The important effects of kinship on marital relationships have long been examined in depth and thoroughly documented by sociologists; but little evidence has been reported in the literature on economics. This study explores the kinship-related factors that influence the stability of marriage, with a particular focus on the unique characteristics and long-standing traditions of Chinese society. One important finding is that women's traditional functions and kinship network are the main determinants of the marriage outcome of older couples, whereas preconceived notions of family and kinship play a significant role in the success or failure of marriage for younger couples.
