HONG KONG (China), Denmark and Sweden are the top three regions in the International Telecommunication Union (ITU) Mobile-Internet index, according to a new ITU research book released yesterday.

　　Their Mobile-Internet scores are 65.88 for Hong Kong, 65.61 for Denmark and 65.43 for Sweden. They were followed by Switzerland, the United States, Norway, South Korea and the United Kingdom.

　　The index measures how each of more than 200 economies is performing in terms of mobile and Internet technologies and how likely they are to take advantage of new developments in this field.

　　Each economy's score on the Mobile-Internet Index is measured on a scale of 0 to 100.

　　According to ITU, the index covers 26 variables in three groups. These are infrastructure, usage and market structure, which include fixed lines per 100 inhabitants, mobile phone subscribers per 100 inhabitants and the number of ISPs in the country.

　　The ITU report shows that teenagers appear to be the most avid users of the mobile Internet, notably in markets where it is at an advanced stage of development, such as South Korea and Japan.

　　According to the ITU press office, the new ITU report will be submitted to the 16th ITU Plenipotentiary Conference to be held in Marrakesh, Morocco next week.
