Economic Interdependence Within the Chicago Metropolitan Area: A Miyazawa Analysis
运用宫泽扩展投入产出框架，将芝加哥大都市区分为四个区域，分析内城社区与郊区之间的收入形成和产出生成的相互依存关系，发现通勤带来的收入流动比贸易乘数更重要，且相互依存强度不对称。
The present study explores the nature and strength of economic interdependence between inner‐city communities and suburbs within the Chicago metropolitan area. Employing Miyazawa's extended input‐output framework, a multiregional model is used to investigate the interdependence of income formation and output generation. The metropolitan area is divided into four regions and particular attention is directed to predominantly minority areas on the south and west sides of the city of Chicago. The region‐to‐region impacts of trade flows and their associated multipliers proved to be far less important in determining the strength of interregional interdependence in contrast to income flows derived from journey‐to‐work movements. The interrelational income multiplier revealed considerable interdependence between regions although the strength of this interdependence was asymmetric.
