The Economic Health of Municipalities within a Metropolitan Region: The Case of Chicago
构建因果模型分析1980年芝加哥大都市区184个市镇的就业与失业变化对经济健康的影响，通过路径系数排名并识别空间自相关，发现衰退市镇的空间聚集性更强。
A causal model is developed that links the effects changes in employment and unemployment have on response variables that represent the economic health of 184 municipalities in the Chicago SMSA for 1980. Two causal series of paths are particularly helpful in identifying economic health. One represents the current level of health; the other, more relevant, path represents the trend during the period 1970-1980. By use of an index based on the path coefficients the municipalities are ranked with regard to level and trend. A second-order type of analysis is employed to identify spatial autocorrelation among the communities with regard to the two series. Results indicate that declining communities with regard to the two series. Results indicate that declining communities are more strongly associated spatially than are communities that are in relatively good economic health.
