The households' relationship in terms of house buying and fertility behavior has received much attention due to the high housing prices and low birth rate in Taiwan. These two behaviors are households' major expenses and there might be resource exclusion. However, previous studies have ignored that the contribution of these two behaviors regarding improving households' stability may encourage them to have children or buy houses. Thus, this study has tried to investigate the relationship of these two behaviors from the dimensions of resource exclusion and motivated stimulus by constructing the survival models. The empirical data were retrieved from the Panel Study of Family Dynamics (PSFD) in Taiwan. The results show that the probability of first-time house buying increases with a gradual decrease after the household's birth of the first child. On the other hand, the probability of fertility decreases gradually over time after the household's first-time house buying. It indicates that the effects of resource exclusion and motivated stimulus change over time and there exist different effects in terms of the order of house buying and fertility behaviors. The force is also different when the events occur in a period of high prices.
