Study On The Differences Of Innovation Capability And Its Influencing Factors Among Urban Agglomerations

At present,China's economy has become “New Normal” characterized by steady growth,structural adjustment and power conversion.It is urgent to achieve the transformation of economic growth from extensive to intensive growth,industrial production from "Made in China" to "China's invention",the mode of economic development from catching up to innovation.To achieve these changes,innovation must be the first driving force for development and we must continue to promote the improvement of China's innovation capabilities.With the characteristics of compact space,close economic relations and strong cultural identity,the urban agglomeration has gradually caught the attention of academia and the government.Taking urban agglomeration as the main body,promoting economic and social construction,and promoting regional coordinated development have become the hotspots of the whole society.This paper takes China's major urban agglomerations as the research object.Firstly,the Dagum Gini coefficient method is used to measure and decompose the gap of urban agglomeration innovation ability,and the spatial correlation of urban agglomeration innovation ability is analyzed by ESDA analysis method,hoping to know the gaps and changes in the innovation capabilities of various urban agglomerations in China.Secondly,on the basis of extensive reading of the literature,the urban agglomeration innovation ability system is established,and the factors affecting the innovation ability of the urban agglomeration are analyzed from the theoretical perspective,including the investment of innovative personnel,innovative capital investment,government support,higher education,foreign direct investment,and environmental quality.Meanwhile,put forward research hypotheses on the effect of various influencing factors.Finally,the spatial measurement method is used to empirically test the factors affecting the innovation ability of urban agglomerations.The results of this paper show that: First,the overall gap of innovation ability of urban agglomerations in China is relatively large.The leading edge of innovation ability of Pearl River Delta,Yangtze River Delta,Beijing-Tianjin-Hebei urban agglomeration is more obvious.The innovation ability of Chengyu,Guanzhong Plain and Zhongyuan urban agglomerations is in the middle.The Yangtze River Middle,Hachang,Beibuwan urban agglomerations have relatively weak innovation capabilities.Second,the differences in urban innovation capacity among different urban agglomerations are large.For Beijing-Tianjin-Hebei,Guanzhong Plain,Chengyu,Yangtze River Middle,and the Guanzhong Plain urban agglomerations,the regional gap in urban innovation capacity within urban agglomerations is relatively large.The regional disparity in urban innovation capacity in Hachang,Pearl River Delta,Yangtze River Delta,and Zhongyuan urban agglomerations is relatively small.Third,the innovation capabilities of cities within urban agglomerations have significant spatial homogeneity characteristics.Fourth,the input of innovative personnel,investment in innovation,government support will promote the improvement of the innovation ability of urban agglomerations,but the role of government support for the improvement of innovation capacity is relatively small.FDI may have a diametrically opposite impact on the ability to innovate in cities at different stages of development.Physically,it is characterized by “U” type.Fifth,for the Pearl River Delta and the Yangtze River Delta urban agglomeration with strong innovation ability,the enterprise's innovative capital investment is the main driving force for the improvement of its innovation ability.For the Hachang and the Beibuwan urban agglomeration with weaker innovation,its innovative ability is still driven by FDI.
