The tourism statistics in the real world would be benefit after the concept was clarified through introducing spatial scale perspective.

The positive Tourism Destination Identity is just like the spear and shield of destination, so it not only represents the competitiveness of the tourism brand but also acts as the firewall and brake of the crisis. However, in recent years, the network public opinion crises have occurred frequently in tourism destination, which had a bad impact on the destination image and brought great challenges to related government departments when guiding public opinions. If the crisis is not properly disposed, the image of destination will be damaged and the destination will lose the confidence and sense of honor of the tourism brand as well. Therefore, it is of great significance to study how to adopt appropriate and effective strategies to repair damaged image in the crisis of network public opinion for the healthy and sustainable development of tourism destinations. Given this reality, the author analyses the most influential tourism network public opinion crisis in 2017 - “Malicious beating and disfiguration event in Lijiang” based on the SCCT, focusing on digging, combing and analyzing the crisis situation, response strategies, media reports and public response by using case study method. Furthermore, in order to identify the core of public discussion and the object of responsibility attribution, this paper conducts an in-depth study of netizens’ comments by using word frequency analysis and co-existing analysis. It is found that the crisis situation was complex, including accidental and preventable cluster. However, Lijiang government mainly provided instructing information and deny strategy while responding, which had a great deviation from the response strategies advocated by SCCT, so that the effect of crisis management was not good. Finally, the author puts forward some suggestions on how to improve the image restoration of the tourist destination, then optimizes SCCT in the practice of travel destination crisis so that it can provide more guidance to the destination in the future.

With the maturity of Web2.0 technology and the rise of individual customers, online travel booking is increasingly favored by tourists. From the personal perspective of tourists, this study constructs a conceptual model to explore the formation mechanism of online booking behavior of tourists. The conceptual model proposed in this study mainly consists of variables such as attitude, subjective norms, perceived behavioral control, booking behavioral habits, risk perception, booking intention, and booking behavior. The study conducted a questionnaire survey on four destinations in Quanzhou, Xiamen and Shanghai, and obtained 382 questionnaires. Through the data analysis software such as AMOS and SPSS, the multi-level test of the direct, mediating and regulating effects of the model was carried out. The results show that: (1) Behavioral attitudes, subjective norms, and perceived behavioral control have a strong direct influence on the booking intention. Also, The booking intention is an important predictor of the booking behavior. The data results indicate that the planned behavior theory has a good explanation for the online booking behavior of tourists; (2) The tourist booking habits has a significant positive impact on the booking behavior, and can also influence the booking behavior through the intermediary effect of the booking intention; (3) Tourist risk perception has a significant negative adjustment effect on the two stages of booking behavior. And risk perception has a greater inhibitory effect on the conversion of booking intentions into real booking behavior. This study also proposes a tourism e-commerce platform marketing strategy system from the aspects of tourism product quality management, guidance of tourists' behavior habits, and reservation risk management. However, the occurrence of online booking behavior of tourists also has irrational behavior characteristics such as impulsive purchase and secular purchase. More theoretical discussions and empirical tests are needed in the future.

The theory of evolution influences nearly every aspect of humankind’s behavior research. Also, based on the theory of evolution, the evolutionary psychology appeared in 1990s is a new research area in modern western psychology. But by now, the two theories have no effect on the field of leisure study yet. From the perspective of evolutionism and evolutionary psychology, using historical and logical approach, the paper first sorts out how the gathering-hunting life style formed humankind’s body shape, structure, and function (including mind). Then, the paper points out that production and life styles in the traditional agricultural society, in comparison to the modern industrial society, better adapted to humankind’s nature that shaped in gathering-hunting society. The division of labor in modern industrial society (including industrialized modern agriculture) deprived quite a part of humankind’s usage of their structure and function, which led to the people’s discomfort. Therefore, the meaning of positive leisure is to make those part of deserted and unused body function be used creatively again, and make people’s mind feel happy and enjoyable. Based on this viewpoint, the paper puts forward four aspects of implications to the leisure study in the end: 1.Theoretically and logically, to unify and explain the current main theories about the leisure self-consistently; 2.The essence of leisure is to switch a person’s always engaged activities to other disparate things, namely, make his/her over-used body, function and mind rest and over-rested parts to be exercised; 3.Leisure activities should supply people some certain degree of effective physical and environmental stimulus, and simply to emphasize the comfort and convenience is not always right; 4.It is essential and urgent for researchers and policy-makers to consider how to afford people active leisure activities which are based on human being’s nature and to achieve human being’s full development and self-worth thereby.
