集团公司战略风险管理的理论探讨

本文对集团公司战略管理过程中产生战略风险的机制从公司整体运行的角度进行研究,提出了公司战略风险管理的系统化理论模型,并从公司的环境、资源、能力和公司主题战略四个方面分析了战略风险产生的风险机理。并提出了环境和资源对公司战略主题目标的实现的影响及产生风险的机制。     

A Nonatomic‐Game Approach to Dynamic Pricing under Competition

We study a revenue management problem involving competing firms. We assume the presence of a continuum of infinitesimal firms where no individual firm has any discernable influence over the evolution of the overall market condition. Under this nonatomic‐game approach, the unanimous adoption of an equilibrium pricing policy by all firms will yield a market‐condition process that in turn will elicit the said policy as one of the best individual responses. For both deterministic‐ and stochastic‐demand cases, we show the existence of equilibrium pricing policies that exhibit well‐behaving monotone trends. Our computational study reveals many useful insights, including the fact that only a reasonable number of firms are needed for our approach to produce near‐rational pricing policies.

企业人力资本管理研究

在知识经济时代,企业之间的竞争更多地表现为企业所拥有的人力资本间的竞争。那么,企业怎样才能有效地管理好内部的人力资本呢?本文运用新制度经济学的研究工具,首先从人力资本专用程度、人力资本信息分布状况和人力资本管理的成本与收益三个方面提出了分析框架。然后,按转移成本和对企业依赖程度的不同,把人力资本分为通用性人力资本、专用性人力资本和准专用性人力资本三类,并对每一类人力资本的管理进行了研究。

COMPLEMENTARITIES,MULTIPLICITY, AND SUPPLY INFORMATION

If traders can obtain private information about the payoff and the supply of a stock then there can exist (i) complementarity in information acquisition and (ii) multiple equilibria in the financial and information markets. The additional dimension of supply information increases coordination possibilities in the financial market, leading to multiple equilibria. The existence of two information sources can lead to information acquisition being complementary. The multiplicity of equilibria is suggestive of excess volatility and crashes. The different financial market equilibria imply differing patterns of cost of capital and volume of trade. (JEL: D82, D83, G14)     

组织学习影响组织创造力的知识获取路径研究

为了探明组织学习方式与组织创造力之间的相关关系,基于知识的基础观理论,尝试从外部知识获取的视角出发,探索组织学习方式与组织创造力之间的内在机理,根据市场知识与技术知识信息偏重的不同,构建组织学习方式影响组织创造力的外部知识获取路径.采用问卷调查收集275个有效的企业样本,运用结构方程模型方法对样本数据进行统计分析.研究结果表明,探索式学习通过影响市场知识获取进而推动技术知识获取,最终影响组织创造力的作用路径,利用式学习则主要通过对技术知识获取的促进影响组织创造力,技术知识和市场知识获取在组织学习影响组织创造力过程中扮演不同的中介角色,探索式学习能更有效地推动外部知识获取,从而对组织创造力产生影响.     

Note on inventory models with Weibull distribution deterioration

This article explores the inventory model with a general demand rate function in which both the Weibull distributed deterioration and partial backlogging are considered. The inventory model discussed here is based on the important finding by Wu [Wu, K.S., 2001. An EOQ inventory model for items with Weibull distribution deterioration, ramp type demand rate and partial backlogging. Production Planning and Control, 12, 787–793]. There are four parts in our research. First, we derive the analytical framework of the inventory model for a general demand rate function1 1.?Based on detailed suggestions of Professor Wafik H. Iskander, Email: whiskander@mail.wvu.edu . Second, for the ramp type demand, we improve Wu's model to find the criterion to guarantee the existence and uniqueness of the optimal solution. Third, we develop a new model to compensate for the missing case in Wu's article. Fourth, we combine our results to show that our findings are applicable to the ramp type demand inventory model, so that the optimal solution is independent of the demand function. Finally, some numerical examples and graphs are provided to illustrate our discovery and demonstrate the application of our analytical framework.     

初始资源、社会资本与创业行动效率——基于资源匹配视角的研究

创业者所拥有的初始资源基础及其可利用的社会资本对于新企业绩效的重要作用已被广泛证实,但对于二者在创业行动层面的角色尚缺乏深入探索.基于此,本文从关系强度与关系资源的角度考量社会资本,考察了初始资源、关系强度和关系资源与创业行动效率间的关系,以及资源获取匹配度对该作用过程的调节作用.结果显示,在创业过程中,拥有充裕的初始资源,能够利用丰富的社会资本的创业者更易于快速采取创业行动,促进新企业生成.当创业者利用关系资源获取与初始资源相匹配的资源时,关系资源促进创业行动效率的作用更为显著.本文的理论贡献在于深入行动效率挖掘初始资源与社会资本改善创业行动效率的作用机制,从资源匹配的视角剖析社会资本的作用机理,研究发现,社会资本作用的发挥源于其为创业者所提供资源的匹配效果,而非其自身的存量特征,这是解释创业行动效率差异的一个重要原因.     

A new two-party bargaining mechanism

If resources and facilities from different partners need to be engaged for a large-scale project with a huge number of tasks, any of which is indivisible, decision on the number of tasks assigned to any collaborating partner often requires a certain amount of coordination and bargaining among these partners so that the ultimate task allocation can be accepted by any partner in a business union for the project. In the current global financial crisis, such cases may appear frequently. In this paper, we first investigate the behavior of such a discrete bargaining model often faced by service-based organizations. In particular, we address the general situation of two partners, where the finite Pareto efficient (profit allocation) set does not possess any convenient assumption for deriving a bargaining solution, namely a final profit allocation (corresponding to a task assignment) acceptable to both partners. We show that it is not appropriate for our discrete bargaining model to offer the union only one profit allocation. Modifying the original optimization problem used to derive the Nash Bargaining Solution (NBS), we develop a bargaining mechanism and define a related bargaining solution set to fulfil one type of needs on balance between profit-earning efficiency and profit-earning fairness. We then show that our mechanism can also suit both Nash’s original concave bargaining model and its continuous extension without the concavity of Pareto efficient frontier on profit allocation.
