摘要 基于城市群城市间创新联系和创新差异水平的改进引力模型,运用社会网络分析方法探究了2006—2016年长江中游城市群协同创新空间关联网络结构及其时空演变趋势。研究发现:研究期内长江中游城市群城市间协同创新水平整体逐渐提升,但强寡弱多的非均衡格局改变并不显著;空间上形成了以武汉、长沙为中心辐射邻近地区的协同创新高值区,环鄱阳湖城市群相对落后;长江中游城市群协同创新空间关联网络整体密度和效率提升较快,而三大子城市群城市间协同创新发展相对滞后;网络多中心在发育,逐渐由最初的双核主导发展为“3+5”多核心格局;随着创新内外环境的变化,网络内部四个凝聚子群不断重构,结构和功能更加复杂化和层次化。

Abstract:In the technological innovation activities of the new era when numerous information and networking of innovation are increasingly important, collaborative innovation among regions is gradually becoming an effective way to integrate innovation elements and improve innovation efficiency, which can be greatly beneficial to the strategy of innovation-driven development. Based on the modified gravity model where innovation connection and innovation difference level between cities are both considered, this paper measures the degree of collaborative innovation between two cities of urban agglomeration in the middle reaches of the Yangtze River and uses the method of social network analysis to go into the spatial correlation network structure of collaborative innovation of urban agglomeration in the middle reaches of the Yangtze River and its evolution from 2006 to 2016. The conclusions below are founded: During the study period from 2006 to 2016, the degree of collaborative innovation between city and city of urban agglomeration in the middle reaches of the Yangtze River gradually improved, but the change of disequilibrium was not significant. From the space perspective, an area with high- degree of collaborative innovation has formed with Wuhan and Changsha being the innovation center to radiate the neighboring cities and areas, and the urban agglomeration around Poyang Lake was relatively backward. The overall density and efficiency of spatial correlation network of collaborative innovation of urban agglomeration in the middle reaches of the Yangtze River improved rapidly, while the development of collaborative innovation among the three sub- urban agglomerations lagged behind.
