Introduction
With the profound adjustment of the global economy and the transformation of China's development stage,China is taking shape in a new development pattern with internal and external cycles as the mainstay and both internal and external cycles reinforcing each other [1].In China, which is rich in natural resources, outdoor sports, as an emerging sports activity, have a huge market potential, but they have not yet been fully integrated into the daily and sports fields.Under the background of globalization, the double cycle strategy provides a new idea and direction for China's industry [2].As an emerging industry,outdoor leisure sports industry plays an important role in promoting economic growth and improving people's quality of life [3].However, facing the complex and changeable market at home and abroad, how to improve the market adaptability of outdoor leisure sports industry has become an urgent problem to be solved.At present, the outdoor leisure sports industry is facing many practical problems.On the one hand, the domestic market demand is growing day by day, and consumers' requirements for the quality, diversification and individuation of outdoor leisure sports products are constantly improving [4]; On the other hand, the competition in the international market is fierce, and international brands occupy a dominant position with their advanced technology and mature market operation experience [5].In this context, China's outdoor leisure sports industry must strengthen its own construction, enhance market adaptability, in order to cope with the challenges of domestic and foreign markets.
Based on the above background and problems, this paper aims to deeply explore the key elements and theoretical logic of market adaptability of outdoor leisure sports industry under the background of double cycle through rooted theoretical analysis.As a qualitative research method, rooted theory emphasizes on extracting concepts and constructing theories from original materials, which is of great significance for indepth understanding of market adaptability of outdoor leisure sports industry.

Literature Review and Problem Raising
With the gradual establishment of the domestic and international dual-cycle development pattern, the outdoor leisure sports industry has ushered in unprecedented opportunities and challenges for development.In order to deeply analyze the key elements of the market adaptability of the industry, this paper will review the literature from the following aspects: First, the market status and development trend of the outdoor leisure sports industry are studied to understand the current market size, structure, competition pattern and future development trend, and provide the basis for the market adaptability analysis of the industry; The second is to analyze the outdoor leisure sports industry at home and abroad market demand changes related research, in order to master the changing trend and characteristics of market demand; The third is to explore the theory and practice of outdoor leisure sports industry market adaptability, in order to put forward effective market adaptation strategies and methods.

Related Research on Market Status and Development Trend of Outdoor Leisure Sports Industry
Through literature review and combing, it is found that the outdoor leisure sports market at home and abroad has been booming.At home,China's"double cycle" development strategy has not only brought profound changes in the market and policy environment for the outdoor leisure sports industry, but also stimulated the upgrading of consumer demand.In 1989, China's first civil outdoor society group was born.In 2008, the annual output value of the domestic outdoor sports industry exceeded 3 billion yuan, and it is expected to achieve nearly 20 times growth in the future, and is expected to reach 900 billion yuan in 2025 [6].This growth is mainly driven by multiple factors such as policy support, consumption upgrading and health awareness promotion.The China Outdoor Leisure Sports Industry Development Report (2022 edition) further confirms this trend and provides a detailed analysis of the key factors driving the industry's growth and potential growth opportunities in the market segment [7].This shows that China's outdoor leisure sports industry is ushering in a new stage of development driven by policy orientation, consumption upgrading and health concept transformation.In foreign countries, the Global Outdoor Recreation Market Report (2022) analyzes the development trend of the outdoor leisure sports market from a global perspective, including market size, growth rate, major players and future growth potential, providing a valuable reference for understanding the market dynamics at home and abroad.

Related Research on Changes in Domestic and Foreign Market Demand of Outdoor Recreation Sports Industry
The outdoor leisure sports industry can flexibly respond to changes in domestic and foreign market demand through continuous product innovation, precise market positioning and flexible marketing strategies [8].Domestically, China's sports industry includes four major categories of sports service industry, which are further subdivided into nine categories.In the distribution of output value in 2021, the subsectors of sports goods sales, sports marketing and facilities management, physical education and training, and outdoor leisure sports and fitness accounted for 16.5 percent, 7.9 percent, 7.4 percent and 5.8 percent, respectively.Among them, outdoor leisure sports such as hiking, camping and rock climbing are warmly welcomed by consumers.At the same time, the outdoor equipment market also showed a strong growth trend.The China Outdoor Sports Brand Development Report focuses on the market performance of domestic outdoor sports brands, exploring factors such as market share, brand building and marketing strategies [9].The Report on the Market Panorama Assessment and Development Strategy Planning of China's Camping Industry in 2022-2027 provides an in-depth analysis of the competitive landscape of the domestic outdoor leisure sports industry, involving multiple dimensions such as market share and competitive strategy.At the same time, the report "Competitive Landscape in the Global Outdoor Recreation Industry" from a global perspective gives an in-depth analysis of the competitive landscape of the global outdoor recreation industry, including major competitors, competitive strategies and market shares.Leading Companies in the Global Outdoor Recreation Industry introduces the leading companies in the global outdoor recreation industry, revealing information such as market position, competitive strategy and product innovation [10].Together, these reports show the vigorous development of the outdoor leisure sports industry.

