摘要
为优化环保投资结构,有效使用环保投资,借助于数据包络分析方法 (DEA)对陕西省2002～2009年的环保投资绩效进行实证分析。实证分析结果表明,这些年陕西省环保投资技术效率的均值为0.985,其在规模效率上处于规模合理或规模递增阶段占75%,在技术效率上处于最佳和有效状态的占75%。说明陕西省环保投资绩效保持在一个较好的水平,但陕西省环保投资还没有充分发挥作用,环保投资对经济发展和社会进步的贡献偏低,人才队伍建设力度水平亟待提高。陕西省政府可采取一些措施使陕西环保绩效进一步提高。
In order to optimize the structure of the investment in environmental protection and the efficient use of the environmental protection investment, the empirical analysis of the environmental protection investment in Shaanxi Province during 2002 -2009 is conducted by means of the data envelopment analysis （DEA）. It shows that the tech- nical efficiency of its investment is an average of 0. 985, 75% of the investment attains a reasonable scale efficiency, or with an ascending scale. The investment with an optimum and effective technical efficiency also accounts for 75% of the total investment. Therefore the performance of the environmental protection investment of the province is main- tained at a good level. However, its full advantage is yet exerted, with its low contribution to the socio-economic de- velopment. The capacity building is in an urgent need. Shaanxi Provincial Government could take some measures to improve its environmental performance.
