How Densely Do Manufacturing Establishments Occupy Land?
利用加拿大制造业企业的地块和建筑足迹数据，分解工业密度为拥挤度、建筑高度和地块覆盖率，发现大城市和中心位置的企业用地更密集，且大型企业人均用地更少。
Abstract We construct a new dataset containing parcel sizes and building footprints of Canadian manufacturing plants and decompose industrial density (parcel size per worker) into: crowding (floorspace per worker); building height (floorspace to building footprint); and parcel coverage (building footprint to parcel size). We find that establishments occupy parcels more densely in big cities and central locations, and that larger establishments use less land per worker. Floorspace per worker is unrelated to distance from the city centre. The estimated elasticity of substitution between land- and non-land factors is small, between 0.14 and 0.42.
