中文摘要：

行业专长是审计师核心竞争力的重要体现，拥有行业专长的审计师更有意愿和能力发挥其公司治理作用。本文以2001-2014年我国上市公司为样本，检验了审计师行业专长对企业费用粘性的影响。研究发现，审计师行业专长水平越高，企业费用粘性越低，并且这种关系在国有企业中更显著。使用缓解内生性问题的二阶段最小二乘法和相关稳健性测试，均得到了一致的研究结论。从审计师行业专长角度研究企业费用粘性问题，不仅有助于进一步识别审计师发挥治理作用的机制和情境，而且对降低企业的费用粘性以提高资源配置效率具有重要的借鉴意义。

英文摘要：

Industry expertise is an important manifestation of auditors＇ core competency. Auditors with industry ex- pertise are more willing and able to facilitate corporate governance. Based on data of Chinese listed companies from 2012 to 2014, this paper empirically tests the impact of auditors＇ industry expertise on cost stickiness. The empiri- cal results show that：the higher level of auditor industry expertise, the lower is cost stickiness; the relation is even stronger when the enterprises are state-owned; the two-stage least squares regression method, which was used to alleviate endogenous problems, and the related robustness tests both generated consistent research conclusion. This paper is helpful not only in iden also in reducing cost stickiness, tifying the mechanisms and scenarios which affect auditors＇ role in governance, but providing reference to the improvement of efficiency of resource allocation.
