国有控股企业实施股权激励相关问题研究

股权激励作为一种有效解决企业委托与代理问题的长期激励机制,在国外企业中广泛实施,并取得了极大的成功。我国的国有控股公司也逐渐引进了股权激励。本文主要从股权激励的发展历程进入手,探讨了国有控股公司实施股权激励的现状及存在的问题,最终得出结论认为我国国有控股公司实施股权激励还需不断探索,任重道远。     

独立董事责任险、机构投资者与公司治理

独立董事责任险(独董险)强化了独立董事的独立性和信息监督动机。董事会独立性的提高有助于机构投资者提高治理效率。实证分析认为,独董险和机构投资者形成显著的共同治理效果。一方面,对于管理层代理问题,独董险与机构投资者的共同机制对管理费用率有显著的控制作用,形成对显性代理行为的有效监督;机构投资者对ROA有显著的提升能力,一定程度弥补了独立董事对隐性代理行为监督上的不足。另一方面,独董险和机构投资者对国有公司信息披露质量有提高作用。独董险可以强化对披露信息的监督动机,机构投资者有助导入国有公司缺失的独立董事外部声誉约束。在信息监督过程需要较多时间和专业知识投入的情况下,两者对独立董事的激励作用形成互补。     

基于风险视角的董事会相对权力与产品市场竞争力关系研究

利用2004~2012年928家深沪上市公司9年8 352个年度样本的大样本面板数据,从董事会治理风险的角度,验证了董事会相对管理层权力对公司产品市场竞争力的影响,检验了股权集中度和控股股东性质对两者关系的调节作用。研究发现,在不考虑股权集中度和控股股东性质的调节作用时,董事会相对权力同产品市场竞争力存在显著正相关关系;在考虑股权集中度和控股股东性质的情况下,股权集中度对董事会相对权力与公司产品市场竞争力之间关系有显著负向调节作用,控股股东性质对董事会相对权力与公司产品市场竞争力之间关系有显著负向调节作用。

随着我国经济的快速发展,伴随着规模不断的扩大,企业在公司治理和财务控制方面出现了很多的问题,本文通过对公司治理和财务控制的分析,认清两者之间的关系,认为目前我国企业的公司治理在董事会的财务控制和经理人的激励约束方面存在缺陷,进而通过完善财务组织结构,完善董事会监督控制和经理层激励机制,组建专业化的监事会和加强内部审计来改善我国公司治理的财务控制。     

制度变迁、国家控股与股权激励

本文在代理理论的框架下,基于中国国有企业与制度变迁背景,就经理人股权激励与公司价值关系进行分析,并以2001-2006年宣告实施股权激励国有上市公司为样本,实证检验了股权激励对公司价值的改善作用。结果发现,对国有企业的经理人实行股权激励能提高公司价值,受地方政府控制的公司,股权激励更能明显增加公司价值。并且,股权分置改革这种制度变迁进一步改进了原有的激励效果。上述研究发现为理解国有企业治理机制的改善、资本市场改革提供了一个有益的视角。     

关于双向声誉机制的作用机理及有效性研究

以公司治理困境为切入点,讨论如何配置公司股权结构既能发挥股东的支持行为,又能增强经理人的主动性,最终促进企业自主创新行为。整合代理理论与行为动机理论,引入经理人创新动力作为中介变量,并将市场竞争程度和创新空间作为调节变量加入模型,探讨股权集中度对自主创新行为的作用路径,利用182家企业的调研数据进行模型检验。研究结果表明,股权集中度与经理人创新动力、自主创新行为之间都存在倒U形关系,股权集中度通过经理人创新动力间接影响自主创新行为,创新空间正向调节经理人创新动力与自主创新行为间的关系,且这一调节效应不影响经理人创新动力中介作用的发挥,市场竞争程度的调节作用并不显著。     

