| In the current economic environment,China’s main structural contradictions are characterized by excessive stocks represented by the real estate,coal and steel industries,overcapacity,high production costs in various industries,and obvious shortcomings in certain areas.At present and in the next five years,coal is still China’s main energy source and important industrial raw materials.The coal industry is an important basic industry that is related to the country’s economic lifeline and energy security.It involves a wide range of employees and a large number of employees,which is related to the overall situation of economic development and social stability.In recent years,affected by factors such as slowing economic growth and adjustment of energy structure,the development of the coal industry is facing prominent contradictions and problems such as severe overcapacity,serious imbalance between supply and demand,dilemma in business operations,rising safety production risks and increased environmental protection pressure.Since 2015,as the country initiated structural reforms on the supply side,actively promoted capacity reduction and vigorously optimized the industrial structure,the deep-seated contradictions accumulated in the coal industry for a long time are gradually being solved.However,excessive cost and overcapacity are still one of the most prominent contradictions that currently restrict the development of the coal industry.This paper focuses on the cost management of coal enterprises in the context of supply-side structural reform.On the basis of cost management theory such as value chain management theory and coal cost life cycle theory,this paper studies the main problems of the main cost structure and cost management of Z coal enterprises,and the causes of losses in recent years,using new theoretical methods as the basis.Based on the theoretical basis,the data analysis method,the new and old contrast method are proposed to improve the cost management,and the new ideas of reducing the cost increase in the supply side background are summarized.First,attach importance to science and technology investment,promote product transformation,strengthen science and technology investment to extend the industrial chain or promote the transformation of coal products into clean energy.Second,in the process of cost reduction,coal enterprises should be guided by the longterm supply and demand of the coal market,combined with advanced cost management methods such as the target cost method,and continuously adjust costs and conduct cost management in economic activities.Third,they should actively cooperate with the government’s latest introduction.The policy focuses on government actions and seeks cost reduction measures both inside and outside the enterprise.By reducing costs and improving cost management,it is hoped that Z-coal enterprises and similar troubled enterprises will provide practical suggestions to improve and even get out of the dilemma. |
