孟中印缅经济走廊中国境内四省(市、区)经济空间演化分析

Study on the Economic Spatial Evolution of the Four Provinces and Cities in the BCIM Economic Corridor

将空间依赖(Dependence)引入密度(Density)、距离(Distance)、分割(Division)的“3D”框架,形成“4D”分析结构。运用主成分分析和空间自相关方法探讨我国参与孟中印缅经济走廊建设的西南四省区市(云南、广西、四川、重庆)的经济地理空间演化特点。研究发现:西南四省区市的经济地理空间3D类型呈现出以重庆、成都、昆明、南宁为中心向外围逐渐下降的演化特征,形成以成渝城市群、滇中城市群、广西北部湾城市群三大中心“开花扩散”,连接成片的区域经济空间发展态势;经济地理格局为非均衡状态,空间分布类型稳定,空间依赖性显著,中心城市和城市群对周边偏远山区的辐射带动作用有待进一步提升;应根据各地区不同的3D空间类型,采取不同的发展措施。由此提出优化四省区市经济地理空间格局的相关建议,以推动西南区域经济的联动发展,推进一体化程度不断提高,带动孟中印缅经济走廊国家和地区的经济进一步发展。

This paper introduces spatial Dependence into the"3D"framework of Density,Distance and Division to form a"4D"analysis structure.Using principal component analysis and spatial autocorrelation method,this paper discusses the characteristics of economic geographic space evolution of four provinces and cities in southwest China(Yunnan,Guangxi,Sichuan and Chongqing)participating in the construction of Bangladesh-China-India-Myanmar Economic Corridor.The study finds that the economic geospatial 3D type of the four provinces and cities shows an evolutionary characteristic of gradual decline from Chongqing,Chengdu,Kunming and Nanning to the periphery,forming the three major city clusters of Chengdu-Chongqing,central Yunnan and Guangxi Beibu Bay.It also shows a trend of spreading on the periphery of the three city clusters.The economic geographical pattern is unbalanced,the spatial distribution type is stable,and the spatial dependence is significant.The city cluster's role as a facilitator in the development of the surrounding remote mountainous areas needs to be further improved.It is suggested that different development measures should be adopted according to the different types of 3D space in each region.Therefore,some suggestions are put forward to optimize the economic geospatial pattern of the four provinces and cities in order to promote the joint development and integration of economy in the southwest China and further improve economic development of the countries and regions of the Bangladesh-China-India-Myanmar Economic Corridor.
