The Measurement on Economic Connection in Changzhutan Urban Agglomeration
通过构建综合竞争力指数、引力模型和城市流强度模型，分析了长株潭城市群内部城市间的经济联系，发现整体竞争力不强、对外服务功能弱、辐射能力有待提升，且各城市与核心三角联系紧密但彼此间联系较弱。
This research analyses the economic connection between different cities in Changzhutan urban agglomeration by establishing index of overall competitiveness and the calculation of gravity model and the intensity of urban flow model. It concludes that the overall competitiveness of changsha- zhuzhou- xiangtan urban agglomeration is not strong,outgoing service function is weak and urban agglomeration and radiation ability needs to improve. In addition, the degree of connection between different cities in changsha as the center to the periphery, every city has a strong connection withgold trianglewhich consist of Changsha/zhuzhou/Xiangtan. However, the connection between them is weak, and the sub-center is not prominent, the difference of the spatial framework of economic connection is similar.
