Methodological aspects of building up sample of reporting units for innovation survey of enterprises

Abstract

The Community Innovation Survey (CIS) is conducted by all the countries in the European Union and based on internationally harmonized definitions given in Oslo Manual. CIS conducted in the countries covered by CIS by the harmonized methodology allows for international comparisons of data on innovation. In 2009, CIS methodology was introduced in Ukraine, in order to harmonize Ukrainian statistics with the international standards.

The procedure of building up the survey sample consists of the following phases: sampling frame, stratification; clustering the strata; calculating the number of units in clusters; selecting the units for survey.

Stratification criteria in the innovation survey of enterprises are as follows: location (distribution of enterprises by location of business, by the administrative and territorial system of Ukraine), economic activity (by NACE 2010), size (by employment number). The population of enterprises with 50 employees or more (large and medium enterprises) is surveyed on continuous basis, whereas the population of enterprises with 10 to 49 employees (small enterprises) is swiveled by stratified random sampling. The key items of “Guidelines of Building up the Sample for the Innovation Survey of Enterprises”, approved by the Ukrainian State Statistics Service and used by the official statistics specialists, are highlighted.
