High quality information technology and investment decisions

Investment decisions are one of the most important decisions that companies make. With better information, managers need to make more informed decisions that lead to better results. The present study investigates the effect of information technology on the investment decision of companies listed on the Tehran Stock Exchange. For this purpose, information related to 140 companies active in the stock exchange during the years 1392 to 1397 was collected and statistically analyzed using Ivory statistical software. The research method is multiple regression and panel data. Based on the results of research and statistical tests, it can be said that there is a significant and negative relationship between information technology and abnormal investment. Also, due to the fact that over-investment and under-investment are considered as indicators of abnormal investment, a negative and significant relationship was found between information technology and over-investment. But no significant relationship was found between information technology and low investment. Information technology provides the basis for more timely collection and dissemination of information to managers, which leads to an increase in their ability to process and analyze information for decision-making, and this in improving the quality of decision-making. Getting managers is very effective
