摘要
在数据包络分析的CR2、C2GS2、NIRS模型基础上,建立了一个评价中国轿车企业规模经济的数学模型,并对1992￣2001年中国轿车企业规模经济效益进行了实证分析,发现其中的7年处于规模递减阶段,其余的3年规模收益不变。这说明我国平均的轿车生产企业规模偏大了。这是由于我国轿车企业的投入产出效率太低,加之市场需求有限,致使我国轿车企业10年中有7年的时间处于规模不经济的状态。
Based on the CR2, C2GS2 and NIRS model of Data Envelopment Analysis, this paper founds a model of evaluating the Chinese car enterprises' relative return to scale.And study the Chinese car enterprises' relative returns to sca le from 1992 to 2001.The author finds returns to scale of the car enterprises are diminishing in seven years of the ten years, and returns to scale of the car e nterprises are in scale economy in the other three years.It means that average scale of the Chinese car enterprises is not too small but too large.Because the i nput-output ratio is low and the demand of the car is small so that the car ente rprises of China are in diseconomy of scale in seven years of the ten years.
