| With the implementation of the scientific outlook on development and "low-carbon economy",the coal industry,as a traditional energy,is facing new survival problems.Therefore,it is necessary to adopt reasonable methods to evaluate the performance of coal enterprises,analyze the performance of enterprises since the implementation of "de capacity",objectively evaluate the effect of policies,find the shackles of the development of coal industry represented by case enterprises and behind them,and provide guidance for the future development of coal enterprises.Inner Mongolia Huineng Coal Power Group Co.,Ltd.(hereinafter referred to as "Huineng coal power group")is selected as the research object to evaluate its performance.From the five aspects of economic benefits,resource exploitation,scientific and technological innovation,market vitality and social relevance,this thesis constructs the performance evaluation index system of Huineng group from the perspective of "de productivity",calculates the weight of each index by using entropy weight method,and obtains the performance evaluation value by TOPSIS method.It is found that there is an obvious fluctuation trend in the performance of Huineng group.Before de capacity,the group’s comprehensive performance decreased significantly;The implementation of the "de capacity" policy has led to a significant recovery in the group’s performance;However,in recent years,the group’s performance began to decline.it is found that the current performance development of the group is mainly faced with low cost profit margin,high debt ratio and;Limited resource exploitation level;Low comprehensive utilization rate of waste;Lack of market competitiveness;Low level of diversification;Insufficient R & D capability;Less government support and other obstacles.Based on this,combined with the overall operation status of the group,this thesis puts forward some countermeasures to increase the competitiveness of the group and improve the overall performance level,such as optimizing the capital structure,strengthening cost control,building concentric diversification,expanding market share,striving for policy support,strengthening innovation vitality,scientific resource exploitation and improving comprehensive utilization. |
