We　examine　the　impact　of　human　capital　on　innovation　investment　persistence　using　a　sample　of　high-tech　companies　listed　in　the　Chinese　A-share　market　for　the　period　2009-2017.　We　find　that　human　capital　mitigates　the　negative　effect　of　financial　constraints　on　innovation　investment　persistence.　We　further　explore　the　mechanism　through　which　human　capital　at　the　management　and　employee　levels　affects　innovation　investment　persistence.　We　find　that　management　human　capital　affects　innovation　investment　persistence　through　the　expectation　of　authorised　patents,　while　employee　human　capital　affects　the　persistence　through　salary　stickiness.　Furthermore,　we　find　that　management　human　capital　contributes　to　an　increase　in　future　granted　patents　through　persistent　innovation　investment.
