随着科技的进步和市场竞争的激烈，企业越来越多基于新的技术和硬件而对现有的产品线进行迭代升级。此外，物联网也将会带来消费理念和供应链运营模式的变化。本项目基于管理理论发展和实践需要的分析，以企业代表性产品线为研究对象，研究在新的市场特征下，决策者如何应对消费者的策略行为，如何通过换购服务提高消费者的购买意愿、提高产品的可再利用性。另外，基于物联网的发展和前景，考虑物联网的实时互联和智能感知特征对供应链结构和运营模式的影响，研究物联网环境下的供应链结构、产品升级模式和产品换购服务决策。项目重点研究三个方面的问题：（1）考虑消费者策略行为的产品升级决策；（2）基于消费者策略行为的“以旧换新”换购服务；（3）物联网环境下的产品升级和换购服务策略。项目研究将产生重要的理论成果，拓展运营管理领域的理论和方法，有助于企业理解消费者策略行为和物联网环境对管理决策的影响，提高供应链的服务水平和市场竞争力。

Along with the advances in technology and the fierce competition in market, more and more enterprises are upgrading their representative product lines based on new technologies and hardware. Furthermore, the Internet of Things (IoT) will also bring about changes in the concept of consumption and the business model of the supply chain. In this project, from the viewpoint of theoretical development of management theory and practical application, based on the key product line (or representative product line), considering the new characteristics of market, we will investigate how does the decision-maker respond to the consumer's strategic behavior and how to improve the consumer's willingness to buy and improve the reutilization of the products by the trade-in service. Moreover, based on the development and future prospect of IoT, considering the impacts of IoT's characteristic with the real-time interconnection and intelligent perception on supply chain structure and business model, we will study the supply chain structure, product upgrading mode and trade-in service in the environment of IoT. We will focus on three aspects in this project: (1) the product upgrade decisions considering the consumer strategic behavior, (2) the product trade-in service based on the consumer strategic behavior, and (3) the product upgrade and product trade-in decisions in the environment of IoT. This project research will produce some significant theatrical achievements, which will expand the theories and methods in operations management, help managers to identify and understand the effects of the consumer strategic behavior and the IoT environment on managerial decisions, and improve the service level and market competitiveness from the perspective of supply chain.
