国际R&D溢出、国内R&D和真实经济增长——基于技术扩散模型的一个实证

目前已有大量的关于FDI和加工贸易国际R&D溢出的研究,本文改进了巴罗具有扩大的产品种类的技术扩散模型,将FDI国际R&D溢出、加工贸易国际R&D溢出、国内R&D三者共同作为技术进步的来源和经济增长的解释变量,通过对我国1983～2006年经济数据的实证分析表明,人力资本和国内R&D对经济增长的贡献具统计学意义上的显著性,且存在长期均衡关系;但没有足够的证据表明FDI和加工贸易对经济增长的显著正向外溢效应。

International R&D Spillover,Domestic R&D and Real Economic Growth in China:An Empirical Study on the Mode of Technical Diffusion

There are a great deal of studies on international R&D spillover in FDI and processing trade. This paper improved Barrow's technique diffusion mode which expanded the range of products. It made three factors, international R&D spillover in FDI, processing trade of international R&D spillover, and domestic R&D, as the source of technical progress and the explanatory variables of gorwth to analyze the data during 1983～2006 empirically. The conclude showed that the contribution of the human capital and domestic R&D to economic growth has the significant effect statistically, and there was a equilibrium relationship between them in a long-run. However, there was no enough evidence to prove that FDI and processing trade had significant and positive spillover effect on economic growth.
