When to use it

Says that a result depends largely on a particular cause, "largely due to" or "owes much to." It is a balanced way to give credit or explain a cause without saying it is the only one. Example: 成功せいこうはチームワークによるところが大おおきい (the success was largely due to teamwork).

Nuance

Formal, typical of reports, news, speeches and academic writing. It is neutral in tone and can describe good or bad results. It analyzes causes; it is not used for the speaker's own plans or intentions. The past form 大おおきかった is common for finished events.

Compare

のおかげで thanks a cause and is more personal: 先生せんせいのおかげで合格ごうかくした. によるところが大おおきい sounds analytical and modest. に負おうところが大おおきい is nearly the same but stresses indebtedness. によって states a cause or means plainly, without "largely."

Tip: ところ here means "the part": "the part that comes from X is big." That is why it means "largely due to."
