程式碼是構成網際空間最基本的核心，也是行使網際權力的基礎；誰能決定程式碼的設計、分配與管理，誰就能稱霸網際空間。美國最先發展網際網路，故在網際網路普及全球前，程式碼的設計、分配與管理是由美國獨佔，但也在1990年代中期後，引起歐洲各國、日本和中共等的挑戰。 本文從歷史的角度出發，探索美國網際霸權形成的政經背景與過程，特別是其利用程式碼的控制和各種經貿政策，而獨霸整個網路世界和資訊產業。美國政府如何善用美國的政經優勢及其企業的實力，而將網際網路空間的整體架構，導向對美國政府與企業都有利的方向，將是本文的焦點；其中，涉及他國政府的權力與利益分配、競爭模式，也是本文將觸及的範圍。

The whole cyberspace is composed of code, which is also the core of cyber-power; who decides the design, distribution, and management of the codes, will also dominate in the cyberspace. Before the World Wide Web pervaded all over the world, the cyber-power was controlled by the United States due to historical reasons, but it has brought forth the challenges of Europe, Japan and China since the mid-1990’s. By tracing back to the history, this article tends to analyze ‘why’ and ‘how’ the US can have owned her super power in the cyberspace and in the IT industry. Besides various kinds of economic and trade policies, the government and companies of the United States cooperated to dominate code and form the structure of the cyberspace. This analysis will be the most important part in the article; in addition, the modes of competition and the challenges from other nations will also be discussed in this thesis.
