Based on the sample data of 31provinces of China from 1995 to 2014, this paper analyzes the relation among trade openness, industrial structure and income gap. The empirical result shows that there is a negative correlation between trade openness and income gap. Industrial structure optimization is the positive factor which expands income gap between urban areas and rural areas. The interaction term of trade openness and industrial structure optimization is the negative factor. Industrial structure optimization is influential to the effect of trade openness on income gap. Education level, unemployment rate and the level of financial development are positive factors which promote urbanrural income gap. The rising foreign direct investment and economic development level may narrow income gap. According to the sample data of eastern, central and western regions, eastern region's openness promotes income gap. The trade openness of central region and western region is helpful to narrow the income gap. There is a negative correlation between industrial structure optimization and income gap in eastern region and central region. And industrial structure optimization in western region expands income gap.
