Sektorniveau

Sektorniveau refers to the level of analysis or data aggregation that is organized around economic sectors rather than the entire economy or individual firms. It focuses on how different sectors contribute to overall performance, such as growth, employment, productivity, or investment, and how sector-specific policies or conditions affect outcomes.

In statistics and national accounts, sectors are defined by standardized classifications (for example ISIC, NACE, or NAICS), which allow the calculation of sector shares of GDP, employment, output, and productivity. Data gathered at the sektorniveau can be sourced from national statistics offices, Eurostat, the OECD, and related agencies. The sectoral breakdown helps researchers and policymakers compare trends across agriculture, industry, services, and other segments, and to monitor structural change over time.

The sektor level is widely used in policy analysis and economic planning. It supports evaluating sector-specific policies—such as industrial policy, labor market programs, or energy transition measures—and in assessing how shocks or reforms propagate across different parts of the economy. For example, analysts may study how manufacturing productivity evolves relative to services, or how energy intensity varies by sector.

Limitations of the sektorniveau approach include internal heterogeneity within sectors, which can mask differences among sub-sectors or firms. Cross-sector linkages, data lags, and inconsistencies in classifications across countries can also complicate comparisons. Nevertheless, sektorlevel analysis remains a fundamental tool for understanding structural dynamics and for designing targeted interventions.
