The index represents business optimism in the production sphere of the national economy. It is calculated based on the survey of the management positions representatives. The 50 points indicator’s mark shows that over the accounting period the services sector neither expanded nor reduced. Exceeding the level mark means the sector growth. The indicator level below the 50 points mark means the sector deterioration.
Since more than 60% of GDP is contributed by services sector, this index is of lower significance than a similar one for the services sector.
