利用区位熵、耦合协调模型、趋势面分析、引力模型等对长江经济带城市功能与区域创新耦合协调度进行了测算,并对其空间联系进行了分析。得到了以下结论:2004~2014年,各个城市单元整体的耦合协调度均有一定程度的提升,逐渐形成三大连绵较高协调集聚区,长江经济带总体耦合协调度呈现出“下游高-中上游低”的空间趋势;空间联系的最大引力线联结格局比较稳定,长三角城市群是耦合协调发展的重要基地和优势集聚区;长江下游地区空间联系的网络密度与网络结构的复杂程度远高于长江中上游地区,并且逐渐形成由以长三角为核心城市圈,牵引长江中上游城市多极化发展的网络结构。
The coordination of urban function and regional innovation in the Yangtze River economic belt was estimated by using the location entropy, the coupled coordination model, the trend surface analysis and the gravity model, and the spatial connection was analyzed. The following conclusions are drawn: From 2004 to 2014, the overall coordination degree of urban units in each city has been improved to some extent, and gradually formed three large and continually high coordination gathering areas. The overall coupling and coordination degree of the Yangtze River economic belt shows “ Middle and upper reaches of the lower reaches of the Yangtze River. ”The spatial structure of the maximum gravitation line in space connection is relatively stable. The urban agglomeration in the Yangtze River Delta is an important base for co-ordination and coordinated development and a dominant agglomeration area. The spatial density of network connectivity in the lower reaches of the Yangtze River and the complexity of the network structure Far higher than the middle and upper reaches of the Yangtze River, and gradually formed a network structure that takes the Yangtze River Delta as the core urban circle and draws on the multi-polarization development of the cities in the middle and upper reaches of the Yangtze River.
