本文从产业组织的视角,利用2001～2005年我国A股审计市场的面板数据,分析了进入壁垒、生产能力扩张这两种竞争因素对我国证券审计市场竞争的影响。结果表明,2000年后证券审计市场政策性进入壁垒提高后,短期内证券审计市场价格竞争有所削弱。但在长期,外生的需求增长导致各事务所生产能力快速扩张,使得市场竞争加剧。从整个研究时期看,进入壁垒提高带来的“减缓竞争”效应仍大于生产能力扩张带来的“竞争效应”。
This article uses the panel data of A-share audit market in China from 2001 to 2005 from the perspective of industrial organization to analyze the impact of two competition factors, including barriers to entry and expansion of production capacity, on the competition in China’s securities audit market. The results show that the price competition in the securities audit market will be weakened in the short term after the policy barriers to entry in the securities audit market increase after 2000. However, in the long run, the increase in exogenous demand has led to the rapid expansion of the production capacity of various firms and intensified market competition. Throughout the research period, the “slowing competition” effect brought by the entry barriers is still greater than the “competitive effect” brought by the expansion of productive capacity.
