Abstract: The comprehensive and accurate implementation of the concept of shared development in the new journey of Chinese modernization involves the adjustment of interest pattern and interest relationship. It is urgent to explore its interest logic in order to effectively safeguard and promote social public interests, as well as to protect and fulfill the welfare of the populace. However, the imbalance of the current interest pattern seriously hinders the in-depth implementation of the concept of shared development, and there exist interest issues such as uncoordinated interest relations and obvious interest solidification. To this end, we should concentrate on adjusting and balancing different interest relationships, continuously controlling and narrowing the gap between the rich and the poor, precisely balancing the relationship between the government and the market, establishing a new type of labor-capital relationship that is shared and mutually beneficial, and enhancing the interest integration mechanism, so as to realize the sharing of interests and help build a new development pattern.
