Structural economic analysis (SEA) can be characterized as addressing means-ends problems at the systemic level. The paper argues that SEA can provide the theoretical tools for a broader field of enquiry, where the production system shapes the constraints and opportunities not only of a ‘systemic actor’ who pursues objectives on behalf of the entire system, but also of a variety of possible political-economic actors who pursue their own objectives. Doing so requires three analytical steps. First, instead of assuming the relevant actors at the outset, each model in SEA can be taken as suggesting different social aggregations that might count as actors. Second, productive structure can be interpreted, from the viewpoint of different actors, as imposing different constraints and offering different opportunities to those actors. Third, we need to study which aggregations will come to count as the relevant actors in the situation under analysis.

结构经济分析 (SEA) 可以表征为在系统层面解决手段-目的问题。该论文认为 SEA 可以为更广泛的研究领域提供理论工具，其中生产系统不仅塑造了代表整个系统追求目标的“系统参与者”的约束和机会，而且塑造了各种追求自己目标的可能的政治经济参与者。这样做需要三个分析步骤。首先，不是一开始就假设相关的参与者，SEA 中的每个模型都可以被视为暗示可能算作参与者的不同社会聚合。其次，从不同参与者的角度来看，生产结构可以解释为对这些参与者施加不同的约束并提供不同的机会。第三，
