摘　　要：文章构建理论模型表明交通扶贫具有破解连片特困地区空间贫困陷阱的作用,通过构建基于动态空间杜宾模型(DSDM)的实证模型,以滇桂黔石漠化区为例,运用2003~2016年的有关数据,分析交通扶贫破解空间贫困陷阱的效果及机制。研究结果表明,交通扶贫对滇桂黔石漠化区破解空间贫困陷阱的效果明显。在作用机制上,交通扶贫具有空间外溢效应,服从空间距离衰减规律;交通扶贫兼具短期和长期减贫作用;且与其他减贫因素之间存在交互作用。因此,继续加大交通扶贫力度,科学制定跨区域的交通网络规划,统筹推进交通网络建设,有利于更好地发挥交通扶贫的作用,助力连片特困地区实现脱贫目标。The paper constructs a theoretical model for transport construction in breaking spatial poverty trap.Using the data from 2003 to 2016 and employing the Dynamic Spatial Durbin Model(DSDM),it analyses the effect and mechanism of poverty alleviation through transport construction with the aim to break out of the spatial poverty trap.The contiguous rocky desertification areas in Yunnan,Guangxi and Guizhou are used as examples.The results show that poverty alleviation through transport construction has a main effect on breaking out of spatial poverty traps.It has a spatial spillover effect which follows the rules of spatial distance attenuation.The poverty alleviation through transport construction has both short-term and long-term poverty alleviation effects.And there is interaction effect between transportation poverty alleviation and other poverty alleviation.It is necessary to plan trans-regional transport networks scientifically and to promote transport network construction.
