Research On The Influence Of Social Capital On The Innovation And Economic Growth Of Chinese Urban Agglomeration

After China first proposed to use urban agglomerations as the main form of urbanization,several urban agglomerations were planned.At present,the main position of urban agglomerations in the process of urbanization in China has become clear,and it has begun to play its leading role in promoting regional economic development.So it is necessary and is important to study economic growth of urban agglomeration.In addition,apart from material capital,labor,human capital and technology mentioned in the classic economic growth theory,the academic community has widely recognized social capital affecting economic growth,the impact of social capital on economic growth has become a key area of economic growth theory research.Therefore,constructing the social capital index system from the perspective of urban agglomeration,and obtaining the comprehensive evaluation index of social capital,and discussing its impact on the economic growth of urban agglomeration is the focus of this paper.Firstly,by exploring the connotation of social capital of urban agglomeration,this paper constructs the social capital index system,and uses principal component analysis to obtain comprehensive evaluation index and comprehensive score of urban capital social capital level.Then,based on the Romer model,social capital is taken as an endogenous variable,and at the same time,it is put into the knowledge production function and the output function,so the theoretical model of social capital affecting the economic growth of urban agglomeration is constructed.Finally,using the relevant data of the five major urban agglomerations in the past 15 years from 2002 to 2016,the model was tested empirically.The comprehensive score of social capital level of urban agglomerations shows that the social capital level of urban agglomerations has increased steadily with time,and the gap between urban agglomerations has narrowed.In addition,the empirical results of the model show that social capital has a significant positive impact on China’s urban agglomeration innovation and economic growth.Therefore,cultivating urban agglomeration social capital and building an urban agglomeration innovation system is conducive to the further development of urban agglomeration.
