Abstract: Accounting basic professional ethics refers to the behavior and norms that accountants should follow. It reflects the professional skills, professional ethics and influence on the social economic environment of accountants. With the development of the times, financial information has become the basis for the parties to participate in the decision of the social market economy, so the importance of the basic professional ethics of accounting has become increasingly prominent. In recent years, accounting fraud has become more and more serious due to the irregularities of accountants' basic professional ethics, which has affected the development of the social market economy. Therefore, it is urgent to strengthen the construction of accounting professional ethics, improve the moral standard of accountants, resolutely crack down on false accounts, standardize the order of our accounting market and eliminate corruption. Although accounting ethics receives a lot of attention today, many scholars still treat it as a separate discipline, rather than just combining it with false financial statements, fraud, and fraudulent activities. This article delves into the ethical standards of accounting practitioners in China and explores the reasons for this phenomenon from different perspectives. Through this work, it proposes some effective measures to promote the fairness and transparency of China's accounting work and create a healthy financial environment for society.
