A dense formal sentence. 創意になる ('of one's invention, devised by') is a formal collocation — 創意 ('original idea, ingenuity') + になる here marks the source. 行き詰まる ('to reach a dead end, stall') is a compound verb. 赤字 ('deficit, red figures') is idiomatic business vocabulary — losses historically recorded in red ink. The whole sentence reads like newspaper economic coverage.
