The key word is effective … It would be pointless to build more then one Trade Center for your Empire and this is worded to instruct new Players only to build ONE for their empire.

building more than one facility is effective if you need minerals. i have not checked the most recent Version as i have been on the road but from what i remember of Version 2.x the trade center generate a certain amount of resources each turn. so does the system mtce facility and one or two others. so in finite resource games or just ones where you need a few extra resources and you have the space then building these facilities would benefit you.
