The deep integration of information technologies and healthcare has become a prevailing trend. Digital healthcare, with its prominent advantages in optimizing the supply-demand matching of medical resources and enhancing the accessibility of health services, has emerged as a core driving force in the transformation of the healthcare service system. This study reviews the current development status and trends of digital healthcare in China, covering areas such as smart hospitals, proactive health, and public health. It identifies key challenges from the aspects of standardized data governance (involving data quality assurance and privacy protection in acquisition, as well as foundational computational power and analytical capabilities for data utilization), equitable access to digital and intelligent health services (involving fair availability and on-demand provision, reliable decision-making with trustworthy processes, and dynamic responsiveness with iterative evolution), and coordinated allocation of healthcare resources (involving effective intra- and inter-hospital collaboration and sharing mechanisms, as well as resource interoperability and process linkage for online/offline integration). To address these challenges, we propose (1) establishing a unified governance system for healthcare data and integrating cross-domain healthcare data under the Internet of Healthcare Systems (IHS) environment; (2) adopting equalization safeguarding strategies for healthcare services and developing secure and trustworthy foundational models for digital and intelligent healthcare; and (3) constructing coordinated mechanisms for healthcare resource allocation to connect multi-stakeholder resources across the entire healthcare service process. These measures aim to promote the compliant and efficient development of data, ensure equitable access to digital and intelligent services of smart healthcare, and achieve a balanced distribution of high-quality healthcare resources.
Promoting the sharing of high-quality medical resources is a major strategic initiative in China's healthcare sector, with digital health technologies emerging as a key facilitator in realizing this goal. In this paper, we examine the strategic values of digital health technologies in overcoming spatial barriers to healthcare access, optimizing resource allocation, and strengthening the capabilities of primary healthcare institutions. Representative applications of digital health based on technologies such as Internet platforms, mobile communication, big data analytics, artificial intelligence, and blockchain are discussed. However, several key challenges hinder the application of digital health technologies in advancing the sharing of high-quality medical resources, involving issues related to the supply, demand, and distribution of these resources. These challenges specifically include limited capabilities of primary healthcare institutions, underdeveloped digital security systems, low levels of digital health literacy among the public, and the complexity of the resource distribution process. In response, a comprehensive set of development strategies is proposed to advance the sharing of high-quality medical resources through digital health technologies. These strategies encompass five key areas: enhancing policy coordination and planning, improving digital infrastructure, deepening the integration of digital health technologies, supporting the development of primary healthcare institutions, and expanding access to digital health services. Collectively, these strategies provide theoretical foundations and practical guidance for promoting the collaborative sharing of high-quality medical resources.
The in-depth application of digital technologies in the medical sector is driving the transformation of medical institutions toward a more intelligent and data-driven approach. This study, based on the application framework of digital technologies, outlines their key application scenarios in medical service processes, explores their impacts on the operational mechanisms and service models of medical institutions, and analyzes the major challenges currently faced. The study indicates that digital technologies have been widely applied in various scenarios, including precision medicine and personalized treatment, medical research and education, patient service and experience optimization, health management, medical operation and administration, as well as medical equipment and facility management. However, the widespread adoption of digital technologies is still constrained by multiple factors, such as inadequate data security mechanisms, lack of a unified technological standards system, and outdated infrastructure. These issues, to varying degrees, hinder the sustainable development of digital technologies. In response, this study suggests that future medical institutions should strengthen the deep integration and continuous innovation of digital technologies, promote the transformation of medical models toward comprehensive health management, and advance the refinement and intelligence of management models. This will facilitate a profound transformation in medical cognition and health concepts, ultimately leading to the establishment of a digital and humanistic medical service system.
The rapid advancement of digital health technologies is facilitating a shift in health management from a reactive model to a proactive one. Grounded in the proactive health theoretical framework of "proactive sensing, proactive discovery, and proactive response," this study reviews the current application status, challenges, and future trends of digital health technologies in the field of proactive health. The study reveals that the application of these technologies in China faces multiple challenges, including limitations in sensing accuracy, data security risks, computational constraints, disconnections in model application, as well as regional digital divides and group-based technological disparities. Meanwhile, application trends are evolving toward full-lifecycle management, multi-dimensional data integration, upgraded demand for personalized services, expansion of remote scenarios, and ecological data sharing. Corresponding key technologies involve next-generation biosensing, multimodal data fusion and analysis, intelligent intervention and digital therapeutics, integrated remote medical platforms, and privacy-preserving computation technologies. To address these issues, this study proposes several targeted recommendations: improving the policy support system, strengthening core technology research, promoting equitable and inclusive technological development, establishing sound ethical standards and security mechanisms, and advancing the expansion of application scenarios along with industrial ecosystem integration. These recommendations aim to provide a solid theoretical foundation for constructing a technological pathway for full-lifecycle proactive health management in China, thereby offering key technical support, scientific decision-making basis, and practical safeguards for achieving the strategic goal of Healthy China and promoting population-wide health.
