The Market Responses of Ice and Snow Destinations to Southerners’ Tourism Willingness: A Case Study from China

Round 1

Reviewer 1 Report

1.    I believe that the main goal of the study, the results of which the authors cite in the article was: to determine how to promote Olympic heritage sites - the 2022 Beijing Winter Olympics - especially tourism in national parks in Inner Mongolia. The article refers to such a type of tourism as ice–snow tourism. In the Russian periodization of tourism types, there is no such tweed (ice–snow tourism).  Closest in context, ski tourism. And describes various types of winter tourist activity.
2.    It should be noted that in Russian tourism practice there are no problems with the development of winter tourism or ski tourism. BUT, on the other hand, there is a problem of the effective use of Sochi Olympic facilities, so the results of this study are also important for the Russian tourism sector. Moreover, I believe that the second problem matters for any country where such major international events have been held. At the same time, the article examines China's experience in solving this problem, which may be of interest to other countries.
3.    I repeat, I believe that the value of the work is that the authors propose to increase the efficiency of using Olympic heritage sites
4.    With regard to the research methodology, I would advise you to use the publications of Russian researchers, since the problem of effective use of Olympic heritage sites also exists (For example, the works of Altukhov, Artemova and others)
5.    The authors managed to draw important conclusions based on the results of the study
6.    The links correspond to the text
7.    With regard to figures and tables: I would like to note Fig. 3 - the authors were able to demonstrate several important questions on the survey of respondents in one figure. In Fig. 4. - I believe that it would be possible not to include in the article, since due to congestion with numbers, the drawing is not perceived. I also note that Table 1 is overloaded with information, so it is difficult to understand.

Dear authors, your research is very interesting and important for the development of this type of tourism. I believe that the study should be published.

Dear expert:

Thank you very much for your comments and suggestions. Your comments are all valuable and very helpful for our revising and improving our paper, as well as the important guiding significance to our researchers. We have studied comments carefully and have made correction which we hope meet with approval. Revised portion are marked in purple color in the paper. The main corrections in the paper and the responses to your valuable comments are as follows.

 

 

Point 1: I believe that the main goal of the study, the results of which the authors cite in the article was: to determine how to promote Olympic heritage sites - the 2022 Beijing Winter Olympics - especially tourism in national parks in Inner Mongolia. The article refers to such a type of tourism as ice–snow tourism. In the Russian periodization of tourism types, there is no such tweed (ice–snow tourism).  Closest in context, ski tourism. And describes various types of winter tourist activity.

 

Response 1: Thank you for your approval. Aroused by you comments, we placed more emphasis on how to take the advantage of Winter Olympics to promote ice–snow tourism. Meanwhile, we also referred to more academic articles by reseachers from Russian, on which basis we further enrich and improve the content of our study. For example, further carrying out marketing promotion to fully capitalize on the legacy of Winter Olympics (Alexandrova et al, 2019). The corresponding correction is refected in the sections of introduction, literature review and discussion in the paper, and revised portion are marked in purple color.

 

Point 2: It should be noted that in Russian tourism practice there are no problems with the development of winter tourism or ski tourism. BUT, on the other hand, there is a problem of the effective use of Sochi Olympic facilities, so the results of this study are also important for the Russian tourism sector. Moreover, I believe that the second problem matters for any country where such major international events have been held. At the same time, the article examines China's experience in solving this problem, which may be of interest to other countries.

 

Response 2: Thank you for your comments, which induce our more attention on the impact of Winter Olympics. We referred to some worthy experiences of Russian after the 2014 Sochi Winter Olympics, for example, the Winter Olympics bring out the diversity of ice–snow tourism products (Alexan-drova et al, 2019); set the example for later environmentally friendly development of ice–snow destinations in the host country (Kuznetsova et al, 2014). These are reflected in the paper content, mainly in the section of introcuction. 

 

Point 3: I repeat, I believe that the value of the work is that the authors propose to increase the efficiency of using Olympic heritage sites.

