The Spatiotemporal Non-Stationary Effect of Industrial Agglomeration on Urban Land Use Efficiency: A Case Study of Yangtze River Delta, China

All over the world, Industrial agglomeration has become a key to improve efficiency of urban land use and regulate process urbanization. agglomeration, as universal economic geographical phenomenon, been extensively studied, but few scholars have discussed relationship between industrial efficiency. Based on this, after classifying type externalities, our study uses OLS GTWR models explore complex mechanism interaction externalities efficiency, especially spatiotemporal non-stationary characteristics. We found that impact is significantly unstable in time space, coexistence, substitution aging among different types were also observed. Our research can provide reference for city managers formulate reasonable policies enterprises choose location. Meanwhile, made some contributions academic
