A Study of the Influence of Tourists’ Destination Image and Perceived Service Quality on Their Behavioral Intention

The purpose of this study is to understand the effect of tourists’ perception of destination image and service quality on their behavioral intention. A total of 1020 valid questionnaires were collected from tourists in Lukang Town, Taiwan, by means of convenient sampling. After descriptive statistics and PLS statistical analysis, the results show that: 1) Tourists’ image of Lukang town has a positive effect on their perceived service quality. In addition, it also has a positive effect on future travel behavior intention; 2) The service quality of tourists in Lukang has a positive effect on their future travel behavior intention. 3) This study also finds that service quality has a mediating effect on tourism behavior intention. Finally, based on the results of the study, suggestions for future research and tourism planning are put forward.


Introduction
In recent years, with the prosperity of tourism in Taiwan, people like to visit outdoor natural environments or villages and towns with well-preserved cultures on holidays [1]. Lukang Town, located in the central part of Taiwan, was once the economic transportation hub between the two sides of the Taiwan Strait during the Qing Dynasty. As a result, it has many unique historical, cultural, historic buildings, temples, food, and crafts. Lugang is rich in cultural history, ancient and magnificent historic buildings, delicious snacks with local characteristics, and folk festival activities with ancient flavor. Every holiday time, the streets and lanes are always full of people and traffic, which shows that Lugang has its unique image and attracts tourists [2]. According to Crompton's (1979) definition of image, image is the sum of people's beliefs, impressions, ideas, and feelings about certain objects, actions, and events [3]. Moreover, destination image has the function of communication, publicity, and marketing, which will help tourists to consider and decide the destination they want to choose [4]. Then, when tourists are attracted by the destination image and go to the tourism destination to engage in activities, what they are faced with is the local service quality. Previous studies on tourism have found that the image of tourists before visiting the destination is related to the service quality they feel on the spot. Moreover, the service quality will affect tourists' willingness to visit their destinations in the future, or their behavior intention [5]. Baker and Crompton (2000) considered that post tourism behavioral intention is an indicator of whether tourists return to their destination [6]. Therefore, according to the above background, the purpose of this study is as follows: 1) Analyze the effect of tourists' tourism image on tourism quality and behavior intention.
2) Analyze the effect of tourists' perception of the tourism quality of Lugang town on their behavior intention.

Literature Review and Research Hypothesis
In the field of tourism research, the concept of image is often used in the study of travel destination marketing and explains the choice of travel destination [4] [7], whether the generation of images will have a positive impact and substantial help on the tourism destination, and whether tourists will have a positive attraction to the tourism destination through the connection of images. Echtner and Ritchie (1993) proposed that the composition of tourism image can be divided into five aspects, including tourism attraction, tourism activities, tourism services, tourism visibility and tourism management [8]. Birgit (2001) divides tourism image into three dimensions, including natural landscape image, social culture image and local culture image [9]. For example, Binh (2020) studies that Vietnamese tourists always have a high and positive evaluation of Taiwan. Tourism destinations are mainly scenic areas in Taiwan, followed by Taiwan's customs and multi culture. Another factor that attracts Vietnamese tourists is the quality of service industry, people's friendliness and enthusiasm, and good social order. In the further empirical study, it is found that goal image has a positive impact on service quality [10]. In the study of Lin (2020), she found that tourists' image of the destination will affect their visiting behavior in the future, so she learned that the image of the destination has an effect on their behavior intention. Although destination image plays an important role in inspiring tourist behavior, the service quality that tourists feel when they travel to the destination is also very important [11]. Parasuraman, Zeithaml and Berry (1985) developed "service quality model", also known as "PZB model". The main concept is that consumers are the decision makers of service quality. If enterprises want to meet the needs of consumers, they must make up for the five gaps found in this model. The five gaps are: 1) the cognitive gap between customer expectations and managers; 2) The gap between managers and service specifications; 3) The gap between service quality specification and service communication process; 4) The gap between service delivery and external communication; 5) Customer expectation and service gap after experience. Although PZB model is widely used in consumer behavior research as the basis of service quality measurement, it has its limitations [12]. The empirical results of Fick and Ritchie (1991) show that SERVQUAL scale cannot effectively measure customers' emotional experience, because only considering the business model of service transaction, it ignores the relationship between social and psychological aspect [13]. For example, Mudner (2020) studies that Russian tourists attach a great importance to Taiwan's service quality. The highest value is tangible (tourist facilities, hotels, transportation, restaurants), reactive (tourism service staff's ability to meet tourists' needs), authentic (tourism service personnel can solve the problem of tourists' response), and the lowest value is reliability (personnel services of government tourism department and tourism industry) and empathy (Government Tourism Department and tourism industry personnel can care, care and take care of tourists) [14]. However, in the above research, there is no specific explanation for the specific impact on the destination tourism resources. For example, in Hong (2019) to study the behavior of Green Island tourists, it is found that the tourism resources of the tourist destination humanities and the quality of service will affect the willingness of the tour leaders to recommend the destination [15]. The behavior of tourists includes the choice of destination and visit, and is accompanied by the evaluation of tourism products and future behavior intention [16]. As behavioral intention is an important indicator to evaluate tourists' future revisit and recommend destinations to others, it is found that destination image and local service quality have an impact on tourists' behavioral intention [17] [18] [19]. Therefore, according to the above discussion and the purpose of this study, this study puts forward the following three hypotheses, and summarizes the relationship of the hypotheses as shown in Figure

