双重环境规制下政府经济竞争对绿色高质量发展的影响

利用我国2008~2018年277个地级及以上城市面板数据，基于EBM模型与GML指数测度并分析绿色全要素生产率（GTFP），在此基础上系统分析双重环境规制下政府经济竞争与GTFP间存在的非线性关系.结果发现：绿色技术进步是中国GTFP增长的主要引擎，但各地区的驱动力不尽相同；政府经济竞争对GTFP具有显著的抑制作用，并存在隐性规制的单门槛效应，但地区间存在差异，西部和东北地区存在隐性规制单门槛，而东部地区门槛效应不显著；外商直接投资和科技投入支出均造成辖区内GTFP损失，产业结构在一定程度上缓解了环境问题，但存在区域异质性.

Influence of government economic competition on green high-quality development under dual environmental regulations

Taking the panel data of 277 cities that are prefecture-level and above in China from 2008 to 2018 as examples, this article measured and analyzed the green total factor productivity (GTFP) based on the EBM model and the GML index. On this basis, this research systematically analyzed the nonlinear relation of dual environmental regulations in the relationship between government economic competition and GTFP. The results indicated that green technological progress was the main engine driving China's GTFP growth, but the driving forces of each region were different. Furthermore, government economic competition showed a significant inhibitory effect on GTFP, and there existed a single threshold effect of implicit regulation among them. On the other hand, there were variations in different regions. Specifically, it showed that there was an implicit regulatory single threshold in both the western and northeastern regions, while the eastern region did not demonstrate a significant threshold effect. Furthermore, foreign direct investment and technology input expenditure caused GTFP losses in the jurisdiction. At the same time, industrial structure effectively alleviated environmental problems to a certain extent, but with regional heterogeneity.
