Abstract
In order to give full play to the role of international direct investment in promoting the independent innovation of high-tech enterprises,this paper conducts an empirical research on the relationship between international direct investment and in-dependent innovation of high-tech enterprises based on the panel data of the electronic and communication device manufacturing in-dustry from 2010 to 2022.By selecting independent variables,dependent variables,control variables and threshold variables,de-scriptive statistics,regression analysis,robustness test,and endogenesis test are conducted,and the relationship between the de-pendent and independent variables is analyzed.The results reveal that there are obvious differences in the independent innovation of electronic and communication device manufacturing industry,among which,the technology investment reversely inhibits its inde-pendent innovation,while international direct investment,R&D human capital,enterprise scale,National R&D subsidies,market operating conditions and the level of opening to the outside world positively promote its independent innovation.There is a pair of co-integration relationships between the electronic and communication device manufacturing industry and R&D investment,there are two pairs of co-integration relationships with international direct investment,R&D human capital,enterprise scale,technology in-vestment,national R&D subsidies,market operating conditions,and the level of opening to the outside world,and all are signifi-cantly correlated when the level of significance is 1%.International direct investment can positively promote the independent innova-tion of electronic and communication device manufacturing industry,and with the increase of R&D human capital threshold,the promoting effect shows a characteristic of first decreasing and then increasing.Setting the threshold value of R&D human capital to less than 11.364 can better play the role of international direct investment in promoting the independent innovation of electronic and communication device manufacturing industry.Based on the empirical results,it is concluded that in order to further play the role of international direct investment in promoting the independent innovation of high-tech enterprises,it is necessary to start from impro-ving the investment environment,introducing R&D personnel,increasing investment,creating an atmosphere of independentinno-vation,strengthening the opening up of the industry,and carryingout healthy industry competition.关键词
