Cultural gravity and redistribution of growth through migration: Cohesion lessons from spatial econometrics and topological data analysis
定义了文化引力作为地方文化环境吸引移民的力量，使用空间回归和拓扑数据分析方法，量化了欧盟28个地区文化引力与经济引力之间的关系，揭示了文化摩擦对增长再分配的影响。
Cultural Gravity is defined as the power of the cultural milieu of a locality to attract immigrants. We test the impact of Cultural Gravity on the spatial clustering and productivity of culturally diverse migrants throughout the European Union . We add to the literature in two ways. First, we clarify the position of the notion of Cultural Gravity within the urban economics literature on moving centres of economic gravity, spatial frictions, and redistribution of growth. Second, we use spatial regression methods, and topological data analysis approaches to quantify the relationship between Cultural Gravity and economic gravity in the EU28 regions. Our findings concord with earlier literature on Cultural Gravity and advance this literature by geographically mapping the invisible and non-linear cultural friction in the redistribution of growth across the EU regions. Thus, we show how Cultural Gravity exerts an important impact on the cohesion process in Europe.
