中国大豆主产区生产效率的实证研究

The Efficiency Analysis of the Major Soybean Producing Areas in China

利用中国10个大豆主产区1988—2007年的大豆投入产出面板数据,采用非参数Malmquist指数方法对大豆生产的效率变动进行分解分析,并运用数据包络分析法(DEA)对Malmquist指数及其分解的各指数的变动情况做出进一步探讨。结果表明,中国的大豆生产全要素生产率(TFP)主要由于技术进步指数上升而呈现平稳上升趋势,因此,可以通过促进技术进步和调整生产规模等手段来提高大豆生产效率。

This article is on the base of panel data with out-input of 10 major soybean producing areas from 1988-2007. Non-parameter Malmquist index method is used to decompose the efficiency changes of soybean production. At the same time, DEA method is applied to search the reason of the changes of TFE The results show that the growth of soybean TFP is mainly promoted by the technical change. Therefore, we can improve the technical efficiency and adjust the production capacity to increase productivity.
