چکیده:
Introduction: investment is one of the most important components of today’s modern
society. The key role that investment plays in the formation of the economic structure of a
society has made it a main focus in most of the economic discussions about the role of
infrastructural investment. Direct investments on infrastructures paves the way for
production facilities, stimulates economic activities and also improves competitiveness by
reduction the costs of business and transportations. However, over the past few years, since
the developed countries have undergone some technological advancements and evolutions in
fields such as new methods of production and storage, electronic business and since these
countries have paid special attention to the external effects of this infrastructure especially in
the environment, a new view has been developed which is based on the decrease in the
effectiveness of the relationship between investing in this infrastructure and economic
growth among economists. However, in developing countries, this view doesn’t hold true
because this infrastructure has not been sufficiently developed in these countries.
Research method: the present study aims to review the effect of infrastructural investment
on Iran’s economic growth. In this respect, the production function economic growth model
has been expressed and infrastructural investment has been reviewed as an important
infrastructure as an overall variable. In order to identify the effect of the infrastructures on
Iran’s economic growth, two variables have been used, i.e. physical infrastructures and
Information and Communication Technology. In order to estimate the aforementioned
model, the autoregressive disturbed lag method in the time span of 1983 to 2013.
Conclusion: the findings of this research have shown that in this specific time period, the
reviewed infrastructures including Information and Communication Technology and
physical infrastructure have had a positive and significant impact on Iran’s economic
growth.

The impact of ICT inventory on the economic growth At Yt in Iran in the long-term and the short-term is positive and significant.
The impact of physical infrastructures on the economic growth in Iran in the long-term and the short-term is Yt At Lt Yt .
In the present study, the effect of physical infrastructures as an overall variable on economic growth has been reviewed.
Here, the value of the calculation statistic based on this method is equal to: UCT Journal of Management and Accounting Studies Vol 5 Issue 2, June 2017 p results of the long-term test of the model, it becomes clear ˆi 1 t i 1 Sˆ i 1 t 0 / 1797 1 0 / 1789 4 / 5852 that in the long-term, the coefficients of the variables in [table 2] can indicate extension.
The results obtained from the estimation of the long-term model for the production function have been presented in [table 2].
The research results are indicative of the positive and significant effect of information and communication technology (ICT) on gross domestic production.
