财政分权对环保投资效率的影响研究——基于DEA-Tobit模型的分析

延续财政分权对环境质量影响的研究,讨论财政分权对环保投资效率的影响.基于中国2004~2014年30个省份的面板数据,在DEA-Tobit模型的研究框架下,测度了各个省份多种类型的环保投资效率,并进一步讨论了财政分权对环保投资效率的影响.实证结果发现,财政分权不利于环保投资效率的改进,特别是不利于建设项目"三同时"环保投资效率、工业污染源治理环保投资效率,以及企业来源环保投资效率的改进.进一步考虑到地区异质性因素,以各地区环保投资额作为门槛变量的分析同样支持上述结论.

Fiscal decentralization influence on environmental investment efficiency: Analysis based on DEA-Tobit model

This paper investigates the effect of fiscal decentralization on environmental investment efficiency, further considering the study on the impact of fiscal decentralization on environment quality. Based on the panel data of 30provinces in China from 2004 to 2014, the environmental investment efficiency is measured under DEA (Data Envelopment Analysis) method, and the relationship between fiscal decentralization and environmental investment efficiency is investigated by a panel Tobit model. The empirical results show that fiscal decentralization is not conductive to the improvement of environmental investment efficiency especially for the "Three Simultaneous" of construction projects, industry pollution sources control, as well as the improvement of corporate environmental protection investment efficiency. Considering the regional heterogeneity factors, further studies that the aggregate environmental investment is selected as a threshold variable also support the conclusion.
