基于Malmquist指数的客车企业效率研究

汽车行业是中国加入WTO后受冲击最大的行业之一。正确估计作为公共交通主要工具的客车企业的效率是研究、规划、调控该行业发展的重要依据。本文运用基于DEA模型的Malmquist研究了2002年到2005年中国客车类上市公司纯技术效率、规模效率、技术进步率和全要素生产率的变化。结果表明面对外资企业的冲击,多数企业的发展高于人们的预期,在激烈的竞争中保持住了竞争优势,并实现了一定程度的生产率提高,只是受发展环境的限制,提高速度低于国民经济增长速度。

Efficiency Study on Passenger Car Corporations Based on Malmquist Index

To be a member of WTO has heavily influenced the development of Chinese passenger car industry.Exact estimate of the development of total factor productivity and its components can benefit the study,plan and regulation of passenger car industry.This paper studies pure technological efficiency,scale efficiency,technological change and total factor productivity change of Chinese listed passenger car companies based on DEA model over the period of 2002-2005.The results indicate that the efficiency of passenger car corporations is better than expected.Facing the drastic competency and environment constraint,they experience an increase in TFP lower than GDP.
