A random utility based multiregional input-output approach to estimate the impact of a new highway on the regional distribution of jobs

摘要

This paper addresses the economic impact assessment of the construction of a new road on the regional distribution of jobs. The paper summarizes different existing model approaches considered to assess economic impacts through a literature review. Afterwards, we present the development of a comprehensive approach for analyzing the interaction of new transport infrastructure and the economic impactudthrough an integrated model. This model has been applied to the construction of the motorway A-40 in Spain (497 Km.)udwhich runs across three regions without passing thoughudMadrid City. This may in turn lead to the relocation of labor and capital due to the improvement of accessibility of markets or inputs. The result suggests the existence of direct and indirect effects in other regions derived from the improvement of the transportation infrastructure, andudconfirms the relevance of road freight transport in someudregions. We found that the changes in regional employment are substantial for some regions (increasing or decreasing jobs), but a t the same time negligible in other regions.udAs a result,the approach provides broad guidance to national governments and other transport-relatedudparties about the impacts of this transport policy.
