sektorsektoren

Sektorsektoren is a term found in some Nordic economic and regional planning writings to describe a framework for organizing economic activity into two levels: broad sectors and their more detailed subsectors. The concept aims to capture how large domain groups of activity are composed of finer activities and how these layers interact within an economy.

In practice, analysts align sectors and subsectors with standard industrial classifications such as NACE or SIC to create a hierarchical map of economic activity. This enables examination of structural changes, such as transitions within a broad sector from traditional to more advanced subsectors, or shifts in employment and investment across the subsectors that comprise a sector. Data typically come from national accounts, industry surveys, labor statistics, and trade figures, which can be aggregated or disaggregated to study sector-sektor dynamics.

Applications of the sektorsektoren framework include analyzing intersector linkages, assessing resilience to shocks, and planning regional development and policy interventions. It supports methods such as input-output analysis and network models by providing a nested view of activity, where subsector performance influences and is influenced by the broader sector.

Limitations and cautions include a lack of universal standardization, which can hinder cross-country comparability. The approach may introduce complexity and requires careful alignment with established classifications to avoid ambiguities. When used, it is often complemented by standard sectoral analyses.
