Abstract Based on the provincial panel data from 1990 to 2016 in China, this paper explores the relationship among circulation industry agglomeration, regional economic efficiency and urban-rural income gap through Panel Threshold Estimate andSystem Generalized Moment Estimation. The results show that: Firstly, the relationship between circulation industry agglomeration and regional economic efficiency has typical nonlinear characteristics. In the stage of lower level economic development, circulation industry agglomeration inhibits the improvement of regional economic efficiency. Once the level of economic development crosses a certain threshold, circulation industry agglomeration begins to promote regional economic efficiency. Secondly, there is always a significant negative dynamic correlation between circulation industry agglomeration and urban-rural income gap. Thirdly, regional economic efficiency helps to narrow the urban-rural income gap, and has mediating effect in the process that the circulation industry agglomeration influences the urban-rural income gap.
