基于SBM-Malmquist的长三角城市群绿色发展效率测度与评价

Evaluation and analysis of green development efficiency in Yangtze River Delta urban agglomeration based on SBM-Malmquist

利用熵值法、SBM-Malmquist模型对2005—2018年长三角核心城市群绿色发展效率及全要素生产率进行了评价,并检验了其收敛性。结果表明,样本期间长三角城市群整体的绿色发展效率较高,主要受技术进步的影响,总体呈现上升趋势,区域内总体差距在逐年缩小,安徽省绿色发展水平总体落后于区域内其他省市;区域内城市群间绿色发展效率不均衡,各省份内核心城市与外围城市之间的地域差异较为明显。只有推动长三角地区绿色发展效率同步提升,才实现区域绿色一体化发展。

This paper used the entropy method and SBM-Malmquist model to evaluate the green development efficiency and total factor productivity of Yangtze River Delta core urban agglomeration from 2005 to 2018,and tested its convergence. The results showed that during the sample period,the overall green development efficiency of the Yangtze River Delta urban agglomeration was relatively high.It showed an upward trend under the influence of technological progress,and the overall gap within the region was narrowing year by year. And the green development level of Anhui province was generally behind other provinces and cities in the region. The green development efficiency of the urban agglomeration in the region was not balanced,and the core cities and peripheral cities in each province were different. The regional differences between them were obvious. The development of regional green integration can be realized by promoting the synchronous improvement of the efficiency of green development in the Yangtze River Delta region.
