    摘要:

    基于2007—2018年长江经济带11个省(市)面板数据,利用Super-SBM模型测算生态效率,并进一步通过分解ML指数和测度投入产出冗余率分析引起效率波动的因素。结果表明:长江经济带区域生态效率未达到有效水平,区域化差异显著,呈现下游大于中游大于上游的格局,且下游区域生态效率水平远高于中游和上游;浙江省、上海市生态效率达到DEA有效;资源冗余情况大体和生态效率呈负相关,环境污染是效率损失的首要原因,亟需通过优化产业结构、促进产业协调发展实现资源节约与环境保护;技术进步是区域全要素生产率的主要推动因素,技术效率仍需改善。基于动静结合的生态效率时空演化分析,提出提升长江经济带生态效率的对策建议。

    Abstract:

    Based on the panel data of 11 provinces and cities in the Yangtze River economic zone from 2007 to 2018, the Super-SBM model is used to measure the ecological efficiency, and the factors causing the efficiency fluctuation are further analyzed by decomposing the ML index and measuring the redundancy ratio of input and output. The results show that the regional ecological efficiency in the Yangtze Rivereconomic zone has not reached the effective level, and the regional differences are significant, showing a pattern of “downstream>midstream>upstream”, and the level of ecological efficiency in the downstream region is much higher than that in the middle and upper reaches. The ecological efficiencies in Zhejiang Province and Shanghai City have reached DEA efficiency. The resource redundancy is generally negatively related to the ecological efficiency, and the environmental pollution is the primary cause of efficiency loss. It is urgent to optimize the industrial structure and promote the coordinated development of the industry to achieve resource conservation and environmental protection. The technological progress is the main driver of the regional total factor productivity, and the technical efficiency still needs to be improved. Based on the temporal and spatial evolution analysis of dynamic and staticcombination, some suggestions and countermeasures are put forward for improving the ecological efficiency in the Yangtze River economic zone.
