摘要
从一个基本模型出发 ,考察了有无IT投资的零售市场定价、市场份额和利润 ,研究了不同进货成本的零售商IT投资的条件及其市场均衡 ,运用数理方法分析了以上三种市场情况 .研究表明 ,不考虑IT投资 ,零售商r1和r2 对于同质产品定价相同 ,获得相同的市场份额与利润 ;考虑r1和r2 非均衡的IT投资 ,则二者的利润都低于投资IT前的情形 ,零售商缺乏内在的投资激励 ;考虑r1和r2 的进货成本不同 ,成本低的零售商有投资IT的可能 .
On the basis of a basic model, the market equilibrium price, market share and profit were considered with the IT investment or without IT investment. The conditions of IT investment and the market equilibrium were researched concerning the retailers with different stock cost. Three markets were analyzed by mathematic method and a conclusion was drawn: if the IT investment wasn′t considered, retailer 1 and retailer 2 would get the same price, market share and profit; if the IT investment was considered, their profit would decrease and their internal spur would lose; if the different stock cost was considered, the retailer with low cost would have the possibility of IT investment.
