基于广义Malmquist指数的江西早籼稻生产率分析

Analysis on Productivity of Jiangxi Early Indica Rice Based on Generalized Malmquist Index

为了解江西省早籼稻生产率状况,提高农户早籼稻生产率,利用2009-2013年江西省早籼稻生产成本收益追踪调查数据,采用产出定位的随机前沿方法,使用广义Malmquist指数分析江西省早籼稻的全要素生产率。结果表明。1)江西省早籼稻生产率提升主要得益于技术进步,技术效率和规模效率对早籼稻生产率贡献较小。2)江西省早籼稻生产率北部地区高于南部地区,其中,奉新县和南昌县最高,会昌县和遂川县最低。

In order to explore the current status of Jiangxi early indica rice productivity and enhance it,out-put oriented stochastic frontier analysis method was employed to analyze the total factor productivity by using generalized Malmquist index based on the survey data of cost of production during 2009-2013.Results：1）Technological advance promoted Jiangxi early indica rice productivity,technical efficiency and scale efficiency contributed less to the productivity;2）The productivity of Jiangxi early indica rice in the north was higher than that in the south,which was the highest in Fengxin County and Nanchang County,and the lowest in Huichang County and Suichuan County.
