<p>Concerns about intergenerational residence patterns and intergenerational support have been central to the practice of filial piety, but little is known about how changes in intergenerational residence affect different types of intergenerational support. This study investigates how different types of support provided by children (upstream support) change when the type of intergenerational residence shifts from coresidence to noncoresidence and from noncoresidence to coresidence in the context of filial piety. Data were taken from the 2002–2018 waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Pooled regression was used to estimate the effect of dynamic changes in intergenerational residence on upstream support. The results revealed that when intergenerational residence changed from noncoresidence to coresidence, the instrumental care provided for elderly parents increased significantly; however, when intergenerational residence changed from coresidence to noncoresidence, the opposite was true. The results suggested that after adjusting for inflation, parents who transitioned to noncoresidence received approximately 35% more financial support than those who remained coresident; however, transitioning to coresidence had a smaller and weaker impact on financial transfers. Taken together, these findings suggest that children practice filial piety differently depending on changes in intergenerational residence patterns.</p>
