城市增长边界扩展机制研究 ——土地存量模型的应用 韩昊英 赖世刚 摘要：本文基于一个假定的理论框架，来证明如何应用土地存量模型来解决城市用地扩展管理问题。研究 将城市增长边界的扩展视为一个土地存量管理问题，通过考察土地存量管理的保留成本、订购成本和缺损 成本，来比较“时间驱动型”和“事件驱动型”两种城市土地存量管理方式或城市增长边界扩展的控制方式。 前者表现为时间序列上的单个、独立的决策，而后者则表现为时间序列上的多个且相联结的决策。研究通 过一个假定和简化的城市增长边界扩展管理案例，证明事件驱动型管理方式比时间驱动型的管理方式的总 管理成本低，该结果表明，制定多个且相联结的决策比单个、独立的决策的收益更大。 关键词：土地存量管理；时间驱动；事件驱动；城市增长边界 The Mechanism of the Expansion of Urban Growth Boundaries: Application of the Land Inventory Model Haoying Han Shih-Kung Lai (Institution of Land Science and Property Management, Zhejiang University, Hangzhou 310029 Department of Real Estate and Built Environment, National Taipei University, Taipei) Abstract: Based on the theoretical framework, in this article we demonstrate how the land inventory model can be used to help manage urban growth by treating the expansion of the urban growth boundaries (UGBs) as an issue of land inventory control. We compare the time- and event-driven systems of the inventory control problem based on the identification and calculation of the holding costs, order costs, and deficiency costs in the invertory control. The former is considered as making single, independent decisions in time, whereas the latter as making multiple, linked decisions in time. Our numerical example shows that the event-driven system is more effective than the time-driven system in that the former incurs less total cost than the former in the UGBs context. The implication is that making multiple, linked decisions would yield more benefits, such as lowering the total cost, to the planner than making these decisions independently.
