国家审计如何更好地维护国家经济安全

维护国家经济安全是国家审计的现实目标。本文从国家经济安全的概念和体现形式入手,深入分析国家审计与国家经济安全的关系,以及维护国家经济安全的审计局限,提出在新的时代背景和历史条件下,应按照维护国家经济安全的目标要求重新定位审计工作的方向和着力点,即以落实权力主体经济责任为主攻方向,强化对公共资源整体性的监督,保障公共资源安全;强化对公共责任落实情况的监督,保障公共权力运行安全;强化对公共政策执行情况的监督,保障公共管理安全;强化对国际竞争引致公共风险的监督,保障宏观经济安全。     

项目管理技术在国家审计项目管理中的应用

项目管理方法和应用工具的不断完善和创新,使得项目管理技术日臻成熟,并大大拓展了项目管理技术方法的应用领域。国家审计项目管理和现代项目管理在理论和实务两方面都具有高度的一致性,项目管理的绝大部分技术都能在国家审计项目管理中得到应用和推广,包括审计项目的计划管理、成本管理、进度管理、风险管理、后评估等多个方面。充分借鉴项目管理技术,可以有效解决我国国家审计项目管理中存在的缺乏审计项目管理标准、项目控制流于形式、审计质量控制流程薄弱、审计风险控制能力差、审计效率低下等突出问题,促进审计工作的科学化和规范化。     

寡头电信企业价格决策微分博弈模型及其分析

在随机需求环境下,电信企业的价格策略表现为一个随时变化的调整轨迹,将寡头电信企业之间的价格竞争博弈刻画为微分博弈模型,并对模型进行了数值模拟和仿真分析,结果表明:在随机需求下,寡头电信企业的价格策略存在唯一的鞍点均衡路径,否则很难实现均衡状态;虽然寡头电信企业的价格处在动态调整中,但市场份额会相对稳定维持在某一均衡状态下。     

集群企业协同竞争研究——以“中国锰都”矿业集群为例

从博弈论角度出发,以"囚徒困境"模型为基础构建了"中国锰都"集群矿业企业协同竞争模型,分析了集群内企业协同的影响因素。发现协同意愿的提高有赖于协同额外收益、协同因子、行业集中度、协同平等关系的提高以及协同成本的降低。     

中国财产保险市场之竞争测度与结构分析

如果只从市场集中度判定市场竞争的程度,难以客观地反映出真实状况,本文使用Bresnahan与Lau提出的BL模型,利用非结构的方法使用更多信息分析我国财产保险市场。在财险公司追求利润最大化的假设下建立模型,采用2002年至2009年数据,对模型参数进行估计,从而分析我国财险市场竞争情况。研究发现,我国市场属于高度竞争的...     

Product Market Competition,Managerial Incentives and Firm Valuation

This paper contributes to the very small empirical literature on the effects of competition on managerial incentive schemes. Based on a theoretical model that incorporates both strategic interaction between firms and a principal agent relationship, we analyse the relationship between product market competition, incentive schemes and firm valuation. The model predicts a nonlinear relationship between the intensity of product market competition and the strength of managerial incentives. We test the implications of our model empirically based on a unique and hand‐collected dataset comprising over 600 observations on 200 Swiss firms over the 2002–2005 period. Our results suggest that, consistent with the implications of our model, the relation between product market competition and managerial intensive schemes is convex indicating that above a certain level of intensity in product market competition, the marginal effect of competition on the strength of the incentive schemes increases in the level of competition. Moreover, competition is associated with lower firm values. These results are robust to accounting for a potential endogeneity of managerial incentives and firm value in a simultaneous equations framework.     

THE SUBSTANCE OF ACCOUNTING FOR PUBLIC‐PRIVATE PARTNERSHIPS

This article evaluates Public‐Private Partnerships (PPP) accounting practice and the related financial accounting and reporting requirements. Governments across the world are seeking to access private finance to improve public infrastructure. Accounting for PPPs has encountered many difficulties, one of which is the practice by which PPPs are not accounted for as fixed assets on the balance sheet of either the public sector client or the private sector operator. Accounting for PPPs has grown in importance at a time of transition from national Generally Accepted Accounting Practice (GAAP) to International Financial Reporting Standards (IFRS). Under UK GAAP, both client and operator accounting adopt the reasoning – familiar from leasing standards – of the allocation of risks and rewards between the parties to determine the party which should recognize the fixed asset on its balance sheet. The gap in IFRS with regard to operator accounting has been filled by the interpretation IFRIC 12 on service concession agreements: this moves the reasoning from risks and rewards to control, familiar from consolidation standards. The UK Treasury and the International Public Sector Accounting Standards Board (IPSASB) have required/proposed the adoption of the mirror‐image treatment of IFRIC 12. In most, but not all, cases, control will be assessed to rest with the client, which will recognize property, plant and equipment, and not with the operator, which will recognize either a financial asset or an intangible asset on the basis of an assessment of which party bears the majority of risks and rewards. Under both UK GAAP and IFRS, accounting policy choices are strongly influenced by, for the client, governmental control frameworks, and for the operator, by the implications for the profile of distributable profits and for taxation. An important public policy issue is that the national accounts, which for European Union member states must comply with European System of Accounts 1995, will remain on a risks and rewards basis. It is these numbers that will be used in assessments of macro‐fiscal policy and fiscal risks, notwithstanding that the Eurostat version of risks and rewards is even more open to manipulation than were the national financial reporting standards.     

长三角区域经济一体化深化发展的思考

随着国务院《国务院关于进一步推进长江三角洲地区改革开放和经济社会发展的指导意见》的出台,长三角区域经济一体化进程进入到新的深化阶段。按照国家战略的总体要求,深入推进长三角区域经济一体化发展,对于增强中国的国际竞争力、增强长三角在全国的辐射带动力、增强长三角自身的可持续发展能力具有重要意义。针对当前长三角区域经济一体化发展面临的区域空间规划、区域共同市场、区域合作制度缺失的制约,今后应着力在优化区域生产力的空间布局、打破区域要素市场的行政分割、建立完善的区域合作制度等方面寻求突破,以此深入推进长三角区域经济一体化发展。
