IF ALONSO WAS RIGHT: MODELING ACCESSIBILITY AND EXPLAINING THE RESIDENTIAL LAND GRADIENT
研究发现，就业可达性是城市土地价格的重要决定因素，重力模型可达性指标能完全解释住宅用地梯度，并分离出可达性的正效应和交通拥堵的负效应。
ABSTRACT This study provides an empirical evaluation of employment accessibility as a determinant of urban land price. We find that the monocentric model, despite recent criticism, can perform satisfyingly if the hedonic value of land is identified in an account of structural and neighborhood characteristics. Gravity employment accessibility measures, however, can explain the residential land gradient entirely and disentangle positive accessibility effects from negative congestion effects related to transport infrastructure. They can therefore be recommended as an appropriate mean to account for labor market accessibility in an environment of dispersed employment, at least if the transport geography is accounted for.
