长江经济带区域协调发展格局及影响因素组态研究

Study on Regional Coordinated Development Pattern and Influencing Factors of Configuration of the Yangtze River Economic Belt

长江经济带是我国东中西部互动合作的协调发展带,但区域内部发展不平衡问题突出,如何促进其区域高质量协调发展已成为热点研究内容.从区域协调发展的内涵和新时代区域协调发展的目标入手,构建了区域协调发展的评价指标体系,运用熵值法、局部协调发展测度模型、障碍度模型、定性比较分析(QCA)等方法对2005-2020年长江经济带110个城市的区域协调发展空间格局与影响因素进行组态分析.结果表明:①从整体变化趋势来看,长江经济带区域协调发展水平呈现提升趋势,除科技创新和公共服务系统,其余4个子系统(经济发展、人民生活、基础设施、生态环境)区域协调发展水平不断提高.②2005-2020年长江经济带区域协调发展类型的空间分布呈现由“屋脊式”向“组团式”发展.③高区域协调发展水平形成路径共有5条,分别为经济主导下的多元驱动型、经济科技助力下的生态环境基础设施公共服务三驱型、生态环境单驱型、经济发展与科技创新双驱型以及人民生活与基础设施双驱型.

The Yangtze River Economic Belt is a coordinated development belt of interaction and cooperation among the eastern,central and western regions of China.However,the imbalance of development within the region is prominent.How to promote the high-quality coordinated development of the region has become a hot research topic.Starting from the connotation of regional coordinated development and the goal of regional coordinated development in the new era,the evaluation index system of regional coordinated development was constructed.Using entropy method,local coordinated development measure model,obstacle degree model,qualitative comparative analysis(QCA)and other methods,this paper analyzes the spatial pattern and influencing factors of regional coordinated development of 110 cities in the Yangtze River Economic Belt from 2005 to 2020.The results show that:①From the overall trend of change,the level of regional coordinated development presented an improving trend.Except scientific and technological innovation and public service system,the level of regional coordinated development of the other four subsystems was improving.②From 2005 to 2020,the spatial distribution of regional coordinated development types in the Yangtze River Economic Belt developed from“roof type”to“cluster type”.③There were five paths to form the high level of regional coordinated development,which were the multi-drive type under the economic dominance,the three-drive type of ecological environment-infrastructure-public service under the assistance of economy and technology,the single-drive type of ecological environment,the double-drive type of economic development and scientific and technological innovation,and the double-drive type of people s life and infrastructure.
