[Objective/Significance] This article systematically reviews and evaluates the research literature on the formation, evolution and governance of alliance portfolio,and points out the future research directions of alliance portfolio.This can enhance the understanding of alliance portfolio and provide some reference for scholars to grasp the research context and future research directions of alliance portfolio. [Method/Process] This article systematically reviews and evaluates the research on the formation, evolution, and governance of alliance portfolio. [Results/Conclusions] The researches on the causes of alliance portfolio are mainly based on theories and perspectives such as organizational learning theory, resource-based theory, resource dependence theory, social network theory, corporate governance, and entrepreneurial management. The characteristics of alliance portfolio are described using features such as quantity, relationships, structure, and partners. The alliance portfolio evolution process is influenced by external factors (such as external environment, technological shocks, etc.) and internal factors of the focus enterprise (such as strategy, resources, etc.), and is in a continuous evolution process. Therefore, the evolution of the alliance portfolio can be studied from the co-opetition perspective, power relations perspective, and resource views. The governance of alliance portfolio involves dynamic matching of alliance portfolio, and should adopt alliance portfolio governance mechanisms such as transaction governance and relationship governance, requiring the capability to manage alliance portfolio. Finally, this article discusses the research gaps on formation, evolution, and governance of alliance portfolio, and suggests some future research directions.

[Objective/Significance] By analyzing the research trends in the field of quantum materials, this study provides information support for research and management decision-making in the field of quantum materials. [Method/Process] This paper uses the Web of Science scientific citation index database as the data source and comprehensively applies various research methods such as bibliometrics, LDA topic modeling, and co-occurrence network analysis to conduct an in-depth analysis of the development trends, competitive situation, and key research topics in the field of quantum materials related to quantum information science. [Results/Conclusions] The research on quantum materials related to quantum information technology is still in a stage of rapid development, and the number of related research shows a steadily rising trend. A new research peak may not have yet formed; the United States, China, Germany, and Japan are the main countries conducting research in this field; research institutions are relatively dispersed, with universities having the largest proportion; in terms of research topics, the main focus on superconductivity and other mainstream materials, two-dimensional materials and other emerging materials, as well as the underlying key quantum technology; China's rapid development in recent years, but the research accumulation is weaker than the United States, for example, superconducting materials, quantum dots, topological quantum materials, diamond, silicon materials, and other directions compared with the United States there is still a certain gap; China's advantageous organizations should continue to play a leading role in the application of technology, accelerate the development of quantum information industry, the underlying key materials and key basic technology research and development.

[Objective/Significance] In view of the strategic requirements of intellectual property power and the important position of new material industry in the future development of high-tech industry in China, this paper aims to explore the spatial distribution characteristics and spatial-temporal dynamic evolution trend of high-value patents in China's new material industry, to enrich high-value patent research and offer targeted advice for new material industry development, so as to help China win the initiative in the strategic competition of new material industry in the future. [Method/Process] This paper collects high-value patent data of new materials industry in 30 provinces(autonomous region,municipality) in China from Wisdom Sprout Patent Database from 2011 to 2021, and uses exploratory spatial data analysis, Dagum Gini coefficient, and spatial Markov modeling methods to explore the spatial distribution characteristics and spatial dynamics of the high-value patents of China's new materials industry. [Results/Conclusions] High-value patents in China's new materials industry are characterized by spatial aggregation, and the positive spatial correlation is increasing; the overall spatial gap is narrowing but there is still a large gap, and the gap between various regions is the main reason for the overall gap is too large; in the spatial evolution of the Chinese new materials industry, the development of high-value patents exhibits a phenomenon of "club convergence". Regarding the migration of development levels across regions, the probability of upward transfer is greater than that of downward transfer, indicating an overall trend of stable and positive development.

