The　rapid　social　and　economic　development　has　led　to　problems　such　as　over-exploitation　of　water　resources,　strong　demand　for　physical　water　resources,　and　disequilibrium　of　water　resources　load.　Based　on　the　current　situation　of　the　water　resources　system　in　Beijing-Tianjin-Hebei　region,　this　study　proposed　an　input-output　analysis-assessment-prediction-optimization　framework.　A　water　resources　dissipation　environment　extended　multi-regional　input-output　model　was　established,　and　the　spatial　equilibrium　of　water　resources　load　was　evaluated　comprehensively.　Furthermore,　a　multi-dimensional　spatial　equilibrium　optimal　allocation　for　water　resources　was　built　to　identify　key　nodes　and　sectors.　The　primary　findings　were　as　follows:　(1)　Shijiazhuang　and　Tangshan　were　the　main　cities　with　net　virtual　water　outflow,　while　Beijing　and　Baoding　were　the　primary　recipients　of　net　virtual　water　inflow;　(2)　The　overall　score　for　the　spatial　equilibrium　assessment　of　water　resource　load　was　low,　with　dimension　scores　predominantly　ranging　between　0.2　and　0.6;　(3)　The　key　transfer　nodes　were　predominantly　concentrated　on　the　＂outflow　from　Shijiazhuang＂　and　the　＂inflow　to　Cangzhou　and　Langfang＂　nodes.　This　research　conducted　an　in-depth　exploration　of　the　direction　of　water　resource　transfers,　the　actual　stress　conditions,　and　the　spatial　equilibrium　of　water　resources　within　the　Beijing-Tianjin-Hebei　region.　Finally,　the　future　adjustment　strategy　for　water-intensive　industries　at　the　urban　agglomeration　scale　was　obtained.
