支持引导社会力量参与公共图书馆建设已成为行业内外的共识。尽管社会力量参与公共图书馆建设的制度体系已初步建立并取得了实效，但在社会力量参与动力、参与效能、培育与发展、参与的风险管理等方面仍存在一定梗阻。为此，文章从机制的优化入手，提出要提升社会力量参与的地位、强化效能保障与深度参与、培育专业的社会力量主体、加强风险防范与可持续保障，使社会力量稳定、规范、可持续地参与公共图书馆建设，为公共图书馆事业的高质量发展提供支持。

Supporting and guiding social forces to participate in public library development has become a consensus both within and outside the industry. Although an institutional framework for social participation in public library development has been preliminarily established and has yielded tangible results, obstruction persist in areas such as motivation for participation, effectiveness of engagement, cultivation and development of participants, and risk management of participation. To address this, this paper proposes optimizing mechanisms by: strengthening rights protection and incentive expectations; upholding public welfare principles and professional standards; cultivating qualified entities and professional expertise; and fortifying risk prevention and sustainable safeguards. These measures will ensure stable, standardized, and sustainable participation of social forces, supporting the high-quality development of public libraries.
