【摘要】 规模经济问题是产业组织理论研究的重要课题之一。汽车产业是中国从20世纪50年代就开始重点扶持的产业,鉴于其产值大、产业链条长、产业关联度高,是一国工业技术水平的综合体现,所以它是许多国家、也是我国国民经济中的重要产业。此外,汽车产业还具有非常明显的规模经济特征。因此,无论中国还是外国都将汽车生产企业的规模经济作为一个重要课题进行研究。在对国内外相关学者研究进行综述的基础上,本论文以产业组织理论为依据,以规模经济理论为指导,采用利润分析法、生存法、比较分析法以及利用数据包络分析(DEA)等计量研究方法,对中国汽车生产企业的规模经济问题从多个角度进行了实证分析和研究。研究证明多数中国汽车生产企业未处于规模有效区间,生产经营效率偏低;同时,研究估计出中国汽车生产企业的最优规模区间大约是15～33万辆,在此区间内多数中国汽车生产企业可获得规模经济效应。此外,通过对影响中国和外国汽车生产企业规模经济的因素进行比较分析,本研究认为中国汽车企业最优规模经济较小是因为受制于比较低的研发投入以及需求长期没有得到满足等多个因素的影响。本文最后从技术创新、政府管制、满足市场需求等角度就如何提高中国汽车生产企业的规模经济提出了相关的政策建议。更多还原

【Abstract】 Economies of scale is one of the main study topics in industrial organization theory. Automobile industry is the heavyly supported one by Chinese government from 50th of 20 centry.Since its big output value,long industry chain,high industrial linkage, automobile industry is a complex reflection of a country’s technical level and an important industry in many countries’ national economy and as well as in China.And since it showes obviously characteristic of scale,both China and other countries take the economies of scale of automobile industry as an important study topic.Based on former reletive studies,and guided both by industrial organization theory and theory of economies of scale,this paper makes a multi-angle positive study on scale economy of Chinese automobile industry by many analytical methods,such as profit analysis method,survivor technique method,regression analysis method and DEA model.The study showes that most Chinese automobile enterprises are in diseconomies of scale for poor operation.And the study guesses that optimal scale of Chinese automobile enterprises now is between 150000～330000,inside the interval enterprises are supposed to get scale merit.Then,the paper makes a comparative study about the influence factors of scale between Chinese and foreign automobile enterprises,and thinks that reletively lower R&D,demand which was not be met and other reasons made Chinese automobile enterprises’ smaller scale.At the end,the paper brings forward the study conclusion and gives out some policy suggestions from the point of technology innovation, government control,demand satisification and others for higher Chinese automobile enterprise’ scale.更多还原
