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) 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 growth rate 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%
