Hotspot mining of public health science and technology policies and identification and analysis of frontier themes in fund projects
Objective From the perspective of policy and fund projects,this paper explors and excavates policy hotspots and cutting-edge topics in the field of public health science research.Understand the distribution of fund project themes under different policy orientations,sort out key research areas of public health,and provide empirical basis and scientific reference for relevant management and decision-making departments.Methods Using the BTM topic word model,combined with indicators such as topic intensity and topic novelty,theme analysis and text mining were conducted on the text data of science and technology policies in the field of public health and National Natural Science Foundation projects from 1990 to 2019.Results A total of 8 policy themes in the field of public health were excavated,among which the most popular policy themes include"Environmental factors and public health and safety guarantee"and"Grassroots health services".A total of 26 research topics from public health fund projects were identified,including 6 cutting-edge hot topics,with the highest intensity being"susceptibility to chronic disease genes".There is a distribution of research topics for funding projects in various public health science and technology policy themes.Except for the policy theme of"Biological Foundations of Human Health and Diseases",other policy themes have a distribution of cutting-edge topics of funding project hotspots.The number of fund projects related to research directions in the policy theme of"grassroots health services"is relatively small.Conclusions The goal orientation of public health policy science and technology themes is reflected in fund projects,with the key being demand driven,breaking through bottlenecks.The condensed scientific questions stem from social needs.From the perspective of fund project management,we must adhere to the two legged approach of public health science and technology policy goal orientation and scientific freedom exploration,strengthen the deployment of disciplinary systems,enhance original innovation capabilities,and serve national needs.
