  Certified Public Accountants (CPAs, 注册会计师) refer to professionals who have obtained CPA certificates and practice in accounting firms, engaging in auditing, consulting, taxation, and related services. Accounting firms (事务所) are independent legal entities established under Chinese law, composed of Chinese citizens, that accept commissions from investors and stakeholders to provide accounting, auditing, enterprise management consulting, and related services.

  With China's economic development, the audit market has continuously expanded, demonstrating rapid growth in the CPA industry in recent years. According to the 2018-2019 Development Report of China's Certified Public Accountant Industry released by the Chinese Institute of Certified Public Accountants (CICPA, 中国注册会计师协会), the total business revenue of China's CPA industry reached 40.561 billion CNY in 2018, representing a 17.95% increase compared to 2017.

  Per the China Certified Public Accountant Industry Development Plan (2016-2020) formulated by CICPA, China aimed to establish a comprehensive management system by 2020, including 1 central-level unit, 3 regional units, 6 provincial-level units (including cities with independent planning status), 100 prefecture-level units, and 600 county-level units.

  CnOpenData compiles CPA and accounting firm information, covering CPAs, branch offices of accounting firms, and regulatory penalties against firms, with fields such as Firm Name (事务所名称), Approval Document Number (批准执业文号), Practice Certificate ID (执业证书编号), Administrative Region (行政区划), Establishment Date (成立时间), Penalty Type (处罚类型), and CPA Count (注师数量).
