【摘要】：为了研究区域航空物流网络空间结构特征及优化布局问题,在关系数据的基础上,采用社会网络分析(Social Network Analysis,SNA)方法,构建了一种针对有向多值型网络空间结构的量化分析体系。运用核心边缘结构、凝聚子群、伯特结构洞以及拓扑分析模型,选取核心度、边关联度、限制度、等级度和冗余度5个定量指标从分布特征、群聚特征、连接机制和凝聚性4个角度对云南省航空物流网络的空间结构特征进行了描述和分析。结果显示:云南省航空物流网络以昆明为核心呈中心发散的状态,西双版纳、丽江和大理形成的次级区域对中心节点昆明的依赖性过高;昆明、西双版纳、大理及丽江间的连接稳定性、密集性强度较高,网络内部空间组织分化比较明显;核心区与密集区集中于旅游热点区域,空间布局较少兼顾与产业布局和跨境口岸之间的衔接。最后结合指标测算分析结果和云南省过境物流、东盟贸易的需求,充分利用现有交通资源,提出以昆明-西双版纳为"双核"的"双环形航空走廊"网络的空间布局优化建议。
[Abstract]:In order to study the spatial structure of regional aviation logistics network and optimize the layout, based on the relational data, the social network is used to analyze the social Network Analysis. In this paper, a quantitative analysis system for directed multi-valued network spatial structure is constructed by using the SNA-method. The kernel degree is selected by using the core edge structure, condensed subgroup, Burt structure hole and topological analysis model. The quantitative indexes of edge correlation degree, limit system, grade degree and redundancy degree were analyzed from the distribution characteristics and clustering characteristics. The spatial structure characteristics of Yunnan aviation logistics network are described and analyzed from four angles of connection mechanism and cohesion. The results show that Kunming is the core of Yunnan aviation logistics network. The secondary regions formed in Xishuangbanna, Lijiang and Dali are too dependent on Kunming. The connection stability between Kunming, Xishuangbanna, Dali and Lijiang is relatively high, the density intensity is high, and the spatial organization differentiation is obvious; The core area and the dense area are concentrated in the tourist hot spot area, and the spatial layout seldom takes into account the connection with the industrial layout and the cross-border port. Finally, combining with the result of the calculation and analysis of the index and the demand of the transit logistics and ASEAN trade in Yunnan Province. Making full use of the existing traffic resources, the paper puts forward the space layout optimization proposal of the "double ring air corridor" network with Kunming-Xishuangbanna as the "double core".
