根据经济学上替代的定义,随着商品价格上升,商品需求量下降,替代品需求量上升。据此,根据江苏省数据对移动电话与固定电话市场进行定量分析,建立模型,发现虽然当前江苏固定电话用户数、通话量及收入受移动电话冲击较明显,但两者并不呈现经济学意义上的替代关系,移动电话与固定电话的融合将是发展趋势。
According to the definition of economically viable substitutes, demand for substitutes has risen as the price of commodities has risen, demand for substitutes has soared. Based on this, based on the data of Jiangsu Province, we quantitatively analyze the market of mobile phones and landline phones and establish a model. It is found that although the current number of fixed-line users, the amount of calls and their revenues in Jiangsu Province are more obviously affected by mobile phones, the two do not show any economic significance On the alternative, the convergence of mobile phones and landline phones will be a trend.
