进入新世纪以来,中国行业收入不平等有持续扩大的趋势。基于回归方程的Shap-ley分解结果表明,人力资本、所有制、资本投资、技术等因素对行业收入差距有显著影响,其中人力资本对行业收入差距的贡献约为45%,所有制的贡献在20%以上。因此在治理措施上,实施教育均等化,提高教育回报率,开放垄断行业的劳动力市场,推行劳资谈判制度可以有效缓解行业收入差距持续扩大的问题。
After entering the new century,the inter-industry wage differentials in China is expanding continually.The regression-based Shapley-value decomposition shows that such factors as human capital,ownership system,capital investment and technology have significant influence on the inter-industry income inequality;of which the contribution of human capital to the differentials is about 45%,and the ownership system is more than 20%.Therefore,such administrative measures as equal education,increasing education returns,opening the labor market of monopoly industry,and carrying out labor negotiation system can effectively settle the problem of inter-industry wage differentials.
