数字化时代,网络空间成为大国博弈必争要地,中美在网络空间的权力竞争尤其激烈。网络权力来源于传统权力,但也与传统权力存有差异性。现有关于中美网络权力竞争的研究主要有实力挑战论、网络霸权论与网络资源获取论,鲜有将美国作为网络权力主体,分析其对华网络权力认知变化与行为表达的关系。美国处在网络权力中心地位,是网络权力博弈的发起者,也是感知网络权力影响的主体;中国则属于后发国家,是需要发展网络实力的主体,也是影响美国网络权力的主体。本文基于中国“网络权力发展”与美国“感知网络影响”的互动框架,将中美网络权力博弈分为四种类型:一是强技术发展、强影响感知:多维度制衡,烈度高型;二是弱技术发展、强影响感知:单维度制衡,烈度高型;三是强技术发展、弱影响感知:多维度制衡,烈度低型;四是弱技术发展、弱影响感知:单维度制衡,烈度低型。本文分别对以上四种类型予以案例论证。以上中美两国网络权力的博弈模式将处于动态变化之中,并在一定条件下可发生转换。
