The invention discloses a method for synthesising a diblock copolymer by simultaneous chemoenzymatic process and one-pot process, and belongs to the technical field of synthesis and preparation for a high-molecular material. Enzymatic polymerization and atom transfer radical polymerization are fused in a reaction system, and two polymerization reactions with different polymerization mechanisms are simultaneously initiated to be simultaneously performed by the different functional groups of a bifunctional initiator in the conventional reaction conditions. With the adoption of the method disclosed by the invention, the cockamamie processes of multi-kettle polymerization and single-kettle multi-step polymerization are avoided, separation and purification for an intermediate compound needed in the multi-step operations are avoided, the pollution brought by a solvent is reduced, the supercritical CO2 reaction condition used in a chemoenzymatic and one-pot polymerization technology is avoided, and the cockamamie sy
