Aiming at the uncertainty of decision-making factors and the difficulty of quantifying various subjective and objective weights in the process of rural pension service quality evaluation, this paper proposes a rural pension service quality evaluation method combining improved interval AHP and CRITIC method based on indicator correlation at the level of rural revitalization strategy. The method is based on 5 guidelines and 11 common factors, comprehensively considers the influence of subjective and objective weights on the design scheme, introduces the interval number and triangular fuzzy number, and establishes the evaluation index system of rural elderly service. By utilizing the improved interval AHP and CRITIC method, the subjective and objective weights of each evaluation index can be calculated. The analysis is done by combining examples to explore the ecological niche of the senior care industry, the rural suitability for elderly people, and their expectations and perceptions of the service. From the market ecological niche, it can be seen that the result of the senior care manufacturing industry measure is 0.85, which contributes the most to the rural economy in rural revitalization. The travel, ecological landscape, living services, and socio-economic environment in rural areas are improved under the rural revitalization strategy, and the weighted scores of the four are 0.5528, 1.1524, 1.299, and 0.6031, respectively. According to the comprehensive results, the rural revitalization strategy has resulted in a noticeable increase in the rural aged-care industry and services.
