Research on the Behavior of College Students’ Online Tourism Booking Based on TAM

With the rapid progress of social economy, online tourism booking has newly become a highlight for China’s tourism trade and its development. College students, who have abundant disposable time, gradually build up as great tourist forces adept at using network resources. By both literature research and empirical research, this paper explores the factors affecting college students’ online tourism decision-making. By establishing college students’ online tourism booking behavior model based on TAM, and empirically ana-lyzing 161 pieces of data based on SPSS22.0 and PROCESS macro plug-in, the hypotheses and modified model are verified. According to the results, perceived usefulness is still the most important factor in the college students’ online tourism booking behavior model, while perceived ease of use is another essential one. Usage attitude and usage intention are combined into a common factor—“usage attitude and intention” affecting the model; Negative Internet word-of-mouth plays a moderating role in the relationship between perceived usefulness and usage attitude and intention, and perceived usefulness and perceived ease of use together act as an intermediary in the model.


Introduction
As the era witnesses rapid development of tourism and Internet information technology, the Internet has imperceptibly changed the modern lifestyle and state. According to the 44th Statistical Report on the Development of Internet in China, published by China Internet Network Information Center (CNNIC), consumption and overseas tourism consumption all ranked the top in the world in 2018 and has been in constant grow, indicating the increasing tourism demand of Chinese residents [2]. Driven by the rapid growth of tourism consumption, online tourism booking has developed rapidly. Among the Internet applications in business transactions, online tourism booking has ranked the third on usage rate, just behind online shopping and take-out, with 418 million Internet users, accounting for 48.9% of the total. In that case, more and more enterprises and users have accepted online tourism booking. Among the netizens, students account for the highest proportion, up to 26% [1].
At present, the competition among the online tourism booking platforms is becoming increasingly fierce, making how to attract potential consumers to book and consume an important topic for the tourism E-commerce platforms.
Online booking is also the extension and embodiment of information technology in tourists' consumption behavior [3]. Meanwhile, with the rapid development of social economy and the improvement of people's living standards, college students, as a group with more disposal free time, have taken tourism as an important way of leisure and entertainment, while as powerful targeted users who are good at using network resources, their laws and directions when using online tourism booking are worthy of further exploration.
As such, the purpose of the current work has two aspects. Based on the Technology Acceptance Model, according to the current situation of college students in Internet use and related features of tourism products, a college students' online tourism booking behavior model is constructed to explore the influence of perceived usefulness and perceived ease of use on online travel booking behavior. Discusses the power of negative Internet word-of-mouth to introduce the public word of mouth of trustworthy objects, namely, the Internet word-of-mouth model, into the online travel booking behavior model of college students, discusses the moderating effect of Internet word-of-mouth on the online travel booking behavior model of college students, and enhances the explanatory power of the model. In general, the main focus of this paper is to study the key factors and influencing mechanisms that influence the booking behavior of college students.

Online Tourism Booking Behavior
Online tourism booking refers to that tourists, through Internet or telephone, book tourism products or services like flight tickets, hotels, holiday products, etc. from tourism service providers and pay online or offline. According to the With the increasing scale of Internet users and the diversification of online tourism service business mode, the researches on online tourism booking behavior at home and abroad are also gradually emerging. Foreign scholars have a relatively early understanding of it, realizing the change of tourists' consumption behavior in the Internet age. Buhalis and Licata (2002) showed in their study on Taiwan that the online tourism transaction volume dominates the B2C tourism e-commerce, making customers be accustomed to conducting independent tourism information search and self-booking of tourism products through the network [4]. Matzler et al. (2006) took online train tickets booking as an example, believing that website availability had a great impact on the booking motivation and satisfaction [5].
Among the research on online tourism booking behavior in China, Chen Haipeng et al. (2007) discussed the main reasons why consumers choose online tourism booking: time saving, comprehensive information and low price [6]. Based on consumers' features, Bao Fuyuan (2010) conducted in-depth study on the reasons and related factors contributing to the online booking, among which time saving, available information comparison and cheap price, etc. Product information, timely and effective communication with customers, and transparent tourism product cost performance are the primary factors [7]. Li et al. (2005) identified and measured the determinants of Chinese e-commerce consumers' online purchase of tourism products from seven independent sets of variables affecting Internet consumer behavior, and explored the process of online tourism consumers' transformation, from a "watcher" to a "consumer" [8]. Zhu Jingyan (2014) showed in her research on the online booking behavior of tourism website users that the implementation of the booking behavior signaling the tourism website users' transformation process from browsing to purchasing. According to the differences in online booking behavior, users are divided into four categories, and the online booking behavior characteristics of different types of tourism website users are described respectively [9].

