Based on constructing a mathematical model to study the integration of agriculture and tourism to alleviate rural poverty,and matching the CFPS micro-database and national leisure agriculture with data of rural tourism demonstration county,this paper calculates the income poverty and multi-dimensional poverty,and further adopts the Probit and Tobit,interaction effect and mediation effect included,to verify the impacts of integration of agriculture and tourism on rural poverty,the regulation of economic development levels and its intrinsic transmission mechanisms from the perspectives of income poverty and multi-dimensional poverty. The results show that the integration of agriculture and tourism can alleviate rural income poverty,but its effect on rural multi-dimensional poverty is not significant; the level of economic development is positively regulating the integration of agriculture and tourism to alleviate rural income poverty,but its regulating effect on the integration of agriculture and tourism to slow rural multi-dimensional poverty is not so obvious; rural residents’ wage level and per capita capital play an important role of transmission mechanisms to mitigate rural income poverty,but an unnoticeable role to mitigate rural multi-dimensional poverty. Therefore, while further developing the integration of agriculture and tourism, “Strategies for special situation” and “multiple measures” can effectively alleviate rural income poverty and multi-dimensional poverty.
