基于卢卡斯模型的人力资本外溢效应研究--对重庆的实证检验

摘要

Human capital, as an important factor of endogenous economic growth, on the one hand, directly involves in eco-nomic production process and has a direct effect on economic growth; on the other hand, has indirect effect on economic growth through affecting other product factors. This paper makes an empirical study on the spillover effects of human capital of Chongqing from 1990 to 2011, based on Lucas human capital spillover effects model. The results show that the output elastic-ity of human capital spillover effects is significant during the samples in Chongqing , but due to the growth of human capital itself being too slowly, the actual driving effect of human capital has a small role on economic growth. Economic growth relies mainly on material capital in Chongqing, which shows typical rough characteristics. So, some suggestions including human capital development, investment in education and labor market development are put forward to strengthen human capital in-vestment and accumulation in order to promote economic growth.%人力资本作为经济内生增长的重要因素，一方面直接参与到经济生产过程，对经济增长有直接作用，另一方面，还通过影响其他生产要素的生产率，对经济增长有间接作用。本文基于卢卡斯的人力资本外溢效应模型，实证检验了1990-2011年重庆人力资本的外溢效应。研究结果显示，样本期间重庆人力资本外溢效应的产出弹性十分显著，但由于人力资本自身的增长过于缓慢，其对经济增长的实际推动作用偏小；重庆经济增长主要依靠物质资本的推动，经济增长表现出典型的粗放型特征。为此，论文从人力资本开发、教育投入和劳动市场开拓等方面，提出了加强人力资本投资和积累以促进经济增长的对策建议。
