| Manufacturing is the main body of the real economy,is also the "Ya Cang Shi" of national economic development,the party’s 20 report to promote manufacturing to the direction of intelligent,green,high-end,and with the progress of science and technology,the digital economy quietly rise,digital economy and real economy integration degree is becoming more and more deep,promote the development of manufacturing,high quality,digital economy.As a big manufacturing province,Jiangsu province manufacturing output is always located in the top,relying on the economic foundation,geographical environment advantage,the digital economy scale also in the national leading level,so this paper choose Jiangsu province as the research object,explore the mechanism of digital economy for manufacturing development,summarize and grasp the influence of digital economy,in order to promote the healthy development of manufacturing industry in Jiangsu province.This paper first summarizes the existing literature at home and abroad,and summarizes the digital economy and manufacturing high quality development measurement,the digital economy,and manufacturing high quality development influence mechanism,from the development of digital economy,the theory,from innovation development,coordinated development,green development,open development,sharing development elaborated the digital economy influence manufacturing high quality development mechanism,and put forward the research hypothesis of this paper.Then,the development status of digital economy and high-quality development of manufacturing industry in Jiangsu Province are analyzed,and the development characteristics and existing problems of digital economy and manufacturing industry in Jiangsu Province are summarized.After building index system of digital economy development level and manufacturing high quality development level,using the entropy method of digital economy development index De,manufacturing high quality development index Hqd,and the two to establish empirical measurement model,combined with control variables in basic regression analysis,intermediary effect analysis,quantile regression analysis,threshold regression analysis,spatial effect analysis and regional heterogeneity analysis,empirical conclusion and through the robustness test.Empirical research conclusion shows that digital economy can directly provide new momentum for the high-quality development of manufacturing industry in Jiangsu Province,The impact of digital economy on the high-quality development of the manufacturing industry in Jiangsu province has a threshold value,The digital economy level above the threshold level promotes the manufacturing industry significantly more than the digital economy level below the threshold value,Digital economy can indirectly influence the development of the manufacturing industry in Jiangsu province through the intermediary variables,On the one hand,the digital economy can promote the high-quality development of the manufacturing industry by promoting the upgrading of the industrial structure,On the other hand,the digital economy can affect the high-quality development of the manufacturing industry by affecting the level of human capital,However,the influence path through the human capital level is only effective in the southern Jiangsu province and the central Jiangsu region;The development of digital economy in various prefecture-level cities in Jiangsu Province has a negative spatial spillover effect on the high-quality development of manufacturing industry in adjacent areas.Finally,according to the empirical conclusion,the policy suggestions are put forward from the two aspects of improving the development ecology of digital economy and improving the manufacturing innovation platform system. |
