Why the primary data from enterprise is important?
Energy balance gives a whole picture of a
country’s energy supply and demand, the energy
transformation, and the relative importance of the
different fuel supplies in their contribution to the
economy. Therefore a good energy balance sheet
plays a significant role, but in order to compile a
good Energy balance sheet, first of all, the reliable
basis data of enterprises is a must.

The energy survey in industry sector
For the industrial enterprises above designated size,
we do comprehensive survey quarterly. The number of
these enterprise is about 300 thousand, their out put values
take up about 90% of whole industry sector.

Some related data resource
China’s energy statistics is in charge of the
energy purchase, consumption, storage, and
conversion. The gross industrial output value
and output of industrial products is collected by
other department of National Bureau of
Statistical of China. And we also get electricity
consumption data from China Electricity
Council.
The method of ensure the data
First, improve the data check program, and
ensure the primary data quality.
When the enterprise report the survey, we use
software to do the primary checking process.
We also explore timely and effectively the
inquiring methods, and continuously add the
checking factors so the data input mistake can
be find out quickly.
The method of ensure the data
Second, focusing on the key industrial enterprises.

Third, focusing the data evaluation on the district and city level.
In China, the energy statistics is reported level by level.

Fourth, enhancing the training to the junior officer of
energy statistics.
The Department of Energy
Statistics and each local
statistical bureau offered energy
statistical data processing
training program and many special
seminars every year.
