目前 ,国内在测算运输业的全要素生产率状况方面所采用的研究方法 ,往往存在需要假定生产成本最小化以及生产率变化因素不能分解的问题 .为此 ,运用交通运输业 1990～ 2 0 0 0年的数据 ,把扩展的Malmquist DEA(曼奎斯特 -数据包络分析 )方法引入交通运输业 ,来测量交通运输业生产率变化总量以及影响因素 ,解决了常用研究方法的弊端 .研究表明 ,对于不同的运输方式 ,其生产率的变化量不尽相同 ,各种影响因素的作用也存在较大差异
At present, the research methods used in China to measure the total factor productivity of the transport industry often have the problem of assuming that the production cost is minimized and that the factors of productivity change can not be decomposed.Therefore, the use of transportation 1990 to 2000 , The extended Malmquist DEA method is introduced into the transportation industry to measure the total amount of changes in the productivity of the transportation industry and its influencing factors and to solve the drawbacks of the commonly used research methods. Different modes of transportation, the changes in productivity vary, the role of various influencing factors are also quite different
