Research On The Impact Of R&D Investment On Industrial Development Of High-end Manufacturing

Under the background of the implementation of "Made in China 2025" strategy and the further escalation of trade frictions between China and the United States,the development of high-end manufacturing industry has become a new engine of economic development,which determines the country's future international competitiveness and division of labor status.China's high-end manufacturing industry has made good achievements in the process of development,but at the same time,there are also some problems to be solved.To solve these problems,to better promote the development of high-end manufacturing industry in China,and to understand the relationship between R&D investment and industrial development is very important.It has important practical significance to promote the transformation and upgrading of China's economic development mode.Firstly,this paper combs the domestic and foreign research status and relevant theoretical basis,reasonably defines the concept of high-end manufacturing industry,analyzes the development status and main problems of high-end manufacturing industry in China,and reveals its causes.Then,taking panel data of high-end manufacturing industry in China from 2007 to 2016 as research samples,using the general fixed-effect panel model and Hansen threshold panel regression component.Analytical method: R&D investment is measured by R&D investment intensity and R&D personnel investment intensity,and industrial development is measured by main business income and industrial agglomeration.The relationship between R&D investment and industrial development in high-end manufacturing industry is empirically analyzed.The threshold effect of R&D investment intensity and R&D personnel investment intensity are tested,and the best R&D investment threshold effect is found out.On this basis,in order to prevent the excessive agglomeration of high-end manufacturing industry and the uneconomical scale of resources,the interaction between R&D investment and industrial development is further tested by taking industrial agglomeration as a threshold variable,and the optimal industrial agglomeration interval is found out,which reveals the internal mechanism of the impact of R&D investment of high-end manufacturing industry on industrial development.The results show that:(1)R&D investment is an important factor in the development of high-end manufacturing industry,and increasing R&D investment can help to improve industrial innovation ability and promote industrial development;(2)R&D investment andR&D personnel investment have synergistic effect on industrial development;(3)R&D investment has a significant double threshold effect on industrial development,while R&D investment has a significant double threshold effect on industrial development.There are three threshold effects in the threshold test of investment intensity of R&D;(4)The Empirical Study on the interaction between R&D investment and industrial development shows that there is the best industrial agglomeration zone in industrial development.When the industrial agglomeration is in the middle zone,the R&D investment intensity and R&D personnel investment intensity have the strongest impact on the development of high-end manufacturing industry;(5)The government has the strongest role in promoting the development of high-end manufacturing industry.Subsidies have little or even negative effects on industrial development,while the role of patent level is not obvious.Foreign investment and industrial profits have obvious promoting effects.In view of the research results,this paper puts forward the following countermeasures and suggestions:(1)encourage and guide enterprises to increase R&D investment and improve technological innovation capability;(2)improve intellectual property system and improve R&D investment support system for technological innovation;(3)strengthen the construction of high-end talents and formulate relevant talent introduction policies to promote the deep integration of industry,University and research;(4)rationally allocate R&D investment and make full use of it.Give full play to the synergistic effect of R&D investment and personnel investment;(5)Establish a coordination mechanism to guide the development of industrial agglomeration and control the level of high-end manufacturing agglomeration;(6)Encourage investment and attract high-quality foreign investment to promote Sino-foreign cooperation and mutual learning R&D.
