Africa's markets are weak not only because of weak infrastructure in terms of roads and telecommunications, but also because of the virtual absence of necessary market institutions, such as market information, grades and standards, and reliable ways to connect buyers and sellers.
非洲市场的不发达不仅是因为基础建设 如公路和电信，不完备，更因为 其缺乏所需的市场组织，比如 市场信息，评级和标准， 以及联系买卖双方的可靠方式。
