This study uses the journal articles on the theme of “Overseas Chinese” in the CSSCI database from 1999 to 2020 as the data source，and combines with bibliometric methods to analyze the core authors of Overseas Chinese research in China. The results show that the core authors of overseas Chinese research have a relatively balanced gender ratio，and a high education level，but its aging age structure is obvious with its insufficient reserves of young scholars，high impact of their achievements but weak sustainability；the multidisciplinary cross-research team of core authors has not yet been formed for its cooperation network is not close with insufficient collaborative research results，and the dialogue between practical work needs and theoretical research is not sufficient，so the highly collaborative academic community has not been formed between them either with a lack of effective incentives and evaluation. The study concludes that we can start from four aspects to help promote the crossover and integration of related disciplines，cultivate core authors，form a multidimensional subject and cross-regional cooperation exchange network，and improve the sustainable output rate and impact of results by strengthening the training and team building of the reserve force of overseas Chinese research，attaching importance to the disciplinary construction，promoting the academic exchanges and cooperation between overseas Chinese research and the core scholars，and exploring the establishment of a diversified，scientific and reasonable research incentive and evaluation system.
