摘要
为合理判断长江经济带11省(市)生态环境保护成效,通过构建环境绩效评价指标体系的方法开展环境绩效研究。考虑到经济发展水平对地区环保投入能力的影响,借助环境库兹涅茨曲线(EKC)与均值思想设定了不同经济发展水平下差异化的指标评价值,并结合熵值法计算出反映地区致力于生态环境保护努力程度的环境绩效指数(EPI)。结果表明:2011—2017年长江经济带的环境绩效整体呈上升态势,11省(市)EPI年均值由49.74增至61.70,但固体废物排放绩效有所下降;2017年11省(市)EPI从高到低依次为湖南(68.76)、安徽(66.62)、重庆(64.86)、四川(64.30)、浙江(61.26)、上海(60.96)、江西(59.53)、湖北(58.80)、贵州(58.68)、云南(57.65)、江苏(57.24),下、中、上游地区EPI平均得分分别是59.82、63.43、61.37,指数空间分布较为均衡;研究区域按照EPI与人均GDP可聚类划分为加速转型区、稳定发展区、缓慢提升区3种类型,针对不同类型地区分别提出差异化发展建议。研究采用的评价方法考虑了不同地区经济发展水平的差异,能在一定程度上反映各地区致力于生态环境保护的努力程度,可作为常规环境绩效研究的补充。
In order to assess ecological environmental performance of 11 provinces(municipalities)in Yangtze River Economic Belt(YREB)reasonably,the environmental performance research was carried out by constructing environmental performance index(EPI)system.Considering the influence of economic development levels on regional environmental protection input capacity,the differential index evaluation values under different economic development levels were proposed using the Environmental Kuznets Curves(EKC)and the mean value theory,and EPI of 11 provinces(municipalities)which reflected the degree of regional efforts to environmental protection were calculated by using entropy method.The results showed that from 2011 to 2017,the environmental performance of YREB as a whole showed an upward trend and the annual average EPI of 11 provinces(municipalities)in YREB was increased from 49.74 to 61.70,but the solid waste control performance declined.In 2017,the EPI score of 11 provinces(municipalities)ranking from high to low was Hunan(68.76),Anhui(66.62),Chongqing(64.86),Sichuan(64.30),Zhejiang(61.26),Shanghai(60.96),Jiangxi(59.53),Hubei(58.80),Guizhou(58.68),Yunnan(57.65)and Jiangsu(57.24),and the average EPI of downstream reaches,middle reaches and upstream reaches was 59.82,63.43 and 61.37,respectively,indicating that spatial distribution of environmental performance was relatively balanced.According to the clustering of EPI and GDP per capita,the 11 provinces(municipalities)were divided into three groups,i.e.accelerated transformation area,steady development area and slow upgrading area,to fit in different development schemes.The evaluation method reflected the efforts of each region to protect the ecological environment to a certain extent,by taking the differences of economic development level in different regions into account,which could provide effective supplement of conventional environmental performance research.
