[Methods] Using data from Chinese core scientific journals, statistical analysis was conducted on the overall inclusion status, citation and source indicators, disciplines, regions, the number of articles, and basic information of the journals. [Findings] From 2020 to 2022, the main indicators such as the core total citations, core impact factors, and the ratio of funded papers in journals have been increasing year by year. Beijing, Shanghai, Jiangsu, Hubei, and Shaanxi have the largest number of core journals. In 2022, 456715 papers are published in core journals in the field of natural sciences and 50025 in the field of social sciences. China's core scientific journals (including natural science and social science fields) are mainly established during 1978-2000, with the largest number of bimonthly periodicals. In natural science field, bimonthly periodicals account for 45.0%. In the social science field, bimonthly periodicals account for 55.8%.
