With the cohort replacement and rapid growth of older population, the young older adults have become the main force driving older adults' consumption, gaining growing importance in overall residential consumption. Based on data from the 2018 China Health and Retirement Longitudinal Study (CHARLS), this study empirically examines the impact of social activities on the consumption of the young older adults. Results show that the diversity of social activities and the frequency of social participation significantly increase consumption levels, and contribute to the upgrading of consumption patterns. The participation in social activities of the young older adults weakens the negative effect of early family economic disadvantages on consumption levels. Furthermore, the effects of social activities are more pronounced in increasing the consumption levels of the young older adults who are in areas with a higher inclination toward cultural services. In light of these findings, the study advocates for increased investment in public cultural services, establishment of diverse social platforms, and encouragement of the young older adults to engage in diverse and frequent social activities. Simultaneously, it is important to regulate the development of industries catering to older adults to diversify their consumption patterns and unlock their consumption potentials.

Clan culture, based on blood and kinship, is a major cultural feature of Chinese vernacular society. Clan culture not only has far-reaching effects at origin, but also continues to affect behavioral decision-making among migrants at destination. Based on the 2017 China Migrants Dynamic Survey (CMDS2017) data, the Probit model regression shows that the clan culture at origin significantly promotes migrants to make entrepreneurial choices. The mechanism analysis shows that clan culture has an impact on migrants' entrepreneurial choices through the formation of a hometown social network and social trust. Further research finds that clan culture promotes the choice of survival-oriented entrepreneurship among migrants, but is detrimental to the entrepreneurial effect of opportunity-oriented entrepreneurs, and that the urban formal system can replace the influence of clan culture on entrepreneurship. The policy implication of this study is that efforts should be made to use the hometown network social organization platform, build a general trust culture that goes beyond intra-clan trust, as well as actively explore the establishment of traditional Chinese culture and formal system complementary role mechanisms to help migrants start businesses and achieve entrepreneurial effects in the cities.
