In the process of Chinese-style modernization，China's economy must get rid of the path dependence of traditional quantitative growth，and strive to promote high-quality development，so as to ease the major social contradictions and achieve sustainable，healthy and stable economic developmentIn the process of Chinesestyle modernization，the systematic logic of promoting high-quality economic development in China includes five dimensions: historical logic，value logic，theoretical logic，practical logic and policy logicStarting from the historical logic of promoting high-quality economic development，the transformation of major contradictions determines that China's economic development model must transform from quantitative economic growth to high-quality developmentThe value logic requires the establishment of a value judgment system with quality as the development goal，and the formation of a value judgment system that combines real value with ultimate valueThe theoretical logic is the optimal path choice for China's high-quality economic development，and the optimal path choice should be the quality coupling and interaction among economic system，natural system and social system that meet the requirements of value logicThe optimal path choice is embodied in the practical logic of the trinity of micro quality，meso quality and macro quality at the micro，meso and macro levelsFinally，the key to the policy logic is to establish a policy system with innovation driven policies，structural coordination policies and quality change policies as the core
