The rating of three rating agencies is largely representing the developed countries, their rating methods are too stale and their monopoly position in credit rating market should be broken. In 2010, Dagong Global Rating Agency firstly announced its rating on 50 countries, trying to break the monopoly of the three rating agencies and their fixed rating model to establish a set of new rating system. The guiding ideas of Dagong Global Rating Agency to conduct sovereign credit rating are different from the three rating agencies, their core evaluation indicators are also largely different, as a result, their rating results are different. The rating on emerging countries with stable politics, excellent economy and good prospect by Dagong Global Rating Agency is higher than that of three rating agencies, however, Dagong’s rating on developed countries with slow economic development, heavier and heavier debt burden is obviously lower than that of the three, which reflect the basic difference of the ideas between Dagong Global Rating Agency and three rating agencies, Dagong does not regard ideology and political and economic system as evaluating standard but pays more attention to economic development prospect of a country.
