人力资本积累对我国经济增长影响的机制分析

The Impact of Human Capital Accumulation on China's Economic Growth

随着我国可转移劳动力存量的下降,以提高劳动生产力水平为目的的人力资本积累或是未来推动我国经济发展方式转变的重要动力之一。将资本利用率与代表人力资本积累的劳动生产力作为内生因素引入RBC模型,检验了各主要经济指标对这两个因素的脉冲响应。研究结果发现:在我国经济起飞阶段,人力资本对总产出的贡献要大于资本利用率增长的贡献;相对于资本利用率,以提高劳动生产力水平、降低单位劳动成本的人力资本积累,或是解决我国短期产业加速转移及产业升级滞后所带来的经济增速放缓的有效手段。

As the situation of the decline of the labor supply, the human capital accumulation by promoting the labor productivity can be considered as one of the effective ways to achieve the economic growth. In this paper, the utilization of capital and human capital accumulation have been introduced into the RBC model as the endogenous factors. After testing the impulse response of the major maeroeconomic indicators to these two factors,we found that：the contribution of the human capital accumulation on China＇s economic take-off is more significant than the contribution of capital input; Compared to the increase of capital utilization, the labor productivity improvement and the decline of per unit labor cost which can be considered as the human capital accumulation are the effective ways to lag the economic slowdown under the situation of industry transformation and upgrading in the short-term.
