长江经济带协调性均衡发展水平对比及优化路径研究

Comparative Study on Level of Coordinated and Balanced Development of Yangtze River Economic Belt and Optimization Path

党的二十大提出我国目前发展不平衡不充分的问题仍然突出,在未来工作中对区域协调发展提出了更高的要求。推动长江经济带区域协调性均衡发展是我国“提高发展的平衡性、协调性和包容性”的重要路径之一,也是实现我国共同富裕以及高质量发展的重要途径。基于调整后的协调性均衡发展指数评价指标体系,应用2019及2020年统计数据,利用多种定量分析方法试图揭示与对比长江经济带协调性均衡发展的现状,主要结论如下:(1)受新冠肺炎疫情影响,相较于2019年,除部分城市外,2020年长江经济带各城市的协调性均衡指数呈现出缓速上升的趋势,且2020年极差较上年有所减小,但区域间依然存在较大差异;(2)从二、三级指标来看,基本公共服务、公共基础设施、产业协调、市场统一以及经济协调分项是导致长江经济带各城市间差异产生的主要原因;(3)基于长江经济带各城市协调性均衡发展指数的空间集聚特征,利用K-cluster聚类法将110个城市划分为5种类型区,并针对上述类型区分别提出了差异化的调控策略和优化路径。

The Party’s twenty Congress pointed out that the problem of unbalanced and inadequate development was still severe and put forward stricter requirements for regional coordinated development in the future.Promoting the coordinated and balanced regional development of the economic belt along the Yangtze River is an important way to“improve the balance,coordination and inclusiveness of development”and an important approach to achieve common prosperity and high-quality development.Based on the adjusted coordinated and balanced development index evaluation index system,this study used statistical data in 2019 and 2020,and employed a variety of quantitative analysis methods to reveal and compare the current situation of coordinated and balanced development of the Yangtze River Economic Belt.The main conclusions were as follows:(1)Compared with 2019,there was an increase in 2020 in the absolute value of the coordination equilibrium index of 110 cities at the prefecture level and above in the Yangtze River Economic Belt.It was also observed that the range decreased compared with 2019,and there were still large differences among different regions;(2)From the second and third level indicators,public basic services and public infrastructure in the equilibrium degree,industrial coordination,and market unity and economic coordination in the integration degree were the main reasons for the differences among 110 cities.(3)The 110 cities in the Yangtze River Economic Belt were divided into 5 types based on the K-cluster clustering method.Differentiated regulation strategies and optimization paths were proposed for these 5 types of cities.
