我国工业领域环保投资效率及其影响因素分析

Efficiency and Main Factors of Environmental Investment in Industry

运用数据包络分析方法（DEA）,以2004~2012年我国30个省市自治区的面板数据为样本,对我国工业领域环保投资效率进行测算,并分析其主要影响因素。研究发现,我国工业领域环保投资效率在区域上呈＂中部高、东西部低＂的格局,这与二产比例紧密相关;地方政府环保支出是影响效率的重要因素,工业企业还没有担起环保责任主体的应有作用。此外,工业领域环保投资过多关注＂增量＂工业项目,或许是环境质量没有得到预期改善的原因之一。

Using Chinese provincial panel data from 2004 to 2012,the environmental investment efficiency in industry was measured under data envelopment analysis（DEA）model and the main factors affecting the efficiency was analyzed.It was found that the environmental investment efficiency among different provinces was higher in middle part,lower in east and west parts,which was highly correlated with the proportion of secondary industry.Environmental expenditure of local governments was also an important factor of the environment investment efficiency in industry,showing that industrial enterprises have not taken enough responsibility.Besides,the present environmental investments in industry focus too much on incremental industrial projects,which seem to be one explanation of why the country failed to improve the environment as expected.
