Abstract:
 As one of China's strategic emerging industries, the analysis of membrane industrial basic competitiveness can further promote the research and innovation in this field. By using Web of Science's SCI database and DII database, this article takes cocumentary metrology to conduct a comprehensive statistical analysis of 56862 SCI papers and 97,761 patents from the perspectives of annual publication, national distribution, research institutions, and hotspot technologies in the membrane field. Based on the fully understanding of the global membrane development status, this paper has further analyzed the fundamental competitiveness of China's membrane industry research. The results show that: (1) China has taken a leading position in the amount of issued SCI papers and patent applications, and its core competitiveness is distributed in domestic universities; (2) the research hot spots mainly include ion exchange membranes, liquid membranes, and reverse osmosis; (3) although the research foundation in the domestic membrane field has already begun to be competitive, the influence of domestic scientific research institutions and the independent innovation capability of enterprises in the future will still need to be strengthened.
