人力资本对农业劳动供给的影响——基于分数响应模型和无条件分位数回归模型

Effects of Human Capital on Agricultural Labor Supply:Based on the Fractional Response Model and the Unconditional Quintile Model

人力资本积累是实现经济增长的重要来源,而在农业规模经营成为中国农业现代化必然选择的情况下,家庭自有农业劳动力投入有利于实现规模效应,加速农业相对剩余劳动力转移,促进中国劳动力资源优化配置和"人口红利"的第二次开发。基于这一现实背景,本文构建家庭劳动供给的理论模型和实证模型,结合家庭农场问卷调查数据,采用分数响应模型、基于RIF中心方程法的无条件分位数回归模型,分析规模经营条件下人力资本对家庭农业劳动力供给的影响。内生性分析与稳健性检验的研究结果表明:人力资本的影响存在异质性,主要表现为家庭劳动力平均年龄的影响呈现先下降后增长的U型;随家庭平均受教育年限的增长,其对农业劳动供给影响呈现下降趋势的负作用。因此,提高家庭劳动力人力资本水平,将能增加规模经营农户的农业劳动供给。

The reallocation of labor is one of sources of economic development,and under the condition of agricultural scale operation,family agricultural labor supply can promote the agricultural development and the relative surplus labor’s transformation.In order to increase the efficiency of labor allocation and China’s economic development.Based on the unitary model,we construct theoretical model and empirical model,and use family farm investigation data as sample data of Fractional Response Model and the Unconditional Quantile Regression,find out factors concerned human capital have different effect on agricultural labor supply at different percent quantile,which mainly includes:family average age’s effect increase firstly and decrease successively that process is like a shape of U,the average of education year have a negative effect while it express the trend of decrease as the value increasing.Therefore,the improvement of family members’human capital will increases the agricultural labor supply of household that operates family farm.
