环境规制对环保技术创新影响的实证研究

In this paper the indicators discharge standard-meeting rate of "three wastes"and pollution treatment efficiency,comprehensive utilization rate of"three wastes" and comprehensive utilization rate of solid waste were selected to obtain a comprehensive index by the principal component analysis with dimensional reduction to reflect environmental technology innovation level. Empirical research in impact of environmental regulation on environmental technology innovation was performed on this basis of Chinese provincial panel data from 2003 to 2012. The results indicated that the promotion effect of market incentives environmental regulation was more prominent than the mandatory environmental regulation on environmental technology innovation. A "inverted-U" curve between environmental Regulation intensity and environmental technology innovation level was found. The improvement in regional economic development level helped to promote the elevation of environmental technology innovation, foreign direct investment made a significantly positive impact on environmental technology innovation level while R&D investment can significantly promote environmental technology innovation level in the middle and west regions of China.
