In the report of the 19th National Congress of the Communist Party of China,"high-quality development"has been elevated to a level that defines the essential requirement of Chinese modernization,making it the primary task in building a modern socialist country in all respects.Thus,it can be seen that high-quality development is not merely an economic issue,but a fundamental concern that encompasses all aspects of Chinese modernization.From a perspective of value philosophy,the significance of high-quality development to Chinese modernization lies in its synthesis of the experiences and lessons learned from centuries,especially the past century,of human development.Its aims are to fundamentally address the three contradictions in human practice:the contradiction between human beings and nature,between human themselves,and within individuals,so as to achiev true comprehensive harmony of society.
