基于PCA-ESDA的成渝城市群经济发展空间差异研究

摘要

基于统计年鉴面板数据,运用主成分分析法(PCA)和探索空间数据法(ESDA)对成渝城市群各城市经济发展水平进行综合测度,并在空间上对其集聚和异质性进行分析。研究提取出经济实力、经济品质和经济结构三项主成分,评价得分和空间相关性的综合研究表明:经济实力上,全局与局部相关性均不显著,成渝两城市极化明显,缺乏区域副中心城市,城市群发展能级不足;经济品质上,空间相关性以“二元集聚”的异质性显著呈现, 重庆地区辐射带动效应强于四川地区;经济结构上,“川东——渝西”产业板块日益显现,但存在产业同质化现象。研究综合面板数据和空间地理数据,客观揭示了成渝城市群的经济发展水平差异,并提出相应的发展对策,以期对成渝区域协调发展提供理论和实践参考。

Abstract

At present, the development of Chengdu-Chongqing urban agglomeration has officially risen to a national strategy. This paper builds comprehensive indicators based on the panel data of the three-phase statistical yearbooks of 2007, 2012 and 2017, using principal components. The analysis method organically combines the results of mathematical statistics and spatial correlation analysis, and focuses on spatial heterogeneity to explore the spatial differentiation of the economic development of the Chengdu-Chongqing urban agglomeration. The study extracted three principal components of economic strength, economic quality, and economic structure. The research also appears to be particularly important. Based on the background of implementing the “Chengyu Urban Agglomeration Development Plan” and the promotion of the “Chengyu Region Two-City Economic Circle Construction”, this paper builds comprehensive indicators based on the panel data of the three-phase statistical yearbooks of 2007, 2012 and 2017, using principal components.
