Some countries with good economic growth reduce their military budget. However, some more developed countries even increase their military budget. In addition, some less developed countries yet rise promote their military development. This study is aimed to examine the relationship between economic growth, information techology such as internet and mobile phone and military development.  The data used came from the World Development Data of the World Bank covering 260 countries in the world and employing panel data regression usinf the fix effects model. The dependent variable is the military expenditure (current USD) and the independent variables are GDP (current US$) and the number of mobile cellular subscriptions.

An increase of one US dollar in GDP is associated with an increase of US$ 0.0109002 in military expenditure (current USD). Meanwhile, an increase of one unit of mobile cellular subscription is related with  an increase of US$ 38.28941 in military expenditure.
