市场经济初期地区行政垄断对规模经济的作用机制分析——基于钢铁、汽车工业规模效率的动态测算

An Analysis on the Relationship between Local Administrative Monopoly and Scale Economy—Based on the Dynamic Scale Efficiency of Steel and Mobile Industries

本文首先提出了中国转型过程中存在的追求"模糊产权租金"的地区行政垄断这一概念,并从理论上分析了追求"模糊产权租金"的地区行政垄断对于行业规模经济影响的作用机制,提出了基于此分析的三个命题。然后,以规模经济特征比较显著的钢铁、汽车工业为典型案例,运用DEA模型测算了其技术效率、纯技术效率、规模效率的损失,并通过对规模效率的动态变化趋势的观察,初步验证了本文提出的三个命题。最后,本文又对地区行政垄断对于规模效率的影响进行了实证检验。

Local administrative monopoly for'vague property rights rent',which existed during the transition of China,is first raised in this article.And its effect on scale economies of industries is analyzed,thereafter three statements is proposed.Take steel and mobile industries for example.Their scale efficiency is calculated by DEA model.Finally,the relationship between local administrative monopoly and scale economy is tested,which proves the three statements mentioned above.
