Effect of Infrastructure Investment and Freight Accessibility on Gross Domestic Product: A Data-Driven Geographical Approach

Abstract

Freight transportation can be defined as the movement of goods and services to customers to obtain a monetary reward. Poor quality transport infrastructure implies higher travelling times and costs. This indirectly affects the productivity of a region since transportation costs are directly related to sales prices. Therefore, infrastructure investments become important for improving the competitiveness of a region. The problem with these investments is that they take time and require a large amount of money. Consequently, it is extremely important to prioritise this type of investment. This paper will first explain whether transportation investment or a sustainable transportation method affect the exported freight accessibility and if it also affects regional productivity using a linear regression model with the aid of a data-driven geographical information system. It uses spatial separation, gravity, and cumulative opportunity measures to calculate accessibility. Finally, the paper denotes which regions are highly affected by improvements in road, river, and railway networks using Colombia as a case study. The comparison considers travelling time and costs savings under each scenario. The results indicate that the gravity measure was the most appropriate accessibility measure for analysing the Gross Domestic Product (GDP). The scenario analyses suggest that zones farthest from the seaports are more sensitive to accessibility changes; consequently, they will receive higher improvements in their regional GDP with a national-level implementation of transport infrastructure investments. Thus, project prioritisation should be performed in regions where the investments lead to a decreased travel cost between regions and ports.

Gestión de procesos de proyectos de inversión pública regional en la mejora de la infraestructura vial en una región de Perú

“…De ambas apreciaciones existen complementariedad entre ellas. Asimismo; estos resultados como se exponen se relacionan con la información presentada por Jubiz et al, (2021), donde la infraestructura vial es vital para la operación logística de un país, afecta indirectamente la productividad de una región ya que los costos de transporte están directamente relacionados con los precios de venta, por lo tanto, las inversiones en infraestructura se vuelven importantes para mejorar la competitividad de una región, en consecuencia, es de suma importancia priorizar este tipo de inversión.…”

“…Teniendo en cuenta, Hammes (2021), concluye que, el gobierno influye en la construcción de infraestructura vial en una dirección más sostenible desde el punto de vista ambiental (peatones y bicicletas), los proyectos suecos están impulsados por los municipios, mientras que el sistema noruego se basa en negociaciones recíprocas entre los municipios, el condado y el estado. Como dice, Jubiz et al, (2021), concluyeron que, la infraestructura vial es vital para la operación logística de un país, afecta indirectamente la productividad de una región ya que los costos de transporte están directamente relacionados con los precios de venta, por lo tanto, las inversiones en infraestructura se vuelven importantes para mejorar la competitividad de una región, en consecuencia, es de suma importancia priorizar este tipo de inversión, la medida de gravedad fue la medida de accesibilidad más adecuada para analizar el Producto Interno Bruto (PIB), en Estados Unidos, la priorización de proyectos debe realizarse en regiones donde las inversiones conducen a una reducción de los costos de viaje entre regiones.…”

The Relation Between Road Infrastructural Development and Land Value Increments in Dire Dawa City, Ethiopia

“…For all of Dire Dawa 76,815 households were counted living in 72,937 housing units, which result in an average of 4.5 persons to a household, with urban households having on average 4.2 and rural households 4.9 people. Ethnic groups in the region include the Oromo (45%), Somali (35), Amhara (13%), Gurage (3%), and Harari (1%). The region with the most believers in dire dawa is Muslim with 70.8%, 25.71% are orthodox, 2.81% protestant, and 0.43% catholic.…”

“…The final reason provided from the respondents for the expansion of road infrastructure is since infrastructures are an indicator of civilization, if the city has access to modern types of road infrastructure it will become more developed, attractive and productive. [35] Stated that the quality and types of nation's infrastructure is a critical index of its economic vitality. Reliable transportation is one of the basic elements of a civilized society and a productive economy.…”

The Impact of Expressway Development on Industrial Structure in Rugged Terrain: The Case of Sichuan Province, China

“…However, Jubiz-Dia et al proposed that owing to "diminishing marginal propensity to consume" and "constant marginal return on capital", the role of transportation infrastructure in promoting economic growth will only be short-term, not long-term [9]. The interaction between economic growth and infrastructure investments can be described through the use of accessibility indicators [10]. Reachability refers to the difficulty of moving from the starting point to the destination by rail and road transport [11].…”
