However, information exchange behaviors of industry association will have double and legal effect on market and competition, which can not only promote the communication among members of the industry to find a solution to the industry benefit maximization, but also can produce inhibition and barriers to competition in the market. So in this paper, the industry association analysis will be made on the pros and cons of the information exchange, and the legislative defects and the insufficiency of information exchange industry association in our country. According to the practice in our country, the author puts forward the system design of our country industry association information exchange behavior.展开更多
