Economic Analysis Model On The Prices Chain Relationship Between Coal And Electric Power Industry

Status of coal in China’s energy structure is very important, in recent years, the consumption of coal resources in China up to half the world’s total coal consumption for the first time, coal supplies stability has an important impact on China’s energy security, especially in the power generation sector, in our country, consumption of coal resources for power plants accounted for more than70%of total coal consumption. Therefore, studying the effects of coal price fluctuation on power generating enterprises is significant, how to coordinate the price transmission between coal and electricity enterprises, balance development between the coal and electricity enterprises, have important significance on China’s economic development and energy security.This article made a detailed study of coal market in China, including distribution characteristics of coal reserves, coal base construction, supply chain, coal prices, coal supply chain evolution mechanism, and so on, fully introduced the development and utilization of coal resources in China, as well as planning for the rational use of coal resources. Second, focus on power coal for the status quo, based on the analysis of electric power industry of coal consumption and their cost, also supply and demand for steam coal in China this year were studied, calculated the power coal shortage in China, based on the analysis of the data, using grey-regression models to predict the thermal coal prices in China. Finally, build the coal price fluctuations on power generation enterprise cost model on the analysis of changes and impact on electricity tariff models, and based on the analysis of influencing factors on coal prices, construction of coal-fired electricity price chain system dynamics model of the relationship, in order to research coal-fired electricity price transmission subsystems in the overall macroeconomic.
