摘　　要：知识主体之间的各种知识共享活动日益频繁,使得知识网络在演化中出现了知识流动的小世界现象。少数占据外在比较优势的知识主体逐渐演化为知识网络的核心,产生了主体和知识的区域性集聚。针对当前知识网络中存在的"均衡发展陷阱"和"流动性陷阱"问题,本文提出现实知识网络中存在的关键点-专业化发展成本和知识流动成本的计算。本文引入经济学中的内生比较优势理论,建立基于比较优势策略下自主演化的知识模型,借助基于度与集聚系数的节点重要性评价方法,分析比较优势策略对知识网络的影响规律,从而为优化知识网络结构提供数量分析基础。The knowledge sharing activities become more and more frequent. The small world phenomenon of knowledge flow has emerged in the evolution of knowledge network. A minority of knowledge agents, which have the advantage of exter- nal comparison, have evolved into the core center of knowledge network. The regional agglomeration of subject and knowl- edge has been produced. Focusing on the current issues of ＂balanced development trap＂ and ＂liquidity trap＂ existed in the knowledge networks are raised. The paper proposes that the key point of problem in real knowledge network is the Calcula- tion of the cost of specialization development and knowledge flow costs. Theory of Endogenous Comparative Advantage in e- conomics is introduced to build a Knowledge model of autonomous evolution based on comparative advantage strategy. By mean of a node importance measurement based on the degree and clustering coefficient information, we analyze of the impact of comparative advantage strategy on knowledge network, which provide a basis for quantitative analysis to optimize the knowledge network structure.