Digital healthcare is increasingly integrating next-generation information technologies, accelerating the intelligent transformation of healthcare services. Physiological and psychological sensing, a core technology underpinning personalized health management, chronic disease monitoring, and precision medicine in digital healthcare, is advancing rapidly toward multi‑scenario integration and full‑lifecycle coverage. This study reviews its development across routine contexts such as households, communities, and medical institutions, as well as specialized domains including spaceflight, aviation, and maritime settings. It further examines core challenges in four dimensions: safety, convenience, intelligence, and human-centered care. To support sustained advancement, we propose five suggestions: establishing trustworthy data circulation and privacy protection systems, enhancing system adaptability and service responsiveness, strengthening knowledge integration and precise decision-making, embedding human values and population-level adaptability, and fostering coordinated development of key technologies. These efforts aim to enable continuous, precise, lifecycle healthcare services and drive collaborative innovation and deep transformation of the digital healthcare system.
The medical field is undergoing an intelligent transformation characterized by the emergence of multimodal foundation models. While technological empowerment brings unprecedented opportunities, it is accompanied by profound ethical risks. The deep application of medical foundation models has amplified such risks, necessitating comprehensive identification and effective governance strategies. This study systematically examines four core categories of ethical risks in medical foundation model applications: data privacy risks, algorithmic decision-making risks, subject-relation risks, and social equity risks, illustrated through representative cases. To address these challenges, a data‒algorithm‒application‒law integrated governance framework is proposed, encompassing the establishment of robust data governance systems, innovation of algorithmic governance mechanisms, formulation of clinical application standards, and improvement in legal and regulatory frameworks. Furthermore, the study analyzes key technological and policy challenges constraining the development of medical foundation models. Looking ahead, the study outlines potential future directions, including the exploration of blockchain-based medical data ownership confirmation, development of lightweight models to promote equitable healthcare at the grassroots level, and construction of collaborative ecosystems integrating government, industry, academia, research, and healthcare. These efforts are intended to provide theoretical foundations and practical pathways for fostering the normative and sound development of medical foundation model technologies, ensuring patient rights, and enhancing the ethical governance system in the healthcare domain.

Proactive health refers to a health paradigm, lifestyle, and cultural approach in which individuals take primary responsibility for their own well-being by enhancing health awareness, leveraging health technologies, and actively promoting their well-being. Together with medical services, disease prevention, and the Traditional Chinese Medicine concept of "preventive treatment," proactive health constitutes an integrated health protection system. Nearly forty years after the concept was first introduced, proactive health in China remains at the stage of research and demonstration, with limited public participation and underdeveloped systems for related technologies, industries, services, and policies. Currently, the promotion of proactive health in China faces five major challenges: weak public awareness, insufficient technological capacity, inadequate health protection for key populations, limited support for coping with population aging and chronic diseases, and an incomplete policy framework. This study suggests that advancing proactive health in China serves three major purposes: safeguarding public health, promoting economic development, and contributing to national revitalization. The essence of proactive health lies in individuals actively promoting their own health through a "whole-population, whole-life-cycle, and whole-factor (lifestyle)" approach. Its goal is to "prevent disease, delay disease onset, and reduce disease severity." The guiding principles are "individual responsibility, government leadership, social participation, innovation-driven development, and international cooperation." The six pillars of proactive health are diet, physical activity, lifestyle, health management, psychological and moral well-being, and living environment. During the 15th Five-Year Plan period, key tasks for advancing proactive health include strategic innovation, technological innovation, institutional and mechanism reform, and service model innovation; fostering the integration of public initiatives and industrial development; and strengthening international cooperation. These efforts aim to accelerate the transition of proactive health from research and demonstration to broad social practice, enhance population health, ease healthcare system burdens, and explore a Chinese model of health that integrates traditional Chinese and western medicine as well as proactive health and medical security.
