投入低还是效率低——贫困农户畜牧业收入低的原因剖析

Lower Inputs or Lower Efficiency? Decomposition of Livestock Income of China's Rural Poor Household

贫困农户畜牧业收入较低是困扰我国扶贫工作和畜牧业发展的难题。本文运用农户调研数据和非线性Blinder-Oaxaca分解方法重点剖析了贫困农户畜牧业收入低的原因。结果表明,贫困农户畜牧业中间物质投入的效率低下是最重要的原因,能够解释贫困农户与非贫困农户畜牧业收入差距的96%;劳动力投入少且劳动产出效率低也是贫困农户畜牧业收入低的重要原因,对贫困农户与非贫困农户畜牧业收入差距的贡献分别为39.3%和16.7%。国家未来的扶贫政策和扶贫资金应更加有效地满足贫困农户对发展畜牧业的需求,尤其是提高贫困农户中间投入品和劳动力的使用效率。

China has been experienced with lower livestock income of China's rural poor household,which has affected the progress of China's poverty alleviation and livestock development. This paper uses rural household survey data and nonlinear Blinder-Oaxaca decomposition approach to investigate the causes of lower livestock income. The results indicate that the lower efficiency of intermediate inputs account for 96% of livestock income gap between poor and non-poor rural households. Lower labor inputs and efficiency account for 39. 3% and 16. 7% of the gap respectively.
