| Summary: | This study is to investigate whether the multifaceted roles of democracy have a positive relationship with environmental quality. Using a panel data of 132 high- and low-income countries from 2014 to 2016, a random effect (RE) model is analyzed in comparison with cross-sectional analysis. To pursue the current research thoroughly, five elements of democracy that encompass the aspects of democratic institutions (election system, civil liberties, and government function) and the aspects of democratic culture (political participation and political culture) are selected. We find that elements of democracy are positively correlated with the environment in high-income countries. In low-income countries, on the other hand, it is found that the role of democracy in explaining the environmental quality appears to be very weak; only the effect of government function positively relates with the environment.