The biopharmaceutical industry, serving as the core driving force in the realm of modern medicine, assumes an irreplaceable role in safeguarding national health, propelling economic development, and fostering technological advancements. When juxtaposed with the global vanguard of pharmaceutical innovation, China’s pharmaceutical industry still exhibits a notable generational disparity in terms of innovation capabilities. This study analyzes the current development status of China’s biopharmaceutical industry, delving into the issues and challenges encountered during its development. It also examines the development trends and competitive landscape of the international biopharmaceutical industry. Subsequently, considering China’s national circumstances, this study proposes development strategies and policy recommendations for the biopharmaceutical industry in several aspects. These include intensifying policy support, bolstering innovation-driven impetus, strengthening talent cultivation, optimizing the industrial chain, and enhancing international cooperation. The overarching aim is to facilitate China’s transition from a large biopharmaceutical nation to a strong biopharmaceutical power, thereby offering the public more high-quality, efficient, and accessible medical services and contributing to the construction of the Healthy China initiative.
The health system in China has progressed to a new phase of development; however, it continues to face challenges such as uneven distribution of resources and insufficient coordination among service sectors. It is imperative to enhance the health system's intrinsic capacity to identify and address problems. The research and implementation of the learning health system (LHS) concept are expected to play a pivotal role in promoting evidence-based policy formulation and implementation, as well as improving preventive services and clinical care. This study offers a comprehensive overview of the conceptual characteristics and application contexts of LHS. It outlines both domestic and international advancements in refining data analysis and the evidence application cycle, and reviews progress in practical applications, including quality measurement and improvement of care. Drawing upon the features and current status of China's health system, the study discusses foundational components and implementation strategies for establishing an LHS. These strategies emphasize strengthening the research capacity of leading institutions and the application capacity of professionals; enhancing data resources from hospitals, health administration, and health insurance; developing technological platforms for data acquisition, governance, utilization, and sharing; and conducting outcomes research and implementation research. Furthermore, the study evaluates the practical outcomes of two initiatives: the use of administrative data for quality measurement of care and the integration of Internet Plus in quality improvement of care. Looking ahead, the development of LHSs can be further advanced through the application of novel technologies and expansion into new domains. Such progress is anticipated to enhance the quality and efficiency of data governance, analysis, decision-making, evidence dissemination, and feedback monitoring, as well as to strengthen policy development and implementation, as exemplified by learning-based disease surveillance.
Promoting inclusive health in low-resource settings is an essential path toward achieving a higher level of health equity. Building upon a clarification of the fundamental concept of inclusive health in low-resource settings and the construction of an analytical framework, this study reviews international practices and identifies six key developmental patterns: governance mechanism innovations that drive resource optimal allocation; health-oriented payment reforms based on diversified and integrated financing models; integrated health service models grounded in supply-demand coordination and collaboration between primary and specialized care; systematic, practice-oriented training systems for general practitioners; practical and flexible production and supply chains for medicines and medical devices; and pragmatic and context-adapted integration of digital-intelligent technologies. The study argues that inclusive health in low-resource settings not only helps maintain social stability but also activates endogenous regional development potentials, making it an inevitable requirement and essential component of an inclusive social welfare system. In the context of global‒local interactions, pathways to inclusive health exhibit significant regional variations and face the core challenges of institutional coordination and technological adaptability. It is therefore recommended that China build an appropriate inclusive health system in a phased manner, focusing on supply-demand synergy and the integration of general and specialized care. Efforts should focus on establishing an integrated governance framework characterized by multi-stakeholder collaboration and digital-intelligent empowerment, with priority given to innovating core mechanisms of primary health care services and promoting the application of digital-intelligent technologies. This approach will facilitate efficient transformation of health resources and foster a virtuous cycle of regional development, particularly in low-resource settings.
