Abstract:Based on the 2009-2017 provincial panel data of China's industry, systematically construct an evaluation index system for the high-quality development of China's regional industries,and incorporate the heterogeneous threshold of environmental regulations into innovation-driven high-quality industrial development Framework to examine the nonlinear impact mechanism of innovation vitality on industrial high-quality development under the threshold of environmental regulation in different regions. The research found that the current level of high-quality development of regional industries is low, and the regional heterogeneity is significant. Interestingly, the effect of innovation vitality on the high-quality development of regional industries has a significant heterogeneous threshold effect of environmental regulation: A low level of environmental regulation is not conducive to stimulating innovation vitality and promoting high-quality industrial development, and as the level of environmental regulation increases and exceeds the critical value, it effectively stimulates the driving effect of innovation vitality to a certain extent, thereby increasing the regional industrial high Quality development level.
