The research results suggest that:(1)the factors influence the control of IOR including economic,social and technological factors;(2)the application of interorganizational systems should focus on both technological and non-technological factors;(3)the stronger dependency between organizations, the more effective of the IOS reducing the coordination costs;(4)usually the investment of firms in interorganizational relationship is reciprocal;(5)the appicaton of IT changes the dependency between organizations, which should modify the coordination mechanism, resulting in the change of IOR;(6)the coordination cost affects the effectiveness of coordination among firms;(7) maintaining the interorganizational relationship influences the firms'' network life cycle and matureness;(8)both coordination cost and network size of firms affect sharing mechanisn of the costs and benefits for creating and maintaining interoganizational relationship;(9) the influence of coordination costs to the allocation of super profits deriving from interorganizational relationship is depent on the network topology;(10) the core firm in a network prefer the symmetric network.

我们的研究成果表明：（1）影响管理与控制IOR治理结构的因素有经济因素、社会学因素以及技术因素；（2）在应用组织际信息系统时，要同时关注技术和非技术的影响因素；（3）当组织之间存在较强的依赖关系时，组织际信息系统的应用能够有效减少组织之间的协调成本；当组织之间的依赖关系较弱时，组织际信息系统的应用会加深组织之间被对方侵占的风险，无法显著地减少组织际协调成本；（4）在通常情况下，参与组织际关系的成员的投资是互补的；（5）IT的应用会改变组织间的相互依赖性，组织应调整协调机制，而协调机制的变化会改变IOR；（6）协调成本的大小对协调有效性有着很大影响；（7）组织际关系的维护影响组织网络的生命周期和成熟度；（8）影响组织际关系建立和维护的成本分担和利益共享方案的因素不仅仅跟协调成本有关，而且还与网络规模有关；（9）在对称网络拓扑结构与非对称网络拓扑结构下，协调成本对超额回报分配的影响是不同的；（10）核心企业倾向于选择非对称的网络结构。
