Since the establishment of the Chinese Public Administration Society (CPAS) in 1988, Public Administration (PA) research and practice have grown considerably after a gap of more than 30 years. Emerging universities and local research institutes have established specialized departments/centres for PA. This study reports on mainland China's performance in PA research by examining publication size, impact and scientometric indicators, including China's global publication share, growth rate, citation impact and leading journals based on the last 15 years publications data, as retrieved from the Social Science Citation Index (SSCI) database; recognized international collaborators and domestic contributors are also considered. Findings suggest that the quantity and quality of mainland China's PA research has increased steadily, with mainland scholars playing equally as important roles as their international peers. Evidence suggests that mainland China scholars will continue to achieve international publishing success. Finally, opportunities and challenges brought about by internationalization are also discussed.
