Economic Factors in Determining the Penetration Coefficient of Mobile Phone in Iran

In this paper we have studied the adoption rate of mobile phone in Iran via the new technology diffusion models approach. The result show that its diffusion pattern has a S shaped curve which is consistent with logistic model. Effective factors in diffusion pattern are: population, GDP, digitalization of the telecommunication system, government expenditures on the telecommunication sector, price of mobile phone and the inflation rate. We have also found that the logistic model has a batter explanatory power than the time series models.
