长三角城市群高质量绿色发展的均衡性特征及障碍因素

从绿色核心动力、环境基底、创新产业、发展绩效四个维度构建评价体系,运用CRITIC赋权、核密度估计、重心—标准差椭圆等方法,从均衡态、均衡度、均衡熵角度探讨长三角城市群高质量绿色发展的均衡状况,并分析其障碍因素。结果表明：（1）高质量绿色发展存在明显的空间差异,但未出现空间极化现象;总体格局呈西北—东南向,重心位于南北居中、东西偏东的位置。（2）高质量绿色发展总体水平较为均衡,但其中创新维度均衡度较低;城市内部均衡度存在明显的省域分化,沪苏浙城市明显优于安徽省内城市。均衡熵表明多数城市系统协调度有优势,具备一定发展潜力。（3）创新水平、环境质量、土地集约、现代产业等是高质量绿色发展普遍存在的障碍因素。坚持创新驱动,建设现代产业体系,加强国土空间治理是长三角城市群高质量绿色发展的紧迫任务。

Balanced characteristics and obstacle factors of high-quality green development in Yangtze River Delta Urban Agglomeration

Under the strategic background of high-quality integration of Yangtze River Delta and ecological priority and green development of Yangtze River Economic Belt, it is of great significance to explore the high-quality green development of Yangtze River Delta Urban Agglomeration. This paper constructs a high-quality green development evaluation system from four dimensions of green core power, green innovation industry, green environment base and green development performance. Based on the methods of critical weighting, kernel density estimation, center of gravity standard deviation ellipse and other methods, the equilibrium state, equilibrium degree and equilibrium entropy of high-quality green development of 27 cities in Yangtze River Delta Urban Agglomeration are discussed. The results show that: (1) Generally, the high-quality green development level of the urban agglomeration presents a northwest-southeast pattern and the gravity is located in the east of the center of the region. There are obvious spatial differences in the high-quality green development, but there is no spatial polarization. (2) From the regional perspective, the overall level of high-quality green development is relatively balanced, but with relatively low innovative dimension. From the perspective of city, there is obvious provincial differentiation in the degree of equilibrium, and Shanghai and the cities in Jiangsu and Zhejiang are obviously better than Anhui province. Equilibrium entropy shows that most cities have advantages in coordination degree of high-quality green development and have certain development potential. (3) Innovation level, environmental quality, land intensification and modern industry are common obstacles to high-quality green development. Based on this, the main obstacle types of cities are summarized and their specific obstacles are defined too. Adhering to innovation driven development, building a modern industrial system, strengthening the governance of land space, promoting the intensive, efficient and sustainable use of land, and maintaining a reasonable degree of balance and coordination are the urgent tasks to further promote the high-quality green development in the Yangtze River Delta Urban Agglomeration in the future.
