摘要

跳跃式开发是指远处的地块被开发,而较近的可开发土地仍闲置的现象。这是一个城市治理问题,因为在现有服务区域未被充分利用之前,基础设施和服务义务就可能向外延伸。本研究扩展了一个交易稀少的土地市场的基于代理的模型(Agent-Based Model),其中买家根据预期 nearby 开放空间能持续多久来对其进行估值。模拟结果显示,仅凭对开放空间的偏好会形成尖锐的城市边缘,而对预期持续性的分级估值则会产生渐进的城市-农村梯度;宣布的分阶段计划也能产生这种梯度,但这取决于具体设置。距离递增的开发费和异质性农业租金则不能产生这种梯度。堪萨斯州塞奇威克县(Sedgwick County)2015–2023年的地块面板数据显示,已开发比例呈逐渐下降趋势,从威奇托市中心三英里内的约95%下降到十三英里外的低于10%。这一模式与预期情景一致,与尖锐边缘情景不一致,尽管其范围比任何模拟情景都要宽。政策实验表明,强制执行的分阶段开发能带来紧凑的发展,但会以住房供应为代价;而仅宣布但不强制执行的分阶段开发则会加剧分散。对于地方政府而言,可信度而非仅仅是宣布,似乎是关键的杠杆。

It is an urban-governance problem because infrastructure and service obligations can be extended outward before existing service areas are fully used. We extend an agent-based model of a thinly traded land market so that buyers value nearby open space by how long they expect it to persist. In the simulations, open-space preference alone leaves a sharp urban edge, whereas a graded valuation of expected persistence produces a gradual urban-rural gradient; an announced phasing schedule can also produce it, depending on settings. Distance-rising development fees and heterogeneous agricultural rent do not. A 2015–2023 parcel panel for Sedgwick County, Kansas, shows a gradual decline in developed share, from about 95% within three miles of downtown Wichita to below 10% beyond thirteen miles. The pattern is consistent with the expectation scenarios and inconsistent with the sharp-edge scenarios, although wider than any simulated scenario. Policy experiments suggest that enforced phasing yields compact development, at some cost in housing supply, whereas phasing that is announced but not enforced spreads it. For local governments, credibility, not announcement, appears to be the lever.

结论

对于地方政府而言,在控制跳跃式开发和促进紧凑发展方面,政策的可信度(即强制执行)比仅仅宣布计划更为关键,尽管这可能会以牺牲一定的住房供应为代价。
