The present invention discloses a synthesis method for a hyperbranched biodegradable polyester plasticizer, comprising the following steps: filling a reaction vessel with nitrogen to expel oxygen from the air, mixing a lactic acid monomer, a polyol or polyol acid and a catalyst, and heating in a negative pressure environment, so that condensation polymerization reaction is carried out between the lactic acid and the polyol or polyol acid in the reaction vessel, to prepare a hyperbranched oligomeric polylactic acid, namely, the hyperbranched biodegradable polyester plasticizer. According to the method of the present invention, a polyol or polyol acid is used as a core molecule, and a hyperbranched polylactic acid generated by means of polymerization has higher plasticizing efficiency than traditional straight-chain polyester plasticizers due to the fact that the multi-arm structure of the hyperbranched polylactic acid can effectively increase the distance between PVC molecular chains when PVC is plasticized, and has excellent transference resistance and volatility resistance due to the fact that the molecular weight of the hyperbranched polylactic acid is higher than that of traditional orthophthalic plasticizers.
