Starbase Stacking

Do starbase bonuses stack?

If I put two or three econ starbases up so that they all effect the same set of planets, do the planets (trade routes too?) get multiple bonuses, or just the best one?

I believe they get the multiple bonuses. However, the bonuses are additive, so if you had +100% from 4 starbases, you wouldn't double production 4 times to a total of 16x, you'd add 400% to get a total of 5x. Influence worked differently in GC1 and I haven't worked out if it still works the same in GC2, however. Stacking influence starbases can be really nasty, the GC1 term for it was a culture bomb.

Yes they do stack. I often build two econ bases next to my best planets. Assuming I can afford to do that.
