将社会嵌入分解为结构嵌入、关系嵌入、制度嵌入、价值嵌入四个维度，通过对不同区域、不同类型的8个科技小院进行跟踪调研发现，科技小院普遍存在四种脱嵌样态：技术供给与乡村产业发展需求间存在结构性错位，多元主体协同不足制约技术转化效能，短期项目运行制约技术服务持续嵌入，技术传播过程存在价值认知偏差。进一步分析表明，上述脱嵌样态背后，存在结构性、关系性、制度性与价值性四重阻滞机理。在此基础上，提出科技小院应从资源嵌入向协同共生转型，构建以全产业链为牵引、以经营主体为枢纽、以制度重构为保障、以价值引领为导向的系统性纾解方略，推动科技小院从单向的技术供给者转为双向赋能的产业共建者，从而破解其“技术悬浮”困境，为推进乡村全面振兴、助力农业强国建设提供学理支撑与实践路径。

By constructing a “platform–farmer” analytical framework and drawing on a case study of D Village in northern Hunan, this research finds that a comprehensive service platform established by the village collective systematically reorganizes dispersed smallholder farmers via four interrelated mechanisms: land consolidation, integrated service provision, benefit linkage, and coordinated decision-making. This model unifies service scale and production precision, thereby resolving the “Who will farm” dilemma. The underlying logic lies in that the platform effectively addresses the shortage of agricultural management entities by establishing an organized service network, realizing service-oriented economies of scale through a virtual contiguous farming model, thereby overcoming the constraints of land fragmentation, creating diversified value-added space through industrial chain extension and multifunctional agricultural development, significantly improving production and management efficiency, and mitigating burden of production risks traditionally borne by individual farmers by establishing a community-based risk-sharing mechanism. This practice transcends traditional entity substitution or service outsourcing models, preserves farmers’ principal operating status of agricultural production, and explores a viable path to organically connect smallholders with modern agriculture through governance structure innovation.
