The　share　of　electricity　consumption　by　urban　and　rural　residents　in　China’s　overall　electricity　consumption　is　very　close　to　that　of　the　tertiary　sector,　which　has　become　an　important　driver　of　China’s　electricity　consumption　growth.　At　the　same　time,　due　to　the　mismatch　between　China’s　regional　resource　endowments　and　the　level　of　regional　development,　the　regional　supply　and　demand　situation　for　electricity　varies.　Therefore,　it　is　urgent　to　clarify　the　regional　differences　in　residential　electricity　consumption　and　the　factors　affecting　it,　and　accordingly　adopt　targeted　and　feasible　measures　to　regulate　residential　electricity　consumption.　This　article　includes　data　from　285　Chinese　prefecture-level　cities　from　2006　to　2019,　and　adopts　a　“three　lines”　method　of　region-partitioning　(Qinling–Huaihe　line,　Huhuanyong　line,　and　Shanhaiguan　line)　to　divide　four　regions.　We　used　spatial　econometric　models　to　examine　residential　electricity　consumption　and　its　influencing　factors　in　China　from　the　standpoint　of　regional　heterogeneity.　The　results　show　that　there　is　significant　regional　heterogeneity　in　residential　electricity　consumption　in　China,　and　the　difference　between　the　north　of　the　Shanhaiguan　line　and　other　areas　is　significant.　Moreover,　there　is　a　positive　spatial　correlation　in　the　per　capita　domestic　electricity　consumption　of　urban　residents,　and　each　influencing　factor　has　obvious　regional　heterogeneity,　among　which　household　appliances　are　the　significant　influencing　factor.　Based　on　the　regional　heterogeneity　of　residential　electricity　consumption,　management　measures　should　be　formulated　according　to　local　conditions,　and　the　supply　of　electricity　should　be　ensured　by　strengthening　multidimensional　initiatives.　©　2023　by　the　authors.
