摘 要:从DEA和SFA法两种不同角度,运用DEA效率模型对2006-2017年广东省21地市进行相对和绝对环境效率综合评价.研究表明,广东省绝对环境效率整体呈现提高态势,各地市环境效率均值从均匀分布逐步向珠三角地带聚集,其中,广州、深圳、珠海和中山一直呈现高效态势,21地市环境效率存在β趋同,而各地市相对环境效率则空间上呈现出逐渐减少的分布特征.The ecological environment problem is the focus of scholars in recent years. In the present study, the efficiency model is used to comprehensively evaluate the environmental efficiency of Guangdong Province in 2006-2017, and the Tobit regression model is used to explore the factors affecting the environmental efficiency of Guangdong Province. The results show that the absolute environmental efficiency of Guangdong Province is continuously improved, but there are differences in the 21 cities. According to the K-means clustering analysis, the uniform distribution is gradually concentrated in the central coastal zone;the environmental efficiency of the effective areas is relatively reduced gradually. The areas that have always been effective are Guangzhou, Shenzhen, Zhuhai and Zhongshan while the environmental efficiency of 21 cities has β convergence.
