中国上市公司信息披露影响因素的实证研究——基于长江三角洲地区上市公司的经验证据

本文基于我国长江三角洲地区200多家上市公司信息披露的经验证据,运用计量分析的方法对影响我国上市公司信息披露的主要内在因素进行了实证研究。研究结果表明:(1)我国上市公司法定性信息披露相对较好,但是自愿性信息披露尤其是战略性信息披露的现状十分令人担忧。(2)上市公司规模对信息披露的影响显著,公司规模越大其信息披露的质量指数越高。(3)上市公司股权结构对信息披露的影响显著,但与经济发达国家或地区上市公司股权结构对信息披露的影响相比显现出不尽相同的特点。其中,国家股集中度对其财务性和战略性信息披露的影响是正向的,而法人股集中度对其财务性和战略性信息披露的影响是负向的。(4)上市公司资本结构和盈利能力对其信息披露的影响显著。其中,资本结构对信息披露的影响是负向的,而盈利能力对信息披露的影响是正向的。     

公司治理对高管报酬的调节效应分析——基于民营上市公司大股东控制、董事会监督的视角

文章以2006年深、沪两市的235家民营上市公司为样本,实证检验了大股东控制、董事会监督对民营上市公司高管报酬的调节效应。实证结果为:我国民营上市公司的公司绩效与高管报酬正相关,董事会监督的调节作用会强化二者正相关关系,但大股东控制的调节作用会扭曲二者的正相关关系。结论表明,在我国民营上市公司的报酬决定中存在"赎买效应"和"任职激励效应",加强对大股东控制的监管,推进董事会独立性的建设,对于提升我国民营上市公司的治理水平具有重要意义。     

Assessment and selection of management consultants: A comparative cognitive study between small- and large-scale companies

This paper explores alternative ways of evaluating and ultimately hiring a generalist consultancy for short- and medium-term projects, and how this is shaped by the size of the clients’ company. What buying factors do managers of small and large firms have in mind when hiring consultants for their projects?Instead of employing surveys incorporating predefined buying factors based on what the researchers think would be important, a cognitive mapping methodology - the repertory grid technique - is applied to investigate the underlying phenomena. Using the repertory grid technique to draw mental models is a novel research technique within the supply management field. Recent behavioral supply chain management research found the behavior of managers to be critically influenced by mental models: the lenses through which managers perceive, simplify and interpret the world.Results show differences between the buying factors used in small- and large-scale companies: managers of large companies are more ‘reputation and outcome-oriented’ and managers of small businesses are more concerned with ‘how the services are rendered’. However, both constituents stressed the importance of expertise, quality and the relationship between the client and the management consultancy, although the character of such a relationship differed between small- and large-scale firms. Results also point out criteria that managers of small and large companies employ to discriminate between good and poor performing consultancies and to judge service delivery. The practical implications for both companies hiring consultancies and the consultancy companies are discussed. For consultancies, our findings can help tailoring their efforts to a differing clientele when marketing and selling their services. For companies hiring consultancies, fixating too much on particular buying factors may lead to biased decisions.     

上市公司资产负债率行业影响的实证研究--对已有研究结论的质疑

文章从行业的角度对沪深A股上市公司的资产负债率进行了较为深入的研究。与国内一些学者的研究结果不同,文章研究发现:(1)行业对资产负债率具有显著影响,但这种影响的力度相当微弱;(2)资产负债率的行业差异并不具有普遍性;(3)同一行业内的资产负债率并不具有相似性,且行业内的差异要大于行业间的差异;(4)上市公司并不存在最优的行业资产负债率;(5)大部分行业的资产负债率与其行业特性不符。     

保险公司偿付能力恶化预测研究

文章在分析公司财务预测研究方法应用前提的基础上,运用MDA模型和Logistic线性回归模型预测方法对我国保险公司偿付能力恶化进行预测研究。结果表明两个主流模型均能在保险公司偿付能力恶化前1~2年较好地进行预测,但是由于两类错估率的不同,MDA模型要优于Logistic模型。     

Wood Fuel or Carbon Sink? Aspects of Forestry in the Climate Question

This paper discusses and contrasts two mainroles of forestry in light of the debate on theglobal climate. As the main problem is relatedto the increases of the CO₂-concentrationin the atmosphere, forests may be viewed aspart of the alleviation of the problem throughtheir function as (i) a source of biomass forenergy production, which may replace fossilfuels and thus indirectly reduceCO₂-emissions, and as (ii) carbon storage,since a growing forest extracts atmosphericCO₂ and fixes it as carbon in biomass. Inthe Scandinavian forestry, logging residues areincreasingly being used for energy production.In this paper the value of forests as a sourceof bioenergy is added to the traditional timbervalue. Formulated as a joint production modelwithin the Faustmann framework, the effect ofthis addition on the optimal rotation length isdiscussed. Based on data for spruce, thedominant species in the Scandinavian forestry,it is demonstrated that the rotation length isshortened compared to the standard Faustmannmodel. Shorter rotation length implies lesscarbon storage. Therefore, in this modelwithout explicit regard to the social carbonstorage value of the forest, the gains in termsof the climate problem from utilisation offorest biomass for energy production are beingdiminished by the value of reduced carbonstorage. The carbon value of the forest is thenadded to complete the model, with the effect ofincreasing the rotation length, a result thatis well known in the literature. Finally, theempirical effects of the interaction of thesetwo climate-related value elements of theforest are discussed.     

Multiple Species Boreal Forests – What Faustmann Missed

Recent research in natural sciences shows that the dynamics in boreal forests are much more complex than what many models traditionally used in forestry economics reflect. This essay analyzes some challenges of accounting for such complexity. It shows that the optimal harvesting strategy for forest owners is history dependent and for some states of the forest, more than one strategy may be optimal.This paper confirms earlier literature on shallow lakes and coral reefs and shows that this kind of phenomena seem much more common than previously thought. They are valid for a wide range of ecosystems that cover large surfaces and they do not depend on the choice of some specific function to model the non-linearity. There are also indications that theses results could be obtained even for resources with concave growth if at least one species with non-linear growth affects their dynamics.     

中国金融控股公司发展模式的新制度经济学分析

论我国上市公司董事会治理结构存在的问题与对策

我国上市公司董事会治理在董事会机构、董事会会议、独立董事、董事会外部制约机制等方面都存在一定问题.解决的对策是:增强董事会的独立性,改变大股东完全控制董事会的局面;加强独立董事制度建设,营造独立董事充分行权的环境;加强对董事的违规处罚力度,强化董事的诚信意识;建立科学合理的董事会考评机制.对于董事会的考核可以从两方面去进行:一方面是对董事会的整体考评,另一方面是对董事个人的考核.我国可以借鉴美国的考核评估方法,由非投资相关者专门针对董事会进行考核评估.     

上市公司管理层薪酬与公司绩效的关系研究--以电子行业为样本

我国上市公司高层管理人员的激励问题一直是各方关注的焦点。本文运用我国电子类上市公司连续三年的经验数据来考察高层管理人员薪酬与公司经营绩效的关系。研究结果表明,我国电子类上市公司高级管理人员的年度货币薪酬与公司经营绩效并不存在显著的正相关关系,与第一大股东是否为国有股也无相关性,但与企业规模存在显著的正相关关系。
