Abstract： Hypersonic technology is a key technology in the aerospace field in the future and is of very important strategic and forward-looking significance. Using bibliometric methods, it is found that research on hypersonic technology is mainly concentrated in the military field, among which power propulsion technology, navigation guidance and control technology, thermal protection technology and new materials are important research directions in this field. After sorting out the research and development situation of various countries, it is found that the relevant core technologies related to the development of hypersonic weapons are still the focus of future research. At the same time, accelerating the deployment of hypersonic defense systems and strengthening cooperation with partner countries in technology research and development, joint air defense and missile defense to enhance regional defense and deterrence are also priorities for future deployment of countries.

Abstract： As a strategic and policy research and decision-making consulting institution, the international influence of think tanks is an important manifestation of a country’s soft power and an important component of its comprehensive national strength in the era of globalization. Enhancing international communication power of think tanks is a key measure for shaping their international influence and an important strategy for a country’s external communication. In today’s era, international social media, as an important channel for think tanks to spread abroad, strengthening the communication power of Chinese think tanks in international social media is the main direction to enhance their international influence. This study analyzes the opportunities brought by the social media era to the international dissemination of Chinese think tanks, compares the differences between current Chinese think tanks and internationally renowned think tanks by using international social media for external dissemination, and then proposes effective approaches to enhance the international dissemination capacity of Chinese think tanks in the social media era based on the Chinese context. The results will provide reference and inspiration for the construction of international communication for Chinese think tanks, especially for enhancing their international communication power through international social media. This study finds that there is a certain gap between Chinese think tanks and foreign think tanks in terms of international communication power. In the social media era, it is recommended that Chinese think tanks consider the international communication ability of think tanks as an important component of their core business capability system, build and strengthen the four key networks of think tanks: ideology, resources, information, dissemination, and implement combination strategy of internationalization, openness, academic circle, circle of friends, ideological power, macro issues, social media, popular broadcasters to enhance the international communication power of think tanks.

Abstract： In the 21st century, a new round of world scientific and technological revolution and industrial transformation has accelerated. Especially after the international financial crisis, countries have strengthened their scientific and technological strategic layout and R&D investment. The international scientific and technological competition has become increasingly fierce, and science and technology policy has become a key factor determining the success or failure of technological competition. This study analyzes the historical evolution of policy documents such as science and technology planning, strategic guidelines and research reports issued by the U.S. government and the long-term R&D input data of the federal government in the past two decades, with a view to revealing the development and evolution characteristics of the U.S. science and technology policy, and thus providing a certain explanation for the relative decline of the U.S. science and technology leading position. It shows that the relative decline of the United States’ global leadership in science and technology is closely related to the relatively stable development of science and technology policies, the weakening of strategic leadership of major science and technology plans, the year-on-year decline of government R&D investment intensity and the decline of emphasis on frontier basic research. This has important implications for China’s scientific and technological development: scientific and technological development is not only a long-term strategic undertaking, but also a highly competitive undertaking. The improvement of scientific and technological competitiveness is the result of the national long-term scientific and technological strategy-oriented layout, the steady increase in R&D investment intensity and the accumulation of major scientific and technological innovation breakthroughs.

Abstract： In the era of digital economy, open source innovation has become the stimulator of innovation vitality, and is becoming an important source of high-quality supply of digital public goods. This study focuses on the importance of promoting the open source of state-funded scientific research projects, and summarizes the practical experience and policy measures of major countries and regions in the world on the open source of state-funded scientific research projects. It is also emphasized that the challenges of promoting the open source of state-funded scientific research projects in China. Suggestions for promoting the establishment of an open source mechanism of scientific research achievements are presented in this paper.

Abstract： Based on full investigation of the field of open publishing at home and abroad, this study expounds the role of open science in promoting the evolution of academic exchange system and mechanism, focuses on analyzing and summarizing the historical evolution, development change, and evolution law of academic publishing mode, and puts forward the meta-publishing concept that meets the needs of the open science era, so as to adapt to the development evolution and mode transformation of academic publishing. Based on the concept of “meta-publishing”, the idea of building a meta-publishing platform is proposed to promote the construction of a new paradigm of open science academic publishing led by the scientific community, integrating diversified publishing content, realizing multi-dimensional content association, aggregating multiple participants, and supporting the re-integration of scientific achievements. According to the design idea of the meta-publishing platform, MetaPub, a meta-publishing platform consisting of five modules, including structured publication engine, peer review subsystem, open publishing subsystem, knowledge discovery subsystem, and academic exchange community subsystem, has been built. The meta-publishing platform is a specific practice that is compatible with the development trend of open science and will play an active supporting role in the process of academic exchanges in the scientific community.

Abstract： Biotech seed industry is a strategic core industry. Biotechnology combined with digital technology has promoted the seed industry into an intelligent era, and the breeding paradigm has changed from “experimental selection” to “computational selection”. Biotech seed industry has become a research and development intensive industry, and the market is highly concentrated, which is controlled by large multinational enterprises. The scientific and technological output of China and the United States is in the first echelon, and the number of papers and authorized patents ranks among the top two in the world. From the perspective of core competitiveness, the United States is a global leader with monopoly advantages in original basic research and key technology. China has made great progress in the application of breeding technology, but it still needs to breakthrough in basic theory research, key technology development, and high value seed product.
