【摘要】：深圳证券交易所自2004年成立中小企业板块以来，在该板块上市的公司数量增长非常迅速。但是与主板相比，在中小板上市的公司规模相对较小、运营风险较大，特别是公司管理层和外部投资者之间存在着信息不对称的问题，导致投资者可能无法获得准确的信息来进行投资决策，这就使得投资者对在中小板市场投资存在一定的担忧，从而一定程度上影响我国中小板市场的发展。因此，提高中小板上市公司信息披露的完整性，使得投资者获得更多、更详细的信息，是消除投资者担忧、促进中小板市场发展的一个重要方式。本文主要将目前在中小板上市公司中使用的XBRL分类标准分别作为研究中小板上市公司信息披露完整性程度的“工具”和提高中小板上市公司信息披露完整性的“手段”。首先，采用规范研究法，将XBRL分类标准制定的理论基础和中小板上市公司信息披露的内容进行梳理。然后，采用比较研究和实证研究相结合的方法，将XBRL分类标准与中小板上市公司实际披露的信息元素进行匹配，找出二者存在的差异性，并将得到的匹配结果与样本公司对应年度的信息披露评价等级进行相关性分析，从而研究XBRL分类标准在中小板上市公司中的适用性，以及需要改进之处；进一步将中小板上市公司信息披露的不完整程度和可能影响中小板上市公司信息披露完整性的因素进行多元回归分析，找出对中小板上市公司的信息披露完整性存在显著影响的因素。研究发现，（1）目前的XBRL分类标准能够基本适用中小板市场信息披露的要求，但是有些信息元素定义不够全面，仍需要加以改进；（2）我国中小板上市公司信息披露的完整性情况不是很好，公司的规模、大股东持股比例和董事会中独立董事所占的比例能够显著的影响中小板上市公司信息披露的完整性。最后，，提出提高我国中小板上市公司信息披露完整性的对策，认为我国需要在改进目前的信息披露评价等级制度、完善法人治理结构、进一步发挥独立董事在董事会中作用和加强对中小板上市公司信息披露的监管、完善XBRL分类标准元素定义五个方面加以努力。
[Abstract]:The Shenzhen Stock Exchange since 2004 since the establishment of small and medium enterprise board, the growth in the number of listed companies very quickly. But compared with the motherboard, in the small board listed companies are relatively small, operation risk, especially the management of the company and external investors exist the problem of asymmetric information, investors may be unable to obtain accurate result the information to make investment decisions, which makes investors to have some concerns in the small and medium-sized market investment, the development of China's small and medium-sized board market to a certain extent. Therefore, the integrity of the information disclosure of listed companies "senior high school, so that investors get more and more detailed information is to eliminate the concerns of investors and a an important way to promote the development of small and medium-sized board market.

Then, using the method of comparative study and empirical research, by matching the information elements of the XBRL classification standard and the actual disclosure of Listed Companies in the SME board, to find out the differences between the two, and will get the matching results and the corresponding annual Sample Firms information disclosure evaluation rank correlation in order to study the applicability of XBRL classification standards of Listed Companies in the SME board, and needs to be improved; the small board listed company Incomplete information disclosure and the degree of our small and medium-sized board may affect the integrity of the information disclosure of listed companies factors by multiple regression analysis, find out the factors of the SME board information disclosure of listed companies has significant impact on integrity. The study found that (1) XBRL current classification can basically applicable to small and medium-sized board market information disclosure requirements. But some of the information element definition is not comprehensive enough, still need to be improved; (2) the information disclosure of Listed Companies in China's SME Board's integrity is not very good, the size of the company, shareholders and the board of directors in the proportion of independent directors can significantly affect the integrity of the SME board information disclosure of listed companies. Finally, put forward to improve the listed companies in China's SME board information disclosure measures the integrity of that China needs improvements in the hierarchy evaluation the current information disclosure, improve the corporate governance The structure will further play the role of independent directors in the board of directors and strengthen the supervision of information disclosure of small and medium-sized listed companies, and improve the definition of standard elements of XBRL in five aspects.
