Chart: World's most 'e-ready' countries

The second half of the most Web-savvy nations includes India, ranking 53, and China, 57. Although the study said the worldwide digital divide is narrowing, the difference between the list's Web-savviest nation, Denmark, and the least e-ready country of its top 68 countries, Azerbaijan, remains huge, with respective scores of 9 and 2.9 out of a possible 10.

In central and eastern Europe, mobile-phone penetration is ubiquitous, but fixed-line Internet connections are not widely available, while the business and legal environment can be weak. Overall, the region remains well behind developed markets in the European Union, North America and the Asia-Pacific region, according to the study.
