乡村基层治理创新是实现乡村基层治理现代化转型的关键。本研究运用扎根理论的方法对农业农村部推介发布的 38 个第三批全国乡村治理典型案例进行研究，探索乡村基层治理创新的制度逻辑。研究发现，制度复合构成乡村基层治理创新的制度逻辑，制度复合主要有三条路径：制度赋能乡村自治进行制度性自治；制度嵌入乡村自治的乡土性而生成自治性制度；制度吸纳以制度营造为中介通过“激活-反馈-动态均衡”的机制连接乡村自治与制度创新建构而形成乡村自治优化-制度创新建构的反馈循环。制度营造通过引领性制度安排以及过渡性制度安排共同实现，前者构成乡村基层治理制度创新的动态域与理论基础，后者构成制度创新的参照系与实践基础。制度复合有利于调和乡村基层治理中正式制度与非正式制度的张力，在正式制度空间与非正式制度空间的交汇处构建共识性制度空间，为乡村基层治理制度创新拓展空间，为治理实践增益。

The innovation of rural grass-roots governance is the key to realize the modernization transformation of rural grass-roots governance.This study uses the grounded theory method to study 38 typical cases of the third batch of national rural governance recommended and released by the Ministry of Agriculture and Rural Affairs, and explores the institutional logic of rural grassroots governance innovation.The research finds that the institutional combination constitutes the institutional logic of rural grass-roots governance innovation.There are three main ways to compound the institutional combination of rural grass-roots governance: the institution enables rural autonomy to carry out institutional autonomy;The institution is embedded in the local nature of rural autonomy and generates the autonomous institution;Institutional absorption connects rural autonomy and institutional innovation construction through the mechanism of "activation-feedback-dynamic equilibrium" with institutional construction as the intermediary, thus forming a feedback loop of rural autonomy optimization and institutional innovation construction.Institutional environment construction is realized through both leading institutional arrangement and transitional institutional arrangement. The former constitutes the dynamic domain and theoretical basis of institutional innovation in rural grass-roots governance, while the latter constitutes the reference frame and practical basis of institutional innovation.Institutional compound is conducive to harmonizing the tension between formal institutions and informal institutions in rural grass-roots governance, constructing consensus institutional space at the intersection of formal institutional space and informal institutional space, expanding space for institutional innovation in rural grass-roots governance and enhancing governance practices.
