Abstract:The 20th National Congress report incorporates the concept of systems thinking into Xi Jinping's ideological framework of socialism with Chinese characteristics for the new era, and utilizes systems thinking to encompass the "Seven Mindsets" (strategic thinking, historical thinking, dialectical thinking, systems thinking, innovative thinking, rule-of-law thinking, and bottom-line thinking). This further clarifies the important position of systems thinking in methodology of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era. Systems thinking is an important component of Marxist dialectical materialism. Marx and Engels, starting from the perspectives of society and nature, established the concepts of "organism" and "collective," regarding nature and society as an interconnected whole. In essence, this treats nature and society as a systemic entity. Marx conducted in-depth research on the complex system of human society, establishing a comprehensive category system that includes concepts such as productive forces, production relations, economic base, and superstructure. He used this category system to profoundly analyze the internal structure and operational mechanisms of the capitalist social system. Throughout the Chinese Communist Party's leadership in the revolutionary, construction, and reform processes in China, successive leadership collectives have consistently adhered to the Marxist systemic perspective, viewing things as organic wholes composed of various elements and their relationships. They have observed, contemplated, and handled various issues in the process of development from a holistic and global perspective. Since the 18th National Congress, the Party Central Committee, with Comrade Xi Jinping at its core, has consciously applied systems thinking to plan the overall work of the Party and the country. It has proposed the principles of upholding and strengthening the Party's overall leadership, promoting the "Four Greats," coordinating the implementation of the "Five-sphere Integrated Plan," and advancing the "Four Comprehensive" strategic layout. They comprehensively grasp the new development stage, implement the new development philosophy, and construct a new development pattern. They have implemented a series of new arrangements and strategies for governing the country, making adherence to systems thinking the fundamental ideological and methodological approach of the Party. Xi Jinping's approach to systems thinking further advances and develops the methodology of dialectical materialism, creatively proposing and applying the methodology of systems thinking.
