摘要: 交通基础设施对城市经济发展具有强大的推动作用,尤其是大型交通基础设施的建设,对土地利用和空间形态产生重大影响。针对城市交通基础设施广义经济效益评估分析需求,本文提出基于城市经济土地利用-交通整体规划(Urban-Integrated Economy, Land Use, and Transport, U-IELUT)建模的交通基础设施广义经济效益评估框架和方法。在传统“四阶段”交通规划模型的基础上,加入城市经济和人口预测、社会经济活动空间分配、城市空间开发,以及交通基础设施广义经济效益评估模块,构建面向交通基础设施广义经济效益评估的“PECAS+(Production,Exchange and Consumption Allocation System)”广义经济效益评估模型。以武汉地铁2号线为例,基于武汉“PECAS+”广义经济效益评估模型测算其直接经济效益和广义经济效益。结果表明,地铁2号线在2027年的直接经济效益约为10.43亿元;广义经济效益中,动态集聚效益约为2.64亿元,约为直接经济效益的25.3%,说明广义经济效益尤其是集聚效益等带来的经济效益不可忽略。同时,还探明交通基础设施建设对不同小区的影响差异,即广义经济效益的空间分布,可为交通基础设施投资建设提供多维度决策支持。

Abstract: Transportation infrastructure has a strong driving effect on urban economic development. In particular, the construction of large-scale transportation infrastructure can have a significant impact on land use and spatial form. In response to the need for a comprehensive assessment of the economic benefits of urban transportation infrastructure, this study proposes a framework and method for assessing the Wider Economic Benefits (WEBs) of transportation infrastructure based on the Urban-Integrated Economy, Land Use, and Transport (U-IELUT) modeling. This study extends the traditional "Four-Step" transportation planning model to a "PECAS+(Production, Exchange and Consumption Allocation System)" WEBs assessment model by linking it with an economic and population forecasting, a socio-economic activities allocation, a space development, and a wider economic benefits assessment module. The WEBs assessment model is designed to evaluate both the direct economic benefits and the wider economic benefits, mainly the agglomeration benefits, of urban transportation infrastructure. Taking Wuhan Metro Line 2 as an example, the direct and wider economic benefits were assessed using the "PECAS+" wider economic benefits assessment model. The findings indicate that the direct economic benefits of the Metro Line 2 in 2027 are approximately 1.043 billion yuan. The dynamic agglomeration benefits are about 264 million yuan, which is approximately 25.3% of the direct economic benefits. This demonstrates that the wider economic benefits, especially the agglomeration benefits, should not be overlooked in the economic benefits assessment of transportation infrastructure. Meanwhile, it is also possible to ascertain the impact differences of transportation infrastructure construction on various zones of the study area, that is, the spatial distribution of wider economic benefits, which can provide multidimensional decision-making support for the investment and construction of transportation infrastructure.
