Specifically, I will look at the reasons that led to the Chinese record industry＇ s gradual depression in the past thirty years. Additionally, I will show the important reasons why piracy is on a rampage in China, and explain why China has not been able to solve this problem. To do this, I will examine the data of CD sales and revenue of Chinese Records Company in recent years, to see what has changed.展开更多
