Economic Di Stance?International Spillout And Technique Progress

This paper mainly measures the relationship between international R&D spillovers based on trade and domestic technological progress.the method of "Economic Distance" and "Geographical Distance" was used to measure the international R&D spillover weight,which was the core innovation of this paper.Meanwhile,add the domestic R&D capital variable and human capital variable in the empirical model to measure the effect of common on total factor productivity and its decomposition Index together,which was the empirical core of this paper.In theory,starting from the trade-related international R&D spillover effects,it is suggested that not only direct R&D spillovers can be produced between countries through direct trade,but also possible to achieve indirect R&D spillovers through trade rounds with intermediate countries.Thereafter,this paper puts forward the concrete forming mechanism of"trade round",and combine "economic distance" and "geographical distance" between countries as a measure of international R&D overflow basis.In empirical,this article interception from 2000 to 2012 panel data from China's eastern three major regions in the election of seven representative provinces.Taking into account the G-7 countries(R&D investment in OECD countries has been maintained at more than 77%)and the provinces of the import and export trade data to measure international trade relations.Firstly,Based on Coe and Helpman's classical model,this paper extends the empirical model and adds the human capital variable.Therewith,it was found that the combination of "economic distance" and"geographical distance" can also reflect the true international R&D spillover capital in this paper with using four kinds of methods to measure international R&D spill capital.Finally,an empirical study the impact on domestic R&D capital based on panel data regression model,R&D spillovers of capital and human capital on TFP about their decomposition Index,which was found that domestic R&D capital and international R&D spill capital can promote the growth of total factor productivity.While the impact of human capital on total factor productivity is negative,due to the current outflow of high-tech talent,the high saturation of college students,as well as the unreasonable allocation of human capital.
