交通可达性对当地就业增长的网络效应和空间溢出凸显了交通改善的好处超出了新投资的交通基础设施的区域，这对于更好地了解城市交通的土地利用影响非常重要。之前的研究很大程度上忽略了交通网络的影响和对大都市内部就业增长的溢出效应。在本文中，我们结合交通网络分析和空间计量技术，研究了1996年至2018年北京都市区交通可达性对当地就业增长的影响。我们的研究结果表明，交通网络具有显着的正向效应，并且交通可达性对都市区内就业增长存在空间溢出效应。至于空间溢出，我们认为交通可达性对邻近地区的溢出是正还是负取决于空间规模以及经济活动和交通基础设施的类型。我们的研究结果表明，高速公路在相对较小的空间尺度上产生负溢出，主要针对交通服务需求密集的行业，而轨道交通在较大的空间尺度上对轨道交通周边地区的经济产生正溢出，主要针对高阶服务。
The network effects and spatial spillovers of transport accessibility on local employment growth highlight the benefits of transport improvements that extend beyond the areas with newly invested transport infrastructure, which can be important for a better understanding of the land use effects of urban transport. Previous studies have largely ignored transport network effects and spillovers on intra-metropolitan employment growth. In this paper, we incorporate transport network analysis and spatial econometric techniques to examine the impact of transport accessibility on local employment growth in the Beijing metropolitan area from 1996 to 2018. Our results indicate significant positive transport network effects and the existence of spatial spillovers of transport accessibility on intra-metropolitan employment growth. As for the spatial spillovers, we argue that whether the spillovers of transport accessibility on nearby areas are positive or negative depends on the spatial scale and the types of economic activities and transport infrastructure. Our results show that the spillovers of highways are negative at the relatively small spatial scale and mainly for sectors with intensive demand for transport services, while rail transit imposes positive spillovers on the economy of regions around rail transit at the larger spatial scale and mainly for higher-order services.
