This　study　uses　the　spatial　panel　model　to　explore　the　cross-agency　spillover　effects　of　bank　internal　regulation　on　systemic　risk　and　the　moderating　effect　of　bank　FinTech　in　the　relationship　between　them.　We　construct　spatial　weight　matrices　for　asset　and　liability　homogenisation　to　capture　the　channels　of　systemic　risk　transmission　in　banks.　The　text　analysis　approach　is　used　to　measure　the　internal　regulation　of　the　bank　and　the　FinTech　level.　Empirical　results　demonstrate　that　the　local　bank＇s　internal　regulation　can　significantly　reduce　its　own　systemic　risk.　The　neighbouring　banks＇　internal　regulation　can　significantly　reduce　the　systemic　risk　of　the　local　bank.　As　the　bank　FinTech　level　increases,　the　role　of　bank　internal　regulation　in　reducing　systemic　risk　will　gradually　decline.　Additionally,　both　asset　and　liability　homogenisation　are　potential　channels　for　systemic　risk　spillover.