 

Response 3: Thank you for your comment, which prompts us to further consider the importance of inducing the ice–snow sport participation willingness of Southerners who are the major tourist source in China. We also emphasized this in the paper. For example, the finding in this study that Southerners’ ice–snow sport paticipation willingness is still weak, helps to arouse the operators’ awareness to cultivate Southerners’ demands for ice–snow sports. This is beneficial for making full use of the ice–snow sport facilities. The corresponding contents are mainly in the section of discussion.

 

Point 4: With regard to the research methodology, I would advise you to use the publications of Russian researchers, since the problem of effective use of Olympic heritage sites also exists (For example, the works of Altukhov, Artemova and others).

 

Response 4: Thanks for your guidance. With the support of our existing conditions, we couldn’t find literature document by researcher Altukhov and Artemova. Given this, we searched other important publications of Russian researchers, mainly including researches of Volkov, Tishkov, Alexandrova, Kuznetsova, Vanova, Antipov, and Zheleznyak. And their researches have significant reference values for our study. For exapmle, Zheleznyak emphasized the significance of establishing the winter living culture relying on the environmental diversity (Zheleznyak, 2020). This contributs to address the homogeneity among ice–snow destinations. The corresponding contents are all reflected in the paper, mainly in the section of introduction, literature review and discussion.

 

Point 5: The authors managed to draw important conclusions based on the results of the study.

 

Response 5: Thanks for your approval. In this revision, we also consolidated the findings, implications and conclusions of our study.

 

Point 6: The links correspond to the text.

 

Response 6: Thank you for your approval. In this revision, we also consolidated our content.

 

Point 7: With regard to figures and tables: I would like to note Fig. 3 - the authors were able to demonstrate several important questions on the survey of respondents in one figure. In Fig. 4. - I believe that it would be possible not to include in the article, since due to congestion with numbers, the drawing is not perceived. I also note that Table 1 is overloaded with information, so it is difficult to understand.

 

Response 7: We are very grateful for you pointing out this for us. According to your comment, we remade Figure 4 (in the revised paper, it was changed into Figure 5 because a new figure was inserted). We find that the revised figure is more clear and readable. We also remade Table 1 according to your suggestion, and the revised table is more succinct and readable. The revised figure is in page 12 of the paper (Figure 5); and the revised table is in page 6 (Table 1).

Reviewer 2 Report

This paper is relevant and aligns with the aim and scope of the journal. However, it requires minor revisions to enhance its overall quality. My comments are as follows:

The abstract lacks a brief description of the methodology.

The introduction section is quite brief. It should be expanded to include past studies in this topic, clearly address the research gap, and provide a clear statement of the paper's structure.

The literature review is insufficient compared to previous studies. A clear definition of ice and snow tourism is missing. The authors could refer to reports from organizations such as UNWTO or WTTC for clarification.

There is a missing layout element on line 140.

The research method is duplicated under both heading 3 and heading 4. Please consolidate or clarify.

The results section is absent. The authors should modify heading 4 from 'Research Method' to 'Results.'

Please correct any typos present from line 313 to line 351.

The authors have not thoroughly discussed the obtained results, including necessary comparisons.

During writing the added contens, 17 more previous studies were cited (totally, 24 previous studies were cited in the introduction).

In the revised content, we clearly elaborated the study significance in addressing the research gaps, which exsit in the following aspects: aiding operators of ice–snow destinations to make more pertinent market response strategies; providing operators knowledge on potential tourists’ demand for various ice–snow tourism activities, on which basis proper market positioning can be formulated following consumers’ willingness; and detecting whether the available ice–snow tourism activities in north destinations correspond with major target customers’ willingness to engage in (if not, more effective market strategies should be adopted).

According to your comment, we added the satements of the paper's structure in fourth paragraph of the introduction part.

 

Point 3: The literature review is insufficient compared to previous studies. A clear definition of ice and snow tourism is missing. The authors could refer to reports from organizations such as UNWTO or WTTC for clarification.

 

Response 3: Thank you for your pointing out this for us. Accordingly, we expanded the literature review. Compared with former maniscript, 21 more literature documents were used in this revision. After the revision, we found that the literature review part was more fulfilling, and could provide more adequate support for this study.

We made definition of ice and snow tourism in the first paragraph in literature review part. Meanwhlie, thanks for you guiding us to access the information provided by UNWTO, we found the clear definition of tourism destination, and we cited the definition to our paper.

