subsystemseconomy

Subsystemseconomy is a term used in discussions of systems thinking to describe economic activity bounded within a defined part of a larger system. It treats the bounded portion as a self-contained economy, with its own flows of goods, services, capital, and information, while remaining connected to other parts of the system through feedbacks and exchanges. The concept highlights how internal structure, boundaries, and inter-subsystem links shape economic outcomes in ways that may depart from aggregate macroeconomic indicators.

Boundaries for a subsystemseconomy are selected for analytical purposes and can be geographic (a city or region), organizational (a multinational's value chain), industry-based (an technology sector), or platform-based (an online marketplace network). Analysts study supply chains, production networks, financial flows, and information exchange within the subsystem, and examine how external shocks propagate across partners and boundaries. Methodologies include input-output analysis, network theory, system dynamics, and agent-based modeling.

Applications of the subsystemseconomy approach include urban and regional planning, corporate strategy, and policy evaluation, where understanding the internal structure of submarkets helps forecast resilience, efficiency, and spillovers. Examples include a city’s energy-subsystem economy, a manufacturing cluster’s value chain, or a digital platform’s data and advertising ecosystem.

Critiques center on definitional ambiguity and boundary sensitivity, the risk of double counting when interfacing subsystems, and the potential to overlook broader macroeconomic constraints. Proponents argue that it complements micro- and macro-level analysis by revealing internal mechanisms, feedback loops, and non-obvious interdependencies within complex economies.
