Despite the growing interest of sustainability transition studies on the role of business actors in shaping transitions, the institutionalized logic of the capitalist enterprise underlying such agency has been overlooked. However, such logic might be understood as a dominant regime that leads to unsustainable systems.

We intend to contribute to transitions research by focusing on the agency of social enterprises as non-dominant actors searching for challenging and transforming the institutionalized logics in the business system. Therefore, we disentangle the institutional mechanisms driven by social enterprises by proposing a theoretical model built upon a literature review of sustainability transitions from institutional perspectives, offering a set of explanatory propositions to allow empirical examination. Those mechanisms and propositions operate at three levels: inside the individual, inside the niche, and at the interplay between the niche and the business regime. Finally, we include a real-world example of a social enterprise to illustrate the model.

尽管可持续性转型研究对商业参与者在塑造转型中的作用越来越感兴趣，但这种机构背后的资本主义企业的制度化逻辑却被忽视了。然而，这种逻辑可能被理解为导致系统不可持续的主导制度。

我们打算通过关注社会企业作为非主导行为体的代理来寻求挑战和转变商业系统中的制度化逻辑，从而为转型研究做出贡献。因此，我们提出了一个理论模型，该模型建立在从制度角度对可持续性转型进行文献回顾的基础上，解开社会企业驱动的制度机制，并提供了一套解释性命题以进行实证检验。这些机制和命题在三个层面上运作：个人内部、利基内部以及利基与商业体制之间的相互作用。最后，我们包含一个社会企业的真实示例来说明该模型。