 

Point 4: There is a missing layout element on line 140.

Dear expert:

Thank you for giving us the opportunity to revise our manuscript, and we are very appriciated for your valuable comments. Your comments are all valuable and very helpful for our revising and improving our paper, as well as the important guiding significance to our researchers. We have studied your comments carefully and accordingly have made correction which we hope meet with approval. For your convenience in checking, the revised portion in the paper is marked in purple color. The main corrections in the paper and the responses to your valuable comments are as follows.

 

 

Point 1: The theoretical framework upon which this study is built requires further elaboration. Kindly provide a comprehensive explanation of the chosen theory, its relevance to the study, and its application.

 

Response 1: Thanks for your comments, which aroused our awareness that a theoretical framework is very important in the study. In this revision, we presented the theoretical framework of our studying, which was based on the theory of market positioning. The reason that we chose this theory as basis is as the follwing: we attempt to explore how to better respond to Southerners’ ice–snow tourism willingness for the north destination; during the ice–snow destination better respond the market willingness, it need to answer ”to whom, to what demand, and through which the responses should be”; these are closely related to the customer, demand and service positioning. In order to clearly elaborate our analysing framework, we also referred to 7 more relevant literature documents. We detailly presented the comprehensive explanation of the chosen theory, its relevance to the study, and its application in the first section of the research method part in our paper. We request your review.

 

Point 2: The gaps identified within this study need more thorough exploration. It is recommended to provide a detailed analysis of these gaps, covering both the background leading to the research and the current scenario. This should be effectively woven into the broader context through a comprehensive literature review.

 

Response 2: Thanks for your conductive suggestion. In order to further explain what gaps lead to the study, we rewrited and greatly expanded the introduction. 17 more previous studies (totally 24 previous studies) were cited for this. The gaps are mainly as follows. When the ice–snow tourism is rising after the Beijing 2022 Winter Olympics, given that Southerners are the major tourist source in China, more relevant studies are urgently required to provide operators knowledge on Southerners’ actual ice–snow tourism willingness to guide them to check whether their ice–snow tourism supplys correspond with major target customers’ willingness (if not, more effective market strategies should be adopted), to make more pertinent market positioning strategies, and to find ways to attract more Southerners to address the seasonal and sustainable prolems existing in north destination operations. We request your examination.

 

Point 3: The literature review is lacking some crucial references, particularly regarding the concept of "destination." Ensure that these key sources are adequately incorporated to provide a comprehensive review of the field.

 

Response 3: Thank you for pointing out this for us. Following your coments, we expanded the references. In whole paper, we added 35 references (5 previous references were deleted), and in literature review we added 21 more literature documents; meanwhile, we also quoted more contents from previously existing references. Based on relevant references, we elaborated the concept of “destination” and “ice–snow tourism”. We request your examination.

 

Point 4: To ensure the validity of the questionnaire, it is imperative to outline the specific data collection methods employed. Please include detailed information on how you arrived at a questionnaire with a total of 509.

 

Response 4: Thanks for your suggestion which makes us know the necessity of the description on data collection methods. We added the detailed description in this revision. The corresponding conten is in page 8, the second paragraph, and the added portion is marked in purple color. We request your checking.

 

Point 5: The "discussion" section should be closely intertwined with the data presented in Chapter 4. Strive for a more cohesive connection between Chapter 5 and the underlying data, promoting a more robust analysis.

 

Response 5: Thanks for your suggestion. According to your comments, we made the following revisions. (1) we rewrited the discussion part. In doing this we deleted some content that only had weak relevance with the data and analysis results in part 4. For example, the content “Ice–snow tourism in national parks also serves the public welfare. Operators should offer some public welfare services for winter tourism activities, …… ”was deleted. (2) During rewriting the content, we focused on what could be concluded from the invetigation and the analysis results. (3) When we drew a conclusion based on the data presented in part 4, we either noted based on which the conclusion was drawn, for example, we noted this was based on Table 1, Table 2, Figure 5, and others, or we stated according to what analysis result, we put forth the opinion, for example, the statement “enterprises need mainly focus their operation and marketing on the following tourism activities to expand the southern market: ……, (because) which have prominent driving effects on the ice–snow tourism willingness of those Southerners (this is the analysis result in part 4)”. We request your checking.

