China Policy Journal tween objective and subjective performance indicators (Miller and Miller 1991). Due to the differences in conceptualization, measurement, and model specification, the debate has continued and research findings are mixed. A stream of studies tries to empirically show that subjective government performance are influenced by individual demographic characteristics such as gender, age, education and race, and individual use experience and expectation (Brown and Coulter 1983; Stipak, 1979, 1980; Swindell and Kelly 2000; Van Ryzin and Immerwahr 2008). Stipak (1979) argued that many public services are rarely used by citizens. The relationship between subjective indicators and objective indicators is confounded by many statistical problems. Brown and Coulter (1983) empirically explored the relationship between residents’ perceived police performance (e.g., policy response time, police treatment of people, and police service quality) and corresponding objective indicators, finding that subjective indicators are not significantly related to objective indicators. However, other scholars disagreed that previous studies have various methodological problems. At least in public service areas such as park maintenance and street cleaning, if outcome-oriented objective indicators and a more scientific research design are adopted, subjective and objective indicators are significantly related, which means that citizen’s perception of government performance can reflect government genuine performance (Andrews et al. 2011). Using New York public school data, Charbonneau and Van Ryzin (2011) found that parents’ subjective assessment of education quality corresponds fairly well with objective school performance measures. Proving public goods and service, and regulating market are two essential functions of government. Air is a pure public good. Without government regulation, due to air pollution’s externality and spillover effects, “the tragedy of commons” takes place (Burger and Gochfeld 1998). Air quality is considered as a sign of government regulatory capacity and an essential indicator of government performance (Holzer and Yang 2004). Different from other public services such as park and library; nobody can escape from enjoying the “service.” Air pollution is highly sensible and visible. However, it does not necessarily mean subjective perceptional measures are reliable in measuring air quality. Perception of air pollution is socially constructed by individuals and societal characteristics, as well as their interactions (Li and Li 2012). Human body is an adaptive system, and long-time exposure to pollution could change the psychological and biological formula for evaluating air quality. Objective measures of air pollution are based on a universal set of scientific measures according to a set of universal scientific “truth” of public health. In contrast, regular people do not have professional equipment and knowledge to detect air quality. In addition to their personal experience, their perception of air quality is highly influenced by information provided by mass media 92
