Fully　analyzing　the　impact　and　role　of　digital　inclusive　finance　on　the　improvement　of　renewable　energy　efficiency　plays　an　important　role　in　realizing　the　long-term　sustainable　development　of　regional　economy.　This　research　undertakes　a　comprehensive　empirical　examination　to　investigate　the　influence　of　digital　inclusive　financial　growth　on　renewable　energy　efficiency　across　30　Chinese　provinces　and　cities,　spanning　from　2011　to　2021.　The　results　demonstrate　that　the　advancement　of　digital　inclusive　finance　significantly　improves　the　efficiency　of　renewable　energy.　The　examination　of　regional　variations　indicates　that　while　digital　financial　inclusion　markedly　enhances　the　efficiency　of　renewable　energy　in　both　eastern　and　western　areas,　its　impact　remains　negligible　in　the　central　region.　In　addition,　our　influencing　mechanism　results　show　that　the　progress　in　regional　science　and　technology,　alongside　the　effectiveness　of　financial　services,　markedly　boosts　the　beneficial　effects　of　digital　inclusive　finance　on　the　enhancement　of　renewable　energy　efficiency.　Furthermore,　the　degrees　of　innovation　in　science　and　technology　and　the　efficiency　of　financial　services　act　as　a　singular　threshold　in　the　development　of　digital　inclusive　finance　for　the　improvement　of　renewable　energy　efficiency.　Our　study　provides　new　evidence　and　implications　for　fully　realizing　the　combination　between　digital　inclusive　finance　and　renewable　energy　efficiency,　thereby　promoting　long-term　sustainable　regional　development.
