Grassroots Innovation is a typology of innovation that develops in civil society and is driven by social and ideological concerns. This paper focuses on the strategies of resistance developed by Grassroots movements in response to capture and mainstreaming processes and on the role that ideology has in the evolution of Grassroots Innovation.

The study refers to the Arenas of Development framework. The adoption of a flat ontology allows to overcome the dichotomy between niche and regime and the focus on market breakthrough. It permits to consider social and political issues, and interactions between different arenas with different perspectives. The notion of actor-world used to define arenas' focus and boundaries allows to stress the role of ideology in evolutionary pathways.

The analysis is based on a case study on Organic in Europe, that leads to consider three different arenas: the Grassroots arena, the EU Common Agricultural Policy arena, and the Global retail/agrifood arena. The arenas approach Organic with different lenses, interact and co-evolve. The recent ideological repositioning of the Grassroots arena brought it to the development of a strategy of resistance based on alliances with other arenas of civil society and on both confrontation and separateness with the other Organic arenas.

草根创新是一种在公民社会中发展的创新类型，受社会和意识形态问题的驱动。本文重点关注草根运动为应对捕获和主流化过程而制定的抵抗策略，以及意识形态在草根创新演变中的作用。

该研究参考了发展框架的竞技场。采用扁平本体可以克服利基和制度之间的二分法以及对市场突破的关注。它允许以不同的视角考虑社会和政治问题，以及不同领域之间的互动。用于定义竞技场的焦点和边界的演员世界的概念允许强调意识形态在进化途径中的作用。

该分析基于欧洲有机的案例研究，该研究导致考虑三个不同的领域：草根领域、欧盟共同农业政策领域和全球零售/农业食品领域。竞技场以不同的视角接近有机，互动和共同进化。草根领域最近的意识形态重新定位使其发展出一种基于与公民社会其他领域的联盟以及与其他有机领域的对抗和分离的抵抗战略。
