A polyvinyl chloride resin composition contains: from 0.005 to 5 parts by weight of a vinyl alcohol-based polymer containing from 0.01 to 15 mol % of a monomer unit having a specific polyoxyalkylene group in a side chain and having a degree of saponification of from 30 to 99.9 mol %; and from 0.01 to 5 parts by weight of a zinc compound, based on 100 parts by weight of a polyvinyl chloride resin. In addition, a polyvinyl chloride resin composition contains: from 0.005 to 5 parts by weight of a vinyl alcohol-based polymer containing from 0.5 to 18 mol % of an ethylene unit and having a degree of saponification of a vinyl acetate unit of from 30 to 99.9 mol %; and from 0.01 to 5 parts by weight of a zinc compound, based on 100 parts by weight of a polyvinyl chloride resin. A polyvinyl chloride resin composition is thereby provided which is excellent in thermal stability while being shaped and with which a less colored shaped article can be obtained.
