人力资本投资、收入差距与养老金制度改革

Human Capital Investment,Income Gap and Pension Institution Reform

笔者利用封闭经济下的二期OLG模型,考察了在人力资本投资和资本—技术互补条件下,中国养老金制度改革后对收入差距的影响。理论模型表明,基金制份额的提高增加了物质资本和人力资本,拉大了中国的收入差距;实证亦证实了混合制是拉大中国收入差距的单向格兰杰原因。

Using a two-period OLG model in closed economy, the aothor reviews the influence of pension institution reform in China on income gap under the conditions of human capital investment and capital-skill complementarity. The theoretical model shows that the increase in funding share has increased material capital and human capital, and widened income gap in China. The empirical test also proves that the mixed pension institution is the one-way Granger cause of widening income gap in China.
