分析了长江沿江六大国家战略发展区(即长三角地区、皖江城市带、武汉城市圈、鄱阳湖生态经济区、长株潭城市群、成渝经济区)的发展状况。基于极化区理论,提出了国家战略发展区识别的“自上而下”与“自下而上”相结合的方法,并结合经济发展水平和实力、经济的外向化程度、产业和服务业区位熵的定量分析,初步识别了各战略发展区的功能,即长三角经济区主要承担参与国际竞争、创新和门户功能,皖江城市带主要承担区域服务带动和创新功能,鄱阳湖经济区主要承担生态保育和区域带动功能,武汉城市圈主要承担中部带动和创新功能,长株潭城市群主要承担区域服务和带动功能,成渝经济区主要承担西部生态保育、西部带动功能。
Analyzes the development of strategic development zones in the six major countries along the Yangtze River (ie, the Yangtze River Delta, Wanjiang City Zone, Wuhan City Circle, Poyang Lake Ecological Economic Zone, Chang-Zhu-Tan City Cluster, Chengdu-Chongqing Economic Zone). Based on the polarization zone theory, this paper proposes a combination of “top-down” and “bottom-up” identification of the national strategic development zone. Combined with the level of economic development and the degree of outward- The quantitative analysis of the location entropy of industries and service industries initially identified the functions of the strategic development zones, namely, the Yangtze River Delta Economic Zone mainly undertakes the functions of international competition, innovation and portals. The urban belt of Wanjiang City mainly undertakes the service and innovation function of regional services. The lake economic zone mainly undertakes the functions of ecological conservation and regional driving. The urban circle of Wuhan mainly undertakes the driving and innovation functions of the central region. The urban agglomeration of Chang-Zhu-Tan mainly undertakes the service and driving functions of the region. The Chengdu-Chongqing Economic Zone mainly undertakes the functions of ecological preservation in the west and driving functions in the west.
