一些研究探讨了城市土地扩张（ULE）的驱动因素，但忽略了大区域范围内遥远空间效应对 ULE 的影响。本研究构建了超低能耗空间溢出与交通可达性之间的远程耦合关系框架，以发现距离空间效应对超低能耗的影响。本研究利用1990-2015年土地利用遥感数据和交通网络数据，评估了交通可达性与城市低能耗之间的关系，并建立了二阶空间自回归模型（SO-SAR）来探讨长江经济带城市低能耗的空间溢出机制。结果发现，当可达性连接标准为2h≤hour≤3h时，ULE表现出显着的正空间相关性。 SO-SAR模型结果表明，ULE受到历史ULE的影响，呈现出显着的路径依赖效应。而且，大部分地方城市的ULE对可达性连接标准为1h的周边城市的ULE抑制作用较弱。然而，由于2005-2015年交通可达性的改善，边远城市的城市生活成本的溢出效应对当地的城市生活成本有轻微的正向影响。此外，1990-2015年长江经济带的开放度、劳动力流动、制度层级和经济结构对城市城市生活成本有显着的正向影响。建议进行政策改革，鼓励中国大区域范围内综合交通和城市土地利用的发展。此外，长江经济带城市之间的思维方式需要从城市间的土地竞争转向合作。
Several studies have explored the drivers of urban land expansion (ULE), but disregarded the influence of distant spatial effect on ULE at a large regional scale. This study contributed to a tele-coupling relationship framework between spatial spillover of ULE and transportation accessibility to find the influence of distance spatial effect on ULE. Drawing upon land-use remote sensing data from 1990–2015 and transportation network data, this study assessed the relationship between transportation accessibility and ULE, and developed a second-order spatial autoregressive model (SO-SAR) to explore the spatial spillover mechanism of ULE in the Yangtze River Economic Belt (YREB). The results find that ULE exhibits a significantly positive spatial correlation when the connection criterion of accessibility is 2 h≤hour≤3 h. The SO-SAR model results show that ULE is affected by the historical ULE, which presents a significant path-dependence effect. Moreover, the ULE in most local cities has a weak inhibition on the ULE of the surrounding cities where the connection criterion of accessibility is 1 h. However, the spillover effects of remote city’s ULE have a slight positive impact on local ULE due to the improvement of traffic accessibility from 2005 to 2015. In addition, openness, labor flows, institutional hierarchy, and economic structure had a significantly positive effect on ULE during the period 1990–2015 in the YREB. Policy reforms are suggested to encourage the development of integrated transportation and urban land use at a large regional scale in China. Moreover, there is a need for a mindset shift from cities competing competition over land to cooperation between the cities in YREB.
