摘要	Poverty Dynamics Analysis uses household panel data to study how poverty changes over time for the same people, distinguishing those who are persistently poor from those who move in and out of poverty. Building on the work of Jyotsna Jalan and Martin Ravallion (1998) and the comparative synthesis of Bob Baulch and John Hoddinott (2000), it reframes poverty from a static headcount into a study of entries, exits, and spells. Its central output is a separation of total poverty into a chronic component, attributable to persistently low living standards, and a transient component, attributable to fluctuations around the poverty line over time.	A household livelihood survey is an instrument designed to capture the full portfolio of activities, income sources, assets, and expenditures through which a household secures its living. Rooted in the rural-livelihoods literature associated with Frank Ellis and in global comparative income studies such as the CIFOR Poverty Environment Network, it measures welfare and resilience by mapping the diversity of a household's economic activities — farming, wage labour, self-employment, environmental harvesting, transfers, and remittances — rather than reducing the household to a single income or consumption figure.
