基于随机前沿函数的铁路行业生产效率分析

采用超越对数形式的时变技术效率随机前沿生产函数模型,对我国铁路行业的全要素生产率进行五个维度分解和实证研究.研究表明:铁路行业全要素生产率增长缓慢,前沿技术进步出现较小幅度的上升趋势,相对前沿技术效率变化始终为负值,铁路资源配置效率显著,铁路行业不存在规模经济.因此,铁路行业应适度控制新增、再建项目规模,通过加大科技研发、应用高新技术提高技术水平和加快铁路管理体制改革、合理配置铁路资源才是实现铁路和谐和可持续发展的有效途径

Analysis of Production Efficiency in Railway Industry Based on the Stochastic Frontier Function

This paper applies stochastic frontier function model of timevarying technology efficiency in the form of translog, conducting a fivedimension productivity decomposition and empirical research for total fae tots in railway industry. The research finds out when the growth of railway industry＇ s total factor productivity is slow, frontier technology progress shows a slight rising tendency and the relative frontier technology effieieney change is negative;meanwhile, the railway resource allocation efficiency is remarkable and then there is no scale economy in railway industry. Therefore, to realize the harmonious and sustainable development of the rail way industry, China should carry out the moderate control on new project scale. It is important to enhance the scientific research and development, adopt high and new technology to improve the technical level and speed up railway management system reform, and rationally allocate railway resources.
