Abstract: Promoting the deep integration of Party building and professional work in university faculty Party branches is the key to fulfilling the fundamental task of fostering virtue through education and solving the problem of disconnection between primary-level Party building and professional work in the new era. The deep integration of Party building and professional work in university faculty Party branches is essentially the organic combination of Party building and professional work across three dimensions of value, organization, and mechanism, with its internal logic embodied in value alignment, organizational isomorphism, and mechanism synchronization. However, in reality, university faculty Party branches still face deep-seated dilemmas such as cognitive embeddedness failure, structural embeddedness failure, institutional embeddedness failure, and the failure of multi-embeddedness synergy, which constrain the effective release of integration effectiveness. This requires adopting the perspective of organizational embeddedness theory to construct a three-dimensional analytical framework of “value, organization, and mechanism,” systematically explaining the connotation and internal logic of the deep integration of Party building and professional work in university faculty Party branches, and, based on an examination of practical dilemmas, exploring the practical paths for building a “Five-type Synergy” Party branch. The construction of such branches can facilitate the transition of Party building and professional work from physical combination to chemical integration, and achieve a deep integration pattern characterized by value alignment, organizational isomorphism, and mechanism synchronization.
