Abstract: The Socialist Core Value System is the essential embodiment of socialist ideology as well as an important mental condition in constructing a harmonious socialist society. The social ecology on which the Socialist Core Value System depends has changed greatly during the social transformation, especially during the process of urbanization in China, while the social problems which are caused by them have posed serious challenge to the Socialist Core Value System. To meet the challenge, in addition to restricting interests by the socialist core value, more attention should be paid to honouring commitments to the people in order to make it accepted and practiced generally by the public.
