【摘要】 通过建立天然橡胶需求函数模型,估算了天然橡胶的需求弹性系数和天然橡胶与合成橡胶的替代弹性系数。研究结果表明:天然橡胶属于需求缺乏弹性的商品;从经济学角度证明天然橡胶与合成橡胶在一定程度上可以相互替代。更多还原

【Abstract】 The text calculated the price elasticity of demand of NR(natural rubber) and the cross elasticity of demand of NR and SR by establishing the model of NR’s demand function.The results show:firstly,NR is product of price inelasticity of demand;Secondly,NR and SR can be substituted to a certain extent,but not completely from the perspective of the economics.更多还原
