Sorry I cannot type Chinese.
象德州这样的个例也不能说明整个农产品市场的问题啊
TX is the second biggest agriculture state in US. I am talking about US security market, so I use US Agriculture business. The biggest one California. Farm there maybe smaller.However the minimium investment in typical mutual fund is 1000$-2000$, and minimium investment for T-bill/bond is 1000$. That's only 1/5 value of a cow. How many cow , land, equipment a rancher need to start milk business?
Come on get public financial data is almost free of cost. Farmer still need some money to get information of local price expectation, weather, or new technology, although it's low in US because of government substitution.
1.市场上有许多经济主体,这些经济主体数量众多,且每一主体规模又很小,所以,他们任何一个人都无法通过买卖行为来影响市场上的供求关系,也无法影响市场价格,每个人都是市场价格的被动接受者。散户是市场价格的被动接受者
Actually this is debateable. Because of government regulation such as no mutual fund can put more than 5?% of its money in any company, Cannot own more than 10?% of one company's stock, or after own 5% of one company's stock anyone have to anounce herself, etc. Mutaul fund does not has that much market power either. On the other hand, in agriculture product market, there are big buyers like Wal-Mart, or United, they have a lot of market power.
It happens in China too, http://bbs.cenet.org.cn/dispbbs.asp?boardID=92507&ID=49024
