תקציר	Structural decomposition analysis (SDA) explains how an input-output quantity — total output, value added, energy use, or emissions — changed between two periods by attributing the change to its underlying structural determinants, chiefly shifts in production technology (the Leontief inverse) versus shifts in the level and composition of final demand. Built on comparative statics over two or more comparable tables, SDA expresses the difference as a sum of effects and resolves the indeterminacy of multiplicative terms by averaging the two polar decomposition forms, the convention standardized by Dietzenbacher and Los.	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.
