| The climate problem caused by greenhouse gas emissions has seriously affected the production and life of human society.As a major carbon emitter,the steel industry is actively exploring low-carbon technology upgrading and emission reduction under the guidance of national policies.The decision-making of iron and steel enterprises is affected by many aspects.On the one hand,the investment in low-carbon technology is large,which is restricted by the scale and profitability of enterprises.On the other hand,the regulation of carbon emissions has not yet been strict.There is unfair competition in the market,which often leads to the expected income after upgrading low-carbon technology.Therefore,iron and steel enterprises have been in a wait-and-see state in upgrading low-carbon technology.In this context,this paper studies the strategic choice of low-carbon technology upgrading in steel enterprises.This paper takes the decision-making dilemma faced by the large typical steel enterprise J as the research entry point,considers the relationship between carbon quota and trade,market unfair competition and the choice of low-carbon technology upgrading strategy of steel enterprises,selects large and medium-sized steel enterprises as the research object,and establishes the game matrix between them,The equilibrium strategy evolution of low-carbon technology upgrading of iron and steel enterprises under the unfair competition environment and carbon quota trading mechanism is studied respectively.Combining the literature research method,field investigation method,evolutionary game method and simulation method,the following research conclusions are drawn:(1)The main influencing factors of low-carbon technology upgrading decision of iron and steel enterprises are the rate of income increase of low-carbon technology upgrading,emission reduction costs,corporate responsibility and brand reputation,unfair competition and carbon market transactions.Enterprises should fully consider the relationship between benefits and obstacles when making decisions.(2)When upgrading low-carbon technology,the leading large steel enterprises in the market will be more affected by unfair competition after increasing the rate of income increase,and the benefits of enterprises will be very small after reducing the rate of income increase.In this case,the government needs to carry out tangible hand control.(3)When the benefits of upgrading low-carbon technology are less than the sum of the input costs and the benefits of unfair competition,small and medium-sized steel enterprises pay more attention to profits and ignore carbon emissions,and will take advantage of unfair competition.The appearance of unfair competition will slow down the trend of large steel enterprises towards low-carbon technology upgrading.Small enterprises will choose low-carbon technology upgrading as soon as possible to try to overtake due to the influence of large enterprise strategies and their own interests.However,the market order will be damaged in the short term.In this case,the government needs to strengthen market supervision,and the total emissions of iron and steel enterprises can also be controlled through the carbon quota trading mechanism.(4)Carbon trading has a restrictive effect on unfair competition.The increase of carbon trading price will help promote the increase of carbon trading profits of both enterprises and the trend towards the best choice strategy.When the carbon trading price is higher,the two types of enterprises will choose to upgrade low-carbon technology as soon as possible.In addition,from the perspective of enterprise management,this paper puts forward suggestions for iron and steel enterprises to speed up the layout of low-carbon technology and strengthen the construction of low-carbon technology upgrading projects.At the same time,the government can provide more guidance and policy support in the construction of low-carbon projects and the promotion of low-carbon enterprises,and create a healthier environment. |
