Abstract: The development of positivism historiography in China is different from that in western countries. In western countries, positivism historiography is based on the development of science. It not only inherited the historicity of objectivism, but also focused on exploring the rules of history development, opening a new field for study of history. The spreading of Positivism Historiography met the needs of social reform in China. Yan Fu and Liang Qichao cared about how to solve the problems using evolution opinion and positive method.
