The National Games are an important part of my country's national system of competitive sports and are the highest-standard and largest comprehensive sports event in China. At present, the National Games are in a state of outstanding competitive sports and lagging economic functions. The reason is that the National Games market development is regarded as a short-term and independent project, resulting in temporary organizational structure, broken operation cycles, blurred rights and responsibilities mechanisms, and short-term development goals. Based on the perspective of "National Games economy", this article proposes that the market development of the National Games should carry multiple missions of sports industry upgrading, building a sports power and regional coordinated development. It is urgent to establish a cross-cycle national Games brand asset management as the core equity development paradigm. Based on the experience of Olympic marketing, we will build an equity-based market development system with resource grading, subject division of labor and profit distribution as the pillars, and propose a promotion path of brand shaping, legal system improvement, organizational permanent establishment and inter-government coordination, in order to provide theoretical reference and practical guidance for the market development and reform of the National Games.

The 15^th National Games of the People's Republic of China (hereinafter referred to as the "15^th National Games") is not only an in-depth test of the coordinated development capability of the Guangdong-Hong Kong-Macao Greater Bay Area, but also poses a challenge to the traditional legal practice model based on a single jurisdiction.The practice risks of lawyers in cross-border sports events stem from the professionalism of sports legal services, the diversity of the legal relationships involved, and the particularity of cross-jurisdictional operations. In the fields of event commercial development, protection of the rights and interests of athletes and relevant personnel, cross-border data flow and personal information protection, employment relations arising from cross-border personnel movement, and event dispute resolution mechanisms, high requirements are placed on lawyers' professional capabilities, and considerable practice risks are also inherent.Lawyers shall bear liability for compensation if they cause losses to clients due to their faults. When engaging in the drive to build a leading sports nation and a rule-of-law bay area, lawyers must remain highly vigilant about the inherent risks of cross-border practice and proactively enhance their risk prevention awareness.

As a key practice in regional sports integration and development, the joint hosting of sports events in Guangdong, Hong Kong, and Macao plays a pivotal role in reconciling differences in legal systems and resolving cross-domain conflicts in sports event market development. This research provides a vivid practical example and innovative testing ground for promoting regional sports governance collaboration. Using literature review, rule analysis, case analysis, and comparative research, this study identifies the legal difficulties currently facing the market development of sports events in the three regions: difficulties in cross-jurisdictional protection of event logos, obstacles to cross-jurisdictional transfer of event intangible assets, and the dilemma of efficiently resolving cross-jurisdictional disputes. By systematically examining the practical explorations of the 15^th National Games in terms of organizational coordination mechanism innovation, cross-jurisdictional coordination and differentiated adaptation of rules, and cross-jurisdictional dispute resolution, and drawing on the core principles of regional rule of law development theory, this study proposes a breakthrough path for legal collaboration in the development of the joint hosting of sports events in the post-National Games era. This research requires a systematic solution based on four dimensions: tool empowerment, rule coordination, mechanism connectivity, and subject interaction.

In the new journey towards the Chinese path to modernization, incorporating mass sports into the National Games is not only an inevitable requirement for deepening the national strategy of fitness-for-all and promoting the high-quality development of mass sports, but also an important opportunity to promote the comprehensive and coordinated development of the sports industry. By employing research methods such as literature review and logical analysis, this study analyzes the value implications, practical considerations, and future directions of mass sports events in the National Games during the process of the Chinese path to modernization. The research suggests that the National Games mass sports events are an important means to implement the national strategy of "fitness-for-all", a crucial link in building a higher-level public service system for fitness-for-all, a unique platform for promoting the Chinese sports spirit and healthy lifestyle, and an effective carrier for promoting individual comprehensive development and social harmony. However, there are challenges such as imbalanced allocation and inefficient utilization, weakened sense of experience and achievement, insufficient spiritual guidance and brand building, and obstacles to inclusivity and participation. Looking ahead, we must adhere to strategic guidance and integrate into the overall national situation; persist in optimizing efficiency and activating resource allocation; uphold the people-first principle and strengthen participation incentives; persist in cultural soul-building and telling the stories of the masses well; and adhere to prioritizing inclusivity and expanding coverage depth.

The significant institutional shift in the governance of sports systems from a “competitive sports - centric” model to the “Qunjing Synergy” paradigm (the coordinated development of mass sports and competitive sports) is marked by the inclusion of mass sports events into the official competition framework of the 13^th National Games of the People's Republic of China. this transformation not only reflects the deepening of the national fitness strategy under the context of a sports powerhouse but also underscores the institutional innovation demands for reconstructing sports publicness. Grounded in the theoretical framework of Qunjing Synergy, this study employs institutional analysis and policy document review methodologies, combining critical policy nodes and practical cases to elucidate the synergistic driving mechanisms of four institutional logics: political integration, cultural identity, resource coordination, and social participation. It further examines structural tensions in practice domains, including conflicts in value objectives, misaligned governance structures, exclusionary rule systems, and deficits in participation motivation. Findings reveal that current mass sports events face formalistic institutional embedding dilemmas, with collaborative advancement mechanisms hindered by policy implementation disengagement, rule system misalignment, and weakened stakeholder coordination. Based on these insights, the study proposes an adaptive governance framework of “institutional integration - governance innovation-resource feedback-culture fusion” to provide theoretical support for optimizing the sports governance system in the new era.

