外商直接投资和对外直接投资是国际R&D溢出的两条重要渠道。本文利用我国1985~2008年数据,运用协整理论和误差修正模型,对我国外商直接投资、对外直接投资和技术进步的关系进行了经验分析。结果表明,外商直接投资渠道的国外R&D存量显著提升了我国全要素生产率,而对外直接投资渠道的国外R&D存量对国内技术进步的促进作用却非常微弱。原因可能包括现阶段我国对外投资规模有限、技术获取型对外投资比例偏小、技术吸收能力偏弱等。
Abstract
Foreign Direct Investment(FDI) and Outward Foreign Direct Investment(OFDI) are two channels of international R&D spillovers. Based on the data during the period of 1985-2008 in China, the relationship among FDI, OFDI, and technological progress in China is estimated by using the cointegration theory and vector error correction model.The empirical results reveal that international R&D through FDI has significantly promoted China's total factor productivity, however international R&D through OFDI has very weak spillovers on TFP. The reason for that is that the scale of OFDI is limited, the proportion of technology sourcing OFDI of China is too small, and China's absorptive capability is too weak.
