Industrial product is an indicator reflecting the direct results generated
by industrial production in a given period including industrial physical products
and services.

Industrial physical products are industrial products generated by using
working instruments acting upon object to turn the original mode of materials
into new products with new utilization value or products explored from mines.
Industrial physical products include: (1) Finished products are industrial
products manufactured conformable with specifications and technical standards;
(2) Secondary products are industrial products still having utilization value and
