中国地区间互作、人力资本、技术扩散与技术进步

The Effects of Human Capital,Technology Diffusion and Regional Interaction on Regional Technological Progress in China

本文在新经济增长理论关于技术进步的理论基础上,通过引入反映地区间相互作用的空间外部性因素,从联系而非孤立的观点出发,考察了中国30个省、市、自治区1990~2005年全要素生产率增长的特征。实证分析的结果表明：创新型人力资本是各地区全要素生产率增长最主要的源泉,同时空间外部性也发挥着非常重要的作用;而作为生产要素的人力资本的提升、技术引进、技术扩散等因素的贡献则表现出较大的地区差异性。如果不考虑地区间的相互作用,就会不同程度地扭曲各种因素对全要素生产率增长的重要性。

In this paper we introduce spatial externality dements representing regional interaction into modds on technological progress of the new economic growth theory, and investigate the patterns of total factor productivity growth of 30 Chinese provinces as a whole rather than separatdy within the period of 1990-2005. The results derived from empirical analysis indicate that innovative human capital served as the main sources of TFP growth for all provinces, and the contribution of spatial externality is remarkable as wdl. However, the roles played by growth rate of productive human capital, technology diffusion, and technology import vary considerably. Ignoring interactions among regions will distort estimated effects of other factors on TFP growth to various extents.
