In the recent years, developments in the field of information and telecommunications are pursued by major changes in different areas of human life. Human has constantly employed the technology and track record of human life is abundant with innovation in information and communication technologies (ICT) which are called as new or high- technology. Therefore, ICT Development Indices (IDI) are remarkably important. This research purports to design a model of system dynamics (SD) on the policy of upgrading indices of Iran ICT network. Accordingly, after investigating the IDI and mining the indices, the causal loops and flowchart are depicted through using the SD (system dynamics). The results of simulation show that the behavior of studied key variables, after performing enhancing economic growth policies, improved the quality and quantity of ICT infrastructure, social indices, the culture of employing ICT, and the technical knowledge of ICT operators and the enhancing process has accelerated.
