论文摘要
大都市地区的城市动态是由社会，经济和政治因素之间的复杂互动造成的，包括人口分配，财富流和基础设施要求。我们在2011年和2016年为大悉尼和墨尔本地区开发了人口普查城市动态模型，强调了人口分布的演变以及这两个城市的抵押和租金分配中的住房市场结构。我们表明，租房者和抵押持有人之间存在同质的趋势：租房者倾向于将其聚集在更接近商业中心，而抵押人则倾向于居住这些中心的郊区。我们还确定了一个临界阈值，即这两个城市的长期演变将在“散布”和“多中心”配置之间分叉，这表明两个城市都位于长期临界点的多中心侧。重要的是，租房者和抵押贷款持有人之间的这些以中心倾向存在分歧。表征抵押机的多中心模式集中在商业中心周围，我们表明，新兴的住房模式沿着城市的主要运输路线沿着城市的主要运输路线沿用。
Urban dynamics in large metropolitan areas result from complex interactions across social, economic, and political factors, including population distribution, flows of wealth, and infrastructure requirements. We develop a Census-calibrated model of urban dynamics for the Greater Sydney and Melbourne areas for 2011 and 2016, highlighting the evolution of population distributions and the housing market structure in these two cities in terms of their mortgage and rent distributions. We show that there is a tendency to homophily between renters and mortgage holders: renters tend to cluster nearer commercial centres, whereas mortgagors tend to populate the outskirts of these centres. We also identify a critical threshold at which the long-term evolution of these two cities will bifurcate between a `sprawling' and a `polycentric' configuration, showing that both cities lie on the polycentric side of the critical point in the long-run. Importantly, there is a divergence of these centric tendencies between the renters and mortgage holders. The polycentric patterns characterising the mortgagors are focused around commercial centres, and we show that the emergent housing patterns follow the major transport routes through the cities.
