Abstract:

With the methods of local Gini coefficient, spatial autoregression, NICH coefficient and panel data model, this study takes the 38 center cities along the Yangtze River Economic Belt as spatial observing units to discuss the spatio-temporal evolution characteristics and its causes of innovation output, measured by the number of patents authorization and other related data. The result indicates that from 2000 to 2013, the overall innovation output in the center cities along the Yangtze River Economic Belt is increasing year by year, while the geographic concentration of it presents a fluctuated downward trend. The relative development rate of the Yangtze River Delta area is faster than others. The agglomeration degree of innovation output shows a shape of mirrored “Z” with a fluctuated upward trend. The hot spots regions of innovation output develop into a “monopolar-prominent” spatial pattern in the Yangtze River Delta area from a “dual-central” spatial structure in the Yangtze River Delta area and Chengdu-Chongqing area, and the scope of hot spots regions is extending. Besides, the cold spots regions are concentrated in the middle reaches of the Yangtze River; Technology spillover, government actions, spatial proximity and financial supports can make significantly positive effects on the innovation output in the center cities along the Yangtze River Economic Belt, and the economic foundation can promote the development of innovation output in downstream cities. According to the conclusions, this article also propounds some corresponding suggestions.

Key words: innovation output, the Yangtze River Economic Belt, spatial-temporal evolution
