As shown in Figure 3, there is an excess capacity of coke in China. Since 2008, the output of coke has greatly increased. From 20 12 to 10, China's coke output was 36.849 million tons, up 6% year-on-year; During the period of 1- 1, the coke output was 369.285 million tons, up 4.2% year-on-year. In June of 20 12, China exported 50,000 tons of coke and semi-coke and 9 1 10,000 tons of coke and semi-coke in June of 20 10, a decrease of 2.2 million tons compared with 3110,000 tons in the same period last year, with a drop of 70.8%. The export value is18.746 million USD. This year, the cumulative export value of coke and semi-coke is 40 1.774 million USD, which is 7 1.4% lower than that of last year.

90% of coke is used for smelting steel, so the output of steel almost determines the demand for coke. With the acceleration of investment in fixed assets and the growth of steel production and sales, the demand for coke will increase and the price of coke will rise.
