关于财政分权与经济增长对环境污染的影响研究

文章基于2004—2016年我国31个省份的面板数据,利用固定效应模型,尝试从财政收入分权与财政支出分权两个维度研究财政分权与经济增长对环境污染的影响.实证研究表明:无论是以财政收入分权还是以财政支出分权衡量的财政分权指标都会增加环境污染的程度,即财政分权与环境污染呈正相关关系,同时财政支出分权对环境污染的影响要大于收入分权.以SO2排放量衡量的环境污染指标与以人均GDP衡量的经济增长指标之间呈倒"U型"关系,并且已经越过环境库兹涅茨曲线的拐点.研究还发现,财政分权与经济增长的交叉项与环境污染呈正向关系;产业结构与环境污染呈正比,其中第二产业影响最深;对外开放与环境污染呈负向关系但不显著.鉴于此,文章围绕实证结果提出相关性建议.

Research on the Impact of Fiscal Decentralization and Economic Growth on Environmental Pollution

Based on the panel data of 31 provinces in China from 2004 to 2016,this paper uses the fixed effect model to study the impact of fiscal decentralization and economic growth on environmental pollution from two dimensions of fiscal revenue decentralization and fiscal expenditure decentralization. The empirical study shows that both fiscal revenue decentralization and fiscal expenditure decentralization can increase the environmental pollution degree; that is,fiscal decentralization is positively correlated with environmental pollution,and fiscal expenditure decentralization has a greater impact on the environment than fiscal revenue decentralization.The relationship between environmental pollution measured by SO2 emission and economic growth measured by per capita GDP presents an inverted " U" curve,and has crossed the turning point of EKC. It is also found that the cross term between fiscal decentralization and economic growth is positively correlated with environmental pollution. The industrial structure is positively proportional to environmental pollution,among which the secondary industry has the greatest influence. Opening has negative relationship with environmental pollution,but it is not significant. In view of this,this paper puts forward some relevant suggestions around the empirical results.
