进入管制与中国服务业生产率——基于行业面板的实证研究

Access control and the productivity of China 's service industry——Empirical study based on industry panel

本文研究了我国服务业管制政策对行业生产率的影响。运用一个基于服务产品的垄断-竞争模型,本文分析了管制对生产率的作用机制:管制强化了垄断,不利于高效率企业的进入和在位企业的创新。经过对2003—2010年的省级面板数据检验发现,当放松管制体现为国有以及集体企业垄断力量的下降时,它与全要素生产率增长有显著的正面关系;当放松管制体现为私营以及外资企业实际进入和市场自由化时,它与生产率增长存在负面或不相关的关系。以上结果可能是我国服务业垄断性过强、市场化程度不够的表现。

This article studies the influence of China＇ s services control policy on industry productivity. Adopting a monopoly -competition model based on service products, this article analyzes the mechanism of control on productivity： control enhances monopoly, and it does harm to the access of highly - efficient firms and the innovation of the existing firms. The test on the provincial panel data from 2003 to 2010 shows that： if deregulation means the decrease of monopolistic power of state - owned and collective enterprises, it has an obviously positive relationship with the growth of TFP; and if deregulation means market lib- eralization and actual access of private and foreign - funded firms, it has negative or irrelevant relationship with productivity. The results above could be the reflections of excessively strong monopoly of China＇ s service industry and insufficient marketization.
