There are so many scholars have conducted researches on whether China＇ s stock market has reached weak-form efficiency. The author of this literature review summaries the results of these researches and makes a systematic induction. This article attempts to show the achievements of these researches and ~ive readers new ideas about how to improve China＇ s stock market efficiency.展开更多
