The table above clearly refects the statistic of mobile phone subscription in developing and developed counties from 2000 to 2008.According to the diagram,in 2000,the mobile phone subscriptions in developing countries still at a low level,less than 0.5 billion.Surprisingly,it reached more than 3.5billion in 2008 within no more than 8 years.During this period,subscriptions related to developed country,however,were on a steady rise.
I assume there are at least two fundamental factors to account for the above-mentioned changes.First and foremost,from 2000,the rapid development of economy has occurred in developing countries,which leads to widespread acceptation of using mobile phone.In addition,developing countries’ population are much more than developed countries,which illustrates that developing countries’ market remains great potential.All these driving factors contributed a lot to the increase of mobile phone subscription in poorer countries.
From what has been discussed so far,we can conclude that the subscription of mobile phone is becoming a crucial element of our daily life.And the developing countries will keep pace with the development of world economy.
