The Black Market and the Oil Price in China

The Black Market and the Oil Price in China
The Chinese government set a price ceiling of gasoline, but the price which was set by Chinese government is lower than cost price. Because of this situation, the petroleum companies decrease the supply, but the price still at that price, therefore, many car and track cannot get gasoline. Now, there is a black market appeared, some people see that situation, and thought it was a chance to make money. First, they went to a gasoline station to buy much gasoline, than when the station run out of oil, they bring the gasoline that they brought before and sell the gasoline the station or drivers at a much higher price.
The government had to free the price of gasoline; it is the most effective way to solve the problem. Because if the oil companies can sell the oil at a higher price and get more benefit, they will produce more oil, so the people who buy and sell gasoline illegal does not have any benefit, and the situation will be stopped.
