Abstract This article is about the false, misleading advertising and harmful behavior to goodwill in China. Generally speaking, advertisement is the best marketing way and an unique characteristic in the West¡]always mean capitalist society¡^. And advertising is related to the anti-trust law that combines the science of law and economy. After 1979 PRC¡¦s reform, economical power¡]or the market¡^is the greatest concern in their policy-making. In 1987, PRC issued the formal statute of advertising in place of the interim procedures¡]1982¡^. But the first anti-trust law in the world is Sherman Act¡]1890¡^of USA. According to Sherman Act and the rule of ¡§true in advertising¡¨, FTC Act¡]1914¡^stops the false and misleading advertising in USA, because those are unfair competitions. All capitalist countries want a fair and faultless market. After comparing the law against false advertising in USA and Taiwan with China, we will observe how to enforce the anti-trust law. After understanding the differences of those laws in three countries, we could find out whether those work or not. Through the enforcements in these countries, we realize that the capitalist power often affects lawmaking a lot. Therefore, the governments should not neglect demand of market, especially in an immature capitalist society.
