组织工程与再生医学领域科研竞争格局分析OA

Objective To depict the competitive landscape of scientific research in the field of tissue engineering and regenerative medicine through scientific data.Methods Academic papers in this field were retrieved from the Web of Science database,and the number of publications,the number of highly cited papers,and their proportions were compared between different countries globally and different cities within China to assess China's research strength in global competition and the research capabilities of various cities in China.Results From 2015 to 2024,a total of 128127 papers were published globally in the field of tissue engineering and regenerative medicine.From the perspective of global competition,China(41190 papers,433 papers)and the United States(31044 papers,411 papers)led the field in terms of publication volume and highly cited papers.China's compound annual growth rate of publications reached 9.0%,while the United States showed a declining trend.A total of 19 institutions from China,including Shanghai Jiao Tong University,Chinese Academy of Sciences,and Sichuan University,ranked among the top 30 globally in terms of publication volume.From the perspective of domestic competition,Shanghai(6840 papers,98 papers)and Beijing(6610 papers,82 papers)significantly outperformed other cities in terms of both publication volume and highly cited papers.Both cities had multiple institutions and teams that accumulated substantial research achievements.Conclusion China's research scale in the field of tissue engineering and regenerative medicine continues to expand,accumulating a large number of top-tier research results,with many institutions and teams ranking among the global leaders.Beijing and Shanghai demonstrate strong research output as national research hubs,while cities like Guangzhou,Chengdu,Hangzhou,Wuhan,Nanjing,Xi'an,and Shenzhen show notable activity as regional research centers.