To promote the integration of Hong Kong and Macao into the national development framework and to build a world-class bay area, this study explores the holistic governance of the 2025 National Games in the Guangdong-Hong Kong-Macao Greater Bay Area. Using literature review and logical analysis methods, it examines the current situation and value orientation of holistic governance in the Games and proposes practical governance pathways. The study identifies four major value orientations: transforming economic vitality into economic growth, advancing coordinated development and urban agglomeration, enhancing cultural exchange and cultural industry development, and empowering regional innovation through technology. Accordingly, it suggests governance pathways that leverage sports to stimulate economic vitality, promote synergy to build a world-class city cluster, empower culture to co-create the “Humanistic Bay Area” event brand, and integrate technology to foster innovation and construct a Smart Sports Bay Area.

Hosting major sporting events has become a significant force in driving regional economic and social development as well as cultural exchange. The Guangdong-Hong Kong-Macao Greater Bay Area's hosting of the 15^th National Games will facilitate the coordinated development of regional sports initiatives and accelerate the construction of the Sports Bay Area. This study employs literature review and field research to explore the intrinsic value and obstacles of the 15^th National Games in empowering the development of the Guangdong-Hong Kong-Macao Sports Bay Area, while identifying optimization pathways. The study concludes that the 15^th National Games demonstrates unique value in: - Promoting the renovation of sports venues to empower the development of a smart sports bay area; - Catalyzing urban development planning to empower the development of a modern sports bay area; - Boosting industrial synergy to empower the development of an industrial sports bay area; - Deepening regional cooperation and exchanges to empower the development of a cultural sports bay area. However, obstacles persist in this empowerment process, including: insufficient influence of major sporting events and underdeveloped sports markets; significant institutional differences between Hong Kong/Macao and the mainland, leading to regional development imbalances; inadequate sports-related laws and regulations creating barriers to event participation; and insufficient coordination in sports cultural exchanges, requiring further advancement of deep integration. Looking ahead, the Greater Bay Area must draw on the experiences of the world's three major bay areas to fully develop the “Three Regions, Three Centers” framework. It should leverage regional connectivity advantages to advance “hard connectivity” in sports infrastructure; break down barriers and unify standards to implement “soft integration” of sports regulations; and deepen exchanges aligned with contemporary trends to foster “heartfelt integration” of sports culture.

The National Games in 2025 being jointly hosted by Guangdong, Hong Kong and Macao for the first time is a big step in the coordinated development of the Guangdong-Hong Kong-Macao Greater Bay Area. The game has aroused wide concern at home and abroad. As a major emitter of carbon dioxide, the reduction of carbon emission have similarly drawn international attention. Based on this, this paper uses the quasi-natural experiment method to carry out an empirical test of the carbon emission reduction effect of the 2010 Asian Games based on an urban panel data from 2005 to 2019, aiming to provide reference for the carbon neutral management of the 15^th National Games. The empirical results are as followed. ①The carbon emission reduction effect of the host city was significantly greater than that of the co-host city. ②Hosting the Asian Games had positive influence on the carbon emission reduction performance by optimizing the road traffic system and promoting the upgrading of industrial structure, but had negative influence by establishing tourism city brand. ③With the improvement of regions' technology level and residents' educational level, the carbon emission reduction effect of hosting the Asian Games is becoming more and more significant. The paper proposes to take low carbon supply and low carbon demand as guidance to provide reference for accelerating the realization of carbon reduction in the 15^th National Games.

The 15^th National Games serve as an important means to promote the micro-renewal of cities in the Guangdong-Hong Kong-Macao Greater Bay Area. By applying research methods such as literature review and logical analysis, this paper studies the historical experience, theoretical mechanism and practical approach of the 15^th National Games in promoting urban micro-renewal. Research suggests that since the new era, the National Games have conducted practical explorations on the coordinated mechanism of event preparation and urban renewal, the collaborative path of venue construction and the activation of urban existing space, the experience and enlightenment of the balance between continuous event investment and social benefits, and the integrated practice of the implantation of sports spirit and the inheritance of local cultural context. The 15^th National Games mainly promoted the micro-update of the governance system through the upgrading of event organization, the micro-update of the built environment through the construction and renovation of venues, the micro-update of industrial functions through the injection of sports capital, and the micro-update of community culture through the development of mass fitness. Based on the actual development of the Guangdong-Hong Kong-Macao Greater Bay Area, it is proposed to innovate the collaborative mechanism and break through the governance barriers of cross-border renewal, unleash the momentum of the event and activate the functions of the remaining space after the competition, integrate green intelligence and reconstruct the spatial network of ecological cities, deeply cultivate the sports genes and carry forward the cultural heritage of Lingnan.

