Accounting is a language to record economic life, and with the rapid development of productivity and economic and social progress in China, accounting standards are constantly updated to meet the needs of accounting practice and promote the effective operation of socialist market economy.

In this paper, from the development history of CAS, through the analysis of the causes and effects of the overall differences and specific differences between the two systems on the financial statements of enterprises, combined with the SWOT-PEST model, we make a reasonable outlook on the development of CAS.
