Abstract: 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.
