Abstract: An index system was constructed, and the comprehensive evaluation method and empirical data were used to calculate the realization degree of well-off society, and the Holt-Winter non-seasonal model was used for prediction. It turns out that China can achieve the goal of building a well-off society in an all-round way in 2020, but the degree of achievement of the indicators shows an uneven situation. The indicators of quality of life and economic development were over-fulfilled, and the degree of social harmony, democracy, legal system, culture and education, resources and environment were not satisfactory. There were significant short-board indicators in the secondary indicators, and there were large urban-rural differences in the degree of realization. Therefore, to build a well-off society in an all-round way, it is suggested to handle the relationship between growth and development, focus on breaking through the short-board indicators, and implement the strategy of rural rejuvenation and regional development to achieve a higher-quality, well-off society.

Key words: build a well-off society in an all-round way, Holt-Winter non-seasonal model, comprehensive evaluation method
