航线网络连接驱动因素分析

民航运输是国家综合运输系统的主要部分，其能够增强区域间的连接性，推动区域社会经济的发展。因此研究民航航线网络连通性的驱动因素具有现实意义。首先以内蒙古自治区为研究对象，运用社会网络分析法对航线网络连通性进行评价。其次采用最小二乘法和地理加权回归方法，分析航线网络连通性的驱动因素。结果表明，第三产业增加值、居民可支配收入、旅游人数和政府规划等级等因素对内蒙古自治区内航线网络连通性具有显著的驱动性，且相应的驱动因素存在明显的空间分布特性。研究结果对加强内蒙古自治区内航线网络的连通性具有实际意义。

Analysis on driving force of airline network connectivity

As an important component of national integrated transport system, civil aviation transportation is able to effectively promote regional connectivity and social economic development. Therefore, it is of great practical significance to study the driving factors of civil aviation airline network connectivity. First, the airline network connectivity was evaluated by social network analysis method in Inner Mongolia Autonomous Region. Then, the least square method and the geographically weighted regression method were applied to demonstrate the driving factors of airline network connectivity. Results show that factors including the additional value of the tertiary industry, the disposable income of residents, the number of tourists and the government planning level have significant promotion on the connectivity of regional airline network. Meanwhile, these driving factors also have notable spatial distribution characteristics. Results are of practical significance for strengthening the connectivity of the airline network within the Inner Mongolia Autonomous Region.
