Since the liberalization of the grain market has been enhanced, competition between grain processing enterprises became fierce. After restructuring, many large scale processing enterprises have branched out. According to the statistics from China National Association of Grain Sector in 2005, there are 2,797 grain enterprises with daily processing capacity above 100 tons, and 8,321 enterprises with daily processing capacity below 100 tons, among which 7,260 are rice millers, 2,815 are flour millers, and 1,043 are vegetable oil crushers and refiners.
