This　study　focuses　on　improving　financial　efficiency　and　rationally　allocating　financial　resources　in　the　Beijing-Tianjin-Hebei,　based　on　data　from　2011　to　2019.　Firstly,　the　Slack-Based　Measure　(SBM)　model　based　on　Shannon　Entropy　is　adopted　to　measure　financial　efficiency　in　Beijing-Tianjin-Hebei.　Secondly,　a　Beijing-Tianjin-Hebei　inter-regional　financial　resource　allocation　scheme　is　proposed　using　the　Generalized　Equilibrium　Efficient　Frontier　Data　Envelopment　Analysis　(GEEFDEA)　model.　Finally,　the　external　environmental　factors　influencing　financial　efficiency　are　explored　using　spatial　and　other　econometric　models.　Efficiency　measurement　reveals　that　financial　efficiency　in　Beijing-Tianjin-Hebei　is　unevenly　developed.　The　financial　efficiency　of　Beijing,　Tianjin,　and　Zhangjiakou　is　high　and　stable,　whereas　the　financial　efficiency　of　Tangshan,　Langfang,　and　Shijiazhuang　is　high,　but　fluctuates　significantly.　In　comparison,　the　financial　efficiency　of　other　cities　is　low.　The　factors　and　the　adjustment　amount　to　improve　urban　financial　efficiency　are　obtained　by　studying　the　allocation　of　financial　resources.　And　it　is　found　that　Tianjin　and　Tangshan　have　more　financial　resource　surpluses　than　other　cities.　By　exploring　influencing　factors,　it　is　found　that　the　financial　development　level,　innovation　level,　and　infrastructure　construction　level　of　Beijing-Tianjin-Hebei　significantly　affect　financial　efficiency.
