摘　　要：本文根据2014-2018年全国336个地级市的城镇常住人口统计数据,采用城市金字塔理论、城市首位律及城市位序-规模法则,从全国、省域两个尺度考察中国城市规模时空差异。结果表明:①我国超大城市数量无明显变化,特大城市数量增多,小城市数量减少,且大、中城市多分布于“胡焕庸线”以东;②我国城市首位度下降,27个省域城市首位度变化趋势不同;③城镇人口数量、第二、三产业生产总值均符合位序-规模法则。According to the statistics of resident population in 336 prefectural-level cities in China from 2014 to 2018,we adopted the urban pyramid theory,the law of primate city and the rank-size rule to investigate the spatial-temporal differences of cities'size from national and provincial scales.Our results revealed that:①The number of megacities had no significant change while extra-large cities were increased.Conversely,small cities were countered with the former one.From spatial aspect,medium-sized cities were mostly distributed in the east of"HuHuanyong line";②The influences of primate cities were decreasing,and the varying trends of S2&S4 in 27 provinces were diverse;③Residential population and GDP of the secondary and tertiary industries conformed to the rank-size rule.
