The US and Scandinavian countries top the annual rankings on the usage of telecoms technologies such as networks, mobile phones and computers, according to this year's Connectivity Scorecard.
The Scorecard was created by London Business School professor Leonard Waverman last year and measured 50 countries on dozens of indicators, including technological skills and usage of communications technology.
Researchers said the new indicator - already used by several countries in developing innovation strategies - showed there was plenty of room for improvement in infrastructure and usage in all countries.
Professor Ilkka Lakaniemi, head of global political dialogue at Nokia Siemens Networks, which commissioned the study, said the focus has been on infrastructure, but he added investment in teaching was essential if countries wanted to boost competitiveness.
Countries in eastern and southern Europe, including Italy, Spain, Greece, Poland, just made it into the top 25 most technologically developed countries.
Here's the top ten:
UNITED STATES 7.71
SWEDEN 7.47
DENMARK 7.18
NETHERLANDS 6.75
NORWAY 6.51
BRITAIN 6.44
CANADA 6.15
AUSTRALIA 6.14
SINGAPORE 5.99
JAPAN 5.87
