interfirm

Interfirm refers to interactions and relationships between separate firms in economic activity. It encompasses competitive and cooperative relationships that cross organizational boundaries, including supplier-buyer ties, strategic alliances, joint ventures, licensing, franchising, and various forms of interorganizational collaboration. The term is commonly used in economics, management, and operations research to contrast with intrafirm activities conducted within a single corporation.

Interfirm relations can take many forms. Interfirm competition occurs when firms vie for the same customers or market share. Interfirm collaboration includes long-term arrangements such as strategic alliances, joint development projects, supply agreements, outsourcing, and networks that coordinate activities across firms. Interfirm networks and supply chains rely on flows of information, materials, and capital, often requiring governance mechanisms to reduce transaction costs and align incentives.

Theoretical approaches include transaction cost economics, which analyzes governance structures (market, hybrid, or hierarchy) to minimize costs, and network theory, which emphasizes pattern of ties and knowledge exchange. Relational contracts and informal promises can supplement formal agreements to manage opportunism in long-term partnerships.

Benefits of interfirm arrangements include access to complementary capabilities, scale economies, risk sharing, and faster innovation. Risks include misaligned incentives, hold-up, dependence, information asymmetry, and opportunistic behavior. Effectiveness depends on contract design, trust, governance, and the ability to coordinate across organizational boundaries.

In practice, interfirm activity shapes supply chains, technology transfer, franchising systems, and industry ecosystems. Antitrust and competition policy monitor interfirm coordination to prevent anti-competitive behavior while permitting beneficial collaboration.
