As an important social intermediary organization, trade association is possessed with powerful functions of serving, right safeguard, supervising, coordinating and so forth. Our country is a less advanced economic transition country. Due to relative legislation insufficiency of our trade association, ambiguity of legal status and shortage of law duty and so on, trade association has functional impediment, which is not conducive to the elaboration of trade association function. So it is imperative to regulate legislation system, make law status clear and definite as well as improving relative law duty system.