Subject and Sampling
This study takes the tourists to Lukang town as the subjects. From June 1 to 9, 2018, a convenient sampling method was used to investigate the tourists in the parking lots of Wenwu temple and Mazu temple in Lukang town. Before conducting the questionnaire survey, tourists were asked about their wishes and to confirm that they were coming to Lukang for tourism, and then they were asked to fill in the questionnaire, according to their willingness. In this study, a total of 1200 questionnaires were given to tourists, 1058 questionnaires were returned, 38 invalid questionnaires were deducted, and 1020 valid questionnaires were returned, with the effective rate of 85%.

Questionnaire
This research tool is divided into five parts. The first part is "tourism destination vant study of tourism behavior intention [17]. The questions in the above three scales were answered on a 5-point Likert scale, and they were given 1 -5 scores respectively from "very disagree", "disagree", "common", "agree", "extraordinary consent".
The fourth part is personal data, including: gender, age, marital status, education level, occupation, income, residence and other seven items.

Data Analysis
The statistical analysis steps of this study are as follows : 1)

Destination Image Scale
The results from Table 1 show that the factor loading of each observation variable is more than 0.50, the CR and Cronbach's α are higher than 0.70, and the AVE of potential variables is higher than 0.50, which shows that the scale has good convergent validity.

Service Scale
The results from Table 2 show that the factor loading of each observation variable is more than 0.50, the CR and Cronbach's α are higher than 0.70, and the AVE of potential variables is higher than 0.50, which shows that the scale has good convergent validity.

Behavioral Intention Scale
The results from Table 3 show that the factor loading of each observation variable is more than 0.50, the CR and Cronbach's α are higher than 0.70, and the AVE of potential variable is higher than 0.50, which shows that the scale has good convergent validity.   3. I will be glad to advise the relevant competent authorities in case of any improvement in Lugang. 0.65 4. In Lukang, I will be happy to make suggestions to the relevant authorities. 0.74 5. As long as there are festival activities in Lukang, I will be happy to engage in tourism activities again. 0.77

Analysis of Discriminant Validity
The results in Table 4 show that the square root of AVE of all potential variables is between 0.74 and 0.79, and the AVE of each potential variable is greater than all the correlation coefficients in the same column and column, indicating that the measurement models of each scale have good discriminant validity.

Structural Model Analysis
The test of structural model is used in this study, and the results of structural equation model are shown in Figure 2. In the figure, the path coefficient is the standardized regression coefficient (β value). In terms of the relationship between the variables, the standardized coefficient among the variables shows that "destination image" has a positive effect on "service quality" (β = 0.47, P < 0.01).
In addition, destination image had a positive effect on behavioral intention (β = 0.32, P < 0.01). Then, "service quality" had a positive effect on "behavior intention" (β = 0.32, P < 0.01). From the above structural relationship, because destination image has a positive effect on service quality and behavior intention, we can find that service quality plays a partial intermediary role in the structural model. Furthermore, from the results of the relationship among the variables in Figure 2, we can find that the explanatory power of destination image on service quality is 22%, and that of service quality on behavior intention is 30%.

