| 摘要: |
| 为研究我国2011—2012年间31个行政区乳品产业链发展的效率变化,利用DEA-Malmquist指数方法,分别从两阶段乳品产业链整体及其各个阶段2个层面考察各地乳品产业效率变化情况。首先将区域的乳品产业链作为整体(黑箱),计算和分析2011—2012年间31个地区全要素生产效率(TFP)变化,得出TFP指数平均为1.04,增加的主要因素是技术进步和规模增加。然后打开黑箱,分别计算和分析构成整体产业链的第一和第二阶段TFP指数,第一阶段TFP平均为0.97,第二阶段TFP平均为1.04。研究结果显示整体和两级乳品产业链产中乳品生产业较原奶生产业更具有行业领导力,乳品生产业中技术进步、技术效率变化、纯技术效率变化和规模效率变化对乳品产业链中TFP变化有很大的影响。 |

| Abstract: |
| In order to conduct the research on the dairy industry chain efficiency in Chinese 31 administrative districts from 2011 to 2012, using DEA-Malmquist index method, the whole dairy industry efficiency changes were investigated both from the whole level and the individual levels respectively.Firstly, making the dairy industry chain in the region as a whole (black box), the total factor productivity (TFP) was calculated and analyzed in these 31 districts from 2011 to 2012.The result showed that the TFP index average is 1.04 and the main factors for increasing are owing to the technological progress and increase in the scale.Secondly, opening the black box, the TFP indexes of the first and second stages were calculated and analyzed respectively.It was found that the TFP average of the first phase is 0.97 and for the second phase it was 1.04.The research showed that the dairy industry in the whole and the two-stage production of the dairy industry chain had more leadership power than the original milk production industry.The technical progress, technical efficiency changes and purely technical efficiency changes and scale efficiency changes in the dairy industry had a great impact on the TFP changes of the dairy industry chain. |
