基于数据包络分析的我国农业生产效率区域差异分析

Regional Difference Analysis of Agricultural Technology Production Efficiency in China based on Data Envelopment Analysis

摘要:

内容提要：基于数据包络分析方法探讨了1998-2016年全国32个省份的农业生产效率及其变动情况,并利用空间自相关方法对变动情况的空间集聚特征进行了分析,研究结果表明：(1)相对于大陆各省份而言,台湾各年份农业技术的综合效率、纯技术效率及规模效率均达到了最优状态,远高于大陆各省份的均值。(2)全国各省份农业全要素生产率指数都大于1,呈增长态势,但区域差异明显,东部地区的增长速度高于西部地区,西部地区则高于中部地区；台湾农业全要素生产率(TFP)的增长速度要低于大陆均值。(3)根据各省份农业全要素生产率及其分解值的变化特点,可以将全国省份划分为四类问题省份。(4)全国各省份农业全要素生产率增长差异的空间集聚特征较为明显,且集聚趋势逐渐增强,农业全要素生产率的热点省份、次热点省份、冷点省份的变化显著。

Abstract:

The agricultural production efficiency and its changes of China’s 32 provinces is discussed from 1998 to 2016 year based on data envelopment analysis (DEA) method, and its features of space agglomeration are analyzed by using the spatial autocorrelation method,the results show that：(1) Relative to the Mainland provinces,Taiwan’s comprehensive agricultural technology efficiency,pure technical efficiency and scale efficiency all achieve the optimal state each year,and is far higher than the average of Mainland provinces．(2) The total factor productivity index of agriculture in all provinces is greater than 1,showing a growth trend, but the regional difference is obvious,the growth rate of the eastern region is higher than the western region,the western region is higher than the central region；Taiwan"s total factor productivity (TFP) growth rate is lower than the Mainland’s average．(3)According to the change characteristics of agricultural total factor productivity and its decomposition value in each province,the whole country can be divided into four problem provinces．(4) The spatial agglomeration characteristics of the differences in agriculture total factor productivity growth among provinces are obvious and are gradually strengthened；The change of agricultural total factor productivity is obvious in hot provinces,sub-hot provinces and cold provinces．
