It uses economic growth convergence theory as the basis and makes use of actual statistical data over the years from many countries as well as the Digital Opportunity Index (DOI) to conduct quantile regression analyses to examine what impact information technology has on different income growth quantiles. Empirical results show that the real initial GDP all the coefficients are negative in value, which indicates economic convergence. We also find that for countries in the low and medium quantiles, the DOI has significant positive impact on economic growth rates. On the other hand, countries in the high quantile are under 10% of the level of significance and the DOI has positive impact on economic growth rates. What remains interesting is that for countries in the high-intermediate quantile, the level of digitization has little and insignificant impact on individual income growth. This proves that countries with low level of digitalization can elevate their incomes through information technology and the effect is much higher than countries with higher levels of digitization. Therefore we can infer that in countries in the high quantile, there exists complex and diversified factors of economic growth and the effect of using digitalization alone to enhance economic growth is limited.
