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.
