Abstract: On the basis of the logic of economic analysis and the connotation of the related indexes, this paper constructs an index system for the measurement of the economic imbalance degree of a country so as to measure China’s economic imbalance levels since 2000. The results show that China’s overall economic imbalances have been worsening recently. The total index of internal and external economic imbalances increased from 0.3856 in 2001 to 0.5509 in 2010. Of which, the index of external imbalances increased from 0.2916 in 2001 to 0.4879 in 2010, and the index of internal imbalance increased from 0.4796 in 2001 to 0.6138 in 2010. China has to promote the policy coordination with other countries and rationalize the income-distribution relationship to expand domestic demands, so as to create the conditions to solve the problem of the internal and external imbalances.