Technology Acceptance Model
Technology Acceptance Model (TAM) was proposed by Davis (1989) when he used the theory of rational behavior to study users' acceptance of information system, aiming to explain and predict users' status of information system acceptance after interaction with the system over a period of time [10]. The model presents two main determinants: perceived usefulness, as "the degree to which a person believes that using a particular system would enhance his or her job performance". In contrast, perceived ease of use refers to "the degree to which a person believes that using a particular system would be free of effort" [10]. The X. R. Chen, Z. Li Journal of Service Science and Management framework of this model is shown in Figure 1.  [16], and the significant positive impact of perceived ease of use on attitudes [17]. It is worth noting that in the study on the usage intention of smart tourism system in scenic spots by Xu Feifei et al., perceived ease of use significantly affected the usage intention positively [18]. Also, some scholars' research results show that the significance of some routes has not been effectively supported [15]. Therefore, the relationship between variables in the technology acceptance model may be adjusted according to different research objects and research contents. Hence, the following eight hypotheses are proposed: H3. Perceived ease of use has a significant positive effect on perceived usefulness.
H4. Perceived ease of use has a significant positive effect on attitude.
H5. Perceived ease of use has a significant positive effect on usage intention.
H6. Perceived usefulness has a significant positive effect on attitude.
H7. Perceived usefulness has a significant positive effect on usage intention.
H8. Attitude has a significant positive effect on usage intention.
H9. Perceived ease of use and perceived usefulness mediates the overall model.

Internet Word-of-Mouth
Internet word-of-mouth refers to the behavior of consumers, through the Internet, passing on positive and negative opinions about products and services to other consumers [19]. In nearly a decade, academia and the business field have focused on and explored tourism Internet word-of-mouth. The survey conducted by Jin Zexin (2017) shows that 100% of online users tend to share through online interaction after tourism [20], and the word-of-mouth from these online reviews, serves as an important information source for consumers, as well one of the important factors influencing the consumer decision-making [21], besides, it is an important factor for booking service products and decision making [22]. Qin Qiongyu (2012) found that the perceived usefulness and ease of use from Internet word-of-mouth directly affected the development of tourism routes or the selection of tourism products, while the strength of the relationship between tourists themselves and Internet word-of-mouth disseminators directly determined further online communication [23].
As for categories of Internet word-of-mouth, positive and negative, each respectively has different effects on consumption decisions. On the one hand, consumers are more willing to share and spread negative information instead of satisfying consumption experience. On the other hand, compared with positive word-of-mouth, consumers pay more attention to negative ones, which affect their cognition, attitude and purchase intention [24]. Due to the universality and anonymity of the Internet, the influence of negative word-of-mouth is further amplified [25]. Shen Han found that the publicity effect of negative Internet word-of-mouth is significantly greater than that of positive one [22]. It can be seen that negative Internet word-of-mouth has more influence and destructive power on tourists' decision-making. Based on it, the following hypotheses are proposed: H10. Negative Internet word-of-mouth moderates attitude and usage intention. tal. Likert's scale of 5 grades is used in questionnaire in which respondents are asked to rate their opinions and attitudes towards online tourism booking according to the grades of "5" means "strongly agree"; "4" for "relatively agreement"; "3" for "uncertain"; "2" for "disagree"; "1" for "strongly disagree".
The first part is the pre-questions, which focuses on the education background and stages of the respondents, including two questions with each giving the options. The questionnaire would be stopped if the respondents are not college students.
The second part is the measurement on the Internet access and the basic information of online tourism booking (air tickets, hotels and tickets), which is mainly used to measure their experience in network use by asking 7 questions.
The third part is about the acceptance survey on the online tourism booking, a total of 20 questions.
The fourth part is about the impact of negative Internet word-of-mouth on online booking behavior, including three questions.
The fifth part is a survey on basic personal information of respondents, including gender, average monthly living expenses and the number of trips in the recent year and the city where the university is located.

Questionnaire Structure
These questionnaires have been conducted distributed and collected on an online survey platform for two weeks. A total of 163 questionnaires were distributed and all were collected, with a collection rate of 100%. Among them, there are 2 invalid questionnaires and 161 valid ones, with an effective rate of 98.8%.
The following criteria are adopted for the judgment of invalid questionnaires: 2) The answers are same and the duration is not long enough.
According to the data collected from questionnaires, the distribution of sam-

Data Analysis
Data support for the conclusion of this paper is provided by questionnaires which are used to collect the data of college students all over the country. The

Exploratory Factor Analyses (EFA)
As can be seen from Table 2, the KMO statistic value of the data is 0.922, greater than 0.90 with the significance level is 0.000, indicating that the questionnaires have a good structural validity and are very suitable for factor analysis. By using SPSS22.0, the characteristic values of 5 factors are found to be greater than 1 through factor analysis, deviating from the original assumption.
As can be seen from Table 3   The characteristic value of the fifth common factor is 1.027, and the overall variance contribution rate is 8.000%, which is named as "relevant experience (RE)" with CR value of 0.720.
The cumulative variance contribution rate of these four factors is 69.959%, indicating that the factor analysis can largely reflect the overall information, and the structural validity of this scale is acceptable. And through the factor analysis, attitude and intention are merged into a dimension, together with "perceived usefulness", "perceived ease of use", "negative Internet word-of-mouth", "relevant experience", corresponds to theoretic model mentioned above. To some extent, they verify the content validity of the scale.

