Based on panel data from 11 provinces and cities in the Yangtze River Economic Belt from 2016 to 2021, this article constructs a coupling coordination indicator system for rural basic public services and economic development, and uses entropy method and coupling coordination degree model to study the coordination characteristics between rural basic public services and economic development in the Yangtze River Economic Belt. The research shows that: The basic public service system and economic system development indexes in rural areas of the Yangtze River Economic Belt are both showing an upward trend, and the development trend is good; The level of coordinated development between the two systems has been increasing year by year, but the spatial development is uneven, showing an overall spatial difference pattern of "downstream>midstream>upstream"; The coupling and coordinated dispatch of the Chengdu-Chongqing urban agglomeration and the Yangtze River Delta urban agglomeration tends to develop synergistically, and the differences between the three major regions are narrowing down; The overall coordination level of the Yangtze River Economic Belt is improving. Accordingly, Suggestions are proposed from three aspects: strengthening policy guidance and financial support, formulating differentiated development policies, and optimizing the spatial pattern of basic public services.
