“Researchers used LDA model to measure policy intensity index based on policy texts from 30 provinces in China from 2013 to 2022, and constructed a spatial weight matrix by modifying the gravity model to represent the multi-dimensional policy network association path. They found that the policy network association of rural industrial revitalization showed a diffusion trend from east to west, and the policy spillover effect was significantly positive but lagged behind, providing empirical evidence for optimizing policies for high-quality industrial development.”
