【摘要】 要素配置扭曲被认为是抑制中国全要素生产率增长的重要因素之一,但其中背后的机制还缺乏足够深入的研究。包含农业部门与非农业部门的两部门模型可就劳动力配置对全要素生产率的抑制作用及其作用机制进行研究。模型的分析结构表明,劳动力在农业部门和非农业部门间的配置扭曲会抑制劳动力从农业部门向非农业部门流动,并阻碍经济从农业向非农业的转型,同时通过这一作用机制也抑制了全要素生产率增长。为了检验这一机制,基于1985—2015年的中国省际面板数据,使用中介效应检验方法进行了实证研究。实证研究结果表明,农业部门与非农业部门间的劳动力配置扭曲确实抑制了经济由农业向非农业转型,并通过这一中介抑制了全要素生产率增长,在考虑了变量的度量方式和解释变量的内生性之后,该研究结论依然是成立。更多还原

【Abstract】 Factor misallocation is considered one of the most critical elements that restrain the growth of total factor productivity in China, but the mechanism behind this relation has not been studied in depth. This paper constructs a twolsector model involving the agricultural sector and the non-lagricultural sector to study the restraining effect of labor misallocation on total factor productivity and related mechanisms. The theoretical study reveals that labor misallocation between the agricultural sector and the non-lagricultural sector will delay labor transfer from the former to the latter, by which labor misallocation will restrain the growth of total factor productivity. In order to test the above mechanism, this paper takes an empirical study by use of China’s provincial panel data from 1985 to 2015 and the mediating effect model. The empirical study shows that labor misallocation between the agricultural sector and the non-lagricultural sector does restrain the economy’s transformation from agriculture to non-lagriculture, and that this effect is the mediating mechanism acting on the effect of labor misallocation on the growth of total factor productivity. This outcome remains robust even we change the measurement of total factor productivity growth and consider the endogeneity of labor misallocation.更多还原
