摘　　要：In this paper,we present an algebraic construction of the fused model for the ABJM spin chain by gluing two adjacent quantum spaces and two original auxiliary spaces.We prove the integrability of the fused model by demonstrating the validity of the Yang-Baxter equation.Owing to the regularity property of the fused R-matrix,we successfully construct the boost operator for the fused model and obtain the third-order charge accordingly.We also investigate the open spin chain Hamiltonian for the fused model and indicate the general common structures of the boundary terms which are further used to analyze the integrability of the flavored ABJM Hamiltonian.
