Analysis of Regional Economic Development Level in Sichuan Province based on Grey Clustering Model

Abstract

Objective: Conduct a study on the spatial economic connections of the urban agglomerations in Sichuan Province region, analyze its current situation, characteristics, and problems, and provide a basis for strengthening the spatial economic connections of the urban agglomerations in Sichuan Province region. Methods: Comprehensively apply methods such as literature review, theoretical analysis, qualitative analysis, and quantitative calculation. Measure and analyze the intensity and direction of the spatial economic connections of the Chengdu - Chongqing urban agglomeration by improving the gravity model, economic affiliation index, and other means. Conclusions: 1) The overall spatial economic connections of the urban agglomerations in Sichuan Province region are loose. 2) The influence of Chengdu extends in a radial pattern towards southern Sichuan and northeastern Sichuan. 3) The economic connection directions of the urban agglomerations in Sichuan Province region are obviously directional. 4) The main economic connection direction of Chengdu is the Chengdu - Deyang - Mianyang - Leshan development axis.
