Serial number
Calculation formula
1
The proportion of coal consumption = coal consumption of industries/coal production
2
The proportion of the electric power consumption of coal industries = electric power consumption of coal industries/the electric power generated by electric power industries
3
The cost saved in the internal transactions of coal-electric industries = the price difference of electric power in the internal and external transactions of enterprises × power consumption of coal industries + the price difference of coal in the internal and external transactions of enterprises × coal consumption of electric power industries
4
The cost saved through the use of self-produced coal = the price difference of coal in internal and external transactions × coal consumption of chemical industries
5
The proportion of the value of the building materials utilized in coal industries = the value of the building materials used in coal industries/the total output value of the building material industries
6
The cost saved in the internal transactions of coal-building materials industries = the price difference of coal in the internal and external transactions of enterprises × coal consumption of building material industries + the price difference of building materials in the internal and external transactions of enterprises × the amount of the building materials utilized in coal industries
7
The proportion of the self-transported coals = the amount of self-transported coal/the total transport volume of enterprises
8
The cost saved in the internal transactions of coal-transportation industries = the price difference of coal in the internal and external transactions of enterprises × coal consumption of transportation industries + the price difference of the transported coal per ton in the internal and external transactions of enterprises × the transport volume of coal industries
9
The proportion of the value of the steel utilized in coal industries = the value of the steel utilized in coal industries/the total output value of steel industries
10
The cost saved in the internal transactions of coal-steel industries = the price difference of coal in the internal and external transactions of enterprises × coal consumption of steel industries + the price difference of steel products in the internal and external transactions of enterprises × steel consumption of coal industries
11
The proportion of the value of the equipment utilized in coal industries = the value of the equipment utilized in coal industries/the total output value of equipment manufacturing industries
12
The cost saved in the internal transactions of coal-equipment industries = the price difference of coal in the internal and external transactions of enterprises × coal consumption of equipment industries + the price difference of equipment products in the internal and external transactions of enterprises × the amount of the equipment utilized in coal industries