Against the dual backdrop of deepening national strategies and regional governance transformation, the National Games have gradually evolved into an institutional carrier and practical platform for promoting urban modernization and high-quality development. Anchored in the theoretical perspective of holistic governance, this study employs literature analysis and logical induction to systematically examine the governance logic, operational mechanisms, and institutionalized pathways through which the National Games empower urban development. The findings reveal that large-scale sporting events contribute to urban development through governance logic centered on policy coordination, organizational logic underpinned by institutional integration, and practical logic characterized by cross-level, cross-sectoral, and cross-regional collaboration. At the operational level, the National Games have progressively established a holistic governance system driven by institutional embedding, resource integration, and process closure. At the pathway level, three institutionalized trajectories are identified—enhancing governance effectiveness, upgrading urban functions, and expanding social value—demonstrating the National Games' transformation from a temporary mobilization event into an institutionalized governance platform. The study concludes that holistic governance not only enriches the theoretical explanatory power of large-scale sporting event research but also provides practical references and academic support for the institutional design and governance optimization of future National Games.

The 15^th National Games, jointly hosted for the first time across Guangdong, Hong Kong, and Macao, presents unique challenges for cross-border data flow governance under the framework of "one country, two systems, and three jurisdictions." Through policy text analysis, literature review, and empirical case studies, this research constructs a three-dimensional governance model encompassing "Sovereignty Layering-Technological Empowerment-rule Coordination." The findings indicate that a four-tier data classification system (Core Data, General Data, Derived Data, Public Data), based on data sensitivity and sovereignty relevance, enables differentiated governance. A three-tiered governance gradient comprising Central oversight, Regional Collaboration, and Market-Driven value Conversion effectively balances data security and flow efficiency. Furthermore, technologies such as blockchain, federated learning, and secure computation facilitate secure data circulation under the principle of "usable but invisible data." This research provides a systematic solution for sports data governance within the Guangdong-Hong Kong-Macao Greater Bay Area and offers an innovative paradigm for global cross-jurisdictional data governance practices.

The 15^th National Games of the People's Republic of China, jointly hosted by Guangdong, Hong Kong, and Macao, is bound to become a strategic fulcrum for promoting regional coordinated development and deepening the integrated construction practice of the Guangdong-Hong Kong-Macao Greater Bay Area in the context of the new era due to its special geographical location. This paper, based on the multi-center governance theory, systematically examines the mechanism of action and practical path for promoting the in-depth "Five-in-One" integration of the Greater Bay Area through methods such as literature review and logical analysis. The research reveals that the sports interaction among Guangdong, Hong Kong, and Macao has gone through five development stages: emotional bonding, economic driving, institutional integration, deepening and expansion, and strategic integration, which reflects a profound transformation from separate control to strategic integration. The organizational structure of the 15^th National Games under the framework of "one country, two systems, and three legal regions" represents an institutional innovation for the Greater Bay Area to construct a collaborative governance model, and its value is manifested in five dimensions: politics, economy, culture, society, and ecology. However, the preparation for the Games faces structural challenges such as institutional differences, uneven resource allocation, divergence of values, obstacles to social integration, and lack of a sustainable mechanism. Accordingly, this paper proposes strategies such as improving the cross-regional collaborative governance mechanism, optimizing the allocation of regional elements, creating a shared cultural identity space, constructing a long-term exchange platform, and innovating a green and low-carbon model for hosting the Games, aiming to transform the 15^th National Games from a "one-time event" into a "sustainable platform" for promoting the in-depth integration of the Greater Bay Area.

As the highest-level and largest-scale comprehensive sports event in China, the National Games have witnessed and led the glorious journey of Chinese sports. The research holds that the theme slogan is the core carrier of the spirit of the National Games. It not only condenses the social demands of different historical stages but also profoundly reflects the evolution trajectory of China's sports industry. Since the theme slogan of the National Games was launched, it has mainly gone through three stages: "serving national construction", "demonstrating national strength"and "sharing development dividends". It is an objective portrayal of the changes in the background of China's sports development, a presentation of the evolution of China's sports development concepts, a code expression of the inheritance and innovation of the Chinese sports spirit, and a realistic carrier for guiding and mobilizing the dissemination of values. This is specifically reflected in the intrinsic value color of adhering to the Party's cultural and ideological guidance, the inherent value color of upholding the principle of "putting people at the center", the value expression quality color of conforming to the pace of the value shift in Chinese sports, and the value demonstration color of holding high the banner of innovation and characteristic development. This further highlights the leading role of the National Games in promoting the modernization process of Chinese sports.
