Abstract:Based on an approach of combining history and theory, this study makes an analysis on the history, theoretical logic and law of the emergence and development of Marxist trade union theory in China. The results of the study demonstrate that the Marxist trade union theory in China is the product of China's social and historical reality, and it is a great achievement of the Sinicization of Marxist trade union theory and the sublimation of the spirit of the times. It is developed in a tortuous way by summing up experience, whereas the key to its development lies in the diligent practice, exploration, thinking and development of Chinese communist party and trade union workers in China. In accordance with the requirements of the new era and tasks, we need further to push forward China's Marxist theory.
