摘　　要：本文通过信息元概念发现信息两重性及互联网的市场特征,由此揭示和证明,网络经济存在内生的市场非出清和外部效应,网络统一信息两重性而使信息流与物流统一,网络外部性通过复制、共享与合作而内部化,产生网络信息聚合—协同效应,创造超越传统规模经济概念的社会效益与资源配置效率,经济活动不再遵循一般均衡分析。基于信息元概念和网络信息池原理,本文构建效用不完全转移的动态合作博弈模型及其拓展模型,研究网络经济市场结构与行为特征,破解信息不对称和网络外部性等基本问题,对著名的"摩尔定律"等经典理论作出修正,对现代网络经济学和信息经济学的理论研究和实际应用,都是重要进展。借此本文也指出,互联网使实体经济与虚拟经济统一,主流经济理论的信息两分法需要改变。This paper firstly discovers information duality and the market characteristics of internet economy at home and abroad through the concepts of information-elements, so then reveals and proves that the network economy have the endogenously non-clearing market and external effect; internet can unified information duality to make the information flow and physical distribution unified; network externalities can be internalized by copying, sharing and cooperation, so that it can generate network aggregation--synergy effect and create social benefits and efficiency of resources allocation beyond the traditional economy of scale. Economic activity is no longer follow the general equilibrium analysis. Based on information- elements and the principles of network information pool, this paper builds dynamic cooperative game model whose utihty is incomplete transferred and its extended models, studies the market structure and behavior characteristics of network economy, and solves the information asymmetry and network externalities and other major issues. Our work makes a huge revision for famous ＂Moore＇s law＂ and other classic theory, and becomes the significant progress and breakthrough for theory research and practical application in fields of modern network economics and information economics. In addition, this article also points out that the internet has made the real economy and virtual economy unified, and information dichotomy of mainstream economic theory needs to change.