 

Point 6: Highlight the significance of this study. Explain its implications, potential applications, and how it contributes to the broader academic and practical realms.

 

Response 6: Thanks for your suggestion. In this revision, we made a great complement to the contents related with implications. In our former manuscript, we had a separate part for managerial implications (named conclusion and implications). Enlightened by your comments, in this revison, we mainly explained the implications of this study in the discussion section, because this would enable us fully discuss the academic and practical contribution of the implication. For example, an implication was that “potential tourists preferred projects needed less investment in fact”, and it contribution reflected as “being helpful for many small enterprises to positioning their development and operation”.

In addition, although some academic contributions were mentioned in the part of discussion, we still added a section of “theoretical contributions” to further expalin that the study contributed to formulating a sound market positioning mode of ice–snow tourism, and the possible theoretical reflections aroused by this study. We request your checking.

 

Point 7: Address the industrial relevance of this study. How does it offer contributions to the relevant industry? Articulate the ways in which the findings could be practically applied or shape future developments.

 

Response 7: Thanks for your suggestion, which required us to state the practical value of our study. Enlightened by your comments, we mainly elaborated the problems that this study would likely to address, thereby demonstrated the study contributions. For example, it was helpful to address the seasonal and sustainable problems existing in north destinations through guiding relevant enterprises to make sound market positioning to attract more Southerners. It was slso helpful for ski resort operators to diversify services to enhance their attractiveness, and this was likely to address homogeneous competition among ski resorts; and helpful to address the problem of mismatching between supply and demand to avoid the resource waste, among others.

 

Point 8: The quality of English writing requires further enhancement. Given the current state, the manuscript's English proficiency is inadequate for successful journal publication. Consider revisiting and refining the language to meet the journal's standards.

 

Response 8: Thank you for pointing out this for us. Although we asked editage (a company) to edit our English writing in our former manuscript, as you said, many problems still existed. After this revison, we invited one of our colleagues, who had ever been in England for 6 years and had published 5 papers in English, to check, revise and edit our writing. Meanwhlie, we planned to get an professional English revising and editing service from MDPI if the English writing needed further revision and editing.

Round 2

Reviewer 3 Report

 Thanks for the great revision. Also, I would like to draw your attention to some more details:

1. What methods can be used to avoid the fatigue of those who fill in the questions, or to improve their willingness and effectiveness in filling in the questions?

2. The significance of a literature review goes beyond discussing previous research; it involves extracting your own findings and conclusions from these reviews. This includes identifying the motivation for your research, addressing gaps in the existing literature, and highlighting aspects that differentiate your study from prior research. Therefore, I recommend that you consider revising and supplementing the content of your literature review.

3. In section 5.2 "Theoretical Contributions," please integrate your discussion with the previous literature.

 

There is an improvement compared to the previous version.

Author Response

Dear expert:

Thank you for your approval for our revision. We are very appreciated for your instructive comments and suggestions. We believed that your comments have played important function on our revising and improving the paper, as well as the important guiding significance to our researchers. We have carefully studied your comments, guided by which, we have made conscientious revision which we hope meet with approval. Revised portion are marked in purple color in the manuscript. The main corrections and the responses to your valuable comments are as follows.

 

Point 1: What methods can be used to avoid the fatigue of those who fill in the questions, or to improve their willingness and effectiveness in filling in the questions?

 Response 1: thanks for your pointing out this for us. You comments aroused our awareness for the necessity of clearly elaborating the investigation procedures in detail. Accordinglly, in the manuscript, we complemented the description on the method that was used to improve respondents’ willingness and effectiveness in filling in the questionnaire, as follows. (1) For on-site survey, we requested the investigator to conduct the questionnaire when tthey were in spare time. From past experience, we believed that when the respondents had free time and were relaxed, they would show more interest in the sruvey. (2) Some small gifts (for example, refrigerator magnets, mobile phone accessories, nail scissors, mini staplers, portable disinfectants, and others) were provided for respondent to choose one. We believed that this would show our sincerity and improve respondents’ attitude towards the survey. (3) Before the investigation, the investigator made a brief introduction about the 10 main categories of ice–snow tourism activities according to the prepared statements. We believed that this would enhance respondents’ awareness on our survey and improve their effectiveness in filling. (4) For the respondents (mainly being acquaintances of authors) who received and submitted the questionnaire online, we also sent the brief introduction mentioned above and an explanation on the survey’s importance for us to them. We believed that this would arouse their more attention on the survey.

