Abstract: The perception of social fairness is an individual's overall perception or judgment of the state of social equity. Based on the repeated cross-sectional data of the China General Social Survey from 2010 to 2018, this study provides a holistic analysis of the shifting trends of social fairness perception and their explanatory factors during the two major transition periods of China, namely, the past transition period of reform and opening up and the current transition period of diversified development. With the help of mathematical models such as log-linear models and multilevel age-period-cohort models, the following three major findings are observed. First, in the current transition period, the total social mobility rate and the upward mobility ratio have been rising, and people's perceptions on social equity show a upward trend of volatility; while in the historical transition period, with the establishment and continuous improvement of markets, the perceptions of fairness experienced a rapid decline, and then a rapid improvement. Second, the three factors of social structure, social psychology and cultural norms are neither mutually exclusive nor competitive in the changing process of social equity perceptions, but are intertwined and function in different ways. Among them, social structural factors such as intergenerational mobility are foundational to the changes in the perception of social equity, while subjective class mobility perceptions are the direct source of people's perceptions and cultural norms constitute a stable potential factor. Third, this study examines the status of social equity from the perspective of social stratification and mobility, and takes the occurrence of intergenerational mobility, and its direction and distance as key indicators to measure the objective equity status. It is found that social equity status and the sense of fairness are linked, but the moral concept on which the perception of fairness is based has changed with the transformation of society in specific historical periods. This study extends the research on social equity perceptions to the macro-process and dynamic analysis of social structural transformation and people's mentality transformation. It overcomes the relatively crude measurement of intergenerational mobility distance as well as the treatment of social equity perceptions as a static factor in previous studies. In this regard, it offers an important direction for future research to investigate deeper into the tension between subjective and objective equity and explore a new model of social stratification.
