In investigating recent changes to the automotive industry production process, such as modularisation, our work emphasises the process of fragmentation of production as a configuring element of inter-firm power relationships, and as an explanatory element in working conditions. From a theoretical framework focused on power relations, we analyse by way of a selected case study how the capabilities of companies and their network positions, together with the agency of labour, shape the power relations that influence the evolution of working conditions. The study does indeed find relevant changes to inter-firm relationships, for example, within networks of assemblers and suppliers, but without a consequent re-balancing of power. This finding serves to explain differences in the evolution of working conditions between distinct companies, these conditions being fully functional to a strategy for profitability and thus difficult to reverse.

在调查汽车工业生产过程的最新变化（例如模块化）时，我们的工作强调生产分散化的过程是企业间权力关系的构成要素，也是工作条件下的解释性要素。从一个专注于权力关系的理论框架，我们通过一个选定的案例研究来分析公司的能力及其网络位置，以及劳动代理，如何塑造影响工作条件演变的权力关系。该研究确实确实发现了企业间关系的相关变化，例如，在装配商和供应商网络内部，但没有随之而来的权力重新平衡。这一发现有助于解释不同公司之间工作条件演变的差异，
