[Grammar] A driver of vs the driver for

[holdenenglish]

Hi teachers

I've written the following two sentences. Should I use a driver OF, or a driver FOR, and why? And, is it grammatical to use "the driver" if I start the second sentence with "for investors"?

1. Asia is expected to be a driver of global growth in the coming decades.
2. For investors, Asia will be the driver for global growth in the coming decades.

Cheers

Holden

A driver is one of many. The driver is the only one. (Or only significant one.)

I prefer "of."

If you use "a", you would be implying that Asia will be one of several drivers. If you use "the", you'd be implying it will be the only/main driver.
I prefer "driver of growth" to "driver for growth".
