The second is the pattern of the social physics, and the important researcher include W.Reily (1929), G.K.Zipf (1949), P.d.Converse (1949), and D. L.Huff (1963) so on. The common theory basis is Newtonian law of gravity, and they put forward some indexes, usually using the population of two cities to determine the breakpoint.In the latter years, the saturation theory was founded in Hover commercial college, and the applying of commercial geography is clear.The third is the central-land theory, establishing the scale system of commercial center or business hinterland. After the world war, the traditional commercial geography turned out to be modern commercial geography.In research method, hum an behavior geography, time geography, structure geography were involved.
