目的 识别我国在生物医学工程领域国际合作参与度较高的城市和机构,并发现我国在该领域的国际合作特点.方法 在Web of Science数据库中检索生物医学工程主题的论文,使用Excel和Pajek软件对我国城市和机构的国际合作论文发文情况进行描述性统计分析和合作网络的变化趋势分析,并采用逼近理想解排序法(Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS)综合评价城市和机构在合作网络中的重要性.结果 共检索获得生物医学工程相关论文45944篇,经描述性统计发现,北京、上海、广州和深圳的国际合作发文量处于全国前列,香港、西安和温州的国际合作发文比例较高;通过量化国际合作水平发现,以上城市在国际合作中的积极性、合作网络中的重要性及TOPSIS得分均处于较高水平.从机构层面来看,北京、上海和广东的一些高校国际合作较为积极.结论 本研究通过量化生物医学工程领域研究论文的国际合作网络,识别了国内国际合作方面最为积极和重要的城市与机构,了解了目前该学科国际合作下较为热门的研究方向,并为提升我国生物医学工程领域的国际合作程度提出建议.
Quantitative Measurement of International Collaboration Participation for Chinese Cities in the Field of Biomedical Engineering
Objective To identify Chinese cities and institutions with high participation in international cooperation in the field of biomedical engineering,and to discover the characteristics of China's international cooperation in this field.Methods Papers on the topic of biomedical engineering was searched from the Web of Science database.Excel and Pajek software were used to make a descriptive statistical analysis of the international cooperation papers issued by Chinese cities and institutions,and the change trend of cooperation networks was analyzed.The technique for order preference by similarity to an ideal solution(TOPSIS)was used to evaluate the importance of cities and institutions in the cooperative network.Results A total of 45944 papers related to biomedical engineering were retrieved.Descriptive statistics showed that Beijing,Shanghai,Guangzhou and Shenzhen rowed in the forefront of China in the number of international cooperation publications.Hong Kong,Xi'an and Wenzhou had a higher proportion of international cooperation papers.By quantifying the level of international cooperation,it was found that the enthusiasm of the above cities in international cooperation,the importance of cooperation network and TOPSIS scores were at a high level.At the institutional level,some universities in Beijing,Shanghai and Guangdong were more active in international cooperation.Conclusion By quantifying the international cooperation network of research papers in the field of biomedical engineering,this study identified the most active and important cities and institutions in domestic and international cooperation,understood the current popular research directions in the field of international cooperation,and put forward suggestions for promoting the degree of international cooperation in the field of biomedical engineering in China.
