The　importance　and　urgency　of　improving　energy　and　carbon　emissions　efficiency　in　mitigating　climate　change　and　achieving　carbon　neutrality　have　become　an　increasingly　relentless　focus　in　recent　years.　Assessing　the　performance　of　energy　saving　and　carbon　emissions　reduction　is　a　significant　necessity　to　achieve　sustainable　economic　development.　Therefore,　from　the　perspective　of　production　economics,　this　paper　presents　a　review　of　the　definition,　models,　and　input-output　variables　for　measuring　total-factor　energy　efficiency　and　total-factor　carbon　emissions　efficiency.　Relevant　literature　in　this　field,　published　between　2006　and　2021,　has　been　systematically　analyzed　using　CiteSpace　software,　which　includes　a　quantitative　and　visual　review　of　a　large　body　of　published　literature.　This　review　found　that　the　current　definitions　of　total-factor　energy　efficiency　and　total-factor　carbon　emissions　efficiency　are　confusing　and　misleading.　Furthermore,　future　research　on　energy　saving　and　carbon　emissions　reduction　should　incorporate　subject　areas　such　as　economics,　energy,　and　ecology.
