Abstract: Social organization is an important force for the development of socialism with Chinese characteristics in the new era, an important front for the work of the Party and the masses, and an important field for the construction of the CCP's grassroots organizations. Strengthening CCP building in social organizations is conducive to stimulating the vitality of social organizations and leading them to develop in the right direction. It will help expand the CCP's influence in social organizations, strengthen the CCP's class foundation, expand the CCP's mass base, and consolidate its ruling foundation. The main problems faced by the CCP construction of social organization in the new era are:lack of ideological understanding; insufficient CCP building resources and poor activity sustainability; emphasis on organization setting, light work arrangement; the responsibility subject is not clear enough, and the role is not obvious enough. We must uphold the unity of CCP leadership and social organization autonomy in accordance with the law and grasp the characteristics of the law strictly and solidly; We should adhere to problem orientation and strive to solve problems such as the imperfect organizational system and the incomplete organizational coverage.
