During 2016，the output growth rate of secondary industry keeps decreasing，which leads to the decrease of national economic growth rate and the adjustment of industrial structural change. As a result，both residents’ income and employment affect the structure of income inequality. First of all，the decreasing rate of economic growth will downgrade the wage increase rate among low skilled labor force and reduce related employment opportunities. And both urban residents with lower middle income and rural residents with upper middle income are concentrated in low-skilled labor market. Therefore，the decrease of economic growth rate will widen the income inequality among urban residents. At the same time，this trend will continue the trend of narrowing rural residents’ income inequality since 2015. However，the decreasing economic growth rate may have more negative impact on rural residents’ average income growth rate than urban residents’ income growth rate，which may cause the widening gap of income inequality between urban and rural residents. Therefore，for 2016，the income inequality between urban and rural residents and among urban residents will follow different path，which will cause a widening gap of the income inequality in China.