For your convenience in checking, the modified contents are marked in purple color in the manuscript. We request for your checking.

 

Point 2: The significance of a literature review goes beyond discussing previous research; it involves extracting your own findings and conclusions from these reviews. This includes identifying the motivation for your research, addressing gaps in the existing literature, and highlighting aspects that differentiate your study from prior research. Therefore, I recommend that you consider revising and supplementing the content of your literature review.

Response 2: Thank you for pointing this out. Your comments are very valuable for us. Therefore, we made careful revision. First, we extrated some important fingdings from previous researches. Second, based on the findings, we identified some important issues that need to be further explored, which motivated us to do some related research. Third, referring to previous researches, we elaborated the possible contribution of our study to illustrate its difference from prior researches. For your convenience in checking, the modified contents are marked in purple color in the manuscript. The following is some examples.

• From relevant researches, we can find that a variety of attractive activities are key elements of ice–snow tourism. However, researches that systematically summarizing relevant activities in north destination of China are still insufficient. Therefore, we explores ice–snow tourism activities in the study areas, and then analyzes to which degree the activities can satisfy the potential consumers’ demand. This is helpful to make sound market positioning for the ice–snow destinations.
• Through literatures, we can infer that new growth points of ice–snow tourism lie in non-athletic activities, however, lots of operators don’t know what are the new growth points of ice–snow tourism in supplying. In order to cope with this problem, we need to find out the preferred activities by potential tourists and identify the new growth points, thereby to optimize the market positioning and promote ice–snow tourism growth. Nevertheless, research on optimizing market positioning targeting Southerners (the major tourists source in China) is still insufficient. Therefore, the study explores how to optimize market positioning based on Southerners’ willingness for different ice–snow tourism activities.
• Existing researches anlyzed the influencing factors on ice-snow tourism. However, we find that as the essential influencing factors, different ice–snow tourism activities’ influence effects have not been fully compared. Therefore, this study compares the inducing effects of different activities on Southerners’ ice–snow tourism willingness, particularly compares their inducing effects on the willingness of those who are more likely to travel for ice–snow tourism. From this perspective, the study consolidates the theory basis for the market positioning of ice–snow destinations.

For your convenience in checking, the modified contents are marked in purple color in the manuscript. We request for your checking.

 

Point 3: In section 5.2 "Theoretical Contributions," please integrate your discussion with the previous literature.

Response 3: Thanks for your comments, which makes us realize the necessity to improve the part of “theoretical contributions”. In this revision, we integrated 15 previous literatures into the discussion in this part. (1) With previous literatures, we can infer that exploring the proper market positioning mode for ice–snow tourism in China is very essential. And this study contributes to this. (2) Given that many researches emphasize that ice–snow tourism is threatened by climate change, which is likely to bring about some pessimism, this study helps to raise awareness that proper marketing positioning can still bring abundant development opportunities in the background of climate change, and this depending on making insight into diversified activities and potential tourists’ willingness for them. (3) Through analyzing existing literatures, the study find that the research focus is not in line with the major demand of potential tourists. This study result perhaps leads to the orientation change of some researches in the future, and that would be more beneficial for forming proper market positioning. (4) This study find that most tourists seek leisure living experience in ice–snow environment, and relevant leisure living elements always reflect as ice–snow culture. However, related researches show that local ice–snow culture has not been fully exploited in many destinations. Therefore, this study result perhaps can initiate more relevant discussion focusing on local ice–snow culture, which helps to differentiated the market positioning of ice–snow destinations.

For your convenience in checking, the modified contents are marked in purple color in the manuscript. We request for your checking.

 

 

Expert comments on the quality of English language: There is an improvement compared to the previous version.

Response: Thank you for your approval. In this revision, we also improved the English writing. If we still need to improve our English writing, we planned to get a professional English editing and revising service from MDPI according to the comments of the expert or editor.
