2008年后,我国海外投资存量大幅增加,获得东道国技术转移以提升我国科技水平是一个重要原因。本文以2004—2011年全球7个主要经济体的81个国家32个①方面的数据为样本,利用修正过的反向知识溢出模型,计算了不同地区可以获得的知识转移量;然后以门槛模型分析了对外直接投资(OFDI)和外商直接投资(FDI)在促进我国科技进步时的相互作用,针对不同经济体的具体情况进行了实证分析,最后给出具有针对性的政策建议。
The stock of outward foreign direct investment(OFDI) from China surged after 2008. One main reason for this phenom- enon is to obtain knowledge transfer from the host countries in order to improve the technology level of China. Using 32 aspects of 81 countries from 7 economic entities in the period from 2004 to 2011, and based on the corrected reverse knowledge spillover model, this paper first calculates the amount of knowledge transfer from each economic entity, and then analyzes the relationship between OFDI and FDI in promoting the technological progress in China based on the threshold model. What' s more, specific empirical analysis for each economy is made based on 2SLS model. Finally, specific policy proposals are given.
