With the advent of the Internet era,the Internet is not only a channel for people to obtain information,but also a platform for creating and sharing information.The big data formed by these network behaviors contains people’s needs and preferences,and has been continuously applied to related research in recent years.The development of red tourism can not only promote the development of old revolutionary areas and bring economic benefits,but also play the function of patriotic education and enhance national identity.With the strong support of national policies,China’s red tourism has a strong momentum of development.However,there are still problems such as uneven regional development,weak experiential and insufficient supporting factors,so the characteristics of tourism demand are analyzed with the help of network big data in order to promote the high-quality development of red tourism.Taking the attention of red tourism network as the research object,Baidu search index,online travel text and statistical data as data,and using mathematical statistical analysis,text analysis method and gray correlation analysis to explore the temporal characteristics,spatial characteristics,content characteristics and influencing factors of red tourism network attention,the main conclusions are as follows:(1)The inter-annual change of red tourism network attention shows a relatively stable growth trend,the overall index shows "two valleys and one peak",the PC side has a downward trend year by year,while the mobile end is increasing year by year.There are obvious seasonal changes in the attention of the red tourism network,the off-peak season is obvious,and the peak season is long,the off-season is short,and the peak season is mainly concentrated in spring and summer.The intra-week distribution is mainly concentrated in the first half of the week,reflecting the precursor effect of online attention on travel.(2)The spatial distribution of attention of red tourism network is uneven,and it decreases ladder-like from east to west.From 2011 to 2021,the discreteness of red tourism network attention increased first and then decreased,indicating that the attention of red tourism network changed from concentrated to uniform in spatial distribution.However,the concentrated distribution characteristics within each region are more obvious than those in the whole country,and the four regions of Northwest,North China,South China and Southwest China have large differences within them.(3)In terms of content characteristics,the hot spots of red tourism network are,in descending order: tourism resources,historical figures and historical events,emotional experience,tourism location,tourism transportation,tourism time,tourism accommodation,tourism food and tourism consumption.Tourists’ satisfaction with the red tourism experience was high,and the emotional tendency of positive emotions was as high as94.18%,and the content types of positive and negative expressions in various emotional tendencies were basically the same.(4)The strength and weakness of the factors affecting the attention of red tourism network were as residents’ living standards,tourism development levels,economic development levels,population size,network development levels,supporting facilities levels,transportation development levels and education development levels.For different regions,the influence of education development level and transportation development level on the attention of red tourism network is relatively weak,and the influence of other factors on the attention of red tourism network in different regions is quite different,and the size and ranking order of indicators under each influencing factor are also different. |
