[Objective] The economic, environmental, and social benefits of rainwater utilization at urban sponge community were evaluated and the cost comparative analysis were conducted in order to establish a reference for the evaluation of the construction of a sponge community.[Methods] The second batch of six sponge communities was obtained as the research object; this was sourced from the Southwest New District of Guyuan City in Ningxia Hui Autonomous Region. The water balance method, alternative engineering method, shadow engineering method, market value method, carbon tax method and afforestation cost method were used to generate the sponge community. The rainwater resource utilization, carbon sequestration, oxygen reduction, noise reduction, storage runoff, culture and education, etc, the ten benefits in three categories were quantitatively calculated. Further, the cost-benefit ratio was used for the static and dynamic cost-benefit analysis.[Results] The total benefit of the six sponge communities in the southwest of the New District of Guyuan City was 2.91×10⁵ yuan/year. Moreover, the benefits of the rain garden, sinking green land, and planting grass were 1.03×10⁵, 7.99×10⁴, and 6.15×10⁴ yuan/year, respectively. The economic, environmental and social benefits accounted for 22.84%, 76.89%, and 0.27%, respectively.[Conclusion] Therefore, the use of rainwater in the sponge community has noteworthy investment benefits. Accordingly, the construction of the sponge community in Guyuan City has produced good economic, environmental, and social benefits, which deserves further research and promotion.
