摘　　要：以城市蔓延指数的测算为基础,利用中国213个地级及以上城市的面板数据,分析了城市蔓延对电力强度的影响效应。结果显示:总体上城市蔓延对电力强度具有显著的正向影响;电力强度随城市蔓延的扩散呈先递减后递增的U型特征,当城市蔓延指数为0.6左右时,电力能源效率最高;不同地区、不同规模城市的蔓延程度对电力强度的影响具有稳健性,但实际效应存在差异。In order to explore the relationship between urban sprawl and power intensity,this essay empirically analyses the influence of urban sprawl on power intensity using panel data of 213 cities from 2000 to 2015.Results show that:Urban sprawl has a significant positive influence on power intensity;Power intensity shows a U-shaped characteristic with the change of urban sprawl,and when the Urban Sprawl Index is about 0.6,the power energy efficiency is the highest;The influence of urban sprawl on power intensity is robust for cities of different regions and sizes,but the actual effects are different.
