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

The production index of VSIC 2-digit industries is the weighted
average index of representing VSIC 4-digit industries in VSIC 2-digit
industries.

Formula:

I
I qN 2   qN 4  W qN 4

W
qN
4
Where:
I qN2 : Production index of VSIC 2-digit industries;

I qN4 : Production index of VSIC 4-digit industries;

W qN4 : Weight of VSIC 4-digit industries. Weight of VSIC 4-digit

industries is the value added at current price in 2010.

- Step 4: Calculating production index of VSIC 1-digit industries

The production index of VSIC 1-digit industries is the weighted
average index of representing VSIC 2-digit industries in VSIC 1-digit
industries.

Formula:

I 2  W qN 2
 qN
I qN 1   W qN 2

Where:

I qN1 : Production index of VSIC 1-digit industries;

I qN2 : Production index of VSIC 2-digit industries;

W qN2 : Weight of VSIC 2-digit industries. Weight of VSIC 2-digit
industries is the value added at current price in 2010.
