成立一般用在具体的（concrete）事物上，建立可以用在比较抽象的（abstract）事物。

hi 1 google成立于1998年。 google建立于1998年。 （意思一样 same meaning） 2 表示证据，理论有根据用“成立”（we use the word "成立" to indicate that this theory or proof is valid.） For example：(1) 法官确认律师反对成立。The judge sustained the lawyer's objection.

I can tell you a very easy way to distinguish the two words: 成立： a verb for some actions 建立： a verb for some ideas or some thoughts 成立学校 成立研究所 建立关系 建立友谊 by the way, there is another word: 组建 when some parts unite together and become an entirety, we use this verb for example, 组建政府 (政府: governement, it is made of several parts.)

成立’subject is something,such as company.建立’subject is someone.

简单的来说成立 就相当于 被建立。
