| China's economic development has entered a new normal,manufacturing as an important part of economic development,the first challenge is how to achieve the overall industrial transformation and upgrading.Innovation is one of the source of the development of China's manufacturing industry is an important source of manufacturing transformation,and industrial agglomeration in a sense to stimulate the ability to enhance innovation,and industrial agglomeration through innovation to promote industrial transformation and upgrading into a manufacturing transformation Upgrade a path.In this paper,combined with the new economic geography,global value chain theory,intermediary effect analysis and other methods,first of all on the industrial agglomeration,innovation and industrial upgrading of the relevant theory and the literature between the literature were sorted out and summarized,followed by Krugamn concentration Index of the Chinese manufacturing industry 21 sub-industry concentration was calculated,and then the environment-friendly,labor productivity,industrial structure of the three elements of the use of principal component analysis into a comprehensive transformation and upgrading of manufacturing indicators,The concentration of manufacturing industry in China was measured.The 21 sub-sectors will be divided into labor-intensive,capital-intensive and technology-intensive industries according to the different factors of the factors,respectively,compared the three industries of industrial agglomeration index and industrial transformation and upgrading indicators.This paper explains the theory of industrial agglomeration by promoting the innovation level and promoting the industrial transformation and upgrading,and puts forward seven hypotheses.Finally,the mediating effect of innovation in the whole industry of manufacturing industry and three kinds of different factor-intensive industries is measured by the analysis method of intermediary effect,and the hypothesis is tested. |
