Abstract: This article analyses the aspect of interorganizational information systems(IOS)applied to management and operation in the sense of network topological structure. It firstly proposes the concept of structure cost, and then builds the cost model of IOS. It quantifies and compares the corresponding structure cost of different IOS topologies by programming model, and further studies the applied problem of fitness with industry type and IOS topology based on structure cost and other related issues. The results show that firmly maintaining its competitive IOS structure location in the supply chain to pay will reduce transaction costs with other firms and similarly, firmly pursuing its more competitive IOS structure location in the supply chain to pay will reduce transaction costs with others. On the one hand, the structure cost being introduced can analyse the cost advantages of kinds of topologies of IOS better, and has an important impact on what topology of IOS to organization joins and builds, and thenis extended to the industry. Also, this paper contributes to expanding the theoretical system of IOS.

Key words: IOS, industrial chain boundary, topological structure, transaction costs, structure cost, fitness

摘要： 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。
