Heterogeneous Environmental Regulations And Green Economic Efficiency In China: The Mediating Role of Industrial Structure
Abstract As the largest emerging economy, China has been experiencing significant environmental problems. To sustain green economic efficiency and modernize industrial structure, China has devised several environmental regulations. While, previous studies have obtained insightful conclusions on this subject, others have presented the reverse arguments, thereby leaving gaps in the literature. This study therefore analyzes the effects of heterogeneous environmental regulations on green economic efficiency in China while taking industrial structure as a mediator over the period 2003-2017. The green economic efficiency was estimated through slacks-based direction distance function (SBM-DDF) model which considers slacks and avoids overestimation. The results of dynamic panel two-stage system generalized method of moments (GMM) show that control-and-command regulation, market-based regulation and voluntary regulation are conducive to China’s green economic efficiency. Regarding spatial heterogeneity, control-and-command and voluntary regulations significantly promote green economic efficiency of inland provinces while the effect is insignificant in coastal provinces. Additionally, market-based regulation promotes green economic efficiency by advanced and rationalized industrial structure. Control-and-command regulation accelerates green economic efficiency only through advanced industrial structure. Voluntary regulation yields positive effect on green economic efficiency through advanced industrial structure and negative effect through rationalized industrial structure. Finally, a number of policy implications are provided.
