Abstract

Today, transportation services are referred to as an industry in the world, which indicates the extent and importance of these services as a link between industries and a factor in the relationship between consumer and production markets. In this study, the Solow extended production function approach was used to examine the development of transportation infrastructure on the country's GDP, and the DeMello model was considered to estimate the effects of infrastructure development. For this purpose, the spatial panel method was used using provincial data from 1390 to 1401. The results of the study indicate that increasing investment in the transportation sector of each province led to the growth of the GDP of that province and an increase in freight and passenger traffic in a province led to a decrease in the per capita production of that province. Changes in the capital stock of the transportation sector of a province have a negative effect on the per capita production of other neighboring provinces. Also, the number of passengers transported in a particular province increases the per capita production in other neighboring provinces.