政府干预、机构持股与公司业绩

为切实保护中小股东利益,股权分置改革是我国二元股权结构的上市公司改革的必然之路,文章研究了股权分置改革前和改革过程中,作为中小股东代表的机构投资者对公司业绩的不同影响。首先从机构持股比例和持股的机构数量两方面研究了机构投资者与公司业绩的关系,发现当机构持股比例较高时,持股机构数目越多,公司绩效越好,而在机构持股比例较低的一组,得到了相反的结论。然后,创造性地研究了股权分置改革与机构持股的交互作用对所持股上市公司绩效的影响,以及股权分置改革前后,国有控股与机构持股的交互作用对上市公司绩效的影响。结果显示,股权分置改革与机构持股的交互作用与公司绩效负相关,而且,股权分置改革过程中国有控股与机构持股的交互作用对公司绩效产生的负面影响大于股改前的。     

公司治理机制互动的实证研究

解决公司中的委托代理问题和有效监督管理层需要各种治理机制共同发挥作用.利用2002年～2005年中国上市公司的平衡面板数据,研究大股东股权竞争、董事会构成、经营者股权激励和监事会行为4种公司治理机制的互动关系.实证结果显示,大股东股权竞争与董事会构成之间存在替代效应,大股东股权竞争与经营者股权激励、董事会构成与监事会行为之间存在互补效应,这表明中国上市公司的治理机制关系呈现出复杂的特性.这一研究结论为继续深化中国的公司治理改革提供了经验证据,提高公司治理水平需要理顺各种公司治理机制的关系.实现治理机制的协同发展.     

公司治理模式对企业绩效的影响

狭义的公司治理是指企业内部界定、调节股东与管理层关系的一套规则和机构,主要是股东大会、董事会、经理层及界定它们相互关系的一套运行规则。公司治理的基本内容是保护投资者的利益,包括股东尤其是中小股东的利益,在广义上也包括债权人。企业要在融资市场上获得优势,在很大程度上取决于投资者对企业公司治理运行情况的判断。     

股权激励、董事会、TMT团队与经营绩效——基于中国上市公司的实证分析北大核心CSSCI

本文以深圳中小企业板上市公司2005-2007年有关数据为样本,对中小企业板上市公司的董事会成员及高层管理团队(TMT)成员股权激励与绩效的相关关系进行了实证检验,对二者的激励效果进行了对比研究。研究结果表明,董事会及TMT成员的股权激励与绩效均呈现显著的正向相关关系,且对TMT的激励效果显著强于对董事会的激励效果,故企业应加大对TMT团队成员的激励,以提高激励效果。研究结果还显示,董事会及TMT股权激励与绩效均存在显著的四次相关关系,同时还求出了对董事会和TMT股权激励的持股比例的拐点:TMT股权激励的拐点为19.72%和45.55%,董事会股权激励的拐点为25.73%和52.73%。     

Criteria for selecting a production control philosophy

Logistic objectives constitute a compromise between having short leadtimes and a low volume of work in progress on the one hand and a high resource loading and due date obligation on the other. Miscellaneous production planning approaches offered today provide different combinations of logistic objectives for satisfying a manufacturing strategy. To combine the strength of the various approaches into a unified system, a new approach based on a dynamic and distributed production planning methodology is proposed. To customize the approach, various analyses and specifications have to be made and for that reason some important characteristics and criteria for analysing production control philosophies will be given.     

The social construction of the meaning of acute stressors: a qualitative study of the personal accounts of police officers using a stress counselling service

The police profession is one in which acute stressors are encountered more frequently than in other occupations. Using the personal accounts of 35 police officers attending an in-house stress counselling clinic, the aim of the present study was to provide a qualitative examination of how the institutional context of policing influenced the ways in which acute stressors signified to individual police officers experiencing felt distress. Using the framework of Rational Emotive Behaviour Therapy as an analytical tool, it is argued that beliefs contributing to the experience of felt distress are related to the way in which policing as both an identity and an activity is constructed through the police organizational culture. Not only do these constructions influence the ways in which officers perceive themselves and their environments, but they also operate at the collective level to 'normalize' some emotional responses and to 'pathologize' others which, it is argued, could impact upon the outcomes of interventions such as stress counselling.     

