中文摘要：

基于百强旅行社获取的旅游线路报价单，以四川省和重庆市为案例地，借助社会网络分析理论，探讨四川省旅游网络的特征及各旅游节点的角色地位，以期为四川省目的地差异化联合营销，均衡发展提供参考。结果表明：（1）四川省旅游网络结构发展不均衡，整体的密度较低（0.42），反映各节点间的联系还不密切。（2）在整体网络中，程度中心势为51.8%，中介中心性为41.64%，外向和内向接近中心势分别为63.48%、61.95%，较高的程度中心势与接近中心势、较低的中介中心势表明核心-边缘结构的存在，成都、绵阳、南充、阿坝州、甘孜州处于核心位置，广元、乐山、宜宾、雅安、重庆处于边缘位置。（3）在个体网络中，各节点规模、效率等差异较为明显，成都的规模最大、关系最多，同时结构洞优势最明显。

英文摘要：

Based on the statistical analysis of collected data from travel agency,this paper discusses the characteristics of tourism network and tourism nodes’role status in Sichuan tourist net by social network analysis theory.The purpose is to provide refer-ences for differential joint marketing and balanced development.The results show that the structure of Sichuan tourist net is un-balanced.Its overall density is 0.42,which shows that the contacts of tourism nodes is not close.Besides,in the whole net,its centralization is 51.8%,its betweenness is 41.64%,its incloseness and outcloseness is 63.48% and 61.94% respectively.The higher centralization and closeness and the lower betweenness indicate that the network exists the structure of core/periphery. Chengdu,Mianyang,Nanchong,A’ba and Ganzi are located in the core position and Guangyuan,Leshan,Yibin,Ya’an, Chongqing are in the edge position.Finally,in the ego net,there were significant differences in size and efficiency of each nodes, Chengdu owns the largest size and the most ties,meanwhile owns the most obvious advantage of structural hole.
