对外直接投资、创新能力提升与国有经济比重——基于我国省际面板数据的研究

Outward Foreign Direct Investment,Improvement of Innovation Capability and the Weight of State-owned Economy:a Study based on Panel Data of Chinese Provinces

在中国对外直接投资规模迅速扩大的背景下,对外投资与企业创新能力间的关系近年来逐步引起研究者关注。该文使用2004-2012年各省面板数据进行了回归,并就我国对外直接投资与创新能力提升间的关系,以及国有经济比重对两者关系的影响进行了研究。研究发现,对外直接投资产生的研发资本溢出对我国的激进式创新和渐进式创新均具有正向促进作用。此外,在国有经济比重较为显著的省份,研发资本溢出带来的创新能力提升受到了一定程度的抑制。分地区进行的回归结果显示,东部地区的OFDI对渐进式创新能力和激进式创新能力的提升效应更符合模型的预测。

In recent years, the scale of domestic companies＇ OFDI （Outward Foreign Direct Investment） activities is growing at a rapid speed. Under this background, the relationship between OFDI and corporations＇ innovation capability has attracted many researchers＇ attention. In this article, based panel data of Chinese province from 2004 to 2012, we conducted a statistical study to reveal the relationship between corporations＇ OFDI activities and improvement of their innovation capability, and the influence that the weight of state-owned economy may have in this relationship. The result shows that the spillover of research capital through OFDI activity has a positive influence to both corporations＇ radical innovation capability and incremental innovation capability. Besides, in provinces with a significant weight of state-owned economy, such improvement is limited to a certain extent. The result of a further regression by eastern, western and central region shows that the model＇s forecast fit the reality of improvement among the eastern region the most.