The Theory and Practice of Market Adaptability of Outdoor Leisure Sports Industry
In the double cycle pattern, market adaptability is driven by policy, innovation, positioning and strategy.Yin Anna (2015) emphasized the core role of product innovation in enhancing industrial competitivenesst [11], while Dai Zhixin et al. (2023) pointed out that the policy environment promotes industrial transformation through financial suppor [12].Xue Wenzhong (2019) and Chai Wangjun (2022) both emphasize the importance of institutional guarantee and government regulation [13].In foreign countries, Molina Navarro and Rivera Mateos (2020) emphasize the need for governments to provide suitable natural environments and landscapes for leisure sports activities [14].Fancourt and Aughterson (2021) and Eigenschenk and Thomann (2019) both argue that it is essential to promote the health benefits of leisure activities [15] [16].Cho (2023) found through a questionnaire survey that consumers' choice of outdoor recreational sports products is affected by multiple factors such as personal interest, health status and economic ability [17].Kong, Dezhi., Sun and Jingzhu (2022) believe that the sports consumption pattern is changing from traditional physical consumption to participatory consumption, and propose the impact of the change of sports consumption pattern [18].The comparative study of global sports industry policies and the Study on Coordinated Development of Outdoor leisure sports industry Chain both provide valuable insights, emphasizing the importance of government support, natural integration and industrial chain optimization [19] [20].
The existing research on the outdoor leisure sports industry focuses on the macro perspective, the micro market demand and consumer behavior are insufficient, the theoretical system is not perfect, and the research methods are mainly qualitative, lack of quantitative and case studies, and international comparison is also scarce.The purpose of this paper is to systematically study the causal mechanism of market adaptability of outdoor leisure sports industry under the background of double cycle by using the grounded theory.Rooted theory emphasizes on extracting theory from actual data, which can deeply understand consumer behavior and market demand, and improve the theoretical system; At the same time, the theory can be combined with quantitative data verification to provide comprehensive and in-depth analysis; It also supports cross-cultural comparative research, revealing industrial differences and commonalities, and enhancing international vision.

Research Methods
Grounded theory, an important methodology of qualitative research, is known for its characteristic of constructing theories by induction in the natural environment.Based on this method, this paper deeply discusses the key elements and theoretical logic of market adaptability of outdoor leisure sports industry under the background of double cycle.Through the systematic analysis of multi-source text data such as policy documents, news reports and industry reports, the text analysis tool of Nvivo12 is used to efficiently identify high-frequency words and themes, and accurately capture core elements and features [21].This paper aims to build a comprehensive and in-depth theoretical framework to provide theoretical support and practical guidance for the healthy development of outdoor leisure sports industry.Through detailed coding analysis, we strive to reveal the key elements and logic in the development of the industry, and provide a strong basis for its adaptation to the double cycle background.

Data Collection
Based on multi-channel data, this paper deeply discusses the market adaptability of outdoor leisure sports industry under the dual-cycle background.By collecting official policies, news and reports from the General Administration of Sport of China, local government culture and sports bureaus, industry associations, and relevant literature in academic databases, as well as information from the Department of Education and Sports Bureau, a total of 330 relevant text materials (policy text 48, news text 36, report text 78, interview 28, other such as editorials and literature 140) were screened and sorted out.Which provides strong data support for the research of this paper.In data screening and sorting, scientific methods are strictly followed to ensure data representativeness and research depth.Multiple rounds of extraction and coding were carried out for 380 text materials from 2014 to 2023.In the first round, 20 samples were extracted and coded every year to grasp the core content.In the second round, another 10 samples are selected each year for in-depth coding, verification and rich analysis.When the new samples no longer provide new information, it is considered that the theory has become saturated, which lays a solid foundation for the research of this paper.In terms of sampling strategy, flexible adjustment is made for the difference in the number of text data: in 2019-2021, there is less data, using two-round extraction coding; While in 2021 and 2023, with abundant data, three rounds were conducted to ensure a wide range of samples and in-depth research.The selection of 2014-2023 as the research period is based on the full implementation of the double-cycle policy, significant policy effects and market changes, abundant data availability, and the rapid development of the outdoor leisure sports industry market.This strategy ensures that while guaranteeing the representativeness of the sample, the feasibility and efficiency of the study are also fully considered.This study focuses on the market adaptability of outdoor leisure sports industry under the background of double cycle, and uses Nvivo12 software to conduct in-depth analysis of 330 text materials such as policies, news, interviews and reports.First of all, the text data were sorted by year to ensure the timing; Then, the text is imported through Nvivo 12 software for open coding, that is, sentence by sentence analysis to form the initial concepts, such as "outdoor leisure sports industry" and "market positioning and segmentation".Further, these initial concepts are summarized and refined into higher-level categories, such as "market strategy and innovation" and "internationalization and localization", which together form the core analytical framework of this study.This process not only deepened the understanding of the text content, but also provided a solid foundation for the subsequent theoretical discussion and empirical research, and finally extracted 15 initial categories closely related to the market adaptability of the outdoor leisure sports industry under the background of double cycle.Table 1).

Spindle Coding to Establish the Main Category
