Abstract: This paper constructs a theoretical and analytical framework for the economic effects of environmental regulations, and tests the "emission reduction" and "efficiency enhancement" effects of environmental regulations by applying the Chinese urban panel data and the dynamic spatial panel model. It is found that the environmental regulations in China has the economic and spatial spillover effects of "emission reductions only without economic efficiency", and the conclusion is still unchanged with a series of robustness tests. A further heterogeneity study reveals that the environmental effects of "emission reductions only without economic efficiency" are validated in those three parts of China, i.e., East, Central and West. After the international financial crisis, the "emission reductions" effects brought about by the environmental regulations have significantly intensified, but only with an increased "compliance cost", and no "innovation effects". The effects of "emission reductions only without economic efficiency" can only be improved efficiently through speeding up the restructuring of industries. The relationship between economic development and energy efficiency presents a trend of U shape, and China is on the left side of the "U", and so far the Kuznets environmental curve has not been confirmed by Chinese city data yet.