Geological work is a vital precursor and foundational component of national economic and social development. In the face of unprecedented global and historical transformations, how China's geological efforts can adapt to these changes and support economic and social progress has become a major question of our time. This study analyzes the emerging global trends confronting geological work across the dimensions of resources, spatial planning, ecology, and technology. Geological survey agencies in major countries around the world are meeting the development needs of strategic emerging industries by conducting surveys and assessments of clean and low-carbon energy and critical mineral resources. Through environmental geology surveys, geological hazard investigations, and related work, they are promoting sustainable economic and social development. By applying information technologies such as big data and artificial intelligence, they are reshaping modern geological practices. Meanwhile, by strengthening interdisciplinary integration, they are advancing the Earth system science. Based on the actual geological work in China, the following development suggestions are proposed: (1) based on the traditional geological work in the field of mineral resources, strengthening the research on the supply of energy and mineral resources under the climate and geopolitical constraints; (2) solving the problems of water resources, water ecology, and water disasters under the conditions of climate change; (3) promoting geological disaster survey and research to support services for disaster prevention and mitigation and territorial spatial planning; (4) providing systematic geological solutions for the construction of resilient cities; (5) strengthening the research on marine geological survey for the construction of a strong ocean country; (6) strengthening the ecological geological surveys to guarantee the bottom line of ecological security; and (7) building a new system of geological science and technology that combines deep geological exploration and research with shallow geological process survey and research.
Critical metal minerals, such as rare earths, tungsten, antimony, cobalt, lithium, and tantalum, play a vital role in safeguarding national economic stability and defense security. With escalating global demand and intensifying competition for these resources, establishing a robust critical metal mineral reserve system has become a priority for China to ensure supply stability, protect resource security, and support high-quality industrial development. This study clarifies the scope of critical metal minerals, reviews reserve policies and operational frameworks of major international players, and analyzes China's current reserve system, covering top-level design, operational mechanisms, reserve potential, storage infrastructure, and civilian stockpiles. Moreover, it identifies key challenges: misalignment of reserve scales with resource security needs, inadequate standardization of reserve release procedures, ambiguous rights and responsibilities of designated reserve enterprises, and underdeveloped risk early-warning mechanisms. To address these gaps, the study proposes strengthening legislative frameworks for critical mineral reserves, expanding stockpiles of supply-constrained metals, optimizing dynamic reserve mechanisms, and establishing a nationwide monitoring, early-warning, and dynamic assessment system. These recommendations ultimately aim to fortify resource security, enhance industrial chain resilience, and provide safeguards against international market volatility and sudden supply disruptions.
The stable supply of tin resources is crucial for the development of China's information industry and strategic industries, serving as a key for strengthening the manufacturing sector and promoting digital economy innovation of the country. Currently, China's demand for tin resources continues to expand; however, domestic tin resources discovered through exploration are insufficient to satisfy the consumption demand, leading to a continuous increase in imports. Therefore, ensuring the security of the international supply chain of tin resources has become increasingly important. This study evaluates the security level of the international supply chain from three dimensions: resource supply, trade circulation, and recycling, providing scientific support for ensuring the security of tin resources in China. The findings indicate that China's tin supply chain displays a V-shaped risk profile; however, there are issues such as insufficient diversification in the supply of tin resources, slow growth in domestic tin reserves, subpar mineral processing technologies, inadequate recycled tin production, and persistently low recycling rates. This research suggests that China should enhance the stability of international supply chains, strengthen domestic resource security, and improve the system for the recovery of secondary resources. These measures are expected to accelerate diversification in external procurement, increase domestic investment in tin ore exploration and beneficiation development, and optimize the strategic reserve layout of tin resources, thereby comprehensively boosting the supply capacity and safety assurance of tin resources in China.
Nickel, cobalt, lithium, and vanadium are critical minerals underpinning China's new energy industry. However, they currently face triple challenges: resource shortages, poor natural endowments, and technological bottlenecks in high-value utilization. To clarify the development trajectory of the entire industrial chain, this study systematically examines the global resource distribution of nickel, cobalt, lithium, and vanadium and reviews the current status of mining, beneficiation, smelting, and recycling technologies. It summarizes China's strengths and remaining weaknesses across these four chains and proposes priority tasks and policy recommendations for the next stage. The study finds that although China has built the world's most complete industrial chains for nickel, cobalt, lithium, and vanadium, upstream supply-security risks remain significant, import dependence is high, and competitiveness in high-end materials technology is still insufficient. Therefore, the study designs a resource-security roadmap and key tasks targeted for 2035, including establishing a mineral "gene" database, advancing comprehensive utilization technologies for low-grade resources, developing high-quality material technologies and products, building a green recycling system, and creating an innovation platform spanning the full chain. Finally, tailored countermeasures and suggestions are proposed for the nickel–cobalt, lithium, and vanadium chains to promote steady industrial development, aiming to provide a solid resource support for the high-quality and sustainable growth of China's new energy sector.
