べくIn order to (formal purpose)

How the sentence works

The verb before べく names the intended goal. The following clause then gives the action chosen as a means of reaching it. The relationship must be purposeful: someone decides to perform the later action because it can help achieve the earlier goal.

Institutional purpose

Both forms with suru

The full and shortened forms are both possible. The shorter form is especially compact and often fits official writing well.

Keep the actor clear

Normally, the same person or organization pursues the goal and carries out the action that follows. When several participants appear, state their roles clearly; otherwise readers may not know whose purpose the first clause expresses.

Formal versus everyday purpose

ために is the neutral choice for ordinary conversation and general-purpose writing. べく presents a similar deliberate purpose in a more compressed, official, strategic, or elevated style. Replacing the everyday form mechanically can make a simple personal remark sound needlessly grand.
