Socialist ecological civilization and common prosperity are two important strategies in my country's new journey of comprehensively building a modern socialist country.Both have rich theoretical connotations and action logic.There is a close matching mechanism between the construction of socialist ecological civilization and common prosperity,including:unity of goals and themes,both of which are the proper meaning of Chinese modernization;consistent political logic,and both uphold and improve the party's leadership;specific Path collaboration advocates promoting the modernization of the national governance system and governance capabilities;action subject linkage advocates unleashing the power of the people.Promoting the coordinated progress of socialist ecological civilization and common prosperity requires accelerating the green transformation of development methods,optimizing the distribution pattern in the ecological field,innovating the path to realize the value of ecological products,and promoting mountain-sea collaboration projects.At the same time,we should also realize that there is a certain tension between the relationship between socialist ecological civilization and common prosperity.