The moderating role of social support in Karasek's job strain model

This paper examines whether social support is a boundary-determining criterion in the job strain model of Karasek (1979). The particular focus is the extent to which different sources of social support, work overload and task control influence job satisfaction, depersonalization and supervisor assessments of work performance. Hypotheses are tested using prospective survey data from 80 clerical staff in a university setting. Results revealed 3-way interactions among levels of support (supervisor, co-worker, non-work), perceived task control and work overload on levels of work performance and employee adjustment (self-report). After controlling for levels of negative affect in all analyses, there was evidence that high levels of supervisor support mitigated against the negative effects of high strain jobs on levels of job satisfaction and reduced reported levels of depersonalization. Moreover, high levels of non-work support and co-worker support also mitigated against the negative effects of high strain jobs on levels of work performance. The results are discussed in terms of the importance of social support networks both at, and beyond, the work context.     

Job insecurity, coping resources and personality dispositions in occupational strain

This paper presents research on the relationships between the work-related stressor of perceived job insecurity and various indicators of occupational strain, taking into account employees' personality dispositions (trait negative and positive affectivity) and coping resources. Respondents were 222 Australian public servants surveyed during organizational restructuring that involved downsizing and threat to job certainty. The research was formulated within an adaptation of Osipow, Doty, and Spokane's (1985) framework of stress-strain-coping that included the possible direct as well as moderating effects of personality dispositions in reporting occupational strain (Parkes, 1990). Findings from hierarchical regression analyses indicate consistent significant independent effects of personality dispositions, coping resources and perceived job insecurity on various indicators of strain. There was also support for the moderating roles of negative affectivity and self-care in the relation between perceived job insecurity and physical strain. Implications for the role of dispositional factors, especially negative affectivity, and the utility of various coping resources in accounting for occupational strain in times of threatened job security are discussed.     

Introduction to Special Section on Sensitivity Analysis and Summary of NCSU/USDA Workshop on Sensitivity Analysis

This guest editorial is a summary of the NCSU/USDA Workshop on Sensitivity Analysis held June 11–12, 2001 at North Carolina State University and sponsored by the U.S. Department of Agriculture's Office of Risk Assessment and Cost Benefit Analysis. The objective of the workshop was to learn across disciplines in identifying, evaluating, and recommending sensitivity analysis methods and practices for application to food‐safety process risk models. The workshop included presentations regarding the Hazard Assessment and Critical Control Points (HACCP) framework used in food‐safety risk assessment, a survey of sensitivity analysis methods, invited white papers on sensitivity analysis, and invited case studies regarding risk assessment of microbial pathogens in food. Based on the sharing of interdisciplinary information represented by the presentations, the workshop participants, divided into breakout sessions, responded to three trigger questions: What are the key criteria for sensitivity analysis methods applied to food‐safety risk assessment? What sensitivity analysis methods are most promising for application to food safety and risk assessment? and What are the key needs for implementation and demonstration of such methods? The workshop produced agreement regarding key criteria for sensitivity analysis methods and the need to use two or more methods to try to obtain robust insights. Recommendations were made regarding a guideline document to assist practitioners in selecting, applying, interpreting, and reporting the results of sensitivity analysis.     

Job stress, job strain, and psychological withdrawal among Dutch university staff: towards a dualprocess model for the effects of occupational stress

This study examined the antecedents of job strain (emotional exhaustion, health complaints) and withdrawal behaviour (e.g. lowered organizational commitment) among a cross-sectional sample of 131 academic staff members of the law department of a large Dutch university. Conservation of resources theory (Hobfoll, 1989) provided the theoretical background for this study. Strains and withdrawal behaviours were expected to be most prominent among those who reported having few resources and/or who reported high job demands. Structural equation modelling revealed that this was indeed the case. As predicted, differential patterns of effects emerged for job demands and job resources. Analysis of the effects of four job-specific stressors revealed that especially the structural aspects of a staff member's teaching task (e.g. the number of students in their classes) contributed strongly to perceived job demands. Theoretical and practical implications of the study are discussed.     

