在市场经济条件下,商品以价格、质量进行竞争,而价格在某种程度上取决于产品的生产成本。成本的高低,决定着企业能否在价格上战胜竞争对手,进而决定着竞争的成败和企业的命运。从这个意义上说,煤炭商品的竞争,实质上也就是生产成本的竞争。那么,如何降低煤炭的生产成本,尤其是衰老矿井如何降低生产成本,以求得企业的生存和发展,是煤炭企业的领导者必须要研究和解决的重要课题。 In a market economy, the price of goods, quality competition, and the price depends to some extent on the production costs of the product. The level of cost determines whether the enterprise can defeat its competitors in terms of price, which in turn determines the success or failure of the competition and the fate of the enterprise. In this sense, the competition of coal products is essentially the competition of production costs. So, how to reduce the production cost of coal, especially how to reduce the production cost of aging mines in order to obtain the survival and development of enterprises, is an important issue that the leaders of coal enterprises must study and solve.
