新收入准则实施提升了会计信息可比性吗?

Does the Implementation of CAS 14 Enhance the Comparability of Accounting Information?

会计准则的变化是否对市场具有正外部性,一直受到监管机构和资本市场的广泛关注。文章以2015-2020年上市公司为研究对象,采用PSM-DID方法研究表明,相比于未实施新收入准则的企业,实施新收入准则的企业会计信息可比性更高。进一步分行业和产权性质研究发现,新收入准则的实施对建筑行业和非国有企业会计信息可比性的提升作用更为显著。调节效应检验发现,内部控制与新收入准则存在替代效应,在提升会计信息可比性方面,新收入准则的实施弥补了内部控制薄弱的不足。外部监督与新收入准则具有互补效应,外部监督有利于新收入准则的高质量实施。中介效应检验发现,新收入准则通过提升财务信息披露质量进而提高会计信息可比性。研究结果为中国会计准则建设与实施的高质量发展提供了启示。

Whether the change of accounting standards has a positive externality to the market has been widely concerned by regulators and capital markets.Taking listed firms from 2015 to 2020 as samples and using PSM-DID method,this paper finds that compared with firms that have not implemented CAS 14,the accounting information of firms that have implemented CAS 14 is more comparable.Group test by industry and property rights finds that the promoting effect of implementation of CAS 14 on comparability of accounting information is more significant in the construction industry and nonstate-owned enterprises.The adjustment effect test finds that CAS 14 and internal control are substitutable,which means the implementation of CAS 14 can make up for deficiencies of internal control in promoting comparability of accounting information.External supervision and CAS 14 are complementary,and external supervision is conducive to the high-quality implementation of CAS 14.The mediating effect test finds that CAS 14 promotes comparability of accounting information by improving the quality of financial information disclosure.The above results provide references for the high-quality development of China's accounting standards.
