摘要
在汽车产业中,市场份额,特别是产业集中度等对企业利润率有显著的正面作用,而企业规模等则对利润率有显著的负面影响。这表明,汽车产业存在明显的垄断利润,而且主要是产业所共有的垄断利润;由于垄断,大企业也产生X—低效率,进而对利润率产生负面的影响。因此,为提高汽车企业的效率和产业竞争力,我们必须首先促进和完善企业之间的竞争。
In auto industry, concentration rate and market share both have significantly positive impact on the rate of return, while firm size has significantly negative impact on it. These suggest that, first, there is marked monopoly profit which is largely industry-owned, second, large firms possess X-inefficiency as the result of monopoly which affects the firms＇ profit. In order to improve the efficiency of auto firms and the competency of auto industry, we must promote and perfect the competition among firms.
