财政分权对中国环境治理绩效的合意性研究——基于系统GMM及门槛效应的检验

文章选择2007-2016年30个省(市、自治区)的面板数据,采用系统GMM和门槛效应模型探讨财政分权对环境治理绩效的影响。结论表明:从系统GMM检验来看,财政分权对环境治理绩效具有显著的负向抑制作用,并呈现出地区差异性。其中,东部表现为正向促进,而中西部表现为负向抑制。从门槛效应来看,财政分权对环境治理绩效存在显著的单一门槛效应。其中,自有收入分权表明,不论其分权化水平高低,均产生负向抑制作用;收入分权表明,在分权化水平较低时,产生负向抑制作用,在分权化水平较高时,抑制作用不显著;支出分权表明,在分权化水平较低时,促进作用不显著,在分权化水平较高时,产生负向抑制作用。最后,依据实证结论得出相关政策启示。

Desirability Study on the Performance of Environmental Governance in China Based on Fiscal Decentralization: Inspection Based on System GMM and the Threshold Effect

This article makes use of the system GMM and the threshold panel system to study the relationship between fiscal decentralization and environmental governance performance based on the panel data of 30 provinces (municipalities and autonomous regions) from 2007 to 2016 in our country. The conclusion shows that: from the perspective of the system GMM test, the fiscal decentralization of the national sample has a significant negative effect on environmental governance performance, and has regional differences, of which the eastern region is positive and the central and western regions are negative. From the threshold effect, fiscal decentralization has a significant single threshold effect on environmental governance performance. From the perspective of discretionary income, it shows that regardless of the level of decentralization of the discretionary income, there is a negative impact. When the income decentralization is low, there is a negative impact; when the income decentralization is high, the negative impact is not significant. The perspective of expenditure shows that when the decentralization of expenditure is low, the negative impact is not significant; when the decentralization of expenditure is high, there is a negative impact. Finally, based on the empirical conclusions, we put forward some policy implications.
