政府支出、人力资本积累与经济增长

Government Expenditure,the Accumulation of Human Capital and Economic Growth

首先,在Romer(1986)、Lucas(1988)等研究的基础上,构建了四部门模型,将政府支出分为教育支出与生产建设支出,以分析政府支出、人力资本与经济增长的内在关系,得出了政府支出是人力资本积累与经济增长的重要因素,但其效力的发挥取决于各要素之间比例是否合适的结论。然后,利用1978～2006年中国的数据进行了分析与检验,结果表明,政府支出对经济增长具有强促进作用,政府支出与人力资本的形成存在着不确定的关系,人力资本对经济发展具有较为明显的负向作用。因此认为,我国人力资本积累只是单纯地依赖教育体系供给,缺乏"干中学"效应。

This article, based on the findings of Romer（ 1986）, Lucas（1988）, etc, establishes a four- sector model, in which the government expenditure is divided into education expenditure and produce expenditure in order to analyze the innate relationship between govemment expenditure, human capital and economic growth. Consequently, the conclusion is that government expenditure is responsible for the accumulation of human capital and economic growth, but the extent of the effect is due to whether all the factors maintain a optimal ratio between them. Based on that, the authors use Chinese data in 1978- 2006 to come to the conclusion that goverrunent expenditure strongly contributes to economic growth, government expenditure makes non - specific relationship with the accumulation of human capital, human capital imposes a negative effect on economic growth. As a result, the accumulation of human capital in our country solely relies on the production of the educational system, lacking the ＂learning- by- doing ＂effect.
