The　National　High-tech　Zone　is　an　important　driving　force　for　the　transformation　and　upgrading　of　the　industrial　structure　and　it　is　also　an　important　guarantee　for　the　realization　of　an　innovation-driven　China.　Thirteen　indexes　are　selected　from　three　aspects　of　innovation　investment,　innovation　performance　and　innovation　support　to　construct　a　comprehensive　evaluation　index　system　of　innovation　capability　of　national　high-tech　zones　in　the　northern　coastal　comprehensive　economic　zone.　On　this　basis,　the　entropy　weight-fuzzy　comprehensive　evaluation　model　is　used　to　evaluate　the　innovation　and　develop-ment　capability　of　19　national　high-tech　zones　from　2015　to　2017　comprehensively.　The　results　show　that　the　comprehensive　index　of　innovation　capability　of　national　high-tech　zones　shows　an　upward　trend,　but　the　overall　innovation　capability　is　relatively　low;　The　contribution　of　each　subsystem　to　innovation　capability　is　different,　the　innovation　environment　is　the　largest,　the　innovation　performance　is　the　second,　and　the　innovation　investment　is　the　smallest;　According　to　the　level　of　innovation　ability,　19　high-tech　zones　are　divided　into　star　type,　moderate　type　and　backward　type,　with　moderate　type　high-tech　zones　accounting　for　the　largest　proportion.
