全面推进相关制度创设、力量创建和技术创新，试图在塑造全球网络空间新格局进程中抢占有利位置。放眼未来，网络空间国际战略竞争影响深远，堪比19世纪的海洋竞争、20世纪50年代的核竞争和80年代的空间竞争，将在很大程度上决定着21世纪国际战略力量的消长和大国的兴衰。
围绕全球网络空间主导权的争夺持续升温
美国把网络空间视为21世纪必须重点掌控的全球新兴公域，借以维护和巩固美国的全球霸权。2011年5月，白宫发布首份关于全球网络空间建设的纲领性文件——《网络空间国际战略》，提出建设未来网络空间的总体目标，即“建立一个开放、共享、安全和可靠的网络世界，以支持国际商业贸易，加强全球安全，促进***和技术创新”;提出尊重基本自由，尊重知识产权，保护互联
