The coupling and coordination of high-quality agricultural development (HQAD) and rural revitalization is an inevitable choice to accelerate the realization of Chinese-style agricultural and rural modernization. Based on system theory, this study reconstructs the indicator systems of both and conducts measurements by applying the improved AHP-entropy weight method. This study has extended the analytical methods of kernel density estimation, Dagum Gini coefficient, sigma convergence, and spatial beta convergence to further investigate the spatio-temporal evolution, regional disparities, and con...
