It is found that the development trajectory of the interdisciplinary research on big data and public administration has a strong response to national policies. The research further uses the Boston matrix to analyze the theme layout of this interdisciplinary research projects from four dimensions, namely, the introduction period, the growth period, the maturity period and the reduction period. The results show that medical and health management, public security and emergency management, public opinion management and other themes are in the mature and growth period of this interdisciplinary research field, moreover, they are the research hotspots of this interdisciplinary research field. Meanwhile, some strong research teams have completed the transition from pioneering to agglomeration and made distinctive and influential research achievements in this interdisciplinary research field. Based on this, suggestions are put forward to promote the continuous deepening and transformation and upgrading of interdisciplinary research on big data and public administration.
