新发展理念下长三角经济高质量发展的测度与评价

Measurement and Evaluation of the High-quality Economic Development of the Yangtze River Delta Under the New Development Concept

采用熵值法测算2005—2018年长三角41个城市的高质量发展水平,利用非参数核密度估计法和GIS技术分别对综合、分项指数的时空演变规律和区域差异进行评价分析。结果显示:长三角城市群高质量发展水平2005—2018年稳步提升,城市间差距有所缩小,但在三省一市、都市圈内依然存在外部发展差异大、内部发展不充分和发展质量较低等问题;在空间上呈现出“中心—外围”的结构特征,直辖市、省会城市和经济强市为中心城市,经济高质量发展水平明显优于其他城市;分维度看,绿色发展为长三角城市群经济高质量发展最主要的动力源泉,协调、综合质效也是其优势维度,创新、开放和共享则是短板维度,其中创新发展对高质量发展水平的贡献率最低;相比于江浙沪地区城市,安徽省城市创新、协调、开放发展的不平衡问题突出,但在共享发展方面处于领先水平。

The entropy method is used to measure the high-quality development level of 41 cities in the Yangtze River Delta from 2005 to 2018,and the non-parametric kernel density estimation method and GIS technology are used to evaluate and analyze the temporal and spatial evolution laws and regional differences of the comprehensive and subindices respectively.The results show that:the high-quality development level of the Yangtze River Delta urban agglomeration has steadily improved from 2005 to 2018,and the gap among cities has narrowed,however,there are still large external development differences,insufficient internal development and low development quality in the three provinces,one city,and metropolitan areas;in terms of space,the level of high-quality economic development centered on municipalities,provincial capitals and economically strong cities is significantly better than other cities,showing the structural characteristics of“center-periphery”;from a subdimension perspective,green development is the main source of driving force for the high-quality economic development of the Yangtze River Delta urban agglomeration,coordination and comprehensive quality and efficiency are also its advantages,but innovation,openness and sharing are shortcomings,and among them,innovation and development have the lowest contribution rate to high-quality development;compared with cities in Jiangsu,Zhejiang and Shanghai,the unbalanced problem of innovation,coordination and open development in Anhui is prominent,but it is at the leading level in terms of shared development.
