标题：Spatial Diffusion Of Economic Impacts And Development Benefits In Hierarchically Structured Trade Regions: An Empirical Application Of Central Place-Based Input-Output Analysis
摘要：This paper examines the spatial diffusion of economic effects from rural to urban subregions. By employing a spatial variation of the supply-demand-pool nonsurvey I-O modeling technique and central place theory, we can construct an interregional I-O model for a functional economic trade region centered on Salt Lake City, Utah. Rural to urban spillovers are explored with summary measures of interconnectedness. It is found that the diffusion of economic effects from lower- to higher-order subregions depends on the infrastructure development of lower-order subregions and on the infrastructure development of intervening subregions. The modeling framework adds a spatial dimension that can enhance the effectiveness of economic impact assessment and economic development policy formation.
