以制造商和供应商为视角,考虑网络外部性特性,研究组织际信息系统(Interorganizational information systems,IOS)的动态协调关系与策略.设定网络外部性的离散动态属性,引入吸引机制与竞争机制控制向量,给出网络外部性动态最优控制算法与命题;进而构建制造商对供应商有无补贴政策情形下的收益模型,并模拟正负网络外部性、制造商与供应商收益、供应商加入IOS数量的演化轨迹,从而得出组织际信息系统在协调制造商与供应商收益上的动态规律.研究认为:补贴政策可以在IOS的初始阶段实施,但此时注重实施效率;补贴政策在第二三阶段实施,此时竞争机制作用明显,应注重补贴政策的动态与差异性.
The paper introduces the business-based interorganizational information platform(IOP) and analyzes the feasibility and mechanism of business-based IOP governing global supply chains vulnerability,and then aims to develop a risk evaluation software under reliable algorithm to appraise the capability of an interorganizational information platform resisting to global supply chains risks that supports platform users and providers to make decisions.The paper respectively starts with a basic conceptual model of global supply chains vulnerability and a conceptual model of global supply chains vulnerability in business-based IOP,and then gives the simulation model of governance of global supply chain vulnerability in business-based IOP;then has a discussion with the beneficial model of governing global supply chains vulnerability by using business-based IOP or not.The results of research:(1) If given the ratio of expense per income on global supply chains using business-based IOP, we can estimate the costs to take precautions against risks that decides to the maximum value of the average income of per transaction on global supply chains using business-based IOP.(2) If given total income of transaction on global supply chains using business-based IOP,we can estimate the maximum value of the ratio of expense per income on global supply chains using business-based IOP, which would help to make pricing policy for IOP service provider.
论文以网络拓扑结构概念应用于组织际信息系统(interorganizational information systems,IOS)的管理运作研究上,研究了组织际信息系统结构的拓扑类型,提出结构成本概念,构建了IOS运营成本模型,对不同拓扑结构所对应的运营成本进行量化与比较、优化,并进一步基于结构成本的组织际信息系统拓扑结构与产业类型匹配问题展开应用研究。结果表明企业维护其IOS在产业链中具有竞争优势的位置而支付的费用会带来其与产业链其他企业的交易成本减少,同样的企业为了追求更具优势的IOS结构位置而支付的费用也会带来企业的交易成本减少。论文的贡献:一方面,结构成本概念引入IOS拓扑结构时可分析IOS各拓扑结构的成本优势,对企业加入或构建何种结构形式的IOS具有重要指导意义,进而扩展到产业上的应用;另一方面,对组织际信息系统的理论依据做出一定的调整,扩充了现有理论体系。
