Abstract

Most studies have explored the association between transportation and urban–rural disparity. However, research focusing on the impact of transportation accessibility on these issues has been relatively scarce. This paper contributes to the literature by examining the spatially varying impacts of multiscale accessibility on urban–rural income disparity (URID) in the Qinba mountainous region (QBM) of China. The results further highlight the differing impacts of county-level, prefecture-level, and provincial-level accessibility on URID. The MGWR model confirms that the effects of multiscale accessibility on URID are spatially heterogeneous. Specifically, county-level accessibility has a significantly negative effect on URID. In contrast, the impacts of prefecture-level and provincial-level accessibility are significantly positive in narrowing the URID, leading to a “diffusion effect.” The narrowing effect of prefecture-level and provincial-level accessibility on URID is more pronounced in the eastern and northern parts of QBM, respectively. In the western mountainous areas of QBM, where most counties experience relatively low accessibility and high URID, prioritizing the expansion of connectivity between mountainous and well-developed areas, optimizing the layouts of villages and towns, and improving overall accessibility is essential. The findings suggest that the implementation of accessibility improvements and transport plans should be place-specific, considering the geographical and socio-economic contexts.

中国山区可达性对城乡差异的异质性影响

大多数研究都探讨了交通与城乡差距之间的关系。然而，关于交通可达性对这些问题影响的研究相对较少。本文通过研究秦巴山区多尺度可达性对城乡收入差距的空间差异影响，为文献贡献一份力量。研究结果进一步凸显了县级、地级市和省级可达性对城市资源开发的不同影响。MGWR模型证实了多尺度可达性对城市空间特征的影响具有空间异质性。具体而言，县级可达性对城市资源开发具有显著的负向影响。而地级和省级可达性对城市可达性的影响均显著为正，呈现“扩散效应”。地级可达性和省级可达性对城市发展水平的缩小效应分别在东部和北部地区更为明显。在QBM西部山区，大部分县域通达性相对较低，城市化程度较高，应优先扩大山区与发达地区的连通性，优化乡镇布局，提高整体通达性。研究结果表明，考虑到地理和社会经济背景，可达性改善和运输计划的实施应因地制宜。

期刊介绍： Description The journal has an applied focus: it actively promotes the importance of geographical research in real world settings It is policy-relevant: it seeks both a readership and contributions from practitioners as well as academics The substantive foundation is spatial analysis: the use of quantitative techniques to identify patterns and processes within geographic environments The combination of these points, which are fully reflected in the naming of the journal, establishes a unique position in the marketplace. RationaleA geographical perspective has always been crucial to the understanding of the social and physical organisation of the world around us. The techniques of spatial analysis provide a powerful means for the assembly and interpretation of evidence, and thus to address critical questions about issues such as crime and deprivation, immigration and demographic restructuring, retailing activity and employment change, resource management and environmental improvement. Many of these issues are equally important to academic research as they are to policy makers and Applied Spatial Analysis and Policy aims to close the gap between these two perspectives by providing a forum for discussion of applied research in a range of different contexts Topical and interdisciplinaryIncreasingly government organisations, administrative agencies and private businesses are requiring research to support their ‘evidence-based’ strategies or policies. Geographical location is critical in much of this work which extends across a wide range of disciplines including demography, actuarial sciences, statistics, public sector planning, business planning, economics, epidemiology, sociology, social policy, health research, environmental management. FocusApplied Spatial Analysis and Policy will draw on applied research from diverse problem domains, such as transport, policing, education, health, environment and leisure, in different international contexts. The journal will therefore provide insights into the variations in phenomena that exist across space, it will provide evidence for comparative policy analysis between domains and between locations, and stimulate ideas about the translation of spatial analysis methods and techniques across varied policy contexts. It is essential to know how to measure, monitor and understand spatial distributions, many of which have implications for those with responsibility to plan and enhance the society and the environment in which we all exist. Readership and Editorial BoardAs a journal focused on applications of methods of spatial analysis, Applied Spatial Analysis and Policy will be of interest to scholars and students in a wide range of academic fields, to practitioners in government and administrative agencies and to consultants in private sector organisations. The Editorial Board reflects the international and multidisciplinary nature of the journal.
