我国居民的收入差距尤其是城乡收入差距，自从改革开放以来在不断扩大，与此同时服务贸易开放度也在不断扩大。利用我国1982—2010年的年度数据，通过引入多个控制变量，采用多元回归模型对不同服务贸易组成部分对我国城乡居民收入差距的影响进行实证检验，结果表明旅游服务、其他商业服务贸易具有缩小我国城乡居民收入差距的效应，而交通运输服务具有扩大我国城乡居民收入差距的效应。今后应进一步通过简化审批、减少垄断来扩大服务业的开放，大力发展服务贸易来抵消部分货物贸易对城乡居民收入差距产生的不利影响。%The residents' income gap of our country constantly expands, especially the income gap between urban and rural areas, since reform and opening up, meanwhile service trade openness is also growing. This paper analyzed empirically the ef-fects of travel service trade and other commercial service trade on residential income disparity in China using annual data of China during 1982-2010 and by introducing several control variables. The results show both tourism service and other busi-ness service trade can narrow income disparities between urban and rural areas, but transportation service has the effect of enlarging our country's urban-rural income disparities. In future, we should enlarge the openness of service industry by sim-plifying examination and approval and reducing monopoly, develop the service trade to offset the harmful effect of partial car-go trade on the urban-rural income disparities.