Regression Model
To verify the effectiveness of the research model in this paper, a regression analysis is conducted on four factors: perceived usefulness, perceived ease of use, attitude and intention, relevant experience. The default data in this study is normally distributed, so model 6 of the PROCESS program is used to verify the regression path coefficient of the model composed of the above four factors, and the significance level test is also conducted to verify the validity of the hypotheses proposed above, and further modify the research model. If the path coefficient between two variables passes the significance test, it means that the path coefficient is not statistically significant to zero and the two variables are correlated, otherwise they are not significantly correlated (Table 4).
Through regression model results of Table 5 and Table 6 and 5000 times of the bootstrap analysis, in the original hypotheses, all pass significance test expect the impact of relevant experience on the perceived usefulness, namely the H2 fails to pass with H1 and H3 pass, H4 and H5, H6 and H7 pass with being merged into a general hypothesis. The higher the relevant experience value, the stronger the perceived ease of use, but it does not directly affect the perceived usefulness. Is it possible to mediate the perceived usefulness through perceived ease of use? It will be analyzed in detail by the mediating effect. The perceived ease of use will strongly affect perceived usefulness, and the improvement of both will produce an upward attitude and intention by causing influence of medium intensity, prompting respondents to generate intention, and more willing to buy related tourism products and services online.

Moderation and Mediation Analysis
In the PROCESS program, model 6 and model 4 are selected to verify the mediating effect of perceived ease of use and perceived usefulness. In the mediation X. R. Chen, Z. Li Note. ***p < 0.001; SC = standardized coefficients; LLIC = lower limit confidence interval; ULCI = upper limit confidence interval.  Note. *p < 0.05 **p < 0.01 ***p < 0.001; LLIC = lower limit confidence interval; ULCI = upper limit confidence interval. It can be seen from Table 7

Conclusions
This study attempts to explore the key influencing factors and links of college Compared with previous research results, it is found that perceived usefulness is still the key factor influencing consumers' online tourism booking behavior, while perceived ease of use is another important factor. However, for college students, attitude and intention are combined into a common factor, which together have an impact on the college students' online tourism booking behavior.
Theoretically, the study on the influencing factors is conducive to further exploring college students' online tourism booking behavior. By studying the college students' online tourism booking behavior model based on TAM, it is found that 67.867% of this model is explained by perceived usefulness, perceived ease of use, attitude and intention toward using, relevant experience Internet word-of-mouth. Consistent with previous studies, perceived usefulness is still the most important intermediary factor, which is significantly related to the attitude and intention, which perceived ease of use is another important factor affecting attitude and intention.
There is a significant positive impact between relevant experience and perceived ease of use. That is, the more relevant experience college students have, the easier for them to identify the authenticity and effectiveness of information, so as to understand its practicality and operation, the more they perceive the ease of online tourism booking. And the intermediary effect of perceived usefulness and perceived ease of use perception impact the attitude and intention of online booking. Negative Internet word-of-mouth has a negative moderating effect on the relationship between perceived usefulness and attitude and intention. This is because of the rapid development of network information, the credibility of network information is becoming lower and lower, and the authenticity of many positive word-of-mouth needs to be studied, while that of negative one is relatively large. Therefore, college students pay more attention to negative one and whether they will buy online products or services is affected by it.

Implications
This study provides favorable theoretical support for the tourism e-commerce platform that offers customized tourism products for college students. Because of the perceived usefulness is still a key factor affecting college students' online tourism booking behavior, so tourism enterprises should take the demands of college students as the center, from the perspective of their perceived usefulness design reasonable online booking products and services so as to improve repeated purchase rate, develop more potential users and promote the stable and healthy development of online tourism. Furthermore, college students are active and willing to share their own feelings online. Compared with the positive Internet word-of-mouth, the negative one plays a significant negative regulatory role to the attitude and intention, so online tourism booking platform needs to pay more attention to the public opinion monitoring. More importantly, it needs to solve the problem at its source by providing real, cost-effective products and services, and fluent booking process, effective and timely feedback and after-sale mechanism, meanwhile, control technology and service level at each key node of online booking, making respondents enjoy the thoughtful service, and buy the products they prefer, as well completing high-quality online booking and offline experience and reducing the negative online word-of-mouth at the source to improve its online booking intention.

Limitations and Future Research
This study is not free of limitations. Firstly, the sampling size in this study is insufficient due to comprehensive reasons. 60% of the 161 questionnaires are collected from Southern China, mainly scattering in Guangzhou and Shenzhen, so the data analysis and empirical research conclusions are not representative enough. Moreover, research objects can be further subdivided to carry out empirical research on college students in first, second and third-tier cities, so as to provide more targeted research results and data support for tourism enterprises and online tourism booking platforms.
Secondly, the influencing factors account for the model need to be further explored from other perspectives for they are diversified. This paper only introduces the negative Internet word-of-mouth as a moderating variable and relevant experience as an external variable to conduct relevant research and make new findings. From the perceived risk or other angles, the influence of perceived risk or other factors on the online tourism booking behavior could be further studied, and research model of college students' online booking behavior could be further explored too, with the purpose of conducting a more comprehensive analysis on the impact mechanism, embracing better understandings to the motivation of college students choosing online booking.
