Meaning
理论上 is an adverbial phrase meaning 'theoretically' or 'in theory.' It's used to contrast theoretical possibilities with practical reality, often implying that while something should work in principle, it may not work out that way in practice. The phrase combines 理论 (theory) with the locative particle 上 (on/in), literally meaning 'on the theory level.'
Usage
Commonly used in academic, scientific, and everyday discussions to acknowledge that something is possible according to theory but may face practical obstacles. Often paired with 但是 or 可是 to introduce the practical reality that differs from theory. Native speakers frequently use this phrase when explaining why ideal solutions don't always work in real life.
