China Policy Journal tion in urban China, central and local governments have been endeavoring in spending more resources in environmental regulations. Despite the government proclaims that air quality has been steadily improving, citizens do not resonate and buy, generating an enlarging gap between government rhetoric and citizen perceptions. Given the lingering air pollution, citizens may be hopeless of and habituate themselves to air pollution (Menz 2011), because it has been an essential part of their lives (Johnson et al. 2017). How to mitigate citizens’ discontent with air pollution? Our findings suggest that government should be more transparent in disclosing information and engaging the public, which helps to retain social legitimacy and support. Information-based policy instrument is among lots of policy instruments available to policy-makers, and incentive-based and mandatory instruments are equivalently and even more powerful in improving environmental performance. Despite information-based instrument is not the most powerful policy instrument, it is a promising and cost-efficient one. Lots of recent developments in environmental governance use information disclosure and transparency to nudge residents and industrial enterprises to reduce environmental pollution. It is thus important to highlight the value of information-based policy instruments in improving air quality, both objectively and subjectively. Environmental transparency may be undermined by giant industrial enterprises due to interest entrenchment (Lorentzen, Landry, and Yasuda 2014), and government should leverage the power of social accountability and citizen participation. The ubiquitous data manipulation must be addressed by introducing third-party engagement, since it is common to find interrupted points or discontinuities of air quality monitoring, especially when air pollution is heavy. It is also relevant to expand the comprehensiveness of coverage and the density of monitoring stations, particularly in rural areas, which help citizens more precisely perceive and respond to air pollution. The limitations of the study are threefold, and we hope future studies can replicate and extend our findings. First, the measurements of our key variables could be improved in future research. The measurement of subjective air quality is based on a single item from a national citizen survey, and we will address the issue in our future study. Although air quality is highly sensible and easier to be detected and felt, a subjective AQI consisting of multiple questions would be better. Citizens’ perceptions and satisfaction are conceptually different, and we cannot distinguish their fine-grained differences due to data limitations. Our measurement of objective air quality could also be improved by using more recent data, since the Chinese government revised the national Ambient Air Quality Standards and included the concentration level of PM 2.5 in 2013. It should be noted that information disclosure is different from information availability or access, and we use 104
