「跨組織資訊系統」(Interorganizational information system; IOS)為不同組織間建立了彼此資料流通的管道，也增強了組織間的合作關係。隨著網際網路(Internet)應用的盛行，使得跨越不同組織界限，甚至穿越國界的資訊交流更加便捷。本研究主要是收集國內外對於跨組織資訊系統採用的相關文獻，建構跨組織資訊系統的採用模式，以臺灣一千大製造業為研究對象，以瞭解現行臺灣製造業在跨組織資訊系統的使用情形，並特別比較不同採用因素（組織、跨組織、環境）對扮演角色（主動促進、被動接受）與採用目的（交易需求、決策支援）的影響及對未採用跨組織資訊系統的原因探討。 經過問卷的設計、預試、修改、發放到回收，總共寄發一千份，回收二百三十一份，回收率23.1%。結果顯示共有42.9%的製造業採用跨組織資訊系統，主要是透過電子資料交換、電子郵件的方式來進行資料交換，其中汽車及零件業的採用比率較高。就採用模式而言，屬於主動促進者與被動接受者的比例相當，而採用目的多為交易需求(63.6%)；權力關係較大、組織策略較著重IOS，及高階主管的支持會影響建置跨組織資訊系統時扮演主動促進者的角色，反之則扮演被動接受者的角色；而依存關係較大則會促使組織在建置跨組織資訊系統時，同時兼具交易需求及決策支援的功能。而在未採用跨組織資訊系統的原因，依重要性順序包括工作流程不重要、不著重IOS投資、不影響市場的競爭性、權力關係不足、無公會推動、信任關係不足、無政府推動、無特定依存關係。 / "Interorganizational Information Systems" (IOS) build the channel for information exchange between different organizations. With the wider applications of the Internet , they make the information flows across the border of the organizations or nations more convenient and fast. To begin with the study, the literature review regarding IOS was conducted to build a conceptual research model. Then the questionnaire was developed, pretested, modified and then mailed. It surveys the managers of information departments of the top 1000 manufacturing companies in Taiwan and reports status of IOS. Two hundreds and thirty-one in this study, giving a response rate of 23.1%. There were 42.9% of these companies which adopt IOS for information exchange, using electronic data interchange (EDI) , electronic mail or extranet. The automobile and accessories industry has higher adoption rate. Among this companies, the proactive companies are nearly equal to the reactive ones, and most companies adopt IOS for transaction processing (63.6%). More power ' the organizational stratgey on IOS with emphasis, and the support of top managers can make companies proactive to adopt the IOS; and more dependent relationship would facilitate companies to adopt IOS for both transaction processing and decision support. The factors for not adopting IOS are that the IOS is unimportant to work, it is not scheduled for investment, it don't affect market competitiveness , the company don't have enough power, the unions never promote the IOS, the partners don't have enough trust, the government don't advocate the IOS, and the partners don't have deeper dependency relationship.
