Hello peyzf,

I believe you are right.
The business continuity is the primary function of inventory.
The by-product of the manufacturing is also obvious,

Business owner needs to invest in raw material and direct labor, so that inventory could produce.
When the tax payer does this, he/she normally boosts up GDP.
In real life, GDP could also bump up even without meaningful production or service.

If you are more interested in the growth rate of GDP.
That will be a little bit complex.
One thing for sure, accumulated inventory may or may not improve the growth rate of GDP in the long run.
When you're talking about in the short period of time,
of course, you could always find various ways to get what you want.
The issue here is,
Is that meaningful?
Thanks.

pretty good , thanks~
