網際網路是一個全球性的資訊科技應用新趨勢，其所代表的不僅是一項新的資訊應用形式，也是一種正在快速形成的新文化與新生活方式。商業現代化是提昇國家經濟競爭力與國人生活品質必經途徑，經過幾年的推動之後，在若干作業的自動化方面雖已有些許進展，但距更先進國家已達到的境界仍有一大段距離，更何況先進國家對於資訊科技的認識與應用正以較前更為積極的步調往前邁進，除非我國在資訊科技觀念及認知上有所突破，並化為具體的行動急起直追，否則這個差距豈祇是無法拉近而已！本文討論的主題包括：受到網際網路所衝擊的資訊經濟、網際網路科技的企業內部應用（intranet）與企業外部應用（extranet），特別強調企業營造未來導向的策略觀的重要性，以及企業內部網路在組織文化方面可以扮演的角色，期能為提昇商業現代化的廣度與縱深提供若干觀念上的指引。

　　　　　As a newly emerging trend in information technology (IT) applications, Internet not only represents a different form of IT application, but also a rapidly forming, new culture and new life style. In the meantime, commerce modernization is considered a critical measure leading to enhanced national economic competitiveness and improved life quality. After several years'development and active promotion, most progression in this area still tends to focus on automation of transactions processing, lagging far behind the situation in more progressive countries. Since those countries are continuing to pursue even more sophisticated utilization of IT, we are facing a real possibility of lagging even more behind, unless we do something about it. There needs to be a dramatic breakthrough in both perception and understanding, based on which major actions may be devised and implemented. This conceptual article discusses the new economics of information under Internet's impact, innovative applications of intranets and extranets, a future-oriented perspective of strategy, and the role of intranets in nurturing organiztional culture. The suggestions presented herein may provide some guidance for the further progression of the commerce modernization effort.
