Abstract: Improvement of regional transportation is the basis and necessary condition of tourism industry agglomeration.Traditional economic geography and new economic geography and their integration provide a certain research paradigm for studying the relationship between regional transportation development and tourism industry agglomeration.So far six remarkable tourism industry agglomeration areas have been developed on the transportation network nodes in Wuling Mountain area,including Zhangjiajie,Huaihua,Fenghuang-Jishou-Yongshun,Enshi,Qianjiang-Wulong,and Tongren.This can be explained from the agglomeration mechanism and response path of tourism industry.First,development of regional transportation has an impact on the location and resource endowment as a source regional factor in the traditional economic geography analysis framework,resulting in the initial tourism industry agglomeration;then,the spatial-temporal distance and perceptual distance are further compressed,affecting money externalities,technological externalities and spatial costs in the new economic geography analysis framework and deeply improving regional tourism industry agglomeration.Relying on transportation hubs,we should build a dimensional and hierarchical transportation network in the future and carry out a unified,barrier-free,and traffic-oriented policy,so as to improve the quality and efficiency and realize sustainable development in tourism industry agglomeration.

Key words: regional transportation, tourism industry agglomeration, traditional economic geography, new economic geography, Wuling Mountain area
