Research On Technical Efficiency And Its Affecting Factors Of Beijing Public Traffic Enterprises

Urban public transport is necessary for survival of urban public infrastructure. Improving the efficiency of public transport industry,we can quickly provide residents with convenient,safe and efficient,economic and comfortable travel service.In recent years,with increased demand for urban travel,the number of cars increased,so that multiple constraints faced by urban traffic,in turn,to create enormous pressure on urban development.In order to alleviate the urban traffic pressure on Beijing in the last century 80's opened the first municipal public utilities as urban public transport market, the introduction of small buses,in the same line appeared in a number of business situation,which at that time to alleviate widespread due to lack of capacity caused by the difficulty of the car played a role.At the same time,the Government set up enterprises in the public transport system to achieve more than by the main industry and the separation of the asset allocation optimization.These market-oriented reform measures to enhance the efficiency of public transport companies? Non-governmental enterprises to set up self-financing is more efficient? To further ease city traffic jams, Beijing in 2005 defined the priority to the development of urban public transport strategic decision-making,and increased capital investment,and in 2007 on the IC card 4 passengers discount fare concessions,the people measures to significantly enhance the public transport enterprises of passenger traffic.On the efficiency of public transport enterprises and how?Based on the interest in these questions,this article of the existing public transport industry in China study reviewed the literature and found that current public transport industry for the research while an increasing number of research lit rature is not more efficient,but these studies in data,an empirical model to study the methods there are some flaws.Such as the use of enterprise data is estimated industry production function, the simple use of CD production function testing without the use of industry time-series data rather than panel data and so on.In this paper,panel,therefore the use of industry statistics,the use of generalized translog production model.Public transport enterprises and technological progress can be tested,on the technical efficiency of China's automobile industry had an in-depth research.The main contents of the article is as follows:The first section describes the development of public transport in our country,as well as problems in the status quo; The second part of the development of public transportation in Beijing and the future direction of public transport enterprises in Beijing's market reform,operating conditions and the state of urban public transport enterprises to carry out an analysis of subsidies.PartⅢanalyzes the microeconomics of technical efficiency and technical efficiency of the current main measurement method.PartⅣof the stochastic frontier production function model and cost function, introduced the form of the main model.And CD production function model as an example of maximum likelihood estimation methods and statistical examination process. Finally,in Beijing as an example of public transport enterprises to build a generalized translog production function form,and the correctness of this production function and the existence of technological progress is verified.Came to the conclusion that the efficiency of the calculation results and to improve the technical efficiency of public transport enterprises put forward policy recommendations.The main innovation lies in the development of Beijing Public Transport industry and market-oriented reforms have done a more systematic summary,for production and technical efficiency model calculation using a more scientific research methods,in Beijing the efficiency of public transport enterprises carried out depth studies and to draw some meaningful conclusions.In this paper,the Beijing public transport companies to use the production function of setting the general translog model,and hypothesis testing related to verify the correctness of assumptions,the use of statistical data panel,but also to improve the accuracy of the study.These are the current efficiency of public transport traffic study of a rare occurrence.
