本文采用随机前沿生产函数模型度量并比较了各种不同产业、不同地区、不同隶属关系和不同所有制企业的效率,发现企业效率在不同产业、地区和不同隶属企业之间,各年的效率差异明显表现出缩小的趋势。在比较产业之间的相对效率时发现,竞争的市场结构导致较高的企业效率,而垄断的市场则产生了较低的效率。在考察地区间效率差异时发现,高效率并非完全与高市场化地区具有相一致的趋势,而是趋向于具有资源分配优先权的地区。
In this paper, we use the stochastic frontier production function model to measure and compare the efficiency of different industries, different regions, different affiliations and enterprises with different ownership, and find that the efficiency of enterprises in different industries, regions and different affiliated enterprises, the efficiency of each year was significantly different Showing a trend of shrinking. When comparing the relative efficiencies among industries, we find that competitive market structure leads to higher enterprise efficiency, while monopolized markets produce lower efficiency. When examining the differences in efficiency among regions, it was found that high efficiency did not completely coincide with the higher marketization regions, but tended to be regions with priority of resource allocation.
