IIP is the ratio between quantity of industrial production at

current and base time.

The calculation of IIP begins with the calculation of production
index of commodity. From production index of commodity,
production indexes of VSIC 4-digit industries, VSIC 2-digit
industries, VSIC 1-digit industries and the whole industry can be

calculated and so is IIP for a province or the whole country.

Calculation:
- Step 1: Calculating production index of commodity

Formula:
q
i qn = 1 n  100
q n 0

Where:

iqn: Production index of commodity n (For example: electricity,
coal, fabric, cement…);

qn1: Quantity of commodity n at reference time;

qn0: Quantity of commodity n at base time.

- Step 2: Calculating production index of VSIC 4-digit
industries

The production index of VSIC 4-digit industries is the weighted

average index of representing commodities for VSIC 4-digit
industries.

Formula:

i  W qn
 qn
I qN 4 =
 W qn

Where:

IqN4: Production index of VSIC 4-digit industry N;
