Based on the data of listed companies in China's Shanghai Securities Exchange from 2005 to 2007, discussed the relevance between the CFO characteristic variables and the firms' performance. The study showed that the companies' share prices were related to the variables of CFO's gender, duration, and whether holding shares or not. The statistical significance correlation existed between the company's total profit and the variables of CFO's age, education, job title and salary. However, earnings per share and ROE(return on equity) indicators were only associated with CFO's annual salary. The indicators of company's scale correlated significantly with the variables of CFO's gender, age, education, job title and salary. The study had a certain reference value for listed companies to establish the governance mechanisms to inspire and restrict CFOs compatibly.
