On estimating the mean of the selected normal population under the LINEX loss function

Following Parsian and Farsipour (1999), we consider the problem of estimating the mean of the selected normal population, from two normal populations with unknown means and common known variance, under the LINEX loss function. Some admissibility results for a subclass of equivariant estimators are derived and a sufficient condition for the inadmissibility of an arbitrary equivariant estimator is provided. As a consequence, several of the estimators proposed by Parsian and Farsipour (1999) are shown to be inadmissible and better estimators are obtained. Received January 2001/Revised May 2002     

我国商业上市公司的股权结构与公司业绩——基于市净值指标的实证分析

文章以沪深两市55家商业上市公司为样本,对股权结构与公司业绩的关系进行回归分析。结论表明:商业上市公司国有股比例对公司业绩并没有显著的影响,但法人股比例与公司业绩显著正相关,流通股比例与公司业绩显著负相关。同时,第一大股东持股比例与公司业绩没有显著关系,但前五大股东持股比例与公司业绩显著正相关;另外,第一大股东的控制能力对公司业绩有显著的负面影响。     

分布式供能与循环经济的能源结构优化

认为分布式供能为城市循环经济发展过程中的能源结构优化提供了新的选择途径,是传统的集中式供能不可或缺的补充和替代,代表着新型绿色供能模式更新换代的发展趋向,成为许多城市发展循环经济的契入点.认为这一新型供能模式的启动与发展需要城市管理决策者的政策引导和社会力量参与的市场化运作.     

企业技术创新与研究开发探讨

在社会主义市场经济环境中，企业的技术创新和技术研发被提升到一个从未有过的高度，这两个词汇也频频被知识经济下的各种传媒所引用。作者认为，如果对二者没有一个清晰的概念，忽略了它们本质上的差异，那么对“科学技术是第一生产力”就不会有深刻的理解，也无法说清技术对经济的影响，思想的混乱将会导致企业决策和行动的失误。本文结合企业的实际情况，就技术研发与技术创新的表现以及对企业发展的作用和影响，进行分析和探讨。     

违约损失率问题初探

巴塞尔新资本协议强调内部评级法在风险管理和资本监管中的重要作用。内部评级法的关键在于对违约率及其相关因素的测量,其中违约概率(PD)和违约损失率(LGD)是内部评级法的核心变量。对国际上关于LGD的表现及影响因素的讨论进行了总结与分析,并重点对LGD与PD之间的关系进行了介绍。     

Accounting practices and professional power dynamics during a crisis

This paper examines how changes in accounting practices during a crisis can affect organisational dynamics between hospital managers and clinicians. Our theoretical framework applies a multi-dimensional concept of power (Hardy, 1996) – which distinguishes power over resources, processes and meaning – to a longitudinal case study of a public university hospital during a budgetary crisis. Based on interviews with managers and clinicians, three successive time intervals with distinct power constellations are identified. Initially, we identify a pre-crisis phase where management formally controls resources, which seems to have limited effects on clinician dominance because managers lack ‘processual power’ and ‘power of meaning’. Next, an implantation phase emerges whereby the introduction of mandated budget cuts triggers shifts in the distribution of power, such that managers acquire power by securing the collaboration of clinicians – a phenomenon which has tangible benefits in terms of enabling budget compliance and increased service provision. Finally, the third phase may be conceptualized as a fiscal pressure regimen whereby, when budgetary pressures intensify further, management's newly gained ‘power of meaning’ is eroded because management are now seen to pursue unrealistic demands. Drawing on research insights gleaned during each phase, our analysis contributes to extant literature in at least three ways. First, we present novel findings regarding the impact of crises-related applications of accounting practices on intra-organisational power constellations. Second, our work highlights how accounting practices help shape the understanding of crisis, which, in turn, impacts the distribution of organizational power and influences intra-organizational patterns of collaboration. Third, we find that awareness of the meaning power of accounting practices can help shape strategic action in crisis situations.

经济法框架下的国家权力 社会经济权力 社会经济权利

人类社会从野蛮时代向国家社会的发展中伴随着社会权力向国家权力的演变。但是,在国家权力取代社会权力而对社会发展起主导性作用的同时,社会权力又有很大保留。作为社会权力中的社会经济权力在法律层面上就独立于国家权力而存在。社会经济权力存在的基础是社会公共利益的独立性及其与国家利益不同质性。国家在保护阶级利益的同时,维护确认了部分社会利益,在此基础上才形成了社会经济权利。
