电子商务的风险管理与审计研究

电子商务尽管现在处于低潮期，但是作为重要的变革力量，它仍然是2l世纪的一个必然趋势。另外，电子商务发展受阻的一个重要原因就是电子商务的安全问题，这一问题影响了消费的决策，也极大地改变了企业的整个风险结构。本从外部审计与内部审计两个角度分析了审计可以在应对电子商务风险中发挥的重要作用。从外部审计来看，数据完整性与机密性是网站审计与认证的重要方面，从内部审计来看，审计应该在包括了电子商务风险的全面风险管理框架内发挥重要的作用。     

The effectiveness of the ECB’s unconventional monetary policy: Comparative evidence from crisis and non-crisis Euro-area countries

During the European financial crisis, the European Central Bank implemented a series of unconventional monetary policy measures. We argue that these programs lowered the bond yield spreads of Euro-area countries. This hypothesis is tested using pooled OLS estimations and two different datasets: monetary policy event dummies and the purchase volumes of the Securities Markets Programme (SMP). Overall, we find significantly negative effects on bond yield spreads for both datasets, leading us to accept the hypothesis. While the OMT reduces the spreads of both crisis and non-crisis countries, LTROs and the lowering of the deposit rate to 0 percent are mainly effective in non-crisis countries. The SMP lowers the spreads of crisis countries, but it has the opposite effect on non-crisis countries. This converse effect is explained by the risk that increasingly accumulates on the ECB’s balance sheet through the SMP and that way constitutes a fiscal risk for non-crisis countries. The results are confirmed by pooled OLS estimations that measure the effect of unconventional monetary policy on central government debt.     

How do suppliers benefit from customers’ voluntary disclosure? the effect of customers’ earnings guidance on upstream firms’ investment efficiency

We explore whether and how the issuance of customers’ financial forward-looking information affects the investment efficiency of their upstream firms. Using earnings guidance as a proxy for forward-looking information, we find that firms wherein customers disclose earnings forecasts invest more efficiently than those where customers withhold forward-looking information. Our findings hold after controlling for a set of firm characteristics, employing alternative model specifications and measurements, and using the 2011 Thailand flood as a quasi-experiment. Further analyses offer support that the positive impact of customers’ earnings guidance on upstream firms’ investment efficiency is stronger for customers issuing more informative, disaggregated, and accurate forecasts and suppliers with weaker bargaining power. We also observe an asymmetric response of suppliers’ investments toward customers’ good-news versus bad-news forecasts. Furthermore, by conducting a textual-based analysis, we find that suppliers’ investment efficiency increases with more embedded supply chain relevant information in customers’ earnings guidance reports. Overall, our findings suggest that suppliers benefit from customers’ earnings guidance to better assess their investment decisions, thereby achieving greater investment efficiency.     

医院的企业文化体系内涵与核心能力培育

医院文化(Hospital Culture Management,HC)和医院文化管理(Hospital Culture Management,HCM)是医院管理的重要组成部分。医院文化可以分为显性文化和隐性文化二类,前者指管理规章制度体系,后者指企业的价值观、道德伦理和经营宗旨等方面,两者互为促进。为开展好医院文化建设管理,笔者给出了5个方面的建议,这些都是基于笔者长期实践的认知。     

Accounting change and value creation in public services—Do relational archetypes make a difference in improving public service performance?

Evidence points out that the outcome of accounting change in local governments is not simply a matter of ‘corporate’ resource investments and change management activities to accounting system replacement. This paper examines the link between such corporate-level interventions and the patterns of value creation at street-level. It emphasizes a resource- and capability-driven approach to explore processes and consequences of an ‘embedded agency’-effect assigned to the street-level rationale of public service improvement. Considering a logic chain of cause-and-effect sequences, the data analysis provides evidence that corporate and street-level interventions are unique dimensions to signify the multiple patterns of accounting change in local governments. The supplementary effect of cross-functional relationships is also distinguished, considering the relational archetype as a mechanism to explain the emerging outcome state. Recognizing the distinction and the sequential effects of relational archetypes induces a refined typology of accounting change according to its processes and outcomes in local governments. The analysis is based on a comparative case study design to explore accrual accounting introduction in six German municipalities.     

The role of strategic enterprise risk management and organizational flexibility in easing new regulatory compliance

The impact of new regulatory requirements for internal control reporting on an organization's ability to maintain strategic flexibility has been debated in the popular press extensively. This paper tests theory from strategic management to examine the relationship between an organizations' pre-regulatory strength of strategic enterprise risk management (ERM) processes and their ability to react to new regulatory mandates. In the context of companies' adoption of SOX Section 404 internal control reporting requirements, we examine organizations' pre-SOX ERM processes, ERM supporting technologies, and organizational flexibility in order to better understand the antecedents to the difficulty encountered in meeting SOX 404 requirements. Using responses from 113 Chief Audit Executives (CAEs), we find that organizations with stronger strategic ERM processes and flexible organizational structures already in place incurred little difficulty in implementing SOX 404 mandates. On the other hand, organizations using weaker ERM processes, which focused on control compliance, experienced more difficulty. These findings provide key insights into the importance of strategic ERM in effectively complying with new regulatory controls in volatile environments.     

The use of management control mechanisms by public organizations with a network coordination role: A case study in the port industry

Our paper addresses two gaps in the literature on management control mechanisms in the context of inter-organizational relationships. Firstly, several studies have focused on one-to-one relationships, but few take a network perspective which analyses the deployment of management control mechanisms in the context of networks involving multiple interactions between organizations. Secondly, even fewer studies have specifically tackled the use of these mechanisms in the context of mixed-type networks, where a public organization acts as the network coordinator responsible for key governance activities. This is the position in Ports, which are collectives of several related organizations and in which one organization – the “port authority” – assumes the role of network coordinator. In this paper we report the results of a case study, the aims of which were: to identify the management control mechanisms deployed, or relied upon, by the Portuguese Port Authority in the Port of Aveiro in the exercise of its coordinating role; and to discern – on the basis of theoretical reasoning and empirical evidence – the factors explaining the nature and use of these mechanisms.Several conclusions emerged from the study. A general conclusion was that our prior literature-based theorization is generally consistent with the case observations. That is, in mixed-type networks, the nature and use of management control mechanisms by the public organization acting as a network coordinator seems to be shaped by its assessment of motivations to cooperate and of the contribution to network performance of the various organizations involved in the network. Other more specific conclusions are encapsulated in a “coordination framework”, which relates those assessments to specific features of the management control mechanisms. Crucially, our results provide insights into the roles of public organizations acting as network coordinators in the context of mixed-type networks, and, in general, on the nature of the numerous such public organizations in today's economy and society.     

政府财务报告图像印象管理策略研究——基于美国州政府财务年报的调查

政府财务报告作为政府形象传播的主要载体之一,可能会利用图像提升积极形象或者挽回消极形象。为探索地方政府财务年报中的图像是否存在印象管理行为,本研究以美国州政府官网出具的财务年报为样本,运用内容分析方法,识别图像进行印象管理行为的六种策略,并建立影响因素、印象管理动机和策略数量的理论逻辑框架。研究表明:(1)政府财务年报中的图像涉及的财务指标主题达到62%,每张图像的印象管理策略数量为0.73;(2)公众财务年报(PAFR)的图像数量和印象管理策略数量均显著高于综合财务年报(CAFR);(3)外部刺激因素与图像防御策略数量显著正相关,经济水平与政治选举因素与图像印像管理总策略数量显著负相关。
