物质资本、人力资本与经济增长——基于省级面板数据的实证检验

Physical Capital,Human Capital and Economic Growth——The Empirical Test Based on Provincial Panel Data

物质资本和人力资本投入是影响经济增长的重要原因。研究基于扩展的索罗模型和物质资本、人力资本对经济增长影响机制的理论分析,采用1998~2017年中国省级面板数据对物质资本、人力资本与经济增长的关系进行实证检验。结果表明:在研究时段内,物质资本、人力资本以及技术进步等要素均与经济增长之间存在显著正相关,且相比于人力资本而言,物质资本对经济增长的作用强度相对更大,物质资本或仍为推动我国经济增长的主要动力,而人力资本则在经济增长中持续发挥着重要作用。研究认为经济发展新常态时期应在持续优化资本投入结构的同时高度重视人力资本积累。

The factor input of physical capital and human capital is the important reason that affects economic growth. Based on the extended Solow model, the paper explains the influence mechanism of physical capital and human capital on economic growth through theoretical analysis, and conducts an empirical test on the relationship between physical capital, human capital and economic growth by using the panel data of China’s provincial regions from 1998 to 2017. The results show that physical capital, human capital and technological progress factor have significant positive correlation with economic growth during the study period, and compared with the human capital,the effect strength of physical capital on economic growth is relatively larger, physical capital is still the main power to promote the growth of the economy, and human capital has been playing an important role in economic growth.The study believes that it is necessary to continuously optimize the investment structure and attach great importance to the accumulation of human capital during the new normal period of economic development.
