产品处置是构成消费者行为的重要阶段，现有研究主要从回收、转售等单一处置模式展开，考察了产品因素、决策者因素的影响作用。然而，资源稀缺情境会对消费者产品处置行为产生怎样的影响？已有文献尚未对这一问题进行探讨。本项目将主要（1）基于消费升级的时代背景，刻画当下消费者的产品处置模式与心理动机；（2）从外在情境因素出发，检验资源稀缺对产品处置不同行为模式的影响，在生命史理论框架下比较个体层面与社会层面资源稀缺情境下产品处置行为的差异；（3）揭示不同层面资源稀缺对产品处置行为产生影响的心理机制，探索这些效应的边界条件；（4）识别资源稀缺情境下消极产品处置行为的干预策略，检验采用何种方式能够促进消费者做出资源节约型、环境友好型的产品处置决策。本项目将拓展产品处置行为的研究视角，丰富资源稀缺的相关理论，并为公共政策制定者、环保机构及二手交易市场中的企业提供政策建议与管理启示。

Product disposition is an important stage of consumer behavior. The extant research mainly focused on a single mode of disposition behavior such as recycling and resale, and investigated antecedents related to the product and the decision maker. However, how resource scarcity affects consumers' product disposition behavior remains a hitherto unaddressed research question. This project will (1) examine the main modes of product disposition and corresponding motivations under the context of consumption upgrading; (2) investigate the effects of resource scarcity on different modes of product disposition, and compare the differences in product disposition behavior under individual-level and macro-level resource scarcity based on life history theory; (3) explore the psychological mechanisms underlying the above effects, and examine the boundary conditions under which different levels of resource scarcity affect product disposition behavior; (4) identify intervention strategies of negative product disposition behaviors under resource scarcity, and test how to motivate consumers to make resource-efficient and environment-friendly disposition decisions. The project will expand the research perspective of product disposition behavior, enrich the relevant theories of resource scarcity, and provide policy advice as well as managerial implications for the public policymakers, environmental protection agencies and enterprises in second-hand marketplace.
