摘要
文章在数据包络分析的CRS、VRS、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,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5年处于规模收益递减阶段,其余的5年规模收益不变,这说明我国轿车生产企业平均规模不是太小,而是偏大了。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年有一半的时间处于规模不经济的状态。
Based on the CRS,VRS,and NIRS data analyzing models, the paper establishes a mathematic model to evaluate the scale economy of Chinese car enterprises. Making an empirical analysis of the scale economy of Chinese car enterprises from 1992 to 2001, it finds that in five years the scale economy is decreasing, while in the rest five years the scale benefits remain the same. It indicates the average scale of Chinese car enterprises is not too small, but big. Owing to the low output efficiency of Chinese car enterprises and limited market demand, Chinese car enterprises have been in the scale but not economic state for five years during the ten years.
