From a perspective of research output, this paper using bibliometric methods analyzes the following aspects for the field of Social Governance and Social Welfare: 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 shows a fast progress in publication volume, academic impact and the output of highly cited papers in this field. China ranks at 15th, 15th, 12th in the above three aspects respectively in 2009, and ranks at 4th, 6th, 4th in 2019, still lagging behind compared with USA. In addition, China is relatively active in international collaboration and the research funding of which, especially funding from NSFC, is also effective to some extent in this field.

From a perspective of research output, this paper using bibliometric methods analyzes the following aspects for the field of Regional Development and Urban Governance: 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 shows some advantages in 2009 and a relative fast progress afterward in publication volume, academic impact and the output of highly cited papers in this field. China ranks at 4th, 4th, 3rd in the above three aspects respectively in 2009, and ranks at 2nd, 3rd, 2nd in 2019, getting closer to USA in the three indicators. In addition, China is relatively active in international collaboration and the research funding of which, especially funding from NSFC, is also effective to some extent in this field.

This paper aims to analyze Nobel Prize-winning papers in Physiology or Medicine from the perspective of bibliometrics and explore the characteristics of representative papers. We introduced the citing papers indicators for supplementary evaluation. The key indicators were seclected to provide reference for the selection of representative papers. We searched the Nobel Prize-winning papers in Physiology or Medicine from Web of Science database and Incites database. For the winning papers that did not reach the expected number of citation, a new index TOPCM was introduced to define them as influential publications with low citation. Most of the Nobel Prize-winning papers were published in high-impact factor journals with long half-life and high citation, and most of the winning papers had high CNCI value. The TOPCM value were mostly high for the winning papers with insufficient citation. There was no significant difference in CNCI value of citing papers between the different citations of the winning papers. Representative papers selection considering source journals should distinguish between top journals and ordinary SCI journals. CNCI values can be used as an important indicator for representative selection. Adding citation indicator of citing papers can effectively supplement the limitation of citation indictor for representative papers selection. Considering the publication cycle and other reasons, the evaluation of representative works should adopt a combination of quantitative and qualitative method.

Spinal cord injury is a serious central nervous system injury, and its repair has become an important topic in the medical field. This study conducts an in-depth analysis of the development trend, main R&D strength, research hotspots and core patents of the field of patent technology, reveals the pattern of patent R&D in this field, and provides support for the research and macro decision-making of my country's spinal cord injury repair technology. The analysis results are: There are 723 patents in the field of spinal cord injury repair around the world, mainly related to the development of spinal cord injury drugs and the use of cells and/or biological materials for injury repair. Since 2001, patents related to cell repair and biomaterials have gradually increased. China and the United States are the main countries in the field of spinal cord injury repair. In the field of drug development and cell repair, the United States has applied for the most patents; in the field of biomaterials, China has applied for the most patents. European and American countries hold most of the core patents, while China holds only one core patent.
