【摘要】 利用吉林省1989—2005年农户饲养生猪投入产出的面板数据,采用非参数HMB指数方法对生猪生产效率进行分解分析,获取各指数的时序变动趋势和空间分布特征。结果表明:吉林省农户饲养生猪的全要素生产率主要由于规模效率的提高和技术进步而呈递增趋势,各市(县)生猪生产的全要素生产率与其技术进步的变动趋势一致,可以通过扩大生产规模、提高技术进步水平和技术应用的有效性来提高生产效率。更多还原

【Abstract】 This paper is based on the panel data of input-output of hog production in Jilin province in 1989—2005,the methods of HMB index are used to analyze the changes of TFP.The result indicates that the growth of TFP is mainly positively related with the increase of scale efficiency and technological progress.The trends of TFP are the same as technological progress in each city.Suggestions are put forward,such as expanding the production scale and improving the technological progress and the validity of technical application.更多还原
