四川省各地级市区域经济发展水平研究

Research on Regional Economic Development Level of Prefecture-Level Cities in Sichuan Province

摘要: 本文选取2021年四川省13个地级市的11项经济发展指标，使用主成分分析、聚类分析方法针对四川省区域经济发展水平和不均衡发展问题，研究以下问题：1) 区域经济发展水平；2) 区域经济发展的差异。结果表明：1) 四川省各地级市第一主成分得分从高到低分别是：成都(3.249)，绵阳(0.124)，其他均为负值，表明这几个城市经济总量水平较高，其他城市城市经济总量水平较低；第二主成分从高到低的分别是：南充(2.238)，达州(1.801)，绵阳(0.225)，其他均小于0.2，表明前三个城市人民生活水平较高；第三主成分从高到低的分别是：德阳(1.441)，绵阳(1.27)，宜宾(1.187)，乐山(0.979)，自贡(0.276)，其他城市均为负值，表明前五个城市对外贸易经济、农林经济实力较好；2) 从经济发展水平上看，成都为第一梯队，南充、达州、遂宁、眉山、广安、泸州、内江、绵阳、宜宾、德阳、自贡、乐山为第二梯队，表明四川省各区域经济发展水平差异较大，发展模式与产业结构差异较大，城市经济发展水平存在着一定差异，不平衡现象仍较显著，在此基础上提出相应发展建议，以期为四川省经济协调发展、城镇建设提供相关理论依据。

Abstract: In this paper, 11 economic development indicators of 13 prefecture-level cities in Sichuan Province in 2021 are selected, and the problem of regional economic development level and unbalanced development in Sichuan Province is studied using the principal component analysis and cluster analysis methods. The following problems are studied: 1) regional economic development level; 2) the difference results of regional economic development. The results show that 1) the first principal component scores of prefectural level cities in Sichuan Province are respectively from high to low: Chengdu (3.249) and Mianyang (0.124), and the others are negative, indicating that the economic aggregate level of these cities is high, while that of other cities is low; the second main components from high to low are: Nanchong (2.238), Dazhou (1.801), Mianyang (0.225), and the others are less than 0.2, indicating that the living standards of the first three cities are higher; the third main component from high to low is: Deyang (1.441), Mianyang (1.27), Yibin (1.187), Leshan (0.979), Zigong (0.276), and other cities are negative, indicating that the foreign trade economy and agriculture and forestry economic strength of the top five cities is better; 2) from the perspective of economic development, Chengdu is the first echelon, South Chong, Dazhou, Suining, Meishan, Guangan, Luzhou, Neijiang, Mianyang, Yibin, Deyang, Zigong and Leshan is the second echelon, which indicates that there are great differences in economic development level, development mode and industrial structure among different regions in Sichuan Province, and there are certain differences in urban economic development level, and the imbalance is still significant. On this basis, corresponding development suggestions are put forward to provide relevant theoretical basis for the coordinated economic development of urban construction in Sichuan Province.
