基于主成分分析的城市竞争力测度与评价——以江西省11地市为例
Urban Competitiveness Measurement and Evaluation Based on Principal Component Analysis—Taking 11 Cities in Jiangxi Province as an Example

本文采用2022年江西省城市年鉴数据，构建江西省城市发展竞争力的指标体系，采用主成分分析法对其进行定量分析，并通过主成分分析找出影响城市竞争力的关键因子，对城市发展定位进行分析，得出江西11地市的竞争力排行情况，发现：南昌市和赣州市的竞争力明显强于其他城市，具有一定的虹吸优势；其他城市竞争力相对分散，总体水平不稳定，实力相对较弱。针对城市内部合作意愿较弱、产业发展水平不均衡等问题，提出了加强城市基础设施建设、完善健全社会保障服务、打造城市群发展网络等对策和建议，对推动江西省域经济高质量发展具有一定意义。
In this paper, the index system of urban development competitiveness of Jiangxi Province is con-structed by using the data of the city Yearbook of Jiangxi Province in 2022, and the principal component analysis is used for quantitative analysis. Through the principal component analysis, the key factors affecting urban competitiveness are identified, and the city development positioning is analyzed. The competitiveness ranking of 11 cities in Jiangxi Province is obtained. Nanchang and Ganzhou is obviously stronger than other cities, and they have certain siphon advantages. The competitiveness of other cities is relatively scattered, the overall level is unstable, and the strength is weak. In view of the problems such as weak willingness to cooperate within cities and unbalanced level of industrial development, countermeasures and suggestions were put forward to strengthen the construction of urban infrastructure, improve and perfect social security services, and build the development network of urban agglomerations, which have certain significance for promoting the high-quality development of Jiangxi provincial economy.
