A good harvest is key to preventing grain price fluctuations. But macro control policies at the wholesale market level are also pivotal.

It's one month to go before the Autumn harvest, and the grain stock has almost run out.

This period is considered the most difficult time, and grain prices are expected to rise in the future.

Cheng Guoqiang, Researcher of State Development Research Center said "It's crucial to control the grain prices in such a key period, because grain prices now will influence the prices of autumn grain. So if we could control the current grain price by macro control measures, the prices of autumn grains will be stable."

The Country Grain Center in Hefei, capital of Anhui province, is the major platform for the nation's macro control policies. It runs a national grain trade platform together with 23 provincial level wholesale markets, which effectively control the grain prices.

Ge Liang, Vice GM of Country Grain Center, Hefei said "We have adopted a series of measures, including directional sales, checking and ratifying the purchase amount, and enhancing supervision towards delivery from storage. And our prices remain basically stable."

Expert also say China has had a reasonable grain harvest for 6 straight years, so the storage is enough to control the market prices. Even so, experts suggest the government continues its measures to prevent speculation.
