基于集中式模型的我国各地区及三大产业的DEA效率评价

基于集中式模型, 首先在考虑地区内部三大产业的情况下, 对2010年我国31个地区展开DEA效率评价, 然后在保持各地区整体效率不变的前提下进行效率分解, 确定各产业的效率值和相对重要程度. 此外, 对各地区三大产业的规模收益问行了研究. 实证分析结果表明, 各地区的整体效率值偏低, 第一产业的效率重要程度偏低, 第二产业和第三产业的效率均值相差不大, 但大部分地区的产业比第二产业的相对重要程度高. 此外, 从规模收益角度来看, 大部分地区整体处于规模收益递减阶段, 大多数地区的第一和第三产业均处于规模收益递增阶段, 绝大多数地区的第二产业已处于规模收益递减阶段.

Measuring the DEA efficiencies of regions and their three major properties in China based on centralized model

Based upon the centralized model, it first measured the data envelopment analysis (DEA) efficiencies of 31 regions of China in 2010 with considering their internal three major properties. Then it obtained the efficiency and the relative importance for each property using the efficiency decomposition method in the premise of keeping the region efficiency unchanged. Moreover, it also investigated the returns to scale (RTS) of each property in each region. The empirical results indicate that overall efficiencies of regions are relative low. The efficiency and the relative importance for the primary property are relative low. There is a small difference for the average efficiencies of the secondary property and tertiary property, but the relative importance for the tertiary property is higher than the secondary property in most of regions. In addition, from the perspective of the RTS, most of regions are in the stage of the decreasing return scale (DRS). The primary property and tertiary property in most of regions are in the stage of the increasing return scale (IRS). The secondary properties in most of regions have been in the stage of the DRS.
