中文摘要：

采用联立方程分析方法,实证分析了收入不平等对经济增长影响的三种机制,探讨了收入不平等如何通过影响物质资本投资、人力资本投资和居民消费来作用于经济增长。结果表明,从长期看收入不平等的扩大会刺激物质资本投资,但不利于人力资本投资和居民消费增长,收入不平等对经济增长的长期影响为负。因此,从经济发展的角度政府不应容忍收入不平等的过分扩大。

英文摘要：

We use the method of simultaneous equations to study three influence mechanisms of income inequality on economic growth.Our key idea is how income inequality influences on material capital,human capital investment and resident consumption,which impact on economic growth in the end.As a result,the increase of income inequality will stimulate the material capital investment,but restrain the human capital investment and resident consumption in the long run,which indicate that the income inequality negatively influences on the economic growth.Therefore,the government should not allow the bigger income inequality from a view of economic development.
