| The development of the listed company occupies a significant position in the global economy; along with the increasing numbers of listed companies, Accounting restatement is becoming more and more serious. This phenomenon is significant in the United States, Therefore, this phenomenon also caused wide attention in our country between investors, regulators and standards setters. With the development of securities market in our country, Information disclosure has become an important part of capital market, Orderly operation of our securities market is becoming more and more important. Because the securities market is not perfect in reality, and the information asymmetry and agency problems still exist. for example, information disclosure is not timely and earnings are manipulated. This also makes serious information asymmetry between listed companies and external stakeholders, which affect investors to the judgment of the listed company, as a result, the audit opinion and the problem of the external environment, which includes geographic, audit tenure and accounting restatement, at present it is a hot spot in practice and theoretical research, the research of the relationship between them has important theoretical value and practical significance.The paper studies by the way of combining theoretical analysis and empirical test. First of all, the paper explains contact between the auditing opinions and accounting restatement, Geographic and audit tenure; and summarizes some empirical conclusions, then sets up empirical research model of this paper, and chooses relevant data from the non-financial firms listed over the period from 2009 to 2011, in terms that accounting restatement is involved in surplus restatement, which can measure information risk and audit risk, thus we can use risk transfer to study the influence to audit opinion suffering from geography and audit tenure. And we can test the paper to use descriptive statistics, the correlation analysis and multiple linear regression analysis. This article’s conclusion will be present.As the conclusion of the research shows, issuance of the audit opinions in our country’s listed companies are affected by uncertain many factors such as environment. Accounting restatement of the company are more likely to receive non-standard audit opinions; Involving the surplus restatement, information risk is bigger, then this risk will affect relation of geography and the probability of audit opinion. That companies involved in surplus restatement than those not involved in the company of the surplus, nonlocal accounting firm will give the higher probability non-standard opinion. If the listed Company appears accounting restatement, the audit risk will be different. The influence of audit opinion influenced from audit tenure is different. If companies occur surplus restatement, audit risk will be higher, Audit tenure cannot effect the probability of the audit opinion significantly. |
