The Research On Effects Of R&D Input And Trade Openness On High-tech Industry Innovation Capacity

Technical innovation is the internal motivation of economic growth.There are two kind sources of technology.One is initiative called “technical innovation”,which is the result of independent research and development;the other is passive called “technological diffusion”,such as learning by doing and technology spillover.This article studies the effects of these two kind sources on high-tech industry innovation capacity in our country,referencing and using the theories of “technical innovation”,“innovation-driven growth” and the model of “trade spillover”.Based on the modified Cobb-Douglas production function,it builds a static panel model and a dynamic panel model about input-output for high-tech industry,uses the panel data of our whole country and its three regions,and the whole high-tech industry from 1998 to 2015,then makes a comparison between them through panel unit root test,cointegration test,Granger causality test and panel regression including static LS and dynamic GMM.The results demonstrate the long-term equilibrium stable relationship of R&D input,trade openness and high-tech industry innovation capacity.They both have significant positive promoting effects on technical innovation and it mainly relies on independent research and development.According to the results,eastern R&D capital input and trade openness have more positive effects on technical innovation than central and western regions,but R&D human resource input has more effects in central and western regions.Therefore,China should pay more attention to independent innovation.All regions should increase R&D input actively to push forward technical innovation independently and take part in the construction of “One Belt One Road”.They should make a good use of their comparative advantages and strengthen their interaction and cooperation with each other.Eastern region can lead the developments of central and western regions,then improving the level of open economy in China.In addition,strengthening the economic cooperation and technical exchange with other countries and expanding trade openness are beneficial to promote the technical innovation of high-tech industry and achieve the strategic goal of win-win cooperation.
