Component efficient solutions in line-graph games with applications

Recently, applications of cooperative game theory to economic allocation problems have gained popularity. We investigate a class of cooperative games that generalizes some economic applications with a similar structure. These are the so-called line-graph games being cooperative TU-games in which the players are linearly ordered. Examples of situations that can be modeled like this are sequencing situations and water distribution problems. We define four properties with respect to deleting edges that each selects a unique component efficient solution on the class of line-graph games. We interpret these solutions and properties in terms of dividend distributions, and apply them to economic situations. This research has been done while the third author was visiting Tinbergen Institute at the Free University, Amsterdam. The research is part of the Research Programme “Strategic and Cooperative Decision Making” at the Department of Econometrics.

也谈价值、分配等问题--与程恩富、汪桂进两位先生商榷

现实中的价值分配与价值创造相关,主张价值分配与价值创造无关是不正确的;社会主义市场经济中劳动者的资本收入具有劳动收入的性质,以为资本创造价值或者资本收入是非劳收入是不正确的;现阶段的按要素分配只是分配的表现形式,其实质则是按劳分配。     

高技术企业财务报告的改良：价值报告

高技术企业在内在特质、价值体现、价值增值方式等方面与传统企业呈现出差异性，其财务报告改进的重点在于反映企业价值，报告企业如何创造价值以及如何把这些创造价值的活动更有效地与市场进行沟通。高技术企业价值报告应披露有关财务核心能力、无形资产、智力资本、社会责任和价值链等相关信息。     

对马克思按分配原则的反思

马克思的劳动价值论不仅是剩余价值的理论基础和分析资本主义分配的理论依据，同时也是马克思设想的社会主义按劳分配的逻辑起点。只是以往我们对按劳分配原则的最本质的含义理解不够透彻。实质上，应该说马克思设想的按劳分配原则最本质的内容包括三点，即在未来的社会主义社会中，个人消费品的分配以劳动量的大小为依据，等量劳动获取等量报酬，承认能力本位。在社会主义市场经济条件下的按劳分配原则，仍然没有偏离这三点本质的含义，但已经有了新的特点和形式。     

An Empirical Investigation of the Resource-based Antecedents of Customer Value in Turbulent Environments in China

With the increasingly turbulent environment and the significant role of customers in business success, creating and delivering superior customer value by deploying unique competences of a firm has been winning more attention. However, studies of customer value seem rather divergent and fragmented, and few studies, if any, have been conducted to identify the distinctive capabilities that determine the effective and efficient creation and delivery of customer value. This paper tries to bridge such gaps and explores the fundamental antecedents of customer value in turbulent environments in perspective of a resource-based theory. Based on the structural equation models developed, we find that technological competences, integrative competence and strategic flexibility are the key resource-based antecedents of customer value while no evidence is found to support the impact of marketing competences on customer value. Furthermore, only the moderating role of marketing turbulence in the relationship between customer value and strategic flexibility is detected and supported.     

农业产业化经营中利益相关者关系、目标选择与实现方式

本文指出,农业产业化经营的利益相关者是农业价值创造和价值实现的重要影响因素,正确处理好利益相关者关系,有利于保障和提升农业利益,有利于农业价值创造与农业价值实现,这包括农户与龙头企业、政府、中介组织、合作经济组织以及龙头企业与协会之间的关系。农业产业化经营要以产业运作过程商品化、利益分配合理化等方式,实现农业价值创造最大化和农业价值分配最优化的农业产业化目标。     

浅析上市公司股利信息在价值投资中的应用

股票投资价值的灰色多层次评价

股票投资价值的评估是一个多目标、多层次和多因素组成的复杂系统,对其进行综合评价对投资决策是至关重要的。本文根据灰色系统理论,以灰色关联度为测度,提出了股票投资价值的灰色多层次评价模型,并通过实证研究和理论分析,表明该模型对投资者的决策有较高的参考价值。
