基于三阶段DEA方法的我国海洋污染治理效率研究

Efficiency of marine pollution treatment in China based on three-stage DEA analysis

利用收集到的海洋环境数据,构建中国海洋污染治理的投入产出指标体系,运用三阶段DEA方法,分析我国2002—2011年的海洋污染治理效率。结果表明:规模不经济导致海洋污染治理效率总体水平不高;外部环境因素在技术、经济和社会三方面对海洋污染治理效率影响显著。基于以上研究分析,对我国海洋污染治理存在的问题提出相关政策性建议,以助于提高我国海洋污染治理的效率。

The input-output index system for marine pollution treatment in China is established by use of the collected data of marine environment. The three-stage DEA is employed to analyze the efficiency of marine pollution treatment in China from 2002 to 2011. The results show that:( 1) the diseconomy of scale leads to the low level of the overall efficiency of the marine pollution treatment;( 2) the external environmentalfactors are remarkable for the efficiency of the marine pollution treatment in the technical, economic and social aspects. Based on the above analysis, the relevant policy suggestions are put forward in order to improve the efficiency of the marine pollution treatment in China.
