This paper uses water footprint theory and provincial panel data 2004 to 2018 to evaluate the water resource benefits of Yangtze river economic zone, and applies spatial quantitative model to study the non\|linear impacts and spatial overflow of population, industries and economic urbanization on water resource benefits, with the results showing a rising economic efficiency and contributing rate of water resource in Yangtze river economic zone along with an increasing water resource pressure. Urbanization and water resource benefits show an outstanding spatial concentration. Industries and economic urbanization have a “U\|shaped” relation to economic efficiency of water resource, but an upside\|down “U\|shaped” relation to water resource pressure. Population urbanization acts in a reverse way. Population and industrial urbanization produce an apparent spatial overflow effect on water resource benefits with a threshold. Industrial and economic urbanization has broken through the threshold effect in Yangtze river economic zone, only leaving threshold in partially west for population urbanization.
