林业主产区农户影子工资对家庭劳动供给影响的实证分析

Empirical Analysis on Influence of Shadow Wage on Labor Supply of Farmer Households in China’s Main Forestry Production Areas

本文利用1990—2001年我国四川省沐川县、安徽省金寨县480户农户的数据,采用Translog函数和C-D生产函数对样本林业主产区农户在林业、种植业、畜牧业和非农业的影子工资进行估算,并利用Heckman两阶段模型分析了影子工资、影子收入、户主年龄、户主受教育程度、家庭负担等因素对农户劳动供给的影响。研究结果表明:样本林业主产区农户的影子工资与劳动供给时间存在负向关系,闲暇对于农户家庭中男性和女性来说是劣质品;农户家庭劳动供给的联合决策特征非常明显;农户家庭劳动力存在主次之分,该结论对于说明农户家庭内劳动分工以及劳动力流动有一定的指导意义。

Based on the data of 480 farmer households in Muchuan county of Sichuan and Jinzhai county of Anhui during 1990-2001,this paper estimates the shadow wages of farmer households in main forestry production areas in the industries including forestry,planting, animal hus- bandry and non-farming by C-D function and Translog production function,and analyzes the influence of shadow wage, shadow income, farmer householder ~s age and education level and family burden on labor supply of farmer households. The results show that,there is the negative rela- tion between shadow wage and labour time; the leisure is the inferior goods for men and women in farmer household family;the characteristic of joint-decision in labor supply of farmer households is obvious;farmer households labors can be divided into the preliminary and the secondary, which can explain the labor division of family inner as well as labor mobility in a certain degree.
