【摘要】 本文在劳动力异质的假设下通过建立一个二元经济模型分析发展中国家技术进步与收入差距的关系,结果显示技术进步主要通过直接和间接两种途径影响收入差距:其一,通过提高相应劳动力的劳动效率,提高其工资;其二,通过收入差距的扩大,吸引劳动力进行人力资本投资,从而劳动力效率的提高,影响其收入。并得出结论,不同类型的技术进步对收入差距的影响存在较大差异,而这种差异在某种程度上影响人力资本投资,因此,在城乡转化的过程中,要缩小收入差距必须选择适当的技术进步,而且还要结合长期经济发展注意保持相应的收入差别。更多还原

【Abstract】 We set up a dual economic model based on heterogeneous labor assumption to analyze technological progress and income gap in developing countries.We found that technological progress impacts income gap in direct and indirect ways.First,it positively affects income via productivity.Second,it affects income through human capital investment and productivity stemming from increased income gap.Our results show that different kinds of technological progress have different impacts on income gap.The difference may in some extent affect human capital investment.Thus,proper technological progress needs to be adopted to decrease income gap to stimulate long term economic development.更多还原
