摘　　要：目前城乡差距过大已经成为我国收入分配领域最主要的问题之一,过大城乡收入差距抑制了农村居民的消费需求,制约了农村居民的人力资本积累,从严重阻碍了产业结构升级,进而对经济持续增长产生了消极影响。但是,城乡收入差距究竟多大才是适度的,在理论上并没有明确的阐释。本文通过一个劳动力迁移的两部门模型,确立了以经济效率为参照标准的城乡收入差距适度水平,对适度水平任何方向的偏离都会导致经济效率的损失。以此为标准,本文还对我国城乡差距的适度水平进行了实证检验,结论显示,我国城乡收入差距已经偏离适度水平,必须进行调整。The excessive urban and rural income difference has become one of the uppermost problems in income distribution field, which has restrained consumption demand and human capital accumulation of ntral resident, thus, impeded China＇s Industry Structure Upgrading, affect sustainable economic growth. However, how many is appropriate about the urban and rural income difference？ It is not denfinite in theory. This paper defined the appropriate level of urban and rural income difference according to economic efficiency, any departure to which will lead to the loss of economic efficiency. According to this standard, this paper proof-tested the appropriate level of urban and rural income difference in China.