Discussion
The results show that tourists' image of Lukang has a positive impact on their current tour ism quality, so hypothesis 1 is supported. The results of the above analysis support the relevant tourism research [17] that tourists will compare their previous destination images after arriving at the local tourism. When the local service quality matches the previous image, they will feel better about the local service quality. For example, Chen (2019) studied the tourist image of Guanziling hot spring area in Tainan, and found that positive tourism image had a significant positive impact on service quality. The results of this study are similar [23]. Then this study finds that tourists' image of Lukang also has a positive impact on their behavioral intention, so hypothesis 2 is also supported. The re- cognition and emotion about the tourist destination, the easier it is to promote the tourists' intention to revisit and recommend. It is also similar to relevant research findings [24]. For example, Ho (2018) found that "destination image" has a significant effect on "behavioral intention", indicating that tourists have a correlation between "destination image" and "behavioral intention" of Danshui old street, and the tourists visit willingness have a correlation between destination image and behavioral intention [1]. Then, this study finds that tourists' perceived service quality has a positive impact on their behavioral intention during their stay in Lukang, so hypothesis 3 is also supported. This shows that in the process of traveling in Lukang, tourists will have an important impact on the quality of the preservation of historical relics, the service of scenic spots, the traffic conditions, the service of scenic spots, the catering service, the environmental cleaning, the traffic, the snacks and the public facilities. This will affect the willingness to come to Lukang town to engage in tourism activities in the future, as well as the willingness to recommend relatives and friends. Compared with the previous research [17] [18] [19] [20], the result is the same, that is, the service quality of the destination has an important effect on tourists' behavior intention. Finally, we find that service quality plays a mediating role between image and behavior intention. Although it is found that image has a direct impact on tourists' intention to revisit Lukang and recommend local places, it has a greater impact through the service quality of destination. On the whole, tourists' behavior intention of revisiting Lukang and recommending local places still plays a more important intermediary role in the service quality of local experience.

Conclusion
Based on the above discussion, this study has the following conclusions: 1) Tourists' im ages of Lukang town include diverse folk activities, well-known cultural relics, well-known snacks, well-known handicrafts and Mazu reputation. These images will have an impact on whether tourists feel the same service quality as the image when they visit Lukang. In addition, it also has a positive effect on future travel behavior intention; 2) The service quality experienced by tourists in Lugang, including catering service, environmental cleaning, scenic spot service, snacks and specialties, and residents' friendliness, has a positive effect on their future travel behavior intention; 3) This study also finds that tourists' image of Lukang town also has a mediating effect on tourism behavior intention from their feelings of service quality.

Suggestion
The results of this study show that tourists' perception of the diversified folk activities, well-known cultural relics, special snacks, well-known handicrafts and Mazu reputation of Lugang Town, and the service quality after traveling in Lu-gang town will affect tourists' intention to visit Lugang again in the future and recommend their relatives and friends to visit Lugang. So for the local government, the tourism promotion department, and the tourism industry. The first task is to maintain the protection of scenic spots and cultural ease, to maintain the environment clean and clear traffic parking and guidance. The abovementioned approach is also the focus of local tourism marketing so that tourists can have a good image of Lugang when receiving these messages. In addition, all kinds of goods and souvenirs sold, as well as the reasonable price of the restaurant, so that tourists can get a good reputation before visiting, and produce a good image. In the local tourism, the service quality is consistent with the previous image, so that tourists can travel again, and can recommend relatives and friends to visit Lugang. As the friendly attitude of local residents towards the visitors is also very important, Lukang town government and tourism promotion units have a close relationship. When promoting tourism in small towns, it is also necessary to publicize the importance of promoting tourism to residents and ask them to support the development of tourism.
