Grammar
-(으)ㄹ 것으로 전망하다
Meaning
Expert-(eu)l geoseuro jeonmanghada
전망(展望) is an outlook — how someone thinks things will go over a coming period. The clause being forecast is nominalised with -(으)ㄹ 것 and marked with 으로, and 전망하다 is active, so the forecast belongs to a subject: an institute, a central bank, a panel of experts. That is the whole point of choosing the active verb over its passive twin 전망되다 — the sentence tells you a forecast was issued and by whom, which is what lets a reader judge it. When the surrounding sentences have already named the forecaster, Korean simply leaves the subject out, as in 수출은 8.7% 늘어날 것으로 전망했습니다, but the active ending still says that someone did the forecasting.
Form
Verb stem + -(으)ㄹ 것으로 전망하다: -ㄹ 것으로 after a vowel-final stem (늘어나다 → 늘어날 것으로), -을 것으로 after a consonant-final stem (넘다 → 넘을 것으로), with a stem-final ㄹ dropped (늘다 → 늘 것으로). News keeps the verb in the past — 전망했다, 전망했습니다 — because a forecast is published on a date. The forecaster is the sentence subject; what is forecast carries 은/는 or 이/가 inside the embedded clause (수출은 … 늘어날 것으로). A passive 전망되다 (전망된다, 전망됐습니다) exists and is used when no forecaster is being named.
Examples
수출은 8.7% 늘어날 것으로 전망했습니다.
It forecast that exports would grow 8.7 percent.

Common mistakes & nuance
전망하다 looks forward only. It cannot report something already settled, and it cannot report what a survey found — that is -(으)ㄴ 것으로 나타나다, where the modifier is -(으)ㄴ rather than -(으)ㄹ. Against 예상하다, 전망 is the more institutional word, at home with growth rates, trade balances and traffic over a season, while 예상 covers ordinary expectation of any size. The bigger thing to hold on to is voice: 전망하다 and 추산하다 keep the forecaster in the sentence, whereas 예상되다, 기대되다, 나타나다 and 확인되다 remove them. Reading news, that is the difference between a claim you can attribute and one you cannot.
Similar grammar
- -(으)ㄹ 것으로 예상되다
The passive twin of this pattern. 예상되다 hides who is doing the expecting and presents the forecast as if it were in the air; 전망하다 keeps the forecaster as the subject. 전망 also leans institutional, while 예상 is the plainer everyday word.
- -(으)ㄹ 것으로 추산하다
Both are active and name whoever made the call. 추산하다 puts out a number computed from incomplete data, so it is unnatural without a figure; 전망하다 puts out an outlook, which can be purely directional.
