Abstract: Based on the panel data from 55 cities in the Yellow River Basin from 2012 to 2021, the coupling coordination degree model, exploratory spatio-temporal data analysis (ESTDA) method, and obstacle degree model were used to reveal the spatio-temporal evolution patterns of the coordinated development between new quality productivity and rural revitalization in the Yellow River Basin. The results showed that, ① in terms of timing changes, from 2012 to 2021, the average coupling coordination degree index between new quality productivity and rural revitalization in the study area ranged from 0.4 to 0.6, indicating a moderate coordination level, with a yearly increasing trend. In terms of spatial distribution, the coupling coordination level increased from the upstream to the midstream and downstream areas of the basin. Most cities showed a yearly increase in the coupling coordination level, but significant differences existed among cities. ②Spatio-temporal dynamic analysis indicated that the spatial pattern of the coupling coordination degree between new quality productivity and rural revitalization in the Yellow River Basin remained relatively stable during the study period. However, the integration of spatial pattern evolution was weak, and the synergistic development effect among regions was not obvious. The spatio-temporal transition matrix indicated that the spatio-temporal mobility probability of the coupling coordination degree was low during the study period, with inertia in the coordinated development levels, resulting in a relatively fixed local collaboration pattern among cities in the short term. ③Obstacle factor analysis revealed that during the study period, technological innovation capability, rural economic income, and rural greening issues gradually became factors restricting the development of the two subsystems of new quality productivity and rural revitalization in the Yellow River Basin. Therefore, measures needed to be taken to address regional development shortcomings to achieve coordinated and sustainable development of new quality productivity and rural revitalization in the Yellow River Basin.
