With the development of the market economy, the modern enterprise system emerged as the times require. Company ownership and management rights are separated, and professional managers are responsible for managing the enterprise. Professional managers regularly provide owners with financial status, operating results, and cash flow accounting information to reflect the performance of their fiduciary responsibilities and provide a basis for owners to make accurate economic decisions.

In order to improve the credibility of financial statements, owners need third-party audit institutions to issue audit reports to reasonably ensure that the financial information provided by operators is true and reliable so that appropriate economic decisions can be made.

The CPA audit was created to improve the credibility of financial statements. In order to meet the needs of the client and constantly respond to the increasingly complex audit environment, it has gone through three stages: account-based audit, system-based audit, and risk-oriented audit.

The development of market economy is the root of the CPA system.

In addition, accounting professional ethics has also attracted much attention in recent years. Professional ethics refers to the behavioral norms and standards that should be followed in the accounting industry, and is crucial to ensuring the authenticity and reliability of accounting information. As an important part of the accounting industry, the level of professional ethics of certified public accountants directly affects the reputation and image of the entire industry. Therefore, CPAs must strictly abide by professional ethics and always maintain integrity, fairness and integrity to ensure the provision of true and reliable financial information and make greater contributions to economic development.

In 1978, my country implemented the reform and opening up policy, and foreign investors poured in in large numbers, necessitating the establishment of a CPA system.

In December 1980, my country rebuilt its CPA system and achieved rapid development.

In our country, certified public accountants play a huge role in the market economy. First, they promote the improvement of the quality of accounting information of listed companies and strengthen the state's supervision of listed companies; second, they maintain the market economic order, ensure that market participants carry out activities within the framework of laws and regulations, and prevent fraudulent behavior in market transactions. Enhanced the confidence of all parties to the transaction; finally, they promoted the reform of state-owned enterprises, promoted the restructuring and listing of state-owned enterprises, optimized resource allocation, and economic structural adjustment. This fully illustrates the important position and role of certified public accountants in the market economy.

CPAs ensure the authenticity and reliability of corporate financial information by providing independent third-party audit services, thereby promoting the development of the socialist market economy with Chinese characteristics and the healthy development of enterprises.
