תקציר	The von Thünen model is the founding theory of agricultural land use, explaining how the pattern of farming around a market emerges from transport costs and land rent. Set out by Johann Heinrich von Thünen in his 1826 work Der isolierte Staat, it imagines an isolated city on a uniform plain and shows that the rent a farmer can pay for land falls with distance to the market, so different crops and farming intensities sort themselves into concentric rings around the city. It is the earliest formal model in economic geography and the ancestor of bid-rent and urban land-use theory.	Weber's industrial location model is the classic least-cost theory of where a manufacturing plant should locate. Developed by Alfred Weber in 1909, it finds the site that minimizes total transport cost between the sources of raw materials and the market, then adjusts that site for savings in labour cost and for the benefits of clustering with other firms. The transport optimum is found at the Weber point of the location triangle, where the pulls of material sources and the market balance — the foundational model of industrial geography.
