The internationalisation from a network perspective: A longitudinal study

This article explores a range of internationalisation options in terms of their adequacy in explaining the patterns of internationalisation undertaken by contemporary organizations. It is argued that there is a life cycle in the internationalisation of firms and that existing explanations of internationalisation cater for some, but not all, elements in this life cycle. The paper then outlines a longitudinal study of the internationalisation of an Australian firm from its early tentative involvement via export in the 1960's to its acquisition by an overseas firm in 2000. This study shows that network embeddedness appears to offer the most comprehensive explanation for the international life cycle of contemporary organizations.     

演化经济学的两种系统观

演化经济学在系统处理方法上呈现出两种不同的主张,一种是以复杂适应系统理论为导向的演化建模分析方法,而另一种则强调多层级本体论和涌现观,并对复杂系统建模持抵制态度,尽管在反对主流经济学微观还原论这一点上两者取得了一致,但建立在相似性理论基础上的复杂系统建模更适合对复杂性存在的描述,而强调比较的、历史的和阐释的多层级本体论和涌现观的系统分析方法则更接近经验事实。     

Study based on ＂Situational Rationality＂ hypothesis for customer market classification model

The traditional market segmentation was based on ＂transcendental rationality＂ or ＂Situational Rationality＂, studies shows that it had disadvantages. This paper states the ＂Situational＂ integrated rationality hypothesis and then comes up with the market segmenting models and classification algorithm basing on this hypothesis. This algorithm combined the Rough Set theory and Neural Networks in application, which overcome the dilemma that caused complicated network structure and long training time by only using Neural Networks and influenced the classification precision caused by noise disturbance by only using Rough Set methods. Finally, the paper did a comparison experiment between the traditional method and the method we came up, the results shows that the model and algorithm has its advantage on every aspects.     

Applying agent-based modeling to the evolution of eco-industrial systems

Agent-based modeling is simply a modeling technique for describing complex adaptive systems in a form that can be solved by computers. In this paper, agent-based modeling is applied to eco-industrial systems to gain new insights into their behavior. The factory in the eco-industrial systems is taken as an agent, and the objects, attributes and behaviors are determined. Some important interaction mechanisms between agents are also designed. Besides, the sustainability evolution is also studied through emergy theory. More importantly, a new concept, the Internal-flow emergy, is used to indicate the evolution direction of an eco-industrial system. Finally, a hypothetical eco-industrial park utilizing natural gas and halite as the main raw material inputs is adopted as a case study to illustrate the effectiveness of the agent-based modeling.     

Returns from social capital in open source software networks

Open Source Software projects base their operation on a collaborative structure for knowledge exchange in the form of provision or reception of information, expertise and feedback on the creation of source code. Here, we address the direction of these knowledge flows among projects throughout social networks and their impact on project success. We identify the roles of membership or contribution that individuals play within projects. We found that connections through contributors who bring their knowledge to the project, improve project success, and that connection through members, who transfer their knowledge towards other projects, enhance project success. Finally, we found that ties through shared membership and contributions hamper project success. The analysis of knowledge flows and their impact on project success imply a translation of returns from investment in social capital, where investment takes the shape of knowledge flows and the returns mean the projects’ diffusion over the network.

改进的ＢＡ无标度网络模型在企业集群中的应用

各组成元素间的网络关系是企业集群的本质特征,其总体竞争力与其内部网络具有紧密联系。运用复杂网络理论研究了企业集群的无标度网络特征,并运用改进的无标度网络模型来定量分析集群网络中各构成要素的重要性,为集群向既定目标发展提供了控制依据。     

知识网络中的社会资本及其作用

知识网络的绩效,在一定程度上取决于网络伙伴间社会资本与信任关系的形成。社会资本在知识网络中起着不可忽视的重要作用,其积极作用主要有:促进组织间交互学习;减少交易费用;促进风险分担;形成知识网络的竞争优势,进而增强网络成员的竞争优势;有利于解决知识网络中产生的"囚徒困境"等问题。而其消极作用主要有:易帮派化;易冒进;易产生锁定。     

基于随机过程理论的复杂可修系统可靠性规律研究

利用随机过程理论研究了复杂可修系统的可靠性规律,用随机过程模型中的Ｗｅｉｂｕｌｌ过程来描述复杂可修系统的可靠性规律。用Ｍｏｎｔｅ Ｃａｒｌｏ方法模拟验证了Ｗｅｉｂｕｌｌ过程模型的参数估计公式。其中参数β的最大似然估计误差低于２％,λ的最大似然估计误差低于７％。两组试验数据的处理结果表明Ｗｅｉｂｕｌｌ过程模型有较高的拟合精度。     

Indivisible labor implies chaos

Summary. We study a simple infinite horizon model with indivisible labor. We characterize the optimal plans under the assumptions that and that , where R is the gross interest rate and is the discount factor. We show that under those assumptions, optimal plans are almost always asymptotically nonperiodic unless initial wealth is excessively small or large.

中国与东亚和美国贸易差额联动效应分析

中国对东亚国家（地区）的贸易长期处于逆差状态,而同时对美国却保持高额顺差。本文通过实证分析认为,中国对东亚的贸易逆差及对美国的贸易顺差之间存在联动效应,并从雁行模式的东亚产业转移、东亚生产网络及美国需求三方面分析了该联动效应产生的原因。还探讨了差额联动的变化趋势：长期看,由于中国在三角贸易中的地位将有所改变,差额联动效应有望减弱;短期看,差额联动效应仍将存在。

Abstract：

China has always been keeping trade deficit with East Asia,but keeping trade sur-plus with America at the same time.The paper proves a coupling effect between the trade surplus and deficit by positive analysis,and analyses the reason why a coupling effect can exist from three aspects：East Asian industrial transfer in flying geese model,East Asian production net-works and American demand.The paper also discusses the trend of coupling effect：in the long run,the effect is expected to reduce since the position of China in triangular trade pattern will be changed;in the short term,the effect will still exist.
