助力 literally means 'to assist with strength' — 助 (zhù) means 'to help, to aid', and 力 (lì) means 'strength, power, force'. Together, 助力 functions as a noun meaning 'assistance' or 'support', especially when that support actively contributes to progress, success, or improvement. It often carries a positive, dynamic connotation — like giving a helpful push or providing crucial backing.

This word is widely used in formal and semi-formal contexts: policy announcements, corporate communications, health campaigns, education initiatives, and technological development. While it can be used as a verb (e.g., 助力经济发展), it most commonly appears as a noun (e.g., 政策助力, 科技助力). It’s rarely used in casual daily speech among friends — more common in written reports, news headlines, or official speeches where emphasis is placed on collaborative or enabling support.
