governance system. Existing research has found that policy attributes, hierarchies and institutional environments are important factors leading to different modes of policy implementation. This paper integrates the two key variables of institutional coupling and situational incentive to construct a theoretical analysis framework, and then divides the policy implementation modes into four execution modes of competitive innovation, administrative utilization, symbolic leadership, and conflict adjustment, in order to open the process "black box" of the different policy implementation modes.  Through the multi-case comparative study of different party and government departments, townships and streets in L City which is to general establish legal counsel system, the theoretical presupposition is verified in this paper. At the same time, this paper finds that as the "sinking" of superior policies impacts the governance field of local governments, the two key influencing factors, institutional coupling and situational incentive, shape the response process and behavior pattern of stripe department and block department within local governments, through the dynamic mechanism of legitimacy recognition and political-economic incentive under the dual logic of legitimacy and rationality. The typification of different policy implementation modes not only expands the research related to the differentiated models of policy implementation, but also expands the research related to the organizational behavioral logic.

探究政策执行模式的差异,对于理解政策过程与中国治理体系具有重要意义。现有研究已经发现,政策属性、层级结构与制度环境是导致执行模式差异的重要因素。研究整合了制度耦合和情境激励两个变量建构了理论分析框架,进而将政策执行模式划分为竞先创新型、行政利用型、象征表率型、冲突调适型,以打开政策执行模式差异的过程 “黑箱”。通过对L市不同党政部门和乡镇街道落实普遍建立法律顾问制度的多案例比较分析,本文对理论预设进行了验证。研究发现,随着上级政策的 “下沉”冲击地方政府治理场域,在合法性与理性逻辑的双重驱动下,通过合法性确认与政治 经济激励机制,两个关键变量——制度耦合和情境激励——塑造了地方政府内部次级条块部门的政策回应过程与执行模式。不同执行模式的类型化既拓展了政策执行的差异化模式研究,也拓展了组织行为逻辑的研究。
