As　the　first　of　the　five　development　concepts,　innovation　can　effectively　drive　the　healthy　development　of　economy.　as　the　main　factor　influencing　regional　innovation,　the　regional　innovation　environment　can　to　some　extent　affect　the　regional　innovation　input　and　output,　which　has　far-reaching　significance　for　the　overall　innovation　development　and　even　economic　development　of　the　region.　In　this　paper,　the　main　factors　influencing　the　regional　innovation　environment　are　extracted　by　factor　analysis,　and　on　this　basis,　cluster　analysis　is　applied　to　analyze　the　innovation　environment　level　of　all　provinces　in　China.　Through　the　research,　we　found　that　the　regional　innovation　environment　in　China　was　quite　different　in　general,　among　which　the　eastern　region　was　significantly　better　than　the　central　and　western　regions.　further　classification　could　divide　the　regional　innovation　environment　into　three　categories.