[Objective/Significance] Basic research serves as the linchpin for addressing fundamental scientific inquiries, playing a pivotal role in advancing science and technology and enhancing original innovation capacities within China. [Method/Process] This study introduces the Comprehensive Competitiveness Index of Urban Basic Research, employing methodologies such as the Theil index and spatial Markov chain analysis to explore the spatiotemporal evolution patterns and influencing factors shaping the comprehensive competitiveness of urban basic research in China from 2010 to 2019. [Results/Conclusions] The analysis reveals several key findings as follows: The comprehensive competitiveness of urban basic research in China exhibits an inverted "L" shaped evolution, characterized by an initial rapid surge followed by subtle fluctuations. Regions with high competitiveness are predominantly clustered in provincial capitals and municipalities directly under the central government, illustrating distinct spatial heterogeneity. Local spatial autocorrelation is observed in the comprehensive competitiveness of urban basic research, with regional disparities primarily stemming from internal differences within each region. The state transition probability of comprehensive competitiveness in urban basic research demonstrates significant stability and "club convergence" characteristics, with geographic proximity playing a substantial role in facilitating or impeding state transitions. Research suitability emerges as the foremost influencing factor on the comprehensive competitiveness of urban basic research, with core explanatory variables correlating in the following order: number of universities, proportion of secondary industry in GDP, PM_2.5 concentration, average temperature, number of granted patents, and library collection size.

[Objective/Significance] To comprehensively review the research status and trend of global commercial space industry, reveal the evolution of global commercial space patent technology, and provide reference for the research and development of domestic commercial space industry. [Method/Process] Based on the data of 6493 Web of Science articles and 8663 patents, this paper used the bibliometric analysis method, patent index method and S-curve method to discuss the annual distribution, country distribution, institution distribution, research hotspots and frontier fields of the global commercial space research. The life cycle changes of patent technology in the field are analyzed. [Results/Conclusions] Since 2000, the annual number of global commercial space publications has shown a significant upward trend. The United States leads in commercial space literature publication and cooperation network, while China ranks second in publication volume, but international cooperation needs to be strengthened. Keywords such as satellites, low-Earth orbit and remote sensing have become new research hotspots, and emerging technologies such as deep learning are merging with commercial space at an accelerating pace. The analysis of patent indicators and S-curve predicts that the next 5-10 years will be a critical period for the rapid development of commercial space from the growth period to the maturity period. We should seize the opportunity to lay out the patent technology fields of commercial satellites and commercial rockets, actively expand new scenarios for the application of communications, navigation, remote sensing, and explore the public service fields of satellite applications, and accelerate the industrialization of commercial space.

[Objective/Significance] Policy theme research has become an important direction in the field of library and information technology. Sorting out its dynamic frontiers can provide reference for domestic research. [Method/Process] This study systematically sorted out the hot research and cutting-edge evolution trends of policy topics in the field of library information at home and abroad through keyword emergence analysis, time evolution analysis of keyword co-occurrence and comparison with domestic and foreign research results. [Results/Conclusions] The results show that: Domestically, we focus on information policy, policy tools, libraries and library law, scientific data, open data, comparative analysis of domestic and foreign policy studies; Internationally, researchers focus on technical methods and innovative research directions in the fields of communications technology policy and the digital divide, information access and privacy protection, data openness and government decision-making, and science policy; China is in a stable development stage in policy-themed research. It can expand the breadth and depth of domestic research by integrating information resources across disciplines, focusing on the practical application value of research results, expanding international research perspectives, and promoting open access to scientific data.

[Objective/Significance] In order to make the evaluation of scientists obtain higher social recognition and establish "trust of scientists", this paper studies the public's recognition of the evaluation quality of scientists and its influencing factors from the perspective of the public. [Method/Process] The research model is constructed according to the information reception theory, the data is collected through network survey, and the data is analyzed by structural equation model. [Results/Conclusions] The results show that: the sample population has a high recognition of the list of top scientists in the world; Review data, evaluation indicators, review procedures and review experts have direct positive effects on the usefulness of scientists' review, and indirectly affect the recognition of scientists' evaluation quality through the usefulness of review. However, in this analysis, the influence of scientist level and review results on the usefulness of review has not been directly verified. Therefore, this paper draws three enlightenments: to improve the credibility of Chinese scientists' evaluation efficiently, and to build "scientists' trust"; Explore the effective path of the construction of new think tanks with Chinese characteristics; At the same time, it is suggested to formulate evaluation policies that can encourage excellent scientists in time, so as to promote the virtuous circle of individual scientists, science and technology and science policy.
