劳动力外出务工对农户水稻生产的影响

The Impact of Labor Migration on Farm Households' Rice Production

文章基于2009年在江西省调研获得的数据,构建了水稻生产函数,从集体农田基础设施投资和家庭生命周期的视角考察了家庭成员外出务工与农户水稻生产之间的关系。实证结果显示,务工者的汇款能帮助农户在水稻生产中投入更多的化肥和农药以提高产量,但务工带来的非农收入的提高又会使他们忽视对水稻生产的管理,导致产量下降;集体农田水利等基础设施投资是稳定水稻产量的重要保证,在基础设施较差的地区,家庭成员外出务工将导致农户水稻生产中出现劳动力短缺,对生产力造成严重影响;外出务工带来的农业劳动力老龄化目前并未使水稻生产力出现明显下降,反而是年轻农户会因外出务工而粗放地经营水稻生产。

Based on survey data from Jiangxi province in 2009,this paper establishes production functions to analyze the productivity changes of farm households in response to the outflowof family members,in the point of viewof village level agricultural infrastructure investment and life cycle theory.The empirical results suggest that the remittance from migrant members can help farm households use more chemical fertilizer and pesticides in rice production to get more yields,while the increase of non-agriculture income weakens their concentration on farm work and hence negatively affect rice output.Migrant households at villages with poor infrastructure may input insufficient labor,sharply reducing the output of rice.
