    To address climate change, major countries/regions are encouraged to launch green New Deals facing carbon neutral long-term vision by 2050. Based on the DIIS think tank research theory, the study constructs a three-dimensional model framework of policy analysis of essential policy tools, industrial development cycle and technological innovation. It quantitatively analyses the policy content of carbon-neutral and green new policies in developed countries/regions. It reveals various countries main characteristics and development trends of carbon-neutral and green actions in. It is found that countries lay particular stress on the use of supply-oriented and environmental policy tools, while demand-oriented policies are lacking, and the tax mechanism, long-term binding force and pulling policy of their green new policy are insufficient. Most policies focus on the stage of technology development and demonstration and large-scale application, while there are few supporting policies for basic research and experiment; Carbon emission reduction technology and digital cross-technological innovation have become the focus of green new approaches in various countries, while there is a big gap in policy support for negative emission technology. It is suggested to continue to strengthen the intensity of green capital investment in the goal of carbon peaking and carbon neutrality, make appropriate use of policy tools of supply promotion, environmental support and demand-pull, and increase the application support of renewable energy, electric vehicles and other competitive clean industries. We will promote the orderly development of key future industries in the early stages, such as resource recycling, decarbonization of industrial processes, green hydrogen, zero-carbon ships and aircraft, and strengthen technological innovation in carbon reduction, negative emissions and cross-cutting fields.

    Unlike traditional research results, the potential intelligence in data of funded projects is more strategic and forward-looking. This paper used text mining methods to analyze the data of funded projects in the field of deep learning between China and the United States, from the funding intensity, development trend, topic clustering, and evolution, and compare the similarities and differences of research hotspots in the field of deep learning between two countries, hoping to provide a reference for future scientific research layout in China. This study found that the number of fund projects in the field of in-depth learning in China and the United States has increased since 2010, with a good development momentum, and both countries have issued policies to support the development. However, China and the United States focus on different research directions. The United States focuses on the basic theory and algorithm research of deep learning, while China pays more attention to implementing application levels in deep learning. On the application level, the United States spends more attention to biomedical, economic, image recognition and hardware equipment applications. China pays attention to the biomedical field and uses deep learning related algorithms to apply more data in the geoscience and multimedia fields. In the emerging research direction, the research on hardware equipment and the application of deep learning has become a hot topic in the United States in recent years, while the new research focus in China is to apply deep learning to bioinformatics.

    In order to cope with global warming and reduce CO2 emissions to the atmosphere, CO2 capture has become a key technology for global research. Based on the research status of CO2 capture technology at home and abroad, this paper divides CO2 capture technology into four technical routes: pre-combustion capture, post-combustion capture, oxyfuel combustion and chemical looping combustion. Pre-combustion capture and post-combustion capture technology mainly include absorption method, adsorption method, membrane separation method, low temperature fractionation method and other methods. Firstly, the research status and application progress of different methods of these four technical routes are summarized, and the future development trend of each technical method is proposed. Subsequently, the advantages and disadvantages of different CO2 capture technologies are compared. It is found that each technical method has its own advantages and disadvantages, and no technology can independently meet the requirements of high efficiency, low cost, low energy consumption and large scale. Finally, it is proposed that in the future, we should focus on the problems and challenges of CO2 capture technology, focus on research and development, break through the bottleneck at this stage, and promote the economy, efficiency and scale of CO2 capture.

    Synthetic biology is known as the frontier technology that subverts the future. Clarifying the strengths and weaknesses of synthetic biology between China and the world’s S&T powerhouses is conducive to adjusting and optimizing the scientific and technological innovation structure, meanwhile helping grasp the key fields of discipline development. We conduct topic mining and identify research hotspots based on paper data in the field of synthetic biology, generating time-series data about the development trend of S&T powerhouses’ research hot topics. Combining the grey correlation degree and Euclidean distance, this paper puts forward the correlation strength measurement index and introduces the basic idea of cross correlation method to analyze the lead-lag relationship and the time lag between China and the world’s S&T powerhouses. The research shows that the trend of research topics among various countries is closely related. A time lag phenomenon is observed that the development of synthetic biology in China is left behind compared with foreign countries. The United States, Britain, and Germany have shown relatively outstanding scientific research strength and are maintaining the leading position. The paper suggests that our country continues to improve the efficiency and quantity of research output. We should intensify our efforts in gene expression regulation and genome engineering and maintain the previous advantages of metabolic engineering research.

    Genetically modified (GM) insect-resistant maize has a good prospect of commercial application in China. The patent layout analysis was carried out to clarify the global research and development (R&D) pattern of GM insect-resistant maize technology, understand the technology development trend, and figure out the technical development gap in China to provide data support for rational deploying the technological innovation of GM insect-resistant maize, promoting its industrialization development in an orderly manner and improving the layout and protection of intellectual property rights in China. Based on the patent information, the global R&D pattern of GM insect-resistant maize technology was analyzed from the dimensions of the application year, region distribution and R&D subject by using the bibliometric method. The technical hotspots, development history and future development trends of GM insect-resistant maize technology were clarified through text clustering and technology development route analysis. The results show that the current research and development of global GM insect-resistant maize technology tends to be mature. The United States and China are the leading technology origin countries. The United States has significant advantages in patent scale, global layout and industrialization development. The international seed industry giants have enough patents and a comprehensive geographical structure. Expression vector construction is a key technical branch in the field. Chimeric genes composed of multiple insect-resistant genes and the combination of multi-insect-resistant gene expression cassettes are future development directions. There still exists a gap in the patent application number, global layout and industrialization development level of GM insect-resistant maize in China, with insufficient patent layout in the technical branch of expression vector construction and identification methods. It is suggested that China should emphasize gene expression vector construction technology to optimize the structure of technology research and development, actively cultivate the innovation ability of seed enterprises to strengthen its position as the main body of innovation and enhance the level of intellectual property protection and the strategic awareness of global layout.
