Development of life science and basic medicine in China from π index——eight-year π-index analysis report(2016-2023)
Based on π-index algorithm and logistic regression(gradient descent method)algorithm,this study takes nearly 400 000 research papers from 122 journals in 8 years as the research object,and explores the development trends of different countries and institutions in the field of life science and basic medicine around the world and analyze the development of life science and basic medicine in China.Through analysis,it is found that the number of papers published and π factor in the United States have always been the highest in the world,and the growth in China is particularly prominent.Since 2018,the number of papers published and π factor have increased rapidly,ranking first in the world.Judging from the eight-year π-index classification of global TOP500 institutions,the number of sustained and rapid growth institutions in China accounts for the leading position in the world,among which Chinese Academy of Sciences leads the sustained and rapid growth institutions,and the subordinate institutions of Chinese Academy of Sciences also grow rapidly in fluctuations;TOP 100 institutions in China are mainly distributed in the Yangtze River Delta,Beijing-Tianjin-Hebei,Guangdong-Hong Kong-Macao three urban agglomerations,and their annual publication volume and π factor all show a rapid growth trend;The Yangtze River Delta urban agglomeration has the largest number of institutions with sustained and rapid growth,ranking first in the total number of papers published in eight consecutive years.Beijing-Tianjin-Hebei ranks first in China for eight consecutive years,and Peking University,Tsinghua University,Fudan University,Shanghai Jiaotong University,Sun Yat-sen University,Zhejiang University,Peking Union Medical College of China Academy of Medical Sciences and other institutions have sustained and rapid growth.In the past eight years,China's life sciences and basic medicine have grown rapidly.Driven by"talent return"and"capital investment",China's scientific and technological innovation and development in the fields of life sciences and basic medicine have entered the fast lane.
