摘　　要：对中国产业集群网论坛用户提问与回答的关系数据,建立了一个以自我中心,包括832个用户的知识传播网络模型。将该传播网络的传播模型与Watts通过Email方式建立的信息传递网络模型相比较。结合经典的传染模型和渗流模型及这两种信息传播网络的特点给出了相应的传播模型。不同的传播模型有不同的提高信息传播广度的方法:基于社会网络的信息传播不仅要提高信息传递者的激情而且要提高社会网的连通性,基于论坛回复关系的信息传播网络只需提高用户的回复激情就可扩大信息传播的广度。同时还给出了两种方式的难易程度,根据难易程度建议依据信息的不同性质在不同的网络中进行传播。Base on the relation data of question and answer on the forum of China enterprise clusters ,we construct a network model of knowledge transferred which consists of 832 users and egos Wang Ji - ci . Compare with Watts＇ s information dissemination network, which is through e - mail. The article also gave respectively diffusion model which combine the classic epidemic and percolation model and the eharaeteristie of the two information transferred networks. Different networks has different method of improving extent of information spread： we improve not only the incentive of information passer but also the connectedness of network on the social networks ; we only improve the incentive of answer that build upon the forum networks. Meantime , the article gave the grade of the two manner and suggested that we ean utilize the different networks to spread the different information.