Distinguishing traumatic, vicarious and routine operational stressor exposure and attendant adverse consequences in a sample of police officers

Problems in studying occupational stress within the police service are identified and the paucity of work on operational duties as potential stressors are discussed. The present study reports the results of a factor analysis of operational stressors (N = 601 serving British police officers) that revealed three factors: exposure to death and disaster; violence and injury; sexual crime. These were demonstrated to be reliable scales and were included in logistic regression models together with a range of demographic and psychological variables. Models were applied to men and women separately, which showed there to be different predictors of the likelihood of suffering distress (measured by the General Health Questionnaire, GHQ) in terms of the officer's gender and operational role. Overall the model for women officers was better at predicting psychological distress than that for men. These findings are related to aspects of the police occupational culture. Further discussion is offered that conceptualizes police operational stressors as traumatic, routine and vicarious. Finally, some implications are drawn for the provision of stress intervention in the light of this differentiation.     

Dermal Uptake of 18 Dilute Aqueous Chemicals: In Vivo Disappearance‐Method Measures Greatly Exceed In Vitro‐Based Predictions

Average rates of total dermal uptake (K_up) from short‐term (e.g., bathing) contact with dilute aqueous organic chemicals (DAOCs) are typically estimated from steady‐state in vitro diffusion‐cell measures of chemical permeability (K_p) through skin into receptor solution. Widely used (“PCR‐vitro”) methods estimate K_up by applying diffusion theory to increase K_p predictions made by a physico‐chemical regression (PCR) model that was fit to a large set of K_p measures. Here, K_up predictions for 18 DAOCs made by three PCR‐vitro models (EPA, NIOSH, and MH) were compared to previous in vivo measures obtained by methods unlikely to underestimate K_up. A new PCR model fit to all 18 measures is accurate to within approximately threefold (r = 0.91, p < 10^?5), but the PCR‐vitro predictions (r > 0.63) all tend to underestimate the K_up measures by mean factors (UF, and p value for testing UF = 1) of 10 (EPA, p < 10^?6), 11 (NIOSH, p < 10^?8), and 6.2 (MH, p = 0.018). For all three PCR‐vitro models, log(UF) correlates negatively with molecular weight (r² = 0.31 to 0.84, p = 0.017 to < 10^?6) but not with log(vapor pressure) as an additional predictor (p > 0.05), so vapor pressure appears not to explain the significant in vivo/PCR‐vitro discrepancy. Until this discrepancy is explained, careful in vivo measures of K_up should be obtained for more chemicals, the expanded in vivo database should be compared to in vitro‐based predictions, and in vivo data should be considered in assessing aqueous dermal exposure and its uncertainty.     

Systems Resilience for Multihazard Environments: Definition,Metrics, and Valuation for Decision Making

The United Nations Office for Disaster Risk Reduction reported that the 2011 natural disasters, including the earthquake and tsunami that struck Japan, resulted in $366 billion in direct damages and 29,782 fatalities worldwide. Storms and floods accounted for up to 70% of the 302 natural disasters worldwide in 2011, with earthquakes producing the greatest number of fatalities. Average annual losses in the United States amount to about $55 billion. Enhancing community and system resilience could lead to massive savings through risk reduction and expeditious recovery. The rational management of such reduction and recovery is facilitated by an appropriate definition of resilience and associated metrics. In this article, a resilience definition is provided that meets a set of requirements with clear relationships to the metrics of the relevant abstract notions of reliability and risk. Those metrics also meet logically consistent requirements drawn from measure theory, and provide a sound basis for the development of effective decision‐making tools for multihazard environments. Improving the resiliency of a system to meet target levels requires the examination of system enhancement alternatives in economic terms, within a decision‐making framework. Relevant decision analysis methods would typically require the examination of resilience based on its valuation by society at large. The article provides methods for valuation and benefit‐cost analysis based on concepts from risk analysis and management.
