[Objective/Significance] Low altitude economy has not been around for a long time, but it has attracted the attention of academia. It is necessary to explore its research situation. [Method/Process] Taking 68 core literatures on low-level economy in CNKI database as samples, combined with Baidu Index to search for low-level economy keywords, using CiteSpace V, SPSS21.0, Excel2010 and other software and Baidu index analysis method for bibliometric and visual analysis. [Results/Conclusions] China’s low altitude economy is in the early stage of research, and the society has paid some attention to the low altitude economy, but the degree of attention is not high. Low altitude economic and social attention is closely related to the level of economic development and the level of low altitude industrial development. There is a significant difference between the demand profile of the search crowd and the characteristics of users throughout the network. The research results of low altitude economy show an increasing trend, but the research attention needs to be improved. The published journals are scattered, the core author group has not yet formed, and there is a lack of high-yield authors. Although low altitude economic research has a certain cooperation status, the overall cooperation scale is not large, and the cooperation team has not yet formed. Research hotspots mainly focus on the concept of low-level economy, high-quality development, technical support, driving factors, relationship with new productivity, impact effects, application scenarios, legal and security issues.

[Objective/Significance] As one of the core areas in national scientific and technological competition, analyzing the theme evolution rules and paths of China’s quantum research driven by policies is of great significance for optimizing academic layout and policy-making. [Method/Process] Drawing on relevant science and technology policies, this study utilizes 10558 Chinese quantum research articles from the Web of Science Core Collection as the data source. An LDA-SciBERT model is constructed and a topic heat indicator system is introduced to trace the evolution of research themes in China’s quantum studies and to examine the guiding role of policy in shaping research directions. [Results/Conclusions] Quantum communication has long dominated research, while emerging themes such as quantum computing and precision measurement have rapidly risen and shown a trend of multi-field integration. Quantum science and technology policies have gradually expanded from basic research to attaching equal importance to basic and applied research. Guided by relevant policies, China’s quantum research has gradually shifted from basic research to application orientation, demonstrating a high correlation between theme evolution and policy directions.

[Objective/Significance] The strategic level of digital economy development has been continuously elevated. Uncovering the policy information internalized in policy texts is of great significance for the formulation and improvement of digital economy policies. [Method/Process] A total of 152 policy texts on the digital economy issued in China from 2016 to 2024 were collected. Based on the policy tool theory, an analytical framework was established. The structure and distribution of digital economy policy tools were presented through policy text coding. The LDA topic model was utilized to mine policy hot topics, and the policy-making logic under different tool types was analyzed in depth. [Results/Conclusions] Digital economy policies cover multiple fields such as industry, services, and the Internet. The policies focus on five themes: industrial transformation and development, digitalization of public services, digital talent cultivation, digital economy security, and digital infrastructure. In terms of policy tool distribution, supply-type tools are overabundant, while the application of demand-type and environment-type tools is limited. However, there is a strong compatibility between policy tools and policy themes. Countermeasures and suggestions are proposed from aspects such as strengthening the rationality of the tool structure distribution of the digital economy, improving the planning and layout of policy themes, and deepening the precise matching of tools and themes.

[Objective/Significance] Quantum precision measurement and quantum sensing has been listed as one of the critical and emerging technologies by science and technology (S&T) advanced countries. The aim of this research is to provide information reference for China to obtain the leading strategic position in the area of science and technology (S&T) and accelerate the construction of a strong S&T country. [Method/Process] Based on the Incopat patent database and US Commerce Control List (CCL) data, combing qualitative and quantitative methods, this article analyzes the development trend of quantum precision measurement and sensing technology, global technology competition landscape, important research institution layout, key technology types, and US export control situation. [Results/Conclusions] Global quantum sensors and quantum precision measurement technology is still in the early stage of industrial development, with enormous potentials and broad market application prospects. However, it still faces some challenges in the process from research and development to industrialization. In addition to quantum sensors, lasers and advanced semiconducting technology are also key technologies of quantum precision measurement field, which also belong to the important content of the US export control technology to China. China’s quantum precision measurement and sensing technology has developed rapidly since 2008. The patent focuses generally align with the global trend, but the technological approaches are not entirely the same. China’s research and development institutions in the field are mainly composed of universities and research institutes, core components are highly dependent on other countries and the number of foreign and international patents is relatively small.

[Objective/Significance] To enhance the university research collaboration network, foster inter-institutional scientific cooperation, optimize collaborative innovation mechanisms, and promote synergistic progress in innovation and higher education. [Method/Process] Taking China’ s “Double First-Class” universities as research samples, this study integrates data from the CNKI and Web of Science (WoS) databases to construct a university research collaboration network from 2003 to 2023. Using social network analysis and a negative binomial gravity model, the study reveals the network’ s evolutionary characteristics and influencing factors. [Results/Conclusions]The overall network density of inter-university research collaboration increased from 0.062 to 0.353, indicating a progressively closer collaboration network. Degree centrality has increased, while betweenness centrality has decreased, reflecting strengthened direct collaboration among universities. Geographically proximate universities tend to collaborate more closely, though long-distance collaborations have gradually increased; universities with similar disciplines collaborate more frequently, and interdisciplinary collaboration is on the rise; there is a significant disparity in the number of universities within each collaboration subgroup, which has gradually become more balanced over time. Top-tier and comprehensive universities occupy core positions in the network, while universities with specialized or discipline-focused characteristics tend to be on the periphery. Top-tier and comprehensive universities exhibit higher degree and betweenness centrality, while specialized and discipline-focused universities show lower centrality; the gap in degree centrality between universities is widening, whereas the gap in betweenness centrality is narrowing, indicating a strengthening role of leading universities. The number of publications by collaborating universities, institutional proximity, and cognitive proximity are positively correlated with co-authored papers, while university tier and geographic distance are negatively correlated with co-authored papers. This study provides theoretical and empirical support for optimizing collaborative innovation mechanisms among universities.

[Objective/Significance] To explore China’s achievements and challenges in the field of scientific research paper publication, particularly the phenomenon of retraction and the research integrity issues it reflects, and to propose corresponding suggestions. [Method/Process] Using data from the Web of Science database and the Amend platform, this study analyzed the quantity, quality, and retraction status of scientific research papers published globally and in China from 2000 to 2023. Meanwhile, China’s efforts and achievements in building research integrity were comprehensively evaluated, considering various factors such as relevant policies, international cooperation and exchanges, early warning mechanisms, and disciplinary measures. [Results/Conclusions] China’s rapid development in the field of scientific research is remarkable, but issues of academic misconduct and paper retraction cannot be ignored. To further enhance the level of research integrity, it is recommended to strengthen research ethics education, establish a scientific talent and reward evaluation mechanism, enhance international cooperation and exchanges, and increase penalties.
