A statistical analysis of the number of Chinese journals, the amount of literature and the types of articles included in the “Chemical Abstracts” (CA) in the United States was made and compared with that of developed countries. The data show that since the implementation of China’s reform and opening up policy, the number of scientific journals and their number of journals cited by the CA have rapidly increased. The number of journals entering the CA 1000 list has also increased at the same time. The number of English-language periodicals has increased steadily, especially in CA’s Among the top 500 journals, the journals in our country have obviously increased their possession, but there are still some limitations on the number and types of journals.
