论文摘要
同性恋和异性恐惧症，具有相似特征的人们优先与彼此相互作用（或避免）相似的人的趋势在人类社交网络中普遍存在。在这里，我们开发了城市规模数学理论的扩展，该理论描述了同性恋和异性恐惧症对社会互动的影响以及城市的经济产出。我们模型的经验测试表明，美国城市中的住宅种族异性症和种族隔离的增加与经济产出的减少有关，并且在整个2010年代，这种关系的实力都在增加。我们的发现为将一般同质和恐惧症的正式融合到现代城市科学理论中提供了一种手段，并建议种族隔离越来越多地影响着美国城市社会的经济表现和连通性
Homophily and heterophobia, the tendency for people with similar characteristics to preferentially interact with (or avoid) each other are pervasive in human social networks. Here, we develop an extension of the mathematical theory of urban scaling which describes the effects of homophily and heterophobia on social interactions and resulting economic outputs of cities. Empirical tests of our model show that increased residential racial heterophobia and segregation in U.S. cities are associated with reduced economic outputs and that the strength of this relationship increased throughout the 2010s. Our findings provide the means for the formal incorporation of general homophilic and heterophobic effects into theories of modern urban science and suggest that racial segregation is increasingly and adversely impacting the economic performance and connectivity of urban societies in the U.S.
