Based on the ecological footprint analysis method for water resources, the ecological footprint of water resources per 10 000 yuan GDP and the carrying index are calculated. The ecological footprint and carrying capacity of water resources as well as the relevant influence factors for the ecological footprint of water resources in Liaoning Province from 2006 to 2014 are analyzed. The features and influence degrees of various influence factors on the ecological footprint of water resources are investigated from the perspective of 63 counties in Liaoning Province. The results show that during the most years in the study period, the ecological carrying capacity of water resources is less than the ecological footprint of water resources. The ecological footprint of water resources per 10 000 yuan GDP decreases year by year. The development and utilization level has reached a very high degree. The effects of economic development and population growth push the growth of ecological footprint of water resources, while those of water footprint technology and water footprint structure suppress the growth of ecological footprint of water resources. The combined effects of various factors make the ecological footprint of water resources exhibit fluctuant decreasing trend. The effects of water footprint technology suppress the growth of the ecological footprint of water resources in all the counties in Liaoning Province, the effects of economic development push the growth the ecological footprint of water resources, and those of water footprint structure and population growth have different functions in different counties.
