This article tests for the random walk hypothesis in the four Chinese stock markets of Shanghai "A," Shanghai "B," Shenzhen "A," and Shenzhen "B" and explores the impact of the market liberalization that occurred in 2001 on the efficiency of these markets. Empirical results show that the market liberalization in 2001 has a significant effect on the efficiency of Chinese stock markets.
