【摘要】：会计稳健性是重要的会计信息质量特征，表现为不高估资产/收益，，不低估负债/损失。高质量的会计信息是稳健的，完善的公司治理结构对会计信息质量具有重要影响，公司治理的效率与模式很大程度上取决于公司股权结构，以往许多学者的研究已经证实股权结构会影响公司的会计信息质量。因此本文将在此基础上进一步探讨作为会计信息质量特征之一的会计稳健性在不同股权结构下的敏感度。同时分析在股权分置改革阶段，我国股权结构的变动对会计稳健性产生的影响。本文以我国2007 2010年沪深两市A股上市公司为样本，采用多元回归分析和因子分析方法进行全样本和分年度检验。实证结果表明：流通股比例与会计稳健性正相关，国有股比例与会计稳健性负相关，股权集中度与会计稳健性负相关，第一大股东处于绝对控股时与会计稳健性负相关，相对于非国有股，第一大股东为国有股时，会计稳健性更低。通过行业分组后发现，相对于垄断和垄断竞争行业，一般竞争行业下不同股权结构与会计稳健性存在显著相关性，而我国总体上体现出的会计稳健性基本上是一般竞争性行业引起的。进一步分析股权分置改革引起的股权结构变动对会计稳健性产生的影响，本文认为在股权结构相对稳定时期，公司存在较强的稳健性，且不同股权结构对会计稳健性的影响很明显，但在股权结构变动较大时期无论是公司整体稳健性还是股权结构对稳健性的影响都显著降低，因此股权结构变动会对会计稳健性产生影响。本文认为现阶段我国上市公司稳健性较低，股权结构对稳健性的影响减弱，公司应加强对会计稳健性的关注。
[Abstract]:Accounting conservatism is an important characteristic of accounting information quality, which is shown as not overestimating assets / income, not underestimating liabilities / losses, and high quality accounting information is prudent. Perfect corporate governance structure has an important impact on the quality of accounting information, and the efficiency and mode of corporate governance largely depend on the corporate equity structure. In the past, many scholars have proved that equity structure will affect the quality of accounting information. Therefore, this paper will further explore the accounting conservatism as one of the characteristics of accounting information quality in different ownership structures. At the same time, it analyzes the reform stage of split share structure. The influence of the change of China's equity structure on accounting conservatism. This paper takes the A-share listed companies of Shanghai and Shenzhen Stock Exchange in 2010 as samples. The empirical results show that the proportion of circulating shares is positively correlated with accounting conservatism, while the proportion of state-owned shares is negatively correlated with accounting conservatism. Ownership concentration is negatively correlated with accounting conservatism. When the first shareholder is in absolute control, it is negatively correlated with accounting conservatism. Compared with non-state shares, the first largest shareholder is state-owned. Accounting conservatism is lower. Through industry grouping, it is found that there is a significant correlation between different ownership structure and accounting conservatism in general competitive industries compared with monopoly and monopoly competition industries. The accounting conservatism in our country is basically caused by the general competitive industry. Further analysis is made on the influence of the change of the equity structure caused by the reform of the split share structure on the accounting conservatism. This paper holds that in the period of relatively stable equity structure, the company has strong conservatism, and the influence of different ownership structure on accounting conservatism is obvious. However, in the period of great change of equity structure, both the overall robustness of the company and the impact of equity structure on the robustness are significantly reduced. Therefore, the change of ownership structure will have an impact on accounting conservatism. This paper holds that the listed companies in our country have lower conservatism and weaker influence of equity structure on conservatism at present, so companies should pay more attention to accounting conservatism.
