It finds that: (1) when the companies´ information transparency rating is high or increasing, the proportion of institutional ownership is higher and the number of institutional investors is larger, or institutions investors would increase the shareholding and the number of institutional investors;(2)when the companies´ information transparency rating is high or increasing, the proportion of short-term institutional ownership is higher or it would increase the shareholding ;(3)when the companies´ information transparency rating is high, the proportion of long-term institutional ownership is higher.
