The Influence Of Intermediate Goods Import On R&D Investments And Its Mechanism

Under the background of the adjustment of domestic industrial structure,the optimization and upgrading of manufacturing industry,the international "high and low squeeze" and the intensification of trade friction,encouraging enterprises to innovate and expand imports are considered as the two major policy forces to achieve the coordinated development of economy at Therefore,this paper intends to take the import of intermediate products as the research object,on the basis of summarizing the domestic and foreign research results,focusing on the impact of intermediate import on China's manufacturing industry innovation mechanism.Taking the import of intermediate products as the breakthrough point,it is of great significance to study the impact of expanding import on enterprise innovation in order to find an effective way to China's innovation and promote the current series of "export promotion" policies.On the basis of the existing literature,this paper first describes the current situation of innovation investment in China's manufacturing industry,and makes a brief analysis of the status of China's intermediate import from the aspects of scale and structure.Then systematically sort out and conclude the approaches and mechanisms of the import of intermediate products affecting the R&D investment of manufacturing enterprises,specifically analyze the theoretical mechanism from the perspectives of cost reduction,quality demonstration and foreign R&D spillover,and put forward corresponding research hypotheses.After that,the data of Uncomtrade database and China's industrial enterprise database from 2000 to 2015 were used to form panel data of the manufacturing industry by selecting variables such as the import scale and quality of intermediate products,R&D investment in the manufacturing industry and operating cost for empirical analysis.On this basis,the relevant research was expanded by dividing different technology types and different import regions,and endogeneity and robustness tests were carried out to improve the reliability of the conclusions of this paper.Then,two indicators of enterprise characteristics,enterprise scale and enterprise performance,were selected for further analysis by threshold regression.Finally,the author puts forward relevant Suggestions based on the current situation and empirical analysis.The empirical results show that:(1)the import of intermediate products significantly promotes the R&D investment of Chinese manufacturing enterprises,andthe promotion effect is different between industries and regions.Intermediate products imported from developed countries can induce enterprises to develop R & D activities.(2)Import of intermediate products increases R&D investment by reducing the operating costs of enterprises;competitive and imitative effects of high-quality import of intermediate products will encourage enterprises to carry out R&D innovation;at the same time,foreign R&D spillovers also promote the technological upgrading of enterprises through the transmission of supply chains.Among them,foreign R&D spillovers play the most significant role in upgrading the R&D level of manufacturing industry,followed by cost-saving effect and quality demonstration effect is relatively weak.(3)In addition,enterprises with scale advantages and performance advantages can not only have the advantage to carry out R&D activities,but also make full use of intermediate import activities to further enhance their R&D investment level.This paper clarifies the effects and ways of intermediate imports on R&D of manufacturing enterprises,enriches and expands the research perspective of enterprise innovation,and helps the government to adopt targeted policy measures to promote the landing of import trade projects.
