Xi Jinping’s important discussion on adhering to the concept of the system takes “universal connection”, “comprehensive system” and “development and change” as the core categories. It is the creative application and innovative development of dialectical materialistic ontology, epistemology and methodology. Its methodological significance is mainly reflected in: dealing with the present and The long-term relationship between possibility and reality; deal with the relationship between the overall situation and the part, the whole and the part in the overall planning; adhere to the methodological principles such as “collaborative support”, “key breakthrough” and “make up for the shortcomings” in the overall promotion, and deal with the dialectical unified relationship between “two-point theory” and “key theory”. In the new journey of building a modern socialist country in an all-round way, we should adhere to the guidance of Xi Jinping’s important exposition on adhering to the concept of system, give full play to the core role of the Party’s leadership in the overall situation and coordination of all parties, comprehensively promote the construction of a strong country, promote the construction of the “four modernizations” in parallel, and promote the construction of the “five-in-one” as a whole. We should do a good job in major relations such as opportunities and challenges, development and security, efficiency and fairness, domestic and international relations, and provide methodological support for the comprehensive promotion of Chinese-style modernization.
