摘　　要：区域一体化是减少市场分割,实现区域协同发展的重要阶段,以长株潭一体化为例,选用2000—2013年区县尺度的人均GDP数据,探讨长株潭一体化经济增长格局,发现长株潭一体化经济增长的空间格局是由中心到外围,具体按照"长沙市区→长沙县(市)→株洲、湘潭市区"依次增长;进一步从政府行为变迁的视角,分析长株潭一体化经济增长由中心到外围依次推进的原因,认为地方政府的政策倾向从竞争到竞合,经济开发区的兴建由长沙市区向外围拓展,以及道路基础设施的建设目标由地区内部发展到政区间协同发展,是促进一体化经济由中心到外围发展的三个核心动力。In the process of regional development, regional integration is a highly important stage as it could weaken market segmentation and strengthen economic integration. It is well known that regional integration could greatly promote joint development among different administrative districts. However, a number of empirical studies demonstrated that the degree of economic convergence and the trajectory of economic growth are significantly diverse in different integrated areas. Therefore, this paper attempts to measure economic growth in integrated area, we choose Chang-Zhu-Tan integrated area which is quite typical in studying regional integration, by focusing on the spatial pattern of regional integration. Firstly, in order to measure spatial pattern of regional development in Chang- Zhu- Tan area, we adopt Gaussian Kernel density analytical method by using per capital GDP data in county level from 2000 to 2013. Our results present a center-periphery pattern for economic growth, and its specific pattern is ＂downtown of Changsha→suburbs of Changsha→downtowns of Xiangtan and Zhuzhou＂ in sequence. Secondly, we use index of ＂mean of per capital GDP ratio between different county＂ to analyze disparities among every cities, and demonstrate the veracity of our finding. Finally, after analyzing the transformation of local governments, we find that center- periphery pattern of regional integration is derived by three factors： government policies in urban level have changed their inclinations from competition to cooperation, trend on building economic development zone have changed from center to periphery, and objectives of infrastructure building have transformed from promoting internal development to promoting coordinated development.
