The Research of Cost Efficiency of Chinese Automobile Manufacturing Enterprises Based on Stochastic Frontier Analysis Model

This paper,using data of 50 listed automobile manufacturing enterprises over the period 2006-2009,applies the stochastic frontier analysis model to study the cost efficiency and analyzes the influence on cost efficiency of the ownership concentration,the scale,the zone and so on.The empirical results show as follows: the more ownership concentrates,the lower cost efficiency is;the cost efficiency of the largest shareholder,which is state-owned share,is higher than non-state-owned;the scale of firms and cost efficiency are positive correlation,i.e.,the larger the scale of firm is,the higher cost efficiency is;the cost efficiency of the east zone is higher than the west zone,and the cost efficiency of the west zone is higher than the middle zone.In total,the cost efficiency of Chinese listed automobile manufacturing enterprises concentrates on(0.9,1),which shows efficiency loss is very little.
