The invention relates to the technical field of chemical material preparation, in particular to a carbon dioxide selective absorption core-shell structure polyamide microsphere and a production device thereof, the structure of the carbon dioxide selective absorption core-shell structure polyamide microsphere is as follows: [Cu2 (L) (H2O) 2]. [NH-R-CO-R-CO] x is taken as a core, polyamide is taken as a shell, X-ray single crystal diffraction data analysis reveals that the space group of the microsphere is I4/m, two copper ions are linked through four isophthalic acids to form a plane square wheel paddle-shaped SBUs, the bond length of Cu-Cu is about 0.2646 nm, the bond length of Cu-O is 0.196-0.198, 12 SBUs are connected together through 24 isophthalic acids, a small rhombic hexahedron MOP is formed, the nanosphere is a core, the outer layer is coated with a polyamide shell, the device comprises a reaction box, a clamping table is fixed at the bottom in the reaction box, and the clamping table is fixed at the
