To study the coordination of water resources utilization and economic growth, a calculating method of water ecological footprint was put forward by considering different receptive water bodies. This method was used to calculate water yield and ecological footprint of water quality of Shandong Province in 2003—2015. Macro-level coordinated development of decoupling evaluation model and micro-level coordination degree theory were established to evaluate the coordination relationship between water resources consumption and economic growth. The results found that the water ecological footprint of Shandong Province presented an uptrend of fluctuation overall, and the ecological footprint of water showed obvious agricultural dominance. The proportion of ecological footprint of surface water to groundwater was 3∶4, and in the ecological footprint of surface water, nitrate nitrogen was the deci-sive pollutant in 2003—2009, but phosphorus was the decisive pollutant in 2010—2015. The ecological footprint of groundwater was more complicated, which was alternately determined by COD, nitrate nitrogen and phosphorus. The per capita GDP growth and water ecological footprint are transformed from the primary coordination of weak decoupling to the intermediate coordination of strong decoupling. It is basically suggested that the coordinated development of water resources and economy in Shandong Province shows an improved trend.
