财政环保支出与空气治理效果——基于省际面板数据的实证分析

Empirical Analysis of Fiscal Expenditure on Environmental Protection and Air Control Effect Based on Interprovincial Panel Data

随着空气污染程度的加深,国家将节约资源环境保护提升到了战略高度,2007年开始,财政支出将环保支出单列为一项财政预决算项目,近年来各个省份的财政环保支出逐年加大,但是空气质量是否因此得到改善还无定论。使用固定效应回归模型检验了地方财政环保支出对空气质量的影响效果,结果显示地方财政环保支出对空气质量没有显著影响,而人口数量、民用汽车保有量和工业增加值占GDP比重对空气质量的影响在统计上是显著的。

With the deepening of air pollution, the nation has raised the level of environmental protection to a strategic level. Since 2007, the fiscal expenditure for environmental protection has been listed as a single fi-nancial budget and final account item. In recent years, the fiscal expenditure on environmental protection has in-creased year by year. Because of the existence of individual effect, the fixed effect regression model is used to test the effect of local fiscal expenditure on air quality. The results show that local fiscal expenditure on environ-mental protection has no significant impact on air quality, while the impact of population and private car owner-ship on air quality is statistically significant.
