PROBLEM TO BE SOLVED: To obtain a vinyl chloride-based resin capable of providing a molding product suppressing yellowish discoloration in molding and processing by using a complex metal stabilizer such as calcium-zinc mixture, etc., not causing plate out, having slight fish eye resulting from scale, excellent color tone and appearance. SOLUTION: In producing a vinyl chloride-based resin by subjecting a vinyl chloride-based monomer to suspension polymerization in an aqueous medium using a dispersion stabilizer, aβ-diketone compound and a polyalkylene oxide are added to the polymerization system.
