构建国家科研论文和科技信息高端交流平台（以下简称“高端交流平台”），对于促进科技成果交流、顺应开放获取趋势、把握科研范式变革机遇、及时共享科技信息和整合共享平台都有着重要的价值和意义。国外科学资助机构在探索开放获取领域政策与推动高端交流平台建设方面呈现出开放共享已成共识、指定存储多方汇交成为常态、版权政策日趋完善的发展态势。国家自然科学基金委员会在推动开放获取与平台建设方面取得了开放获取政策日趋落地与系统建设稳步推进的实践成效，但还面临一些挑战。在发挥科学基金优势助力国家科研高端交流平台建设上，需要强化顶层设计与战略谋划、坚持需求导向与平台思维、平台内容建设，坚持四个并重、统筹推进开放获取中国方案。

To promote the exchanges of scientific and technological results, conform to the trend of open access, grasp the opportunities of scientific research paradigm shift, and integrate the sharing platforms, it is of great value and significance to construct the national high-end exchange platform for scientific research papers as well as scientific and technological information (hereinafter referred to as "high-end exchange platform"). Foreign research funding agencies have shown a development trend in which the consensus on open sharing in terms of open access policies and construction of high-end exchange platform has been reached, multi-party submission  and designated storage has become the norm, and copyright policies have been increasingly improved. In promoting open access and the platform construction, the National Natural Science Foundation of China (NSFC) has achieved practical results in the gradual implementation of open access policies and steady progress in the upgrade of open access platform, but it still faces some challenges. In giving full play to the role of NSFC to facilitate the construction of high-end exchange platforms for national scientific research, it is necessary to strengthen top-level design and strategic planning, adhere to demand orientation and platform thinking, pay attention to four aspects of content selection and coordinately promote the Chinese approach to open access.
