OFDI逆向技术溢出对国内技术创新影响的实证分析——基于自主创新和模仿创新视角

Empirical Analysis on the impact of OFDI reverse technology spillover on domestic technological innovation ——From the perspective of independent innovation and imitation innovation

摘要:

通过梳理以往文献并采集我国2008-2017年十年间30个省市的面板数据，运用固定效应模型对OFDI逆向技术溢出对国内不同地区、不同类型创新模式的异质性影响进行实证分析。结果表明：无论从全国整体还是从分地区来看，OFDI均存在显著的逆向技术溢出效应；国内研发投入对技术创新的影响大于OFDI，且其仅对东部地区技术创新有显著影响，对中西部地区影响不大；OFDI对自主创新的促进作用大于模仿创新，说明OFDI的自主创新外溢效果更强；另外，研究还发现目前我国的研发人员力量相对薄弱，人力资本结构不合理，高端科研人员数量不足，严重制约了直接对外投资的吸收能力

Abstract:

By combing past literature and collecting panel data from 30 provinces and cities in China during the ten years from 2008 to 2017, a fixed-effects model was used to conduct an empirical analysis of the heterogeneous impact of OFDI reverse technology spillovers on different regions and different types of innovation models in China. The results show that: either from the perspective of the national overall or points region OFDI are significant reverse technological overflow effect; domestic r&d investment has a greater impact on technology innovation than OFDI, and it only has a significant impact on technological innovation in the eastern region, and has little impact on the central and western regions; in addition, the research also found that China's r&d personnel are relatively weak, the human capital structure is unreasonable, and the number of high-end researchers is insufficient, which seriously affects the absorption capacity of OFDI.
