我国对外直接投资的逆向技术外溢效应研究

本文选取我国对外直接投资比较集中且技术水平比较发达的九个国家(地区),利用我国和九国(地区)对外直接投资与技术创新的投入产出数据,测算我国的全要素生产率、母国和东道国的研发资本存量,实证分析了我国直接投资到这些国家(地区)所产生的逆向技术外溢程度。研究结果表明,我国通过对外直接投资渠道获得的国外研发资本存量能给母国带来正的技术外溢效应,只是由于我国对外直接投资相对吸引外资而言发展缓慢,因而其技术外溢效应相对较低。

A Research on the Technological Spillovers Effects of China’s Outward Direct Investment

In an opening economy,how China makes use of various technological spillovers channels to get advanced technology abroad and improves its digestion,absorption,and re-innovation capability already becomes an important issue for building an innovation-oriented country.This paper analyzes the reverse technological spillover mechanism of home country through Outward Direct Investment.It selects nine countries(regions) which are more concentrated of China’ s ODI and have advanced technology,and analyzes the reverse technology spillover effect of China’s ODI by estimating China’s total factor productivity and the home and host countries' R&D capital stock on the basis of relevant data of China and nine countries(regions).The empirical results show that there are positive technological spillovers effects of foreign R&D capital stocks through China’s ODI in the home country.The technological spillovers effects are rela-tively low since the development of Chinas’ ODI is slower than FDI.
