我國(guó)審計(jì)市場(chǎng)集中度對(duì)審計(jì)質(zhì)量影響的實(shí)證研究
[Abstract]:In the 21st century, although the real meaning of the audit industry in our country has only been on the road of marketization for a few years, but with the rapid development of our country's securities capital market, it has also made great progress. But in this process, also highlighted a series of problems. Especially since the mid-1990s, the outbreak of malignant cases such as "Qiong Minyuan" and "Hongguang Industry" makes the CPA profession face "the biggest trust crisis ever". Independent audit has received unprecedented attention from all walks of life. More and more industry regulators, academic researchers and audit practitioners begin to study the audit market in China. Based on the theory of economics, this paper studies the A share audit market in China by the method of combining normative research with empirical research. In addition to the introduction, the article is divided into three parts. The introduction first introduces the research background and significance of this paper, and then describes the current research situation and the research framework of this paper. The first part studies the concentration of A-share audit market. Through a brief review of the theory of industrial organization, the theoretical basis of this paper is derived. In this paper, the method of measuring concentration by CRn is put forward. The data of A share audit market from 2004 to 2006 are summarized, screened and classified, and the data about concentration are summarized. Through the analysis of these data, it is concluded that the concentration of A-share audit market is very low. The reasons for this are as follows: 1. The market is over-competitive. The big firm is too small. The small firm is too few. A serious regional factor. Under the principle of the combination of government and market, this paper proposes to improve the concentration of audit market in our country from the following three aspects: 1: 1. Improve the audit market access qualifications. Firms should be encouraged to merge and restructure. To establish a reasonable exit mechanism, guide unqualified firms to withdraw from the audit market, and cultivate firms with high quality, strong strength and outstanding reputation. The second part studies the specialization of A-share audit market. Specialization refers to the firm's focus on doing business in a particular field, and the motive for specialization is: 1. The fine division of labor in society. Audit risk mitigation mechanism. The means of transmitting high quality product signal. The feasible path of the formation of competitive advantage; four aspects have promoted the specialized management of accounting firm. This paper is not a direct study of specialization, but from another perspective, through the comparison of industry concentration and the overall A-share audit market concentration, we analyze the A-share audit market concentration. Statistics show that the degree of specialization of A-share audit market is not high. The third part is an empirical study on the impact of concentration on audit quality. First of all, it reveals the connotation and characteristics of audit quality, which is the probability that auditors find customer breach and are willing to disclose customer default. In this paper, the ratio of non-standard opinions is used to measure the audit quality. According to the statistics of relevant data, the assumption of this paper is put forward: "there is an inverted U-shaped quadratic function relationship between audit market concentration and audit quality in China". Through the regression model test, the regression results verify the hypothesis of this paper. It is concluded that the audit market concentration is still in the first half of the quadratic function and far from the maximum. Therefore, in order to improve the practice quality of audit market in China, we should focus on improving the concentration degree of audit market.
