本文旨在测算18个城市共64个道路公共交通运营商的技术效率,并研究各因素对这些企业效率水平的影响程度.随机前沿分析(SFA)方法采用从2000年至2011年共计12年的样本数据.结果表明,营业利润、资本投入和企业规模都是影响技术效率水平的重要因素.计算得出的道路公共交通运营商的技术效率水平在0.46至0.95之间.投资较多的大规模运营商比小规模运营商技术效率更高,发达国家的运营商比发展中国家表现出更高的技术效率.
The purpose of this paper is to measure the technical efficiency of 64 road public transport operators in 18 cities and to study the impact of various factors on their efficiency.The stochastic frontier analysis (SFA) method uses a total of 12 years from 2000 to 2011 Sample data.The results show that operating profit, capital investment and firm size are both important factors affecting the technical efficiency.The calculated technical efficiency of road public transport operators is in the range of 0.46 to 0.95.The large-scale Operators are more technically efficient than small-scale operators, and operators in developed countries show greater technical efficiency than developing countries.
