Explanatory Notes on Main Statistical Indicators |
|
Total Energy Production refers to the total production of primary energy by all energy
producing enterprises in the country in a given period of time. It is a
comprehensive indicator to show the capacity, scale, composition and
development of energy production of the country. The production of primary
energy includes that of coal, crude oil, natural gas, hydro-power 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, nonmaterial production sectors and households in the country 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, nonmaterial production sectors and households in the
country(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 country 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 & Conversion100% |
