Abstract: Objectives To investigate the construction and management mode of volunteer donor team in Chengdu-Chongqing Economic Circle, and propose improvement strategies to provide data for optimizing donor service management. Methods A total of 1 000 volunteers, 500 from Chongqing and 500 from Chengdu, were enrolled from January to June 2024. Data were collected using a questionnaire survey. The questionnaire included two parts: basic information and a rating scale. The latter used a Likert scale to score behavior patterns, subjective awareness, service motivation, life happiness, and intention for continued service. Data analysis were performed using SPSS version 26.0, including descriptive statistics, factor analysis, linear regression analysis, and model fit assessment. Results The result showed that the young (aged 18~25) , with high education (such as bachelor's degree or above) and high-income (monthly incomes of 8 001 yuan or more) groups had significantly higher scores in the service motivation (scores 3.38, 3.40, and 3.47, P<0.05, respectively) and life happiness (3.53, 3.57, and 3.63, P<0.05, respectively). Chengdu volunteers were significantly higher than Chongqing volunteers in terms of subjective awareness (3.59, P<0.01), service motivation (3.35, P<0.01) and intention for continued service (3.57, P<0.05) (3.51, 3.28, 3.39, respectively). The linear regression analysis showed that life happiness (partial regression coefficient=0.214, P<0.001), service motivation (0.200, P<0.001), subjective awareness (0.117, P=0.013), and behavior patterns (0.130, P=0.019) had a significant positive influence on the intention for continued service. The model fit assessment showed that the model had good fit, fit indices: chi-square ratio by degrees of freedom (χ²/df)=1.844, goodness-of-fit index (GFI)=0.933, root mean square error of approximation (RMSEA)=0.006, comparative fit index (CFI)=0.919, normed fit index (NFI)=0.958, and non-normed fit index (NNFI)=0.942. All of them meet the goodness of fit criteria. Conclusion The study revealed the key factors affecting the behavior and attitude of volunteers, and found differences in volunteer service between Chengdu and Chongqing. It is suggested that measures such as enhancing social responsibility, optimizing recruitment and training strategies, enhancing service motivation and subjective awareness, focusing on life happiness, establishing incentive mechanism and strengthening regional cooperation, should be taken to promote the high-quality development of volunteer service in Chengdu-Chongqing Economic Circle.
