Does It Punish One Person as A Warning to Others? A Study on the Spillover Effect of Individual Auditor Punishment：A Perspective Based on the Auditors with Common Audit Experience

【中文摘要】基于组织行为学的惩罚溢出理论，以审计意见作为审计质量的替代指标，本文研究中国证监会针对审计师个体处罚对有共同审计工作经历审计师审计质量的影响。研究发现，审计师个体处罚使得上述审计师在未来更倾向于对客户出具非标准审计意见。本文进一步探讨了审计师处罚对上述审计师审计质量影响的作用机制，发现审计师处罚的溢出效应只存在于共同审计工作经历 次数较多的未被处罚的审计师以及在共同审计工作经历中担任复核角色的未被处罚的审计师之中，这一结果与学习效应的解释吻合。本文还研究中国证监会针对审计师个体的处罚对上述审计师审计定价的影响，发现处罚会提高审计收费。本文的研究表明中国证监会对审计师个体的处罚存在溢出效应，对理解审计质量的形成以及相关部门的监督效果具有重要意义。 【Abstract】Abstract：Based on the theory of organizational penalty spillover and using audit opinion to proxy for audit quality，this paper examines the effect of CSRC's punishment for individual auditor on the others with a common audit experience. This paper finds that CSRC's punishment will make the abovementioned auditors more inclined to issue modified audit opinions in the future. This paper also explores the mechanism of auditor punishment effect on the audit quality of the abovementioned auditors，and finds the spillover effect of auditor punishment exists only in the auditors with more common audit work experience and playing a review role in the common audit work experience，which is more in line with the learning effect theory. This paper further studies the effect of CSRC's punishment on audit pricing to abovementioned auditors and finds that will improve audit fees after punishment. The findings in this paper show that CSRC's punishment for individual auditor has a spillover effect，and there is an important significance to understand the formation of audit quality and the supervision effect of related regulators.本文为国家自然科学基金“审计师处罚的溢出效应研究”（71702032）、福建省社会科学研究 基地重大项目“领导干部自然资源资产离任审计对资源型、重污染型企业投融资行为的影响研究”（2016JDZ040）、福建 省中青年教师教育科研项目“金牌董秘当选的影响因素和经济后果研究”（JAS160161）、福建省高校杰出青年科研人才培 育计划项目和福建农林大学科技创新专项基金项目“上市公司财务重述后换‘师’不换‘所’问题研究”（CXZX2016224） 的阶段性成果

Prediction of Energy Resolution in the JUNO Experiment

International audienceThis paper presents the energy resolution study in the JUNO experiment, incorporating the latest knowledge acquired during the detector construction phase. The determination of neutrino mass ordering in JUNO requires an exceptional energy resolution better than 3% at 1 MeV. To achieve this ambitious goal, significant efforts have been undertaken in the design and production of the key components of the JUNO detector. Various factors affecting the detection of inverse beta decay signals have an impact on the energy resolution, extending beyond the statistical fluctuations of the detected number of photons, such as the properties of liquid scintillator, performance of photomultiplier tubes, and the energy reconstruction algorithm. To account for these effects, a full JUNO simulation and reconstruction approach is employed. This enables the modeling of all relevant effects and the evaluation of associated inputs to accurately estimate the energy resolution. The study reveals an energy resolution of 2.95% at 1 MeV. Furthermore, the study assesses the contribution of major effects to the overall energy resolution budget. This analysis serves as a reference for interpreting future measurements of energy resolution during JUNO data taking. Moreover, it provides a guideline in comprehending the energy resolution characteristics of liquid scintillator-based detectors
