In　this　paper,　the　improved　ecological　network　analysis　framework　is　applied　to　study　the　internal　metabolic　process　and　external　stability　of　the　urban　energy　metabolism　system.　Firstly,　based　on　the　analysis　of　ecological　network,　the　sectors　are　selected　from　the　three　stages　of　urban　energy　production,　transformation　and　consumption　to　build　an　ecological　network　model.　Then,　according　to　the　metabolic　process　and　stability　characteristics　of　urban　energy　system,　the　Network　Environ　Analysis　and　Ascendency　are　integrated,　and　the　time　dimension　is　expanded.　Finally,　the　data　of　Beijing　from　2007　to　2016　are　selected　for　empirical　study.　The　results　show　that:　(1)　the　cumulative　consumption　of　raw　coal　and　coal　products　and　natural　gas　has　changed　significantly,　the　former　has　decreased　from　3448　x　10(4)　tce　to　1283　x　10(4)　tce,　and　the　latter　has　increased　from　560　x　10(4)　tce　to　3699　x　10(4)　tce;　(2)　the　electricity,　heat　and　water　production　and　supply　sector　consumed　the　most　energy;　(3)　the　energy　transfer　pathways　between　sectors　has　changed　significantly.　The　results　of　stability　analysis　show　that　the　overall　stability　of　Beijing＇s　energy　metabolism　system　is　increasing　year　by　year,　but　there　is　still　space　for　further　improvement.　This　provides　an　important　reference　for　optimizing　the　energy　utilization　structure　of　Beijing　in　the　future　and　further　promoting　clean　energy　initiatives.
