CHAPTER 1: OVERVIEW OF THE STUDY
1.1. Necessity of research
1.1.1. Theoretically
Increasing social income combined with the increase in world population has led to an increase in tourism demand. The question is why tourists choose one destination over another. Destination choice is an important research concept that has received the attention of many scholars in recent decades (Woodside and Lysonski, 1989; Um and Crompton, 1990; Ankomah et al., 1996; Sirakaya et al., 2001; Jang and Cai, 2002; Sirakaya and Woodside, 2005; Dolnicar and Huybers, 2007; Chen and Wu, 2009; Prayag, 2011; Mutinda and Mayaka, 2012; Yiamjanya and Wongleedee, 2014). “Tourism destination choice can be conceptualized as the choice of a destination by tourists from a set of alternatives” (Huybers, 2004, p. 1). Thus, tourism destination choice is a very important decision process not only for tourists but also for the destination. In order to remain competitive in the smokeless industry, tourism businesses need to understand the decision-making process and the destination choice decision of tourists is extremely important in developing strategic solutions to attract tourists (Costa and Ferrone, 1995).
Recognizing the role of tourism for development, in recent times, issues of tourism and tourist attraction have become the subject of research by many domestic and foreign scientists. In the world, studies have shown that there are many factors influencing the choice of destination (Guillet et al., 2011). According to Lang et al. (1997, p. 22), “in general, the basic factors in the models include the demographic components of tourists (age, income, life cycle, ...), psychological data (pursued benefits, preferences, attitudes, ...), marketing variables (product, price, advertising, ...), attributes related to the destination (attraction factors, situational variables, ...) and perception”. These influencing factors appear in studies individually or simultaneously.
Except for some studies that discuss the influence of destination choice on demographics, purpose and trip characteristics separately (Lang et al., 1997; Heung et al., 2001; Lim et al., 2008), most studies use push and pull theory to discuss the relationship between factors in the destination choice model. Kim et al. (2003) argued that the push and pull approach provides the best way to explain and predict individual travel decisions. Push and pull theory suggests that people travel because they are pushed by internal forces from themselves and pulled by external forces from destination attributes (Jang and Cai, 2002; Lam and Hsu, 2006; Mohammad et al., 2010). Specifically, Kim et al. (2003, p. 170) argue that “push factors are conceptualized as factors or needs that arise due to an imbalance or tension in the motivational system”, which drive or create a desire to travel. In contrast, the pull factors of a tourist destination refer to a combination of several multidimensional attributes of facilities and services that make the destination attractive to a particular individual in a choice situation (Hu and Ritchie, 1993).
According to Kotler (2001), customers are those who want to receive maximum value within their budget and knowledge. Faced with many choices for the variety of products and services, customers will choose the product that gives them the greatest satisfaction based on the set value expectations. Understanding what motivates people to travel is important in predicting the decisions of potential tourists and future travel patterns (Moore et al., 1995; Carr, 2002a, 2002b; Lam and Hsu, 2006; Chen and Tsai, 2007; Chen et al., 2011; Fratu, 2011; Kluin and Lehto, 2012).
Besides travel motivation, destination image is another research concept that helps explain destination choice. Baloglu and McCleary (1999a) demonstrated that destination image has an important influence on destination choice. Furthermore, Chi and Qu (2008), Jamaludin et al. (2012) found a relationship between destination image and future behavior specifically the impact of a destination image on tourists’ intention to revisit and recommend it to friends and relatives.
tourism. According to Prayag (2011), image is generally accepted as an important pull factor for the success and development of a tourist destination. Dominique and Lopes (2011) identify the main factors that characterize the image of a tourist destination, as well as their implications for tourism management. In short, destination image is one of the most important factors of a tourist destination and becomes a key factor for the success or failure of tourism management.
However, Oh et al. (1995), Srisutto (2010) suggested that the factors that may influence tourists’ destination choice are not simply push and pull factors but also include barriers. The findings provide evidence that tourists act on their consumption values, seek information from various sources, evaluate destination images and have some barriers in going to their chosen destination. Although barriers to travel have been noted in the tourism literature since the 1980s, only a few studies have applied the barrier concept in the tourism field (Nyaupane and Andereck, 2008; Hung and Petrick, 2010) and only Chen et al. (2013) examined the influence of travel barrier variables on destination image perception and destination choice in the case of young tourists to Brunei. In particular, the impact of barriers on motivation has only been proposed by Alexandris et al. (2011) in the field of recreation in general and studied in the case of recreational skiers, but has not been proposed by any research in the field of tourism. Therefore, measuring the relationship between travel motivation, destination image and destination choice under the influence of antecedent variables of travel barriers is still a big gap in research.
On the other hand, in previous studies, the most commonly used method to study destination choice is actually logistic regression with variants such as logit, multinomial logit, and probit (Morley, 1994; Jang and Cai, 2002; Seddighi and Theocharo, 2002; Hong et al., 2006; Lyons et al., 2009). Besides, some studies use discriminant analysis (Corey, 1996; Lang et al., 1997; Liu and Ko, 2011). In addition, some studies use ordinary linear regression using the least squares (OLS) method to analyze the regression.
