本文采用非期望产出的超效率SBM-DEA模型测算2000年—2017年新疆14个地州市（不包含兵团城市）的绿色经济效率,并通过时空分析归纳出新疆绿色经济效率的演化特征,得出以下结论：全疆大部分地州市资源消耗指数呈逐年上升趋势,环境污染指数经历了先升后降两个阶段;新疆绿色经济效率平均值呈先下降后波动上升态势,效率值围绕0.4上下波动;分地区来看,北疆地区绿色经济效率平均值高于全疆平均值,东疆和南疆地区低于全疆平均值;在空间相关性上表现为2007年以后新疆各地州市绿色经济效率在空间上出现集聚现象,且呈现出中部热、东部次冷、西南部冷的格局。为此,新疆应提高资源利用效率,制定因地制宜的绿色发展模式,优化产业结构,强化环境规制,实现新疆经济可持续发展。
This paper uses the undesired output super-efficiency SBM-DEA model to measure the green economic efficiency of 14 regions and cities in Xinjiang (excluding XPCC) from 2000 to 2017, and summarizes the development features of green economic efficiency in Xinjiang through space-time analysis. The following conclusions are drawn: The resource consumption index of most prefecture-level cities in Xinjiang is increasing year by year; the environmental pollution index has experienced two stages: first up, then down; the average value of green economy efficiency in Xinjiang decreased first and then fluctuated to rise with the efficiency value fluctuating around 0.4; by region, the average value of green economic efficiency in northern Xinjiang is higher than the average in Xinjiang, while the average in eastern and southern Xinjiang is lower than the average in Xinjiang; the spatial correlation shows that after 2007 in all parts of Xinjiang, the city has spatial agglomeration, and Xinjiang's green economic efficiency generally shows a pattern of hot in the middle, sub-cold in the east, and cold in the southwest. To this end, Xinjiang should reduce resource investment and environmental pollution, formulate a green development model that adapts to local conditions, optimize industrial structure, strengthen environmental governance capabilities, and improve environmental laws and regulations to achieve green and high-quality development.
