| 摘 要： | 基于Malmquist指数的DEA方法,以主产品产量、副产品产值为模型的产出变量,以仔猪重量、精饲料数量、青粗饲料数量、其他物质与服务费用和用工数为模型的投入变量,将四川生猪产区散养生猪的生产效率的变化与全国平均情况进行了对比分析。结果表明,四川散养生猪产量的增长主要是投入的增长而非生产效率的提高。

| Abstract: | Based on DEA of Malmquist exponent,host product output,by-product output value were taken as output variables,and piglet weight,concentrated feed quantity,rude green feed quantity,other service charge,the number of labor were taken as input variables,then the production efficiency of Sichuan live pig and the Chinese average condition were comparative analied.The results showed that that the increment of live pig output in Sichuan wasn't owed to the improve of production efficiency,but the increment of input quantity. |
