摘要:
当前以GDP增长为主的地方政府绩效考核体系,对环境保护等公共服务激励不足,导致地方政府的环境保护绩效不理想. 在参考资源、环境和经济综合评价相关研究成果的基础上,采用经济发展与污染物排放关联分析的方法,构建了PEI(Pollution & Economy Index,污染与经济指数),从环境代价和经济效益两个维度评价区域环境与经济发展的协调程度. 以2007—2016年《中国统计年鉴》和《中国环境统计年鉴》数据为基础,通过计算人均GDP和人均污染物排放当量(COD、氨氮、SO2、NOx),对我国30个省(市)区的环境与经济绩效(不含港澳台和西藏的数据)进行了分析与评价. 结果表明,2006—2015年全国人均GDP与人均污染物排放当量的比值总体上呈上升趋势,多年平均增长率高达13.66%,中国的总体环境与经济效益有所改善. 从PEI全国排名来看,PEI优于全国平均水平的省区数量有所增加(由原来的9个增加到12个). 2015年PEI排名前三的依次为北京、上海和天津,而排名落后的3个省区依次为宁夏、新疆和甘肃.研究显示,PEI指标计算简单,可对不同发展阶段的省区进行相对客观的评价,具有较高的稳定性和可操作性,对优化现有政府绩效考核指标具有重要的参考价值.

Environment and Economy Performance Evaluation of China Based on PEI
罗宏,et al
Abstract:
Local government performance evaluation systems leading to environmental protection performance of local governments were not ideal, especially for public services such as environmental protection incentive were not strong enough. Referencing the resources, environment and economy comprehensive evaluation relevant research results, the economic development and pollution emissions correlation analysis method is put forward and the PEI (Pollution & Economy Index) is constructed. The coordination degree of regional environment and economic development was evaluated from two dimensions: environmental cost and economic benefit. Based on the data (from the year 2007 to 2016) of China statistical yearbook and China environmental statistics yearbook, environmental and economic performance of 30 provinces in China were analyzed and evaluated by calculating per capita GDP and per capita pollutant emission equivalent (COD, ammonia nitrogen, SO2, NOx). The results show that: The ratio between national per capita GDP and per capita emission of pollutant equivalent had been rising, with the annual average growth rate of 13.66 percent from the year 2006 to 2015, which indicating that the overall environment and economic benefits of China had improved. According to PEI''s national ranking, the number of provinces with PEI value higher than national average had increased from 9 to 12 from the year 2006 to 2015, which indicating overall environment and economic performance of provinces in China had improved. For PEI ranking, the top three provinces were Beijing, Shanghai and Tianjin versus the lower ranked three provinces are Ningxia, Xinjiang and Gansu. Case study shows that the PEI index calculation is simple and can be used on different development stage of the provinces and autonomous regions, which has relatively objective evaluation result and high stability and maneuverability. PEI has important reference value for optimizing existing performance evaluation indicators of local governments.
