Modeling and Analysis of Interaction Between Power Industry and Typical Upstream and Downstream Industries

After the implementation of the power market construction, the impact of the power industry on the upstream and downstream high power consumption industries is mainly reflected in two aspects: electricity price and electricity consumption. In order to analyze the relationship between power and the development of related industries, the survey data of enterprise a is selected from the nonferrous metal smelting and rolling processing industry, and the multiple regression model of the influencing factors of enterprise output, power consumption and profit changes is constructed and analyzed. It is concluded that the main factors affecting enterprise output are cost, power consumption and profit Profit and electricity price, the main factors affecting the power consumption of enterprises are output and cost. The main factors that affect the profits of enterprises are cost and output. Finally, through vector autoregressive model, cointegration test, Granger causality test, impulse response analysis and variance decomposition, this paper empirically analyzes the relationship between the added value, power consumption, electricity price, raw material purchase index, ex factory price and steel output of non-ferrous metal smelting and rolling processing industry.
