摘要	Input-output multiplier analysis converts the Leontief inverse into summary impact coefficients that answer how much total output, household income, or employment an economy generates per unit of final demand directed at a given sector. Building directly on Leontief's inter-industry accounting, it distinguishes the initial direct effect from the indirect supply-chain effect and, in the Type II form, the induced effect of household re-spending, yielding the multipliers that underpin most regional and project economic-impact studies.	Input-output analysis is a quantitative framework for representing the interdependence between the industries of an economy, introduced by Wassily Leontief in 1936. It records the flows of goods and services between sectors in a transactions table, derives fixed technical coefficients describing how much each industry buys from every other industry per unit of output, and inverts the resulting linear system to trace how an exogenous change in final demand ripples through the entire production structure.