Nuclear energy, characterized by cleanliness, low carbon emissions, stability, high efficiency, high energy density, and suitability as a baseload power source, has become an essential element of the energy strategies in many countries. The development of nuclear power is of crucial importance for China’s transition in energy structure. Despite global trends and China’s leading position in installed nuclear capacity, the country has not yet commenced the construction of nuclear power plants in inland regions. There is an urgent need to clarify the feasible pathway and development plans for inland nuclear power. This study systematically analyzes and makes the case for resuming the construction of inland nuclear power plants, focusing on two key dimensions—strategic necessity and technical feasibility—in conjunction with the newly released “Regulations for environmental radiation protection of nuclear power plant” (GB 6249—2025). The study concludes that developing inland nuclear power is both highly necessary and urgent in terms of safeguarding national energy security, constructing a new power system, and advancing regional strategic implementation. Concurrently, China’s mature third-generation pressurized water reactor technology provides reliable assurance of environmental safety for inland sites, demonstrating technical feasibility for inland deployment. It is recommended that inland nuclear power be included in the 15th Five-Year Plan, with the establishment of a dedicated research program focused on the treatment and discharge technologies for tritium and carbon-14 nuclides, and that demonstration projects for inland nuclear power be initiated in a timely manner. Meanwhile, supporting laws, regulations, and public communication mechanisms should be continuously improved. Promoting the scientific and orderly development of inland nuclear power will inject strong momentum into China’s transition toward green and high-quality energy development.

With the intensification of population aging, increasing environmental risks, and evolving disease spectra, the incidence of major chronic diseases in China continues to rise. Addressing this challenge requires the adoption of advanced technologies to enable early screening and diagnosis, precision treatment, and effective intervention. As an essential multidisciplinary and integrative technology, particle accelerators have become deeply embedded in key life and health scenarios, such as radiation diagnostics, radiotherapy, radiopharmaceutical production, and irradiation sterilization, demonstrating significant potential for functional expansion and system integration. This study reviews the technical characteristics of particle accelerators and classifies five representative application scenarios in the life and health field. It summarizes the current progress, frontier trends, and strategic directions of accelerator applications, and analyzes the major challenges from the technological, application, and policy dimensions. Based on this, the study proposes several key development priorities, including the autonomous and intelligent development of diagnostic accelerators, domestic substitution of therapeutic accelerators, integrated deployment of nuclear medicine accelerators, and construction of medical platforms centered on accelerator technologies.

These efforts will advance the technological innovation and application expansion of particle accelerators in the life and health sector, and enhance China’s independent innovation capacity in high-end medical equipment.
There has been a broad consensus on strengthening the supervision of cross-border data flows and promoting international cooperation. However, the importance attached to the governance of cross-border flows of industry-specific data is still insufficient, exhibiting a tendency for regulatory rules to be "one-size-fits-all". There is an urgent need to conduct targeted research to help solve the current governance dilemma. This study sorts out the core concepts and types of cross-border flows of industry-specific data, as well as characteristics and governance needs of cross-border data flows in typical industries such as finance, medical care, manufacturing, and e-commerce. Moreover, it analyzes the international mainstream paradigm of cross-border data flow governance and the policy practices in developed economies. The current situation and challenges of cross-border data flow governance in China are revealed. The study finds that the common trends in global cross-border data flow governance are becoming increasingly prominent, shifting from the tripartite structure of "sovereignty protection, free flow, and balanced governance" to "controlled flow" with security as a prerequisite. The basic system and industry rules for China's cross-border data flow governance have taken shape. However, there still exist problems such as ambiguities in industry risk gradients and a tendency toward "pan-security", difficulties in adapting emerging technologies and a disconnect between technologies and rules, insufficient departmental coordination and lagging regulatory responses, as well as fragmented rules and limited international discourse power. The study suggests improving the governance system for cross-border data flows, deepening participation in international data governance rules, strengthening refined regulatory mechanisms by industry, and building a collaborative governance ecosystem for cross-border data flows. This "China path" for the governance of cross-border flows of industry-specific data should be explored with equal emphasis on security and development.
