摘要: 绿色发展是协调生态保护、促进经济发展和减少碳排放的有效方式,绿色发展正逐渐成为全球可持续发展目标和人类发展的重点。我国经济正进入高质量发展状态,资源和环境约束压力不断增强,而城市是现代经济增长的中心,绿色高效是我国城市转型发展的必由之路。文章采用超效率非期望SBM(slack based measure)模型测算长江经济带11省市绿色发展效率并探究长江经济带绿色发展效率的时空演化特征,然后与未考虑碳排放的长江经济带绿色发展效率进行对比分析,从时间和空间的角度评价绿色发展效率以及演化趋势和特征,并运用DEMATEL(decision making trail and evaluation laboratory technology)方法识别评价的关键影响因素。研究表明:长江经济带流域碳排放量逐年递增,碳排放对绿色发展效率存在一定的负面影响,在环境的约束下,下游的绿色发展效率值降幅明显;长江经济带绿色发展效率总体呈上升态势,各区域绿色发展水平差异显著,呈现下游>上游>中游的分布特征;从影响因素上看,产业结构、科研投入、对外开放、环境规制和植被覆盖率对碳排放视域下的绿色发展效率呈显著正向影响,绿色发展效率水平低主要表现在资源的过度消耗和环境污染物过度排放方面,其中环境问题主要是碳排放问题,正成为城市发展过程中提高绿色效率亟待解决的重点和难点问题。最后,为促进长江经济带流域生态环境改善,实现碳中和愿景提出相关政策建议,以保证更高效地利用资源,更强有力的保护生态环境,更好的建设长三角生态绿色一体化发展示范区。

Abstract: Green development, an effective approach to coordinating ecological protection, promoting economic development and reducing carbon emission, is becoming an objective of global sustainable development and human's development focus. China's economy is entering a quality developing status under a rising resources and environmental pressures. Cities are centers for modern economic growth that makes green efficiency an unavoidable way in urban transformation. This paper uses super-efficiency undesired SBM model  to measure the green development  efficiency of 11 Yangtze River economic zone provinces (cities) and their temporal-spatial evolution, compared with their green developing efficiencies without consideration of carbon emission, and applies decision making trail and evaluation laboratory technology (DEMATEL) to identify the key factors. Carbon emission in Yangtze River economic zone has been rising over years, impacting the green developing efficiency. The green developing efficiency has fallen largely in the down-stream of Yangtze River under the environmental constraints. Yangtze River economic zone shows a rising green developing efficiency, varying with regions, down-, upper- and middle-stream downwards. Factors such as industrial structure, research input, openness, environmental regulations and vegetation coverage rate positively play an outstanding role in green developing efficiency under perspective of carbon emission. A low green developing efficiency lies in over resource consumption and over pollution emission. Environmentally, carbon emission is becoming a hard point for increasing green developing efficiency amid urban development. This paper presents suggestions on improving ecological environment and reaching carbon neutralization to ensure a higher resource utilization and a stronger environmental protection, helpful in building Yangtze River delta as a green integrated developing demonstration. 

Key words: carbon emission, Yangtze River economic zone, green developing efficiency, super-efficiency undesired SBM, DEMATEL
