Using data from the China Social Survey 2013 and statistics from the Ministry of Environment Protection of China and the Institute of Public & Environment Affairs, this study empirically examines the relationship between actual and perceived air pollution and the moderating effect of environmental transparency on that relationship with a multilevel ordered logistic strategy. Estimations indicate a significant congruence of actual (both particulate matter less than 10 µm in diameter and sulfur dioxide) and perceived air pollution. More importantly, environmental transparency of local government is found to moderate the relationship between actual and perceived air pollution by neutralizing the halo effects and building more alert perceptions when local air quality deteriorates. Our findings not only challenge the work of identifying a mismatch of actual–perceived air pollution in some developed countries but also suggest that, apart from abating actual air pollution, environmental transparency should be emphasized and strengthened in institutional buildings to help address pollution challenges in developing countries.

This article examines the issue of party unity in Hong Kong’s Legislative Council (LegCo). By analysing the LegCo roll-call votes, one can see that the voting patterns of its members are characterised by strong party unity. In particular, a cross-party comparison reveals that for the pro-establishment parties, the Liberal Party had a higher level of unity than the Democratic Alliance for the Betterment and Progress of Hong Kong (DAB); for the pro-democracy parties, the Civic Party had a higher level of cohesion than the Democratic Party. Furthermore, this article shows that strong party unity is likely to be the joint product of party discipline and policy homogeneity among partisan members. Based on the empirical results, the article questions the traditional wisdom that party politics in Hong Kong is necessarily underdeveloped for its simple juxtaposition of party politics with the performance of political parties in elections. Instead, it is suggested that for a better understanding of party politics in Hong Kong, due attention should be paid to the legislative process.
