中国汽车产业技术效率分析——基于中国汽车行业上市公司2006—2008年的经验证据

本文利用中国汽车行业上市公司2006—2008年的年报数据资料,运用数据包络分析法对中国汽车产业2006—2008年的技术效率进行测算和分析。研究结果表明:①虽然部分汽车行业上市公司的规模收益处于递增阶段,但是汽车行业部分上市公司纯技术效率的下降致使我国汽车行业上市公司的总体技术效率呈下降趋势;②在技术效率前沿面运行的汽车行业上市公司只占全部汽车行业上市公司的一半左右,中国汽车行业上市公司技术效率水平的差异化加剧;③在全球金融危机背景下,大多数的汽车行业上市公司利润大幅下降,达到技术效率前沿面(即纯技术效率和规模效率均有效)的上市公司的抵抗风险能力要大于技术效率较低的上市公司。鉴于此,有必要同时提高我国汽车行业上市公司的技术和规模对技术效率的贡献度。

Analysis on Technical Efficiency of Automobile Industry in China: Based on Empirical Evidence from Chinese Listed Companies in Automobile Industry During 2006-2008

Using the annual report data about 16 China＇s listed companies in automobile industry over the period of 2006-2008 and the method of Data Envelopment Analysis, this paper calculates and analyzes the technical efficiency of China＇s automobile industry in recent years. The result shows that：ahhough some listed companies in automobile industry of China are at the stage of increasing returns, the decline of pure technical efficiency of some listed companies in automobile industry results in the downtrend of total technical efficiency of listed companies in automobile industry;only half of listed companies operate on the frontier of technical efficiency,and the difference in technical efficiency of listed companies in China＇s automobile industry has intensified;in the background of globe financial crisis,the profit of many listed companies has been declining,and the abilities of listed companies at technical efficiency frontier to resist risk are tronger than those with the lower technical efficiency. Therefore,the contribution degree of the factors of technology and scale to technical efficiency for listed companies in China＇s automo- bile industry should be improved.
