Abstract

The road transport sector is a fundamental prerequisite and infrastructure for economic development. The New Economic Geography (NEG) literature suggests that transportation cost is a major driving factor for a country's emergence of core-periphery patterns. The aim of this research is the impact of road transport infrastructure on the spatio-temporal development of the cities of Khuzestan province. The research data for the period of 2010-2019 for 27 cities of Khuzestan province is in the form of panel data, which was used to investigate the temporal and spatial effects of the generalized method of moments (GMM). The variables used in this study are the Hubness index, market potential, road transport infrastructure variables such as the length of the sly and subway roads, and the displacement of goods and passengers. The estimation results show the positive effects of the Hubness index and Market potential index on the size of the cities of Khuzestan province. So that the Market potential variable shows more effects than the Hubness index on the development of the cities of Khuzestan province, this survey confirms that the transportation infrastructure in the period of 2011-2020 has been able to improve the spatial-temporal development in the cities of Khuzestan province. Also, side roads and the movement of goods as control variables have shown a positive effect on the development of the cities of Khuzestan province.
