This paper develops spatial network metrics that contribute to analysis of regional development. We use the sDNA software to derive longitudinal road network density and efficiency measures based on the network within a 1-hr travel time buffer. We estimate this travel time itself from network shape and show it to be comparable to Google Maps travel time data. Economic analysis of 374 Local Administrative Units in the UK mainland shows cross-sectional association between our network density and efficiency measures and Gross Value Added per capita (GVApc), whether measured in bivariate correlation or in multiple regression controlling for population, education, economic activity rate and rail stations. This is however both mediated and moderated by the proportion of knowledge-based businesses; regions lacking a strong knowledge-based sector show only weak correspondence between GVApc and accessibility. Looking at change over time, increase in network accessibility is linked to growth in the knowledge-based sector, but inversely linked to economic performance during the 8-year period studied, a finding which remains unexplained. Although further substantiation is needed, results suggest that the policy of transport investment as a driver of UK economic growth may be less effective in areas lacking potential to develop a strong knowledge-based sector.

空间网络分析作为衡量随时间推移的可达性变化的工具:作为英国区域发展驱动力的交通投资限制

本文开发了有助于分析区域发展的空间网络指标。我们使用 sDNA 软件根据 1 小时行程时间缓冲区内的网络推导出纵向道路网络密度和效率度量。我们从网络形状估计这个旅行时间本身,并显示它与谷歌地图旅行时间数据相当。对英国大陆 374 个地方行政单位的经济分析显示了我们的网络密度和效率测量与人均总增加值 (GVApc) 之间的横截面关联,无论是通过双变量相关还是在控制人口、教育、经济活动的多元回归中测量率和火车站。然而,这受到知识型企业的比例的调节和调节;缺乏强大的知识型部门的地区仅显示 GVApc 和可访问性之间的弱对应。从随时间的变化来看,网络可访问性的增加与知识型部门的增长有关,但与所研究的 8 年期间的经济表现成反比,这一发现仍然无法解释。尽管需要进一步证实,但结果表明,作为英国经济增长驱动力的交通投资政策在缺乏发展强大知识型部门潜力的地区可能效果较差。
