Explanatory Notes on Main
Statistical Indicators
Total
Energy Production refers to the total production of
primary energy by all energy producing enterprises in the region in a given
period of time. It is a comprehensive indicator to show the capacity, scale,
composition and development of energy production of the region. The production
of primary energy includes that of coal, crude oil, natural gas, hydropower and
electricity generated by nuclear energy and other means such as wind power and
geothermal power. However, it excludes the production of fuels of low calorific
value, bio-energy, solar energy and the secondary energy converted from the
primary energy.
Total
Domestic Energy Consumption refers to the total
consumption of energy of various kinds by material production sectors, non
material production sectors and households in the region in a given period of
time. It is a comprehensive indicator to show the scale, composition and
development of energy consumption. The total energy consumption includes that
of coal, crude oil and their products, natural gas and electricity. However it
excludes the consumption of fuel of low calorific value, bio-energy and solar
energy. Total domestic energy consumption can be divided into three parts:
(1) Final Energy Consumption: It refers to
the total energy consumption by material production sectors, non material
production sectors and households in the region (region) in a given period of
time, but excludes the consumption in conversion of the primary energy into the
secondary energy and the loss in the process of energy conversion.
(2) Loss During the
Process of Energy Conversion: It refers to the
total input of various kinds of energy for conversion, minus the total output
of various kinds of energy in the region in a given period of time. It is an
indicator to show the loss that occurs during the process of energy conversion.
(3) Energy Loss: It refers to the total of
the loss of energy during the course of energy transport, distribution and
storage and the loss caused by any objective reason in a given period of time.
The loss of various kinds of gas due to gas discharges and stocktaking is
excluded.
Elasticity
Ratio of Energy Production is an indicator to show
the relationship between the growth rate of energy production and the growth
rate of the national economy. The formula is:
Elasticity Ratio of Energy
Production=Average Annual Growth Rate of Energy Production/Average Annual
Growth Rate of National Economy
The average annual growthrate
of the national economy can be shown by the gross national product, gross domestic
product and other indicators, depending upon the purposes or needs. The gross
domestic product is used in calculation of the ratio in this chapter.
Elasticity
Ratio of Electricity Production is an indicator to
show the relationship between the growth rate of electricity production and the
growth rate of the national economy. Generally speaking, the growth rate of
electricity production should be higher than that of the national economy.
Its formula is:
Elasticity Ratio of Electricity
Production=Average Annual Growth Rate of Electricity Production/Average Annual
Growth Rate of National Economy
Elasticity
Ratio of Energy Consumption is an indicator to show
the relationship between the growth rate of energy consumption and the growth
rate of the national economy. The formula is:
Elasticity Ratio of Energy
Consumption=Average Annual Growth Rate of Energy Consumption/Average Annual
Growth Rate of National Economy
Elasticity
Ratio of Electricity Consumption is an indicator to
show the relationship between the growth rate of electricity consumption and
the growth rate of the national economy. The formula is:
Elasticity Ratio of Electricity
Consumption=Average Annual Growth Rate of Electricity/Average Annual Growth
Rate of National Economy
Efficiency
of Energy Processing and Conversion refers to the
ratio of the total output of energy products of various kinds after processing
and conversion and the total input of energy of various kinds for processing
and conversion in the same reference period. It is an important indicator to
show the current conditions of energy processing and conversion equipment,
production technique and management. The formula is:
Efficiency of Energy Processing &
Conversion=Output of Energy After Processing & Conversion/Input of Energy for
Processing & Conversion×100%
Energy
Consumption per Unit of GDP refers to the energy
consumption per unit of gross domestic production in a country or the gross
region production in a region in the same reference period. The formula is:
Energy Consumption per Unit of GDP=Total
Energy Consumption/Gross Domestic Production
Electricity
Consumption per Unit of GDP refers to the
electricity consumption per unit of gross domestic production in a country or
the gross region production in a region in the same reference period. The
formula is:
Electricity Consumption per Unit of
GDP=Total Electricity Consumption/Gross Domestic Production
Electricity
Consumption per Unit of Industrial Value-added
refers to the energy consumption per unit of industrial value-added in a
country or region in the same reference period. The formula is:
Energy Consumption per Unit of Industrial
Value-added=Total Energy Consumption/Industrial Value-added
Energy
Consumption per Unit of GDP refers to the energy
consumption per unit of gross domestic production in a country or the gross
region production in the same reference period. The formula is:
Energy Consumption per Unit of GDP=Total
Energy Consumption/Gross Domestic Production
Electricity
Consumption per Unit of GDP refers to the electricity
consumption per unit of gross domestic production in a country or the gross
region production in the same reference period. The formula is:
Electricity Consumption per Unit of
GDP=Total Electricity Consumption/Gross Domestic Production
Energy
Consumption per Unit of Industrial Value-added refers
to the energy consumption per unit of industrial value-added in a country or
region in the same reference period. The formula is:
Electricity Consumption per Unit of Industrial Value-added=Total Energy Consumption/Industrial Value-added
