文章运用三阶段DEA模型对中国地区2012年的工业水污染治理效率进行测评,研究发现,不排除环境变量和随机因素的干扰会导致中国省区工业水污染治理效率的高估,而剔除环境和随机因素后发现,中国省区工业水污染治理效率偏低,只有0.682,规模无效率是阻碍工业水污染治理效率提升的关键因素。研究还发现,东部地区工业水污染治理效率较高,而中西部则较低,这主要由三大地带间的规模效率差异所致。将中国省区工业水污染治理效率按照纯技术效率和规模效率分类后发现,中国没有“低高型”省区,多数省区是“双低型”或“高低型”。
文章運用三階段DEA模型對中國地區2012年的工業水汙染治理效率進行測評,研究髮現,不排除環境變量和隨機因素的榦擾會導緻中國省區工業水汙染治理效率的高估,而剔除環境和隨機因素後髮現,中國省區工業水汙染治理效率偏低,隻有0.682,規模無效率是阻礙工業水汙染治理效率提升的關鍵因素。研究還髮現,東部地區工業水汙染治理效率較高,而中西部則較低,這主要由三大地帶間的規模效率差異所緻。將中國省區工業水汙染治理效率按照純技術效率和規模效率分類後髮現,中國沒有“低高型”省區,多數省區是“雙低型”或“高低型”。

By using three-stage DEA model,the paper evaluates treatment efficiency of industrial water pollution of China in 2012. The study shows that:although the interference of environment variables and random factors would lead to an overestima-tion of treatment efficiency of industrial water pollution in China’s provinces and autonomous regions,the treatment efficiency of industrial water pollution is still lower after eliminating environmental and stochastic factors, which is only 0.682, and the scale inefficiency is the essential element to hinder improvement of treatment efficiency of industrial water pollution. The study also finds that the treatment efficiency of industrial water pollution in eastern region is higher than that in central and western re-gions,which is caused mainly by the differences of scale efficiency among the three regions. After classifying the treatment effi-ciency of industrial water pollution in China’s provinces and autonomous regions according to pure technical efficiency and scale efficiency, the study indicates that there is no“low-high type”provinces and autonomous regions, most of them are“low-low type”or“high-low type”in China.
