中文摘要：

资源共享作为资源优化配置与利用效率提升的一种重要方式，逐渐成为国内外学者关注的重点。但到目前为止，资源共享的内涵和本质等基本问题并未得到系统梳理和深入解读。本文在对共享、资源及资源共享等基本定义的已有研究成果进行综述的基础上，分析相关学科在关注点、研究对象、研究方法等方面对资源共享的认识。基于此，对资源共享概念进行再界定，提出资源共享存在的3个本质特征，包括以利益交换为基本前提、通过产权让渡行为而形成非独占关系以及满足稀缺方的需求。进一步论述了资源共享的产权转移条件和资源匹配条件，以期对资源共享的相关理论体系建设和资源共享实践提供依据。

英文摘要：

As an important way to optimal allocation and utilization efficiency, resource sharing becomes a focus recently. However, the nature of resource sharing and its basic problems have not been interpreted systematically. This paper summarizes the characters and shortcomings of the basic and expansive definition of resource sharing. And then we analyze the limit of related research because of the concern points, the objects and research methods. Based on that, we give the definition of resource sharing and the characters of definition elements and put forwards three basic characters, which including the interests exchanging as the basic premise, property right transferring to the formation of non-exclusive relationship and satisfying the demanders＇ need. Further, we discuss the conditions of property rights transferring and conditions of matching, which is of great meaningful for the theory construction of resource sharing and the guiding of practice.
