摘要
将劳动力要素配置纳入分析框架是厘清粮食节水生产行为收入溢出机制的关键。基于河北、山东、河南540个粮食种植户调查数据,运用工具变量分位数、中介效应和门槛回归模型分析农户节水生产行为的收入溢出机制及异质性。研究表明:节水生产行为能够显著提升农户收入,且农业增收效应大于要素替代效应;节水生产行为的农业增收效应随农业收入水平提升而递增,即“马太效应”,其非农增收效应随非农收入水平提升而递减,即“重心转变效应”;本地非农就业在节水生产行为增收效应中发挥中介作用,外出务工部分遮掩了节水生产行为的收入提升效果;节水生产行为的增收效应随本地非农就业比例增加而上升,随外出务工比例提高而下降。因此,建议完善粮食节水生产的政策扶持与市场机制,引导非农劳动力合理有序就业,强化农村人力资本积累,进而推动农户持续增收。
Taking labor allocation into the analysis framework is the key to clarify the income spillover mechanism of grain water-saving production behavior. Based on the perspective of heterogeneous non-farm employment and the sample survey data of 540 grain farmers in Hebei,Shandong and Henan provinces,this paper analyzes the spillover mechanism of water-saving production behavior on farmers’ income and heterogeneity by using instrumental variables quantile regression,mediating effect and threshold regression models. The results show that water-saving production behavior can significantly improve farmers’ income,and the agricultural income effect is greater than the factor substitution effect.The agricultural income effect of water-saving production behavior increases with the increase of agricultural income level,which is named the Matthew Effect;the non-farm income effect of water-saving production behavior decreases with the increase of non-farm income level,which is named gravity shift effect. Local non-farm employment plays a partial mediating role in the income increasing effect of watersaving production behavior,while migration for work partly cover up the income promotion effect of water-saving production behavior. The effect of water-saving production behavior on farmers’ income increases with the proportion of local non-farm employment,and decreases with the proportion of outworkers. Therefore,it is suggested to improve policy support and market mechanism of grain water-saving production,guide reasonable and orderly transfer of rural non-farm labor force and strengthen rural human capital accumulation,so as to promote the sustainable increase of farmers’ income.
