Abstract:

Objective To clarify the trend，thematic evolution and international participation structure of cross-border knowledge flow practices in Tianjin City，and explore in depth the optimization path of health governance in Tianjin City. Methods By collecting information on the hosting of international conferences in Tianjin City from various sources and constructing a database，this study employs horizontal，vertical，and structural analyses to delve into the historical development and current status of cross-border knowledge flow in Tianjin City. Results From 2017 to 2024，a total of 86 Tianjin health international conferences were held，increasing from 6 in 2017 to 18 in 2024，showing a steady growth trend in scale. The clinical medicine related conferences accounted for 80%，traditional Chinese medicine accounted for 12%，and public health and preventive medicine accounted for 7%. With the development of traditional Chinese medicine and public health，a cross-border knowledge flow pattern had gradually formed，which was guided by clinical medicine and integrates traditional Chinese medicine，public health，and preventive medicine. The highest number of clinical medicine and traditional Chinese medicine conferences with participation from the United States were 49 and 9，respectively. The number of international public health conferences with South Korean participation was the highest，at 5. The internationalization structure had shifted from being dominated by Europe and America to expanding towards diversification and globalization. Conclusions There is still room for improvement in the international conference brand effect driven high-quality cross-border knowledge exchange，international conference theme structure layout，two-way flow of cross-border knowledge，and achievement transformation in Tianjin's cross-border knowledge flow. In order to promote high-quality cross-border knowledge exchange，efforts can be made to enhance the stability and resilience of international cooperation，optimize the theme structure of international conferences，and improve the precision，long-term effectiveness，and integration of cross-border knowledge exchange mechanisms to promote the improvement of the health governance system and capacity.
