In the following sentence:
计算机历史博物馆从1987年起每年颁发会员奖,授予其创意改变世界和影响今天所有人类的人。
The meaning would be something like the following:
The computer history museum issues the prize from 1987, giving it to people who changed the world and made an influence on all the people.
However, I don't understand what 其 here refers to. According to a dictionary, it means "that" or "it" or "theirs" or any such demonstrative pronouns, but in this case:
其 here refers to 会员奖 and 创意 is a verb, making the sentence 授予(V)会员奖(O)人(O)
创意 is a noun, and 其 modifies 创意, making the sentence 授予(V)其创意(O)人(O)
Or anything others that I missed
Which is the correct decomposition of grammar in this sentence? And generally how should 其 be used in these cases?
