Összefoglaló	A computable general equilibrium (CGE) model is a numerical simulation of an entire economy in which optimizing producers and consumers interact through markets that all clear simultaneously. Building on Walras's general-equilibrium theory and a benchmark social accounting matrix, a CGE model is calibrated to reproduce a base-year economy and then solved for the new vector of prices and quantities that would prevail under a counterfactual policy — a tax reform, a tariff change, a carbon price — capturing how the shock reverberates and re-equilibrates across every market.	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.	The location quotient (LQ) is a simple descriptive index that measures how concentrated an industry is in a region relative to a larger reference area, usually the nation. It is the ratio of the industry's share of local employment (or output) to its share of national employment. An LQ above one means the region is more specialized in that industry than the nation as a whole; an LQ below one means it is under-represented.
