Objective/Meaning Promoting the effective connection between poverty alleviation and rural revitalization is the top priority of the current “three rural work” in our country. Through the empirical analysis of the coupling coordination relationship between poverty alleviation and rural revitalization in the old revolutionary base areas of Sichuan and Shaanxi, it was expected to provide ideas for the overall promotion of the connection between poverty alleviation and rural revitalization in the old revolutionary base areas.

Methods/Procedures Based on the micro-survey data of the registered households in the Sichuan-Shaanxi old revolutionary base areas in 2021, the index system of coupling coordination evaluation of poverty alleviation and rural revitalization was scientifically constructed. Through the entropy weight method, the coupling coordination degree model and the obstacle factor diagnosis model, the development status, convergence status and main obstacle factors of poverty alleviation and rural revitalization in the old revolutionary base areas of Sichuan and Shaanxi were evaluated and analyzed.

Results/Conclusions The results showed that: (1) On the whole, the coupling coordination degree of the two systems was 0.617, which was at the primary coordination level. (2) From the perspective of villages and towns, the coupling coordination degree of 10 villages and towns was 0.279-0.963, and all of them belonged to the lagging type of rural revitalization. (3) The four indexes of rural civilization, economic development ability, industrial prosperity and wealthy life were the main criterion-layer indexes that restricted the coupling and coordination of the two systems. The intensity of family members’ consumption expenditure on education, culture and entertainment, the education level of family members, the per capita net income level of family members and the help level of poverty alleviation microfinance to increase the family income were the main indicators that restricted the coupling and coordination of the two systems.
