If you have constant shortages around the empire, while I don't. What are we doing/observing different?
I build my state ships mostly at the capital until other major colonies with large spaceports are present. Even after that, the capital receive the largest orders. I don't order 5 small spaceports at once in an empire just into space, and I see the ones I order built reasonably fast, the resources are delivered.
I get some noise about mines missing upgrade materials, and some stupid constructors missing something. That fixes itself reasonably fast.
If you have constant (real) shortages, you either have a shortage of materials, or you have a very difficult empire with significant distances between the parts. Do your state shopping at the capital, small buys elsewhere, and I think the orders placed over the order tool actually manages to distribute themselves pretty well. Try to get a feel for where you have resources and where you do not, the new signals on build buttons should help with that.
