The physical structure of cities is the result of self-organization processes in which profit-maximizing developers are key players. The recent Covid-19 pandemic was a natural experiment by means of which it is possible to gain insights into shifts in the spatial structure of cities by studying developers' behavior. Behavioral changes of urbanites triggered by the quarantine and lockdown periods, such as home-based work and online shopping on scales that were unthinkable heretofore, are expected to persist. These are likely to induce changes in the demand for housing, for work, and for retail space, impacting developers' decisions. Associated changes in the land values at different locations are occurring faster than changes of the physical shape of urban landscapes. It is possible that current changes in dwelling preferences will result in significant future shifts in the locational incidence of the urban intensities. We test this hypothesis by examining changes in land values during the last two years by means of a land value model calibrated with vast Geo-referenced data of the major metropolitan area in Israel. Data concerning all real estate transactions include information about the assets and the price of the exchanges. In parallel, built densities are calculated using detailed building data. Based on these data, we estimate the changes of land values for different types of dwellings before and during the pandemic. The result allows us to highlight possible initial signs of post-Covid-19 urban structures, driven by shifting behavior of developers.

城市的物理结构是自组织过程的结果,在这个过程中,追求利润最大化的开发商是关键参与者。最近的新冠疫情是一次自然实验,通过研究开发商的行为,有可能深入了解城市空间结构的变化。隔离和封锁期间引发的城市居民行为变化,比如前所未有的大规模居家工作和网购,预计将持续下去。这些可能会导致对住房、工作场所和零售空间需求的变化,影响开发商的决策。不同地点土地价值的相关变化比城市景观物理形态的变化更快。当前居住偏好的变化有可能导致未来城市强度区位发生率的显著转变。我们通过使用以色列主要大都市区大量地理参考数据校准的土地价值模型,研究过去两年土地价值的变化来检验这一假设。所有房地产交易的数据包括资产信息和交易价格。同时,利用详细的建筑数据计算建筑密度。基于这些数据,我们估计了疫情前和疫情期间不同类型住宅土地价值的变化。结果使我们能够突出由开发商行为转变驱动的新冠疫情后城市结构可能出现的初步迹象。
