สรุป	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.	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.
