人力资本跨部门流动对经济增长和社会福利的影响

The Impact of Inter-sectoral Flow of Human Capitalon Economic Growth and Social Welfare

本文将人力资本跨部门流动引入带外部性的UzawaLucas模型,研究发现:人力资本持续不断地从物质生产部门转移到教育部门一定可以加快人力资本的积累速度;然而,快速的人力资本积累不一定都能促进经济增长、也不一定都能提升社会的整体福利水平。因此,政府发展教育的规模和速度应当和经济发展阶段相适宜。

By introducing inter-sectoral flow of human capitalinto the standard Uzawa- Lucas mode[ with externality, this paperfinds that： （i） perpetual flow of human capital out- side from the final good sector to the education sector could definitelyaccelerate human capital accumulation; （ii） nevertheless, faster human capital accumulation could but do not neces- sarilynourish the economic growth or bring about more social welfare. Therefore, it is not al- ways appropriate for a government to do whatever is necessary to give priority to the develop- ment of education.
