摘　　要：为系统探讨区域协同发展对城市蔓延的影响,本文首先构建了区域协同发展影响城市蔓延的理论框架;其后,采用固定效应模型、门槛效应模型、空间计量模型和空间门槛模型揭示区域协同发展对城市蔓延的影响效应、非线性作用机制以及不同阶段区域协同发展对城市蔓延的空间门槛效应、空间溢出边界.结果表明:1)区域协同发展对城市蔓延具有抑制效应.在此基础上,门槛效应表明两者关系存在“先促进、后抑制、再抑制效应加强”的非线性特征且受到人口流动、产业发展、环境关注以及交通建设的门槛约束.2)本地区域协同发展水平提升会加剧邻近地区的城市蔓延,具有明显的“以邻为壑”特征,但空间效应的衰减边界仅为280千米.3)随着区域协同发展水平的提升,其对本地城市蔓延的抑制作用将不断提高,而对周边地区城市蔓延的促进作用将不断减少.4)在区域协同发展的不同阶段,其对城市蔓延的空间溢出效应均表现出波浪型的空间距离衰减特征,且辐射边界随着区域协同发展水平的增加而收缩.To systematically explore the impact of regional synergistic development on urban sprawl,this paper firstly constructs a theoretical framework of regional synergistic development on urban sprawl;Subsequently,the fixed effects model,threshold effects model,spatial measurement model and spatial threshold model were used to reveal the effects and non-linear mechanisms of regional synergistic development on urban sprawl,as well as the spatial threshold effects and spatial spillover boundaries of regional synergistic development on urban sprawl at different stages.The results show that:1)Regional synergistic development has an inhibitory effect on urban sprawl.On this basis,the threshold effect indicates that the relationship between the two has a non-linear characteristic of“first promoting,then inhibiting,and then strengthening the inhibitory effect”,and is constrained by the thresholds of population mobility,industrial development,environmental concerns and transportation construction.2)The increase in the level of regional synergistic development of the local region will exacerbate the phenomenon of urban sprawl in the neighboring regions,which has the obvious characteristic of“beggar-thy-neighbor”,but the boundary of the spatial effect of the attenuation is only 280 km.3)As the level of regional synergistic development increases,its inhibitory effect on local urban sprawl will continue to increase,while its facilitating effect on urban sprawl in neighboring areas will continue to decrease.4)The spatial spillover effect of regional synergistic development on urban sprawl at different stages shows a wavy spatial distance decay characteristic,and the radiation boundary shrinks as the level of regional synergistic development increases.
