In the early 1990s, Soviet Union and its allies launched large-scale reform of marketization and democracy, from the transition process of Soviet Union and its allies, we can find that there is a certain correlation between marketization reform support rate and democratic development satisfaction rate of the masses, because of different transition modes and different social and economic basis of different countries, however, there are different changing trends between the marketization support rate and democratic satisfaction rate of the masses when the reform brought many economic problems, those countries which have high rate of marketization reform support rate have made great progress in marketization reform, however, the satisfaction with the democracy more reflects the estimate on governmental performance by the masses but not on the evaluation on the political system. China’s transition development must consider the interactive influence between economic reform and democratic development and properly rationalize the relationship between reform and stability.
