The Dynamics of Capital Structure in Transition Economies

This paper uses a dynamic unrestricted capital structure model to examine the determinants of the private companies' target financial leverage and the speed of adjustment to it in two transition economies, the Czech Republic and Bulgaria. We explicitly model the adjustment of companies' leverage to a target leverage, and this target leverage is itself explained by a set of factors. The panel data methodology combines cross-section and time-series information. The results indicate that the Bulgarian corporate credit markets were less supply -constrained than those of the Czech Republic during the period under investigation. Bulgariancompanies adjusted much faster to the target leverage than Czech firms. The speed ofadjustment related positively to the distance between target and observed ratio for Bulgarian companies while the relationship was neutral for Czech companies. The conservative policies of Czech banks and the exposure control were likely responsible for the slower adjustment among the larger companies while the opposite were true for Bulgarian banks and companies.     

The Dynamic Production Axioms and System Dynamics Behaviors: The Foundation for Future Integration

Realistically, organizational and/or system performance is dynamic and non-linear. However, in the efficiency literature, system performance is frequently evaluated considering linear combinations of the input/output variables and without explicitly taking into account the causes of efficiency behavior nor the dynamic behavior of systems. Policy decisions based on these results may be sub-optimized because the non-linear relationships among variables, causal relationships, and feedback mechanisms are ignored.This research takes the initial step of evaluating system performance in a dynamic environment, by relating the factors that effect system performance to the policies that govern it. To accomplish this, this paper extends the concepts of the static production axioms into a dynamic realm, where inputs are not instantaneously converted into outputs. The relationships of these new dynamic production axioms to the basic behaviors associated with system dynamics structures are explored.     

模糊聚类分析在配送中心订货策略中的应用

针对传统ABC分类方法的局限性,提出了面向订货策略的物料模糊聚类分析方法,以物料订货量和物料单价作为聚类指标,对物料进行模糊聚类分析,对于不同类别的物料实施不同的订货策略。给出了一个模糊聚类应用于订货策略的实例,并与基于ABC分类的库存控制系统进行了对比,表明基于多因素模糊聚类的库存控制系统能有效降低库存成本。

企业生态群落和“大”动态能力战略观

战略管理的核心作用是把环境的机会和企业的力量相匹配，同时保护企业的弱点使之不受环境的威胁。目前的企业能力理论过多地把其战略目光放在了企业内部。然而，竞争日益全球化的今天，企业的竞争，其实质不再仅仅是单纯意义上的企业能力与企业能力的较量，而是企业所属的生态群落能力间的较量。为此，本文从全球化竞争的视角出发，阐释了企业生态群落中政府动态能力、企业动态能力、金融制度动态能力、教育制度动态能力的内涵，探讨了政府动态能力、企业动态能力、金融制度动态能力、教育制度动态能力间互动作用机理，在此基础上提出了“大”动态能力企业战略观。
