摘要
我国是产钨大国,钨资源储量520万t,钨的产量及出口量均居世界第一。钨是重要的战略金属,其价格浮动较大,而且往往受政治、经济、环境多方面的影响,然而多数学者只是对钨价格做定性的分析。根据采集到的近30a钨的产量和消耗量数据,从最基本的供需角度入手,定量分析钨的价格受供需因素影响的大小,利用E-VIEWS软件采用LS最小二乘回归法,得出钨价格与产量是有效的正相关关系,与需求没有有效的相关性,即钨价在世界范围内与供给量的变化一致性比较接近,在需求方面则不确定。
Base on the tungsten's production and consumption data in the recent 30 years, start from the most basic supply and demand angle, quantitative analyze how much the supply and demand factors' affect on Tungsten~ price, use software E-VIEWS and adopt LS( Least-squares regression method) , there is an effective positive correlation between the tungsten's price and yield, and there is no effective correlation between tungsten's price and demand, in other words, the changes in tungsten's value normally vary with changes of its supply in worldwide, but don't vary with its demand.
