内生经济增长理论认为,人力资本通过影响技术创新和传播间接贡献于经济增长。本文利用省际数据,引入空间回归方法,包括空间滞后模型和空间误差模型,首先估计了人力资本对技术创新水平的影响;再进一步引入二阶段回归模型,加入空间依赖性,来估计人力资本通过创新影响经济增长的间接作用。本文的主要实证发现包括,从业人员接受高等教育的比例与省域技术创新活动有着显著的正相关关系,但对经济增长的间接贡献不明显。
Endogenous growth theory suggestes that human capital leads to greater innovation and, through technology innovation and diffusion, contributes to economic growth. Using the Chinese provincial data, this study estimates the effect of human capital on innovation based on spatial regression models, specifically spatial lag model and spatial error model. Furthermore, this study estimates the indirect effect of human capital on growth through innovation using spatial two - stage regression model. The main finding is that the workers' tertiary education is significantly and positively related to provincial innovative activities measured by invention patent applications per capita, however its contribution to economic growth through technology innovation is not evident.
