Abstract: When the rural revitalization strategy is fully implemented,various agricultural policies have been implemented in rural areas.However,there is a huge contrast between the policy text system and the actual implementation level,resulting in a paradox of policy implementation.On the one hand,the implementation of various agricultural policies by the grass-roots government is in full swing;on the other hand,farmers and other grass-roots policy participants are calm and even indifferent to the implementation of agricultural policies.Based on the analysis of the "Ambiguity -Conflict" model as the analytical framework,this paper analyzes the process of agricultural policy implementation in Q Town,W County,and discusses the administrative implementation under the hierarchical structure,the political implementation under the political tournament,the experimental implementation under positive inertia and the symbolic implementation under sub-paralysis.It is found that in the top-down implementation path with low fuzziness,the grass-roots government generally completes the policy objectives by establishing a model of typical implementation and fostering elites' alternative implementation because of hierarchical pressure and performance evaluation;while in the highly fuzzy bottom-up implementation path,the grass-roots policy target groups finally deal with negative implementation and mechanical symbolic implementation through various formalism because of the lack of sense of participation and initiative.The paper further explains the root of the paradox of agricultural policy implementation,and on this basis,puts forward the ways to improve grass-roots government agricultural policy implementation,such as resource integration,balance of interests,farmers' participation,pluralistic linkage and so on.

Key words: implementation paradox, grassroots government, agricultural policy, ambiguity-conflict model
