术语“蛛网定理”的详细信息

英译术语:

cobweb theorem

汉语语境:

西方经济学中关于动态均衡分析的蛛网定理，它的内容是考察价格波动对下一周期供求的影响，以及由此而产生的均衡变动。这一理论，运用对比供给价格弹性与需求价格弹性的方法，确立了这样三条规律： 第一种情况，供给弹性小于需求弹性，价格和产量的波动越来越小，最后恢复平衡。第二种情况，供给弹性大于需求弹性，价格和产量的波动越来越大，离开均衡点越来越远。第三种情况，供给弹性等于需求弹性，价格和产量波动终始按同一幅度进行。

英语语境:

The cobweb theorem of dynamic equilibrium analysis in the Western economics studies the impact of price fluctuations on the supply and demand on the next cycle, and the equilibrium changes occured by it. The cobweb theory has established three rules through comparing the supply and demand elasticity. First is that when supply elasticity is smaller than demand elasticity, the fluctuation of the price and ouput is small and finally reach the equilibrium point. Second is that when suppy elasticity is greater than demand elasticity, the fluctuacion is large and finally deviate the equilibrium point. Third is that the supply elasticity is identical with demadn elasticity, the flucatuation is always in the same range.
