Traffic superiority is an important support for regional economic development. By observing the spatial distribution characteristics of the coupling coordination between regional traffic superiority and economic development, the imbalance and insufficient contradiction between regional traffic and economic development can be revealed, thus providing scientific basis for regional traffic planning and construction. By collecting the relevant indicators of traffic and economic development in 183 districts and counties in Sichuan Province is collected, and calculating the coupling coordination degree of county traffic superiority and economic development level is calculate. It can be observed that the coupling coordination degree of traffic and economy in Sichuan counties shows the spatial distribution characteristics of gradually weakening to the periphery with Chengdu Plain Economic Zone as the core and being high in the east and low in the west.
