基于随机前沿生产函数的煤炭企业技术效率分析

Analysis on Technical Efficiency of Coal Enterprises Based on Random Frontier Production Function

选取2006年我国煤炭行业17家上市企业的数据,运用随机前沿分析模型,借助EV iews 5.0软件包对其技术进步效率进行了测算。分析结果表明,17家上市企业技术进步的平均效率是0.51,普遍偏低,说明提高我国煤炭行业技术效率是当前亟待解决的问题之一。

By using the panel data of 17 listed coal enterprises of Chinese coal industry in 2006, the efficiency of technical progress in these coal enterprises was estimated with random frontier analysis model and software package EViews 5.0. The results of analysis showed that the overall average efficiency of technical progress for the 17 listed coal enterprises is 0.51 ,is on the low side, thus it is one of problems demanding prompt solution for Chinese coal industry to improve technical efficiency at the current.
