论当代中国马克思主义民族特色建构的途径

中国马克思主义民族特色是中国特色社会主义理论的本质所在。不断赋予当代中国马克思主义的鲜明民族特色就是要形成鲜明的中国特色社会主义理论。从马克思主义中国化的成就看，民族特色首先要重点建设特色社会主义理论的民族内容，要突出对马克思主义理论的民族性解读，要把民族精神融入当代中国马克思主义理论，使之成为民族特色的核心。所以，重视民族内容建设、民族认识方法和民族核心价值建设是构建当代中国马克思主义鲜明民族特色的主要途径。

Research on information sharing between a traditional retailer and an e-retailer based on price and service competitions

Based on the reality background of rapid development of e-commerce and information technology, the demand information sharing is studied between a traditional retailer and an e-retailer with price and service competitions. The Nash game models of pricing and service decisions are established in two cases: sharing and non-sharing market demand information between the traditional retailer and the e-retailer. The corresponding optimal pricing, the optimal service level strategies, and the optimal maximum expected profits have been achieved. Theoretical and numerical analyses show that the effects of the forecast information on the optimal pricing and service strategies are inconclusive, which depend on the values of parameters in the model. When the difference of the market shares between the two retailers is larger, the price competition is more fierce, and the service competition degree is less, it is more beneficial to the implementation of voluntary information sharing or the incentive contract of information sharing.
