The article studies the differentiated strategies of two competitive distributors and further analyses the differentiated effects. The two distributors are respectively a stronger distributor which has the brand advantage and a weaker one which carries out differentiation or value-added services. The results show that the weaker distributor increases price ?market demand and unit product profit through differentiated strategies, and obtains “value of overflow”. The optimal investment strategy about differentiation is given because there exists moderate differentiation. While the stronger distributor has the free-riding behavior which also increases price and market demand, and obtains “value of overflow”. It is further found that the two distributors have different market demand increment which depends on the differentiated efficiency. Then the paper gives the threshold of the differentiated efficiency.
