提升新型公共文化空间的可持续发展能力是推动公共文化服务高质量发展的关键抓手。探究新型公共文化空间可持续发展的能力维度及条件组态，能够为新型公共文化空间的高效能运作提供重要学理参考。文章综合运用元综合分析方法和定性比较分析方法，基于国内外主流数据库筛选出114篇高质量样本文献，经编码、提炼与综合，构建新型公共文化空间可持续发展能力的MCSI模型。运用模糊集定性比较分析方法，基于40个新型公共文化空间案例，识别新型公共文化空间可持续发展能力提升的组态路径。研究发现，新型公共文化空间可持续发展能力包括管理、协同、服务、创新四个相互关联的维度；创新突破型、管理驱动型、服务整合型和效能提升型是新型公共文化空间可持续发展能力提升的关键组合路径。据此从聚焦优势资源，打造亮点品牌；深化服务职能，回应文化需求；搭建协同基座，凝聚跨界资源方面进行了启示性反思。

Enhancing the sustainable development capability of new public cultural spaces is a key measure to promote the high-quality development of public cultural services. Exploring the capability dimensions and conditional configurations of the sustainable development of new public cultural spaces can provide important theoretical references for their efficient operation. By comprehensively applying meta-synthesis analysis and qualitative comparative analysis, 114 high-quality sample literatures were selected from mainstream domestic and foreign databases. Through coding, extraction, and synthesis, the MCSI model for the sustainable development capability of new public cultural spaces was constructed. Using fuzzy-set qualitative comparative analysis (fsQCA), based on 40 cases of new public cultural spaces, the configuration paths for improving their sustainable development capability were identified. The study found that the sustainable development capability of new public cultural spaces includes four interrelated dimensions: Management, Collaboration, Service, and Innovation. The key combination paths for enhancing such capability are innovation-driven, management-led, service-integrated, and efficiency-improving. On the basis of these findings, enlightenment reflections are put forward in terms of focusing on advantageous resources to build distinctive brands, deepening service functions to respond to cultural needs, and establishing a collaborative foundation to integrate cross-sector resources.
