments aiming to implement anti-corruption efforts without hurting the public evaluation of governmental performance. In particular, the public trust in and positive experiences with local-level administrators and public service providers can magnify the positive outcomes from anti-corruption efforts, resulting in decreased perception of corruption and improved evaluations of local government. Therefore, it is essential to nurture the public service motivations of local officials, particularly those who have greater opportunities for direct interaction with the public.
Limitations
Our research has three limitations. This first is the mismatch between using provincial-level anti-corruption efforts as the independent variable and trust in local government as the dependent variable. However, owing to the Restrictive Data Instruction from CFPS, we can only match respondents to their provincial anti-corruption data, as detailed information below the provincial level is unavailable.Footnote 115 Moreover, previous research indicates that patterns of political trust are similar across subnational levels of government, including provincial, city, county and township governments.Footnote 116
Second, the effects of anti-corruption measures on evaluations of local government can be complex.Footnote 117 This study reveals how anti-corruption efforts influence public perceptions and evaluations, but it does not examine how changes in public evaluations of local governments might, in turn, affect subsequent anti-corruption policies. Future research could expand our research to answer whether anti-corruption efforts in China exhibit self-reinforcing or self-undermining dynamics by influencing public attitudes.
Third, since corruption is often hidden, its true extent is not fully represented by exposed cases.Footnote 118 Moreover, China's centralized political system and the state's tight control of the media can result in incomplete and biased information.Footnote 119 Future research needs more scientific indicators of corruption, such as objective data from increasingly accessible judicial documents.
