Audit opinion types on listed companies are the important accounting reference for investors' scientific decisions and for the government' effective supervision. The research aspect is being transferred from the audit subject to the audit object in recent years. By using the pooled OLS model based on the unbalanced panel data, and the fixed effect model, random-effect model and population-average logistic model based on the balanced panel data of China' private listed firms over the period of 2007 to 2011, this paper empirically examines whether corporate governance affect the audit opinion types. The results show that firms with higher quality of corporate governance are easier to receive qualified audit opinions.
