Disclosed is a catalyst composition for polyurethane resin production which contains (A) triethylenediamine, (B) a specific polyisocyanurating catalyst and/or (C) a specific highly temperature-sensitive catalyst. By using this catalyst composition, a polyurethane resin can be molded with good curability, while suppressing initial reactivity. Consequently, a polyurethane resin having excellent moldability and fluidity can be produced with high productivity by using the catalyst composition. The thus-obtained polyurethane resin is suitably applicable to shoe soles. The component (B) is selected from the group consisting of alkali metal salts of carboxylic acids, quaternary ammonium compounds expressed as R

, N,N,N′-trimethylaminoethylethanolamine, and 2,4,6-tris(dimethylaminomethyl)phenol, while the component (C) is selected from the group consisting of triazole salts and benzotriazole salts of 1,8-diazabicyclo[5.4.0]undecene-7 or 1,5-diazabicyclo[4.3.0]nonene-5. The mixing ratio of the component (B) and/or the component (C) to the component (A) is from 2% by weight to 60% by weight.
