Modern information and communication technologies (ICT) have strongly penetrated all business sectors in recent years. Furthermore, increasing digitalisation changes our economic activity and the way we participate in the working life. The ICT research department has been tracking this development by carrying out representative firm-level surveys. In 2002, the first wave of the so called ZEW ICT survey took place. Further surveys were conducted at irregular intervals in 2004, 2007, 2010 and 2014. About 4,500 German companies of the manufacturing industry and of selected service industries, which have at least five employees were interviewed at a time.

The aim of the survey is to obtain a representative picture of the diffusion and use of information and communication technologies in German companies and to analyse the consequences of their use. The survey is an important database for various further projects of the ICT research department and is also used for the development of policy recommendations.

Important results of the previous surveys are summarised in the respective ICT report:
