摘要：

Based　on　the　theory　of　exergy,　combined　with　input-output　based　inventory　calculation　model,　the　cumulative　exergy　demand　(CExD)　of　energy　production　in　China　was　calculated.　The　CExD　of　different　energy　carriers　was　compared　and　the　proportion　of　exergy　consumed　in　high　tier　of　production　layers　in　CExD　was　analyzed.　The　results　show　that　for　1　MJ　of　different　energy,　electricity　has　the　largest　CExD　with　3.4　MJ,　followed　by　other　secondary　energy　with　1.55-1.63　MJ,　and　the　CExD　of　primary　fossil　energy　is　the　least　with　1.18-1.23　MJ.　The　results　also　show　that　input-output　based　inventory　calculation　model　is　more　appropriate　for　the　analysis　of　energy　system　than　process　based　model.
