Abstract: ： In this paper, the overall situation of economic development level and poverty incidence in 88 districts and counties of Guizhou province were analyzed by traditional statistical methods and exploratory spatial data. From the combination perspective of global and local space, the coupling interaction between county economic development and poverty were revealed to seek the coordinated development of regional economic development and poverty alleviation from the perspective of spatial coupling effect and provide a dynamic mechanism for the sustainability of precise poverty alleviation. The result showed that the regions with better economic development in Guizhou Province mainly distributed in the central, northern and northwestern regions. The overall distribution of poverty incidence is "U" type situation that low in the north-central, high in the southwest part of Guizhou Province. The poverty reduction rate in some parts of Northern Guizhou and southwest Guizhou presented more rapidly. The degree of coupling and coordination between economic development and poverty incidence showed a downward trend in the study period, and the spatial distribution was significantly different. The low coupling coordination area is mainly located in the districts of Guiyang City and the surrounding counties, which developed well in economic and fully played a radiation driving role and trickle-down effect of the economy. Highly coupled and coordinated areas are mainly located in southeastern Guizhou, which belong to spatial poverty trap area. It suggested that the policies such as relocation and industrial poverty alleviation, etc., should be continuously promoted in Guizhou Province to make up for the poverty-stricken districts and counties.
