The invention relates to an early-strength polycarboxylate water reducing agent. The early-strength polycarboxylate water reducing agent is prepared from a monomer A, a monomer B, a monomer C and a monomer D, wherein the molar ratio is 20-30 to 80-90 to 4-6 to 3-5. Under the effect of an initiator and a chain transfer agent, all the monomers are copolymerized into a polymer with the molecular weight ranging from 80,000 to 1,000,000. The early-strength polycarboxylate water reducing agent is high in water reducing rate, the early strength of concrete can be greatly improved, and the production requirement for the early strength of a prefabricated part can be met.
