Value and interest are not only the two essential dimensions for the development of ideology,but also"two wings"for the analysis of the connotation of the leading power of socialist ideology.The guiding force of socialist ideology is a practical force that scientifically expresses and truly practices the pursuit of common human values,which drives special interests towards universal interests.It is a"joint force"formed by the value building power,the value practice power,and the interest promotion power.The socialist ideology,with its inherent scientific nature,authenticity,and people-centeredness,has effectively answered the important question of why socialist ideology has leading power.On this basis,the promotion of the leading power of socialist ideology in the new era should be based on its scientific nature to pursue lofty socialist values;it should take authenticity as its driving force to practically transform socialist value pursuits;and being people centered,it should contribute to the progressive realization of the common interests of mankind.
