Abstract: The paper analyzed the spatial and temporal evolution of “free” ratings pattern in Europe based on the data from Country Reports on Human Rights Practices of the U.S, economic sanctions and military interventions of western countries. In addition, this paper also explored the external driving mechanism of the spatial and temporal evolution of “free” ratings pattern in Europe. Conclusions are as follows: ①The Standard Deviation and Coefficient of Variation of “free” ratings in Europe declines, which means relative and absolute difference narrowing. ②The number of “free” country increases obviously, whose spatial distribution diffused from Southern, Western and Northern Europe to Eastern and Central Europe; The number of “partly free” country does not change basically, whose spatial distribution shifts from Central and Grand Duchies to Eastern and Southeast Europe; The number of “not free” country declines markedly, whose spatial distribution shifts from Eastern, Southeast and Central Europe to Belarus and Russia. ③The countries in Europe with similar “free” ratings tend to be concentrated in spatial distribution; There exits three aggregation modes: H-H aggregation regions located in Western Europe; L-L aggregation regions located in Eastern and Southeast Europe; H-L aggregation regions located in Southern, Central and Eastern Europe. ④The paper has explored out the external driving mechanism of the spatial and temporal evolution of “free” ratings pattern in Europe：Firstly, the U.S criticizes target countries in Country Reports on Human Rights Practices, which guides the evolution of “free” ratings pattern in Europe. Secondly, economic sanctions are the behavioral extension and concrete measure of the accusation for non-Western European countries in Country Reports on Human Rights Practices, which change the “free” ratings pattern in Europe indirectly. Lastly, military interventions change the “free” ratings pattern in Europe directly.
