The purpose of this paper is to identify the degree to which the marketing discipline has hitherto engaged with business model literature. The results of a systematic review of business model literature are presented and utilise both the citation counts and the h-index to objectively demonstrate the limited engagement that the marketing discipline has had with business model literature, and the limited degree that the discipline has influenced that literature. The key findings reveal a growing, but formative body of literature that, hitherto, has been dominated by non-marketing disciplines and which has only just begun to be addressed by present day marketing scholars. Using the most influential articles identified in the analysis, the paper concludes with a case for the empirical development of the business model concept with industrial marketing scholarship. Such development is argued to be grounded in the potential of open business models, co-created with multiple stakeholders in a supply chain and the end users of a value proposition.  相似文献

Traditional models of economic development such as economic base and urban revitalization models have been found wanting. Both models rely on expert-based assessments of local development needs. More recent approaches call for a stronger focus on local development needs and resident skills as the basis for designing development strategies. One such neighborhood-based approach to development is presented in this paper. Its initial step was a survey of 444 households representing 1398 residents conducted in the Hamilton Hill and Vale neighborhoods of Schenectady, New York a 'downsized' community of about 65,000 residents in the Capital District of New York State. Survey results show a strong need for recreation, childcare, a grocery store, care for the elderly and home repairs. Residents' self-assessed job skills and interests appear to be well suited to meet these needs. Yet despite these promising results, barriers to neighborhood-based development persist. These barriers reiterate the long history of isolation prevalent in US inner city neighborhoods. Two issues are particularly characteristic of the barriers that continue to keep urban neighborhoods isolated from their larger context. They are: (1) a lack of effective communication between local residents and decision makers; and (2) a lack of valuation systems that properly assess the value of social and environmental context and their contributions to local development.  相似文献

This paper focuses on exploring the potential and empirically observable value creation of strategic foresight activities in firms. We first review the literature on strategic foresight, innovation management and strategic management in order to identify the potential value contributions. We use survey data from 77 large multinational firms to assess how much value is generated from formalized strategic foresight practices in these firms. We show that it is possible to capture value through (1) an enhanced capacity to perceive change, (2) an enhanced capacity to interpret and respond to change, (3) influencing other actors, (4) and through an enhanced capacity for organizational learning.  相似文献

This paper investigates how an abandonment option influences the optimal timing of information in a sequential adverse selection capital budgeting model. While the divisional manager has imperfect private pre-contract information, headquarters can time whether the manager obtains perfect project information before (timely information) or after (delayed information) the contract is signed. In the absence of the abandonment option, headquarters favors timely (delayed) information if the investment costs are high (low). The presence of the abandonment option favors delayed information because under the timely information regime the value of the abandonment option is zero, whereas under the delayed information regime the value of the option is positive.  相似文献

次贷风波所引起的金融危机不但使国际银行业一度岌岌可危,而且沉重打击了世界经济。作为市场风险管理的核心,Vag模型遭到各方诟病。通过分析《高盛风险之海市蜃楼》一文,本文归纳了对Vag模型的几点认识误区,包括忽略对外部数据准确性的考核与检验,在模型应用上未能对正常市场情况与极端市场情况区别对待等。本文进而论证Vag仍是当前风险管理的首选工具,提出对收益率概率密度分布的选择将是Vag模型进一步发展的核心与关键,强调数据分析,指出量化研究应作为主观判断的前提与基础等观点。  相似文献

英国是PFI/PPP模式的发起者和主要推广者。采用了PSC指标为基准的评价方法来获得最佳的VFM。本文研究表明:PSC指标的应用随着PPP项目在全球的开展并不具有广泛意义,分别受到来自实践和理论的质疑。这对建立我国的VFM评价体系有一定启示作用。  相似文献

随着各种项目管理体制和方法的全面转型,我国需要借鉴和运用国际通行的项目挣值管理(EVM)绩效评估方法。然而,现有EVM绩效评估方法中存在着将实际多个项目要素影响简化为项目成本和进度两要素造成的绩效评估失真和信息缺失的实际问题与理论缺陷。本文将全面讨论现有的EVM方法,并给出有关解决方案及实务验证。  相似文献

本文以中央企业上市公司为样本,讨论国有企业环境责任与公司价值之间的关系。文章在控制公司规模、行业竞争力等变量的条件下,回归结果发现:中央企业上市公司环境责任与公司价值之间存在正相关关系,但不显著。因此,很难认为公司承担更多环境责任能够促进公司价值的增长。  相似文献
