THE SPACIAL VARIATION OF THE FORMATION AND DEVELOPMENT OF URBAN AGGLOMERATION IN SICHUAN- CHONGQING
综合运用主成分分析、区位商和经济引力分析，研究成渝城市群各城市的发展差距、产业辐射能力及东西、南北方向经济引力差异的演变，并提出发展建议。
The paper comprehensively uses Principal Component analysis,Location Quotient analysis,Economic Gravity analysis to research the urban development,development relations and evolution path of economic gravity in Sichuan-Chongqing Urban Agglomeration,and explore the evolution of spatial variation of the formation and development of Sichuan-Chongqing Urban Agglomeration.We find that: there's a large gap among those cities of Sichuan-Chongqing Urban Agglomeration;the large range of internal location quotient of each city shows that there's gap among every industry in inner city,but radiating capacity of each city is quite strong,and the gravity evolution of each index tells that the gap between the west-east and north-south is getting gradually narrowed.At last,it puts forward some suggestions of the sustained development of Sichuan-Chongqing Urban Agglomeration.
