The structure 一方面…另一方面…
"On the one hand..., on the other hand…"
The parenthetical structure 一方面…另一方面… 
is used the same as in English. We use this structure when we talk about various aspects (mostly opposed to each other) of a situation.
For example: “On the one hand, renting a whole apartment is more expensive than just a room. On the other hand, you don't have to share a kitchen and a bathroom with someone else”.
