智力外流、人力资本积累与经济增长——基于我国省级面板数据的实证研究

本文利用2001-2010年的中国省级面板数据,采用系统广义矩估计的方法,就智力外流通过作用于人力资本积累对流出国经济增长的影响进行实证检验。研究结果显示:(1)中国智力外流通过激励人力资本形成与积累显著促进了国内的经济增长;(2)内陆欠发达地区智力外流的人力资本激励效应的边际作用比较大,而沿海发达地区人力资本影响经济增长的效果更强,总体来看,智力外流的经济增长效应在沿海发达地区更加明显;(3)通过引入交互项,本文还发现智力外流通过人力资本激励效应对经济增长的影响随智力流动规模的扩大而提高,进一步引发对中国最优智力外流水平的思考。

Brain Drain, Human Capital Accumulation and Economic Growth --An Empirical Study Based on Chinese Provincial Panel Data

Based on Chinese provincial panel data from 2001 to 2010,this paper tests the effect of brain drain on Chinese economic growth with human capital mechanism by adopting the GMM as the analysis method.Such results are drawn:(1) Chinese brain drain significantly improves domestic economic growth by stimulating the formation and accumulation of human capital;(2) marginal utility of human capital stimulation mechanism is bigger in inland less developed regions,while the effect of human capital on economic growth is better in coastal developed regions.All in all,the influence of brain drain on economic growth is more powerful;(3) by introducing the interaction term,the authors also find that the economic effect of brain drain increases with the expansion of the scale of intelligence flow by human capital stimulation mechanism.This paper will lead to further thinking of Chinese optimal level of brain drain.
