摘要: 文章采用包含污染排放的环境数据包络分析(DEA)模型,测量了2010—2020年丝绸之路经济带节点城市的环境效率,结果显示:1)10个节点城市总体环境效率不高,环境效率差距大,呈现东、中、西部的层级变化,突出了区域间减排和环境技术促进方面跨区域合作的必要性;2)东、中部节点城市的环境效率差距逐年开始缩小,呈现一定的趋同趋势。此外,利用Tobit模型分析了影响环境效率的因素,发现经济规模、国际贸易和技术进步促进了环境效率,而产业结构、区域特征则对环境效率没有显著影响。最后,根据实证分析结果,提出了减少区域污染排放和提高我国环境效率的若干建议。

Abstract: This paper uses DEA model containing environmental pollution data to measure the environmental efficiency of node cities along China ‘s Silk Road Economic Belt During 2010 to 2020. The results show that ten node cities are low in overall environmental efficiency, largely variable among eastern, central and western, marking a necessity for regional emission reduction and across-regional cooperation boosted by environmentally technical advances.  Environmental efficiency gap in eastern and central node cities is diminishing to the same level.  This paper applies Tobit model to analyze the factors of environmental efficiency, which is promoted by economic scale, international trade and technical advances, little by industrial structure and regional features. This paper presents suggestions on reducing pollution emission and on increasing China ‘s environmental efficiency.
