The Chinese style modernization road is not a simple learning and imitation of the modernization road of the West and the Soviet Union. Therefore, the formation of Chinese modernization theory has its unique theoretical logic and practical logic. From the perspective of theoretical logic, the theoretical exploration of Chinese modernization originated from the modernization thoughts of Marxism and Leninism. After the arduous exploration of several generations of Chinese Communist party, a relatively mature theoretical system of Chinese modernization has been formed. From the perspective of practical logic, the practical process of Chinese style modernization can be divided into four stages, in which the practical laws from "passive" to "active" and from "series" to "parallel" appear. An in-depth interpretation of the historical logic, theoretical logic and practical logic of Chinese modernization will help us more comprehensively grasp the connotation, essence, principles and significance of Chinese modernization.