With the deepening implementation of major aerospace projects, large and complex spacecraft are evolving toward larger scales, higher performance, and multi-payload integration, leading to increasingly complex on-orbit dynamics issues. This study focuses on the field of dynamics for large and complex spacecraft, systematically reviewing the research team's technological breakthroughs and engineering practices during the 13th and 14th Five-Year Plan periods of China. Driven by the engineering application demand for typical payloads such as large deployable antennas, laser communication terminals, and large optical cameras, key technologies were addressed, including nonlinear modeling and model reduction for flexible dynamics of large-aperture annular antennas, high-fidelity modeling and efficient simulation of on-orbit deployment dynamics for large space structures, micro-vibration assessment of high-precision and high-stability payloads under multi-source disturbances, rigid‒liquid‒flexible coupled dynamics modeling and simulation, and system-level thermal deformation modeling and simulation. An integrated simulation software system for the dynamics of large-scale complex spacecraft, with independent intellectual property rights, was developed. These achievements have been successfully applied in the engineering development of satellites with large deployable antennas, high-resolution optical remote sensing systems, and inter-satellite laser communications, and have been validated through ground tests and on-orbit flight experiments. Furthermore, considering the needs of current engineering development for large and complex spacecraft and the future development of new spacecraft, technical research directions in system design, dynamics and control, verification, and prediction are outlined. The relevant content are expected to provide references for guiding spacecraft design and on-orbit operations, as well as addressing future dynamic challenges in complex space systems.

Photovoltaic (PV) buildings generate electricity through their surfaces, which can reduce carbon emissions during operation by over 30%. The urban PV building industry in China has vast potentials for development. Driven by the carbon peaking and carbon neutralization goals as well as the demand for urban renewal, the industrialized development of the industry holds significant importance for energy transition and carbon reduction in the construction sector. This study analyzes the technical principles and development values of PV buildings, sorts out the current industrialization status of these buildings from the aspects of industrial scale, pattern, policies, and standards. It also identifies the challenges faced by the industrialization, including systematic inadequacy of policies, bottlenecks in technology integration, imperfect market mechanisms, and weak infrastructure. The study further summarizes the key links for industrial development, namely constructing a PV building model suitable for urban renewal, integrating PV buildings into the urban planning system, building a digital urban energy coordination platform, and upgrading the new urban power infrastructure. Using typical PV building projects as cases, this study empirically analyzes the technical and economic feasibility of urban PV building models, and further proposes the following suggestions for the high-quality industrialization of the urban PV building industry: strengthening top-level design and policy coordination, advancing system integration technologies to improve cluster efficiency, improving the market ecosystem to form multi-faceted support, and promoting the implementation of demonstration projects integrated with urban renewal.
New energy sources represented by wind and solar power are gradually reshaping China's energy consumption structure and driving the transition of China's energy system toward a green and low-carbon orientation. This transformation accelerates the formation of a regionally coordinated development pattern within the new energy industry, which is of great significance for ensuring national energy security and achieving the carbon peaking and carbon neutralization goals. Based on a systematic analysis of the intrinsic requirements for regional coordination in China's new energy industry, this study identifies the current situation and major challenges of regional collaboration, and proposes targeted development pathways and key measures. The findings indicate that the regional collaborative development of China's new energy industry faces multiple challenges, including spatial mismatches between energy resource supply and demand, spatial fragmentation along the upstream and downstream segments of the industrial chain, and intensified international energy competition. Moreover, significant challenges remain in the construction of basic and supporting projects as well as market systems that underpin the integrated development of "generation–grid–load–storage–data". To address these challenges, this study adopts a systems-thinking framework featuring "full-chain integration, full-space linkage, and whole-process optimization," and proposes a coordinated development pathway focusing on intra-regional optimization and inter-regional collaboration. The research highlights four key directions for technological breakthroughs—resource development, power transmission and dispatching, demand response, and market transactions—and promotes innovative integration and demonstration of "generation–grid–load–storage–data" systems. Policy recommendations include: promoting the rational layout of large-scale wind and solar power bases according to local conditions; strengthening coordination across inter-regional, provincial, and local grid dispatching; enhancing the intelligence and normalization of demand response mechanisms; and improving market connectivity throughout the entire "design–operation–certification" process. These recommendations provide strategic insights and practical guidance for advancing the regionally coordinated and high-quality development of China's new energy industry.
