The purpose of the present article is to demonstrate the necessity of focusing on interfirm interactions when analysing the rise of socially responsible practices. The first section highlights problems with the standard business case's explanations for the connection between economic and socio-environmental performance, highlighting the limitations of this approach's firm-centric reasoning. A similar critique is offered as regards studies that focus on green/sustainable supply chains -simply bringing suppliers into the analysis adds to the range of actors being covered but does little to identify existing gaps in the literature. Section 3 uses the example of the automotive industry to show how the inconsistency between corporate social responsibility (CSR) discourse and practice becomes clear when interfirm interactions are taken into account. The conclusion suggests that achieving real progress in the development of socially responsible practices requires the construction of a theory of interfirm social responsibility based on an institutionalist framework.
!Over the past 20 years, corporate social responsibility (CSR) has become a central issue in corporate life and the driver behind many social science publications. One widely debated topic is corporate motivation. The question at this level is what incentives firms might have to implement CSR actions, defined in this paper as 'practices that improve the workplace and benefit society in ways that go above and beyond what companies are legally required to do' (Vogel, 2005: 2). !There are several ways of addressing this topic. Garriga and Melé (2004), for instance, have identified four main families of explanations, each of which can be broken down into several theories. The first two are called the political and ethical approaches. They converge to the extent that both justify CSR on the basis of motives transcending business life, considering that it is companies' duty to adopt socially responsible practices because they belong to a community that is greater than themselves. A third approach, revolving around so-called integrative theories, emphasises the idea that social demands can be compatible with a company's economic interest. Stakeholder theory (Donaldson & Preston, 1995; Freeman, 1994) explains, for instance, that companies must satisfy a range of interested parties -such as NGOs, customers, suppliers and residents' associations -but also shareholders. The idea here is that it can be rational to take measures that reduce short-term profits if they satisfy the interests of stakeholders' groups that are deemed to be strategic. In reality, this approach broadens the range of objectives that a company should seek to attain, while
