| Összefoglaló≠ | 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. | Environmentally extended input-output (EEIO) analysis appends satellite accounts of physical environmental flows — greenhouse-gas emissions, energy, water, land, and materials — to a monetary input-output table so that environmental burdens can be allocated through supply chains to the final demand that ultimately drives them. By multiplying direct environmental-intensity coefficients by the Leontief inverse, EEIO computes the total burden embodied in each unit of final demand, providing the standard framework for consumption-based carbon footprints and emissions embodied in trade. |
