| In January 2021,the China Business Intelligence Network conducted statistics on the production of crude salt in 2020 and in February 2021 Xinhua News Agency published an article on the price index of China Salt and Alkali Industrial Salt.According to the data in the article,it was found that China Salt The price index of two-alkali industrial salt declined,and the decline of the price index to a large extent means that the market is saturated.The state has become more and more stringent in the control of self-provided power plants.Therefore,is the self-provided power plant of salt chemical enterprises worth investing?This article will use the payback period to analyze whether the captive power plant is worth investing,but in the early stage of investigating whether it is worth the investment,apply the incentive regulation model to establish the salinization enterprise captive power plant investment model and the Stankelberg model to establish the salinization enterprise power generation company The cooperation model is the scientific theoretical basis for some parameters in the study of investment payback period.First,in the case of investing in a captive power plant,the incentive regulation theory is used to establish a captive power plant commissioned management model,and the incentive regulation theory is applied to analyze the application of incentive regulation theory pricing strategies in the collaboration between the salt chemical enterprise and the captive power plant,which proves that it can stimulate The captive power plant reports its true level and encourages the captive power plant to take active measures to reduce costs and obtain the benefits and cost parameters of the investment in the captive power plant.Secondly,without investing in self-provided power plants,use the Stackelberg theory of game theory to establish a model for cooperation between salt chemical companies and power generation companies,and consider adding government cost subsidies and environmental protection subsidies separately.Through calculation,it is concluded that the optimal profit decision of salt chemical enterprises is more inclined to the cost subsidy policy under the fixed steam price model dominated by power generation enterprises.Finally,according to the previous captive power plant commissioned business model to obtain the optimal income of the salinization enterprise and the power generation enterprise cooperation to obtain the optimal income of the salinization enterprise,a comparative analysis is carried out,and the income of the captive power plant and the power generation enterprise is analyzed using the investment payback period.The captive power plant is worth the investment.However,relatively speaking,investment in self-supplied power plants has a longer period of benefit balance compared with cooperation with power generation companies.Therefore,the investment decision of self-supplied power plants of salt chemical companies needs to be carefully considered.The research significance of this paper is in theory: in terms of investment payback period,the application of incentive regulation theory to establish a model provides scientific theoretical basis for the basic parameters of investment payback period.In terms of incentive regulation theory,it is applied between companies with certain management and control rights,which broadens the scope of application to a certain extent. |
