To evaluate the influences of home-based elder care services on the quality of life for the elderly, the paper constructs related indexes and analyzes the data from CLASS with Propensity Score Matching Method. Conclusions: (1) Home-based elder care services can improve the quality of life for the elderly. The standard score of the Average effect of the Treatment on the Treated (ATT) is 0.315, but the score of those in rural areas is 5.5 times larger than that in urban areas. (2) ATT is rising, but the intervention effects diverge between rural and urban areas with an increasing trend in rural areas and a decreasing trend in urban areas. (3) An evaluation method for the intervention effects has been explored. Suggestions: We shall improve the quality of the home-based elder care services, and explore factors that affect the quality of life for the elderly. We can perfect relevant development paths and evaluation systems, and improve the intervention effects by promoting the fairness of service utilization.
