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
