Abstract:

Objective To analyze the current status and trends of scientific research publications from three-tier Centers for Disease Control and Prevention(CDC) in Shenzhen,providing reference for promoting academic collaborative development within the urban CDC system. Methods Bibliometrics and visualization methods were used to search for journal articles authored by municipal-,district-,and subdistrict-level CDC in Shenzhen from January 2015 to March 2025 in the China National Knowledge Infrastructure, Wanfang,and Web of Science databases. Publication volume,paper quality,core authors,and research hotspots were analyzed. Results A total of 3 651 papers were published by three-tier CDC,with 2 085 as first-author affiliations. The Shenzhen CDC had the highest output as the first-author institution(613 papers,29.4%),district-level institutions averaged 99.0 papers per unit,and subdistrict-level institutions averaged 18.2 papers. Annual Chinese-papers declined overall,while English-papers remained stable. The proportion of papers in internationally indexed core journals and Peking University Core indexed increased,accounting for 41.8% of all publications. Municipal institutions had higher proportions(65.7%) compared to district-level(37.0%) and subdistrict-level(17.2%). Core Chinese-language authors were predominantly from district CDC(80.0%),while English-language core authors concentrated at the municipal CDC(100.0%). Research hotspots exhibited stratification:district and subdistrict institutions focused on disease surveillance and epidemiological practices,while municipal-level research emphasized environmental toxicology and molecular biological mechanisms. Conclusion Shenzhen's CDC system exhibits a hierarchical pattern of "municipal dominance,district potential,and subdistrict weakness" in research output. To foster collaborative innovation,we recommend enhancing grassroots research capacity,strengthening internal and external collaborations,and refining collaboration mechanisms between field departments and laboratories.
