From a perspective of research output, this paper using bibliometric methods analyzes the following aspects for the field of Public Health Management: overall output, international collaborations, distribution of keywords and journals, interdisciplinary, research topics and hot topics, and funding papers, based on publications in Clarivate Analytics's Web of Science database. Combining experts’ views with bibliometric results, this paper aims to reveal the development trend of China and its international competitiveness in this field, and to provide references to policy formulation for Chinese government. The results show that, China has made some progress in this field, but still lagged behind compared with developed countries such as USA. The rank of China in publication volume, academic impact and the output of highly cited papers is 19th, 17th, and 13th respectively in 2009, and rises to 7th, 7th, and 10th in 2019. In addition, China locates in the periphery position in the international collaboration network, and the research funding of which, especially funding from NSFC, is not supportive enough for the output of highly cited papers, and needs to be more effective in the future.

Combining experts’ views with bibliometric results, this paper aims to reveal the development trend of China and its international competitiveness in this field, and to provide references to policy formulation for Chinese government. The results show that, China has made some progress in this field: the rank of China in publication volume, academic impact and the output of highly cited papers is 15th, 25th, and 26th respectively in 2009, and rises to 5th, 6th, and 6th in 2019, but still lagging behind compared with USA. In addition, China is getting closer to the center position of the international collaboration network, and the research funding of which, especially funding from NSFC, is not supportive enough for the output of highly cited papers, and needs to be more effective in the future.

This article reveals the trend of food science and technology research status, which provides a scientific basis for the scientific and technological development planning and industrial policy making in the food field. Taking Web of Science (WoS) core collection database as sample source, this article collects 37,606 research articles published in 34 journals in Q1 District of Food Science and Technology from 2017 to 2019, and applies CiteSpace software to analyzing the issuing institutions, the author distribution, the research directions and the funding institutions, the keywords co-occurrence and clustering, and high-impact articles so as to explore the innovation trend of food area. China is the country with the most journal research papers published in Q1 in the field of food science and technology as well as the high-level papers. The identification and efficacy of food functional ingredients are still the most concerned topics in the area, and the new technology of food processing and quality safety is the research hotspot in the area. In the future, the research channels of international scientific and technological cooperation is required and the interdisciplinary research and revolutionary innovation of technological methods are encouraged.

As a comprehensive resource, e-waste contains many precious resources. Resource utilization is an important way to solve the problems of resource shortage and environmental pollution. Based on the paper data collected in Web of Science Core Collection, this article analyzes the paper in the field of the e-waste resource utilization from 1994 to 2019. Using the Derwent data analysis tool (Derwent Data Analyzer, DDA) and VOSviewer software, it reveals the research status and evolution trend, major countries, leading research institutions, major co-authors, keywords, and highly cited papers in the field of e-waste resource utilization.

This paper aims to understand the development history of intelligent technology research in the field of Library-information-archive, and explore current research hotspots and future development trends. Based on the literature in CNKI, this paper used SATI, Excel and CiteSpace for data mining and knowledge mapping analysis. This paper shows the 3 stages of intelligent technology research development process in the field of library-information-archive, the evolutionary veins of research hotspots in various disciplines, the relationship network of researchers and research institutions, and the direction of the research field.
