网络关系视角下中国公民出境旅游安全感知事件时空分布特征——以"一带一路"沿线国家为例

以中国大陆居民赴“一带一路”沿线国家旅游安全感知事件为例，搜集2013—2018年我国大陆居民赴“一带一路”沿线国家旅游游记，从网络关系视角出发，分析并刻画其旅游安全感知事件的时空网络结构特征。研究发现：（1）中国公民赴“一带一路”沿线国家旅游安全感知事件分布存在集聚特征，在年尺度上表现出固化性；（2）从区域和国家层面分析得出旅游安全感知事件呈现出稳中渐变特征，如区域层面来说，西亚是旅游安全感知事件重灾区，而中亚是旅游安全感知事件的相对沉寂区；（3）各类旅游安全感知事件的空间分布同质性与异质性并存。

Spatio-temporal characteristics of Chinese outbound travel safety perception events from network relation perspective

It is necessary to analyze and reveal the temporal and spatial distribution characteristics of Chinese citizens' tourism safety perception events in these countries. The study collected the data of Chinese citizens' travel safety perception events in Ctrip,.Then, set up the tourist destination-tourist safety perception two-mode network. Using the SNA software, the safety space structure of tourism destinations and the measurement of centrality are analyzed. The findings are as follows :(1) The tourism safety perceived events present spatially clustering characteristics and solidification. Social environmental security perceived events account for a larger proportion than natural environmental events.(2) At the regional level, west Asia has always been the "gathering place" of tourism safety perception events, while southeast Asia has gradually become the gathering place of tourism safety perception events in recent years. At the national level, Pakistan and Russia have been the hot spots of tourism safety perception events.(3) Different tourism safety event types show some spatial heterogeneity.
