综合运用主成分分析法、区位商分析法、经济重心分析法分别对川渝城市群的城市发展水平、发展联系、空间重心演变路径进行研究,探寻川渝城市群形成和发展的空间变化规律。研究发现,川渝城市群内的城市间经济发展水平差距较大,城市内部各行业的分配存在差距,但各城市的辐射能力都比较强,而各指标重心变化趋势整体表现为东西差距和南北差距逐渐变小。并有针对性地提出川渝城市群可持续发展的政策建议。
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.
