中文摘要：

文章以我国财政部、工商总局联合推动的会计师事务所向“特殊普通合伙组织形式”转制这一特色事件为契机，基于审计师法律责任的视角，选取2008—2013年我国A股上市公司及其主审会计师事务所为样本，动态实证分析事务所转制对审计质量的影响。研究结果表明：具备证券资格的事务所全部完成特殊普通合伙转制之后，审计质量的整体水平显著提升；而且有限责任制转换为特殊普通合伙制增加了审计师的法律责任，同时也提高了其法律风险意识。具体表现为：转制之后，审计师对高法律风险客户的盈余管理容忍度下降，也更倾向于对高风险客户出具非标审计意见。由此可见，我国会计师事务所特殊普通合伙转制方案取得了显著成效，这将有利于我国注册会计师行业的持续发展和做强做大。
