Abstract: The intention of regional integration policy is to enhance residents' sense of gain by weakening barriers of factor mobility and narrowing regional development gap This paper constructs policy indices from four perspectives： transportation connectivity，weakening of administrative barriers，economic cooperation and labor mobility，and studies the policy effects of regional integration strategy at two aspects： narrowing the income inequality among regional residents and improving their sense of gain It is found that：（1）Regional integration policies can enhance residents' sense of gain based on narrowing the income gap among regional residents，and administrative measures are the main policy measures to enhance residents' sense of gain（2）The convergence of regional income inequality is the objective basis for the improvement of residents' sense of gain，and the policy effects of regional integration policies to reduce regional income inequality are heterogeneous at different stages and in different regions（3）Mechanism analysis shows that the transportation measures and administrative measures in the regional integration policy can significantly narrow the income gap of regional residents by guiding capital to spread to undeveloped areas，which is the major way to enhance residents' sense of gain
