Calculation

The process of calculation is done in 4 steps:

- Step 1: Calculating Inventory index of each commodity

Formula:

q
i = Kn 1  100
Kn
q Kn 0

Where:

iKn: Inventory index of commodity n;

qKn1: Quantity of Inventory commodity n at reference time;

qKn0: Quantity of Inventory commodity n at base time.

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

Formula:

i h
I KN 4 =  Kn Kn
h
 Kn
Where:

IKn4: Inventory index of VSIC 4-digit industry;

th
IKn: Inventory index of commodity n in VSIC 4-digit industries;
hKn: Weight of commodity n.

Weight of commodity is the value of average inventory of

commodity at base year of 2010 (average of the beginning and the end
of 2010).

- Step 3: Calculating inventory index of VSIC 2-digit industries

Formula:

I h
I KN 2 =  KN 4 KN 4
h
 KN 4
