[目的/意义] S计划的实施促进了学术科研成果的开放获取，但仍有不足之处。通过提炼各参与主体对S计划10项原则实施过程中存在的问题，找到阻碍S计划推行的原因，并据此提出整改意见，以期推动S计划的早日实施。[方法/过程] 按照不同国别和相同国别不同参与主体的原则，确定研究资料。利用NVivo11逐行梳理国外访谈资料，并结合扎根理论程序化编码深入挖掘S计划10项原则中存在的问题。[结果/结论] 针对S计划10项原则的现存问题，从权威政府部门的认可、支持混合期刊作为过渡模式、制定成本透明的实施准则、适当延迟S计划实施时间和细化扩展S计划原则的5个方面提出整改对策。
[Purpose/significance] The implementation of Plan S has promoted the open access of academic research results, but it still has some shortcomings. By refining the problems existing in the implementation of the 10 principles of Plan S by each participant, the reasons hindering the implementation of Plan S are found..Based on this, corrective suggestions are put forward in order to promote the early realization of Plan S. [Method/process] According to the principle of different countries and different participants in the same country, the research data were determined.Use NVivo11 to sort out foreign interview data line by line, and combine grounded theory and program coding to deeply explore the problems in the 10 principles of Plan S. [Result/conclusion] According to the existing problems of the 10 principles of Plan S,this paper puts forward some suggestions and countermeasures from the following five aspects:obtaining recognition and support from authoritative government departments, supporting of hybrid periodicals as a transition mode, formulating implementation criteria of cost transparency, properly delaying the implementation time of Plan S, refinement and extension of the principle of Plan S.
