Another theoretical problem raised by the grain price data, also illustrated in Li´s article, is that of how to define and identify markets.

李明珠的文章也显示了另一个由谷物价格引发的理论问题，即如何定义和界定市场。

李明珠的数据表明，就19世纪的粗粮而言，也许四到五年就有这样一个截然不同的短期周期的出现；对此时期的小麦而言，可能有这较长的周期。

Li, in her article on Zhili, uses grain prices to test the impact of crises in several different ways.
