Provided are an ovarian cancer specifically targeted biodegradable amphiphilic polymer, a polymer vesicle prepared thereby and use thereof. The biodegradable amphiphilic polymer is prepared by a polymer containing dithiocarbonate monomer bonded with targeting molecules. The polymer vesicle prepared with the biodegradable amphiphilic polymer can crosslink spontaneously without adding an extra crosslinker, and the crosslink has a reduction activity and hence can be used in drug controlled-release systems, and contributes to the clinical use and production of nano-drugs.
