The　imbalance　of　regional　development　is　an　important　problem　in　China＇s　economic　development.　This　paper　measures　the　allocation　efficiency　of　financial　resources　of　31　provinces　in　China　from　2008　to　2018.　This　paper　makes　up　for　the　deficiency　of　the　traditional　DEA　model　in　variable　selection　and　efficiency　identification.　Firstly,　we　use　AIC,　BIC,　and　HQC　information　criteria　to　select　variables,　and　construct　a　more　scientific　and　reasonable　financial　efficiency　evaluation　index　system.　On　this　basis,　the　Shannon　entropy　index　is　used　to　improve　the　discrimination　ability.　The　results　show　that:　(1)　The　combination　of　Shannon　entropy　index　makes　the　result　more　accurate　and　improves　the　discrimination　ability.　(2)　The　Eastern　region　has　the　highest　CES　score,　followed　by　the　Midland　and　Western　region,　and　the　Northeast　region　has　the　lowest　CES　score.　(3)　Overall,　from　2008　to　2018,　the　efficiency　of　financial　resource　allocation　in　China　showed　an　upward　trend.　(C)　2021　The　Authors.　Published　by　Elsevier　B.V.
