中文摘要：

新能源物流系统投入决策对企业的收益和可持续发展非常重要.本文利用拓展的Hotelling模型研究竞争环境下水泥生产企业新能源物流系统投入决策行为,具体分析了一个包含物流系统投入和销售产品定价的两阶段决策问题.研究揭示了影响新能源物流系统投入的内生成本参数与博弈均衡策略的关系,以及新能源物流系统投入所产生的经济和社会效益.研究发现,当至少有一个企业选择投入新能源物流系统时,产品销售价格、消费者剩余和社会总福利相对于双方均不投入时都得到改善.最后,通过数值例子,研究了内生参数对最优策略的影响,并得出一些有意义的管理启示.

英文摘要：

The decision of the investment in the green energy based logistics system is very important for a producer to increase profits and develop sustainably. Using an extended Hotelling model, this article studies the cement producers＇ investment decision behaviors for the green energy based logistics system under duopoly competition, and develops a two-stage decision-making model including logistics system investment and product pricing. Our research finds that the equilibrium strategies are influenced by endogenous costs of the investment. Moreover, the economic and social benefits from the investment are also discussed. It is shown that both customer surplus and social welfare will be better off and the product sale price will be low when there is at least one firm choosing to invest in green energy based logistics system. Finally, numerical experiments are used to study the impact of the endogenous parameters on the optimal strategies and get some meaningful managerial insights.
