Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of production capacity. In the context of scientific carbon reduction, coal consumption will continue to dominate for a long time, and the scarcity of new batches of production capacity will drive up asset prices. The core increase in demand is provided by traditional energy sources, driving oil and natural gas prices to continue to rise, and overseas coal prices hitting new highs. The rise in coal prices will also drive up the price of white cement.
