概要	Input-Output Structural Decomposition Analysis (IO-SDA) is an economic-environmental accounting method rooted in Wassily Leontief's input-output framework. It decomposes changes in economic activity and associated environmental impacts (emissions, resource use) over time into components reflecting technological change, demand shifts, and structural economic reorganization. Rose, Chen, and others formalized SDA in the 1980s–1990s for sustainability analysis.	Ecosystem Services Valuation (ESV) is a framework pioneered by Costanza and colleagues (1997) that assigns economic value to the benefits nature provides to humanity—from pollination and water purification to climate regulation and cultural enjoyment. Formalized in the Millennium Ecosystem Assessment (2005) and The Economics of Ecosystems and Biodiversity (TEEB 2010), ESV bridges ecology and economics to make the invisible value of ecosystems visible to policymakers and markets.
