伴随《国务院关于国家重大科研基础设施和大型科研仪器向社会开放的意见》（国发〔2014〕70号）等一系列政策文件的陆续颁布与施行，国家及部分省市对科研设施与仪器的开放共享工作予以高度关注，稳步推进科研设施与仪器资源的高效利用，不断增强其服务社会发展的效能。本文于“两新”（大规模设备更新、消费品以旧换新）政策背景下，结合辽宁省实际，针对重大科研基础设施和大型科学仪器共享服务工作展开专题研究，探索适配政策导向、贴合区域需求的共享服务路径，为提升辽宁省科技资源利用效率、助力科技创新与产业升级提供参考。

With the successive issuance and implementation of a series of policy documents represented by Opinions of the State Council on Opening Up National Major Scientific Research Infrastructure and Large-Scale Scientific Research Instruments to the Society (Guo Fa [2014] No. 70), the state and some provinces and cities have attached great importance to the opening and sharing of scientific research facilities and instruments. We have steadily promoted the efficient utilization of scientific research facility and instrument resources, and continuously enhanced their efficiency in serving social development. Against the policy background of the “Two New Initiatives” (large-scale equipment renewal and consumer goods replacement with new ones), this paper conducts a special study on the sharing service of major scientific research infrastructure and large-scale scientific instruments in combination with the actual situation of Liaoning Province. It explores a sharing service path adapted to the policy orientation and in line with regional needs, so as to provide a reference for improving the utilization efficiency of scientific and technological resources in Liaoning Province and boosting scientific and technological innovation and industrial upgrading.
