中国省际环境效率评价及其影响因素实证研究

Empirical Study on Determinants of Environmental Efficiency of China

通过运用基于DEA理论考虑规模收益的BCC模型计算出我国大陆30个省份2014年的环境效率,并采用多元回归的方法对环境效率影响因素进行实证分析,挖掘影响环境效率的关键因素,并从效率视角对环境库兹涅茨曲线进行检验。实证结果表明经济增长与环境效率之间呈倒"U"型曲线,这与传统的环境库兹涅茨曲线的含义正好相反。同时研究发现图书馆数量、节能环保预算支出、农村现金消费支出以及外商投资总额对环境效率有正面影响,而固定资本投资、城市现金消费支出、煤炭储量、石油储量以及第二产业增加值对环境效率有负面影响。

This article analyses environmental efficiency factors of 30 mainland provinces of China in 2014and discover the key factors affecting the environmental efficiency, and examine environmental Kuznets curve from a new perspective. This article attainsan inverted U-shaped curve between economic growth and environmental efficiency, which is opposite tothe meaning of traditional environmental Kuznets curve. And the results show that the number of library, the energy saving budgetary expenditures, the rural cash consumption expenditure and the total foreign investmenthas a positive impact on the environmental efficiency of a, region. However, the fixed capital investment, urban cash consumption expenditure, coal reserves, oil reserves and the secondary industry has a negative impact on the environment efficiency.
