中国航空运输生产函数和成本函数的实证研究

从本质上讲，生产函数反映了生产过程中投入要素的数量与产出量之间的技术关系。定义决定中国航空运输产出量的关键要素为航空运输飞机占用资本、飞行员的飞行驾驶劳动和航空油料消耗，利用C—D生产函数，以中国航空运输总周转量表示产出，以运输飞机数量、正驾驶飞行员人数和航空油料消耗量表示投入，利用1990--2005年中国航空运输生产的相关数据资料，进行模型估计。同时，以生产函数为基础构建航空运输的成本函数，并通过生产函数和成本函数分析中国航空运输生产包括规模经济性在内的一些重要特征。

Empirical Research on Production Function and Cost Function of China Air Transport

Essentially,production function reflects the technical relations between input and output factors. It is supposed that the factors which influence China air transport output are air transport plane capital, pilot driving work and aerial oil consumption. With C-D production function and China air transport product data from 1990 to 2005,model parameter estimation was carried out. In this model China air transport tonne-km performed was regarded as output and transport plane number,pilot number and aerial oil consumption as input. At the same time, the cost function of air transport was set up based on the production function. At last,some features of China air transport product such as economies of scale are analyzed by the production function and cost function.
