The effect of porf price rising in China

Recently, the pork rising in price has aroused the entire country's attention. I think there are three reasons of it. First, the feeding cost rises in price, especially corn price rising fast. This is the most important reason of causing the pork price rising. However, the corn price rising is also caused by the international crude oil rising in price. Second, the Chinese economy continues to prosper in recent years and the national income has increased so fast that the quantity of pork demand is rising accordingly. Third, it is said, because the demand quantity increases, supply is to be slightly insufficient. To a certain extent, it has risen the retail price.
