The principle of balance of interests refers to “the coordination of conflicting factors in all aspects through the authority of law, so that the interests of relevant parties can achieve a reasonable optimization state on the basis of coexistence and compatibility”

Conflicts of interest can generally be resolved by spontaneous social adjustment. However, with the diversification of interests and the unlimited demand for interests, conflicts of interest have exceeded the scope of spontaneous social adjustment. Accordingly, the law emerged as an effective means to resolve conflicts of interest. The law adjusts conflicting interests, arranges the order and hierarchy of interests, and provides answers to various interest evaluation questions, that is, it provides a series of evaluation norms before people pursue interests. The law resolves conflicts of interest based on stable evaluation norms, making the law a stable and effective conflict-of-interest resolution mechanism that keeps the conflicting parties in a balanced state of interest relationships.
