As one of the focus topics of the current society，corporate financialization is of great significance to the stability of the financial market and the healthy development of the real economy.However，research on whether the financialization of enterprises will affect the auditor's risk decision-making is still not a reality.Based on the sample of Shanghai and Shenzhen A-share listed companies from 2009 to 2017，this paper examines the impact of corporate financial asset allocation on auditor risk decision-making.The research shows that the higher the degree of financialization of enterprises，the greater the probability that auditors will issue non-standard audit opinions，and the higher the audit fees.This conclusion is still established after a series of robustness tests，indicating that auditors can fully identify the process of corporate financialization.There are audit risks and appropriate risk control measures to reduce the risks and losses that may be incurred in the future.Further analysis found that the impact of corporate financialization on audit opinions is more significant in non-state-owned enterprises and companies with poor corporate governance，and the impact on audit fees is not significantly different among the above-mentioned enterprises，indicating that corporate financialization has increased the complexity of the company's business，and the auditing difficulty of the auditor，the auditor will not treat the audit fees differently because of the property nature of the customer and the level of corporate governance.This paper not only expands the research on the influencing factors of auditor's risk decision，but also provides some references for preventing financial risks from the perspective of auditing.
