Empirical studies of innovation in the knowledge-driven economy

This introduction to a special issue of EINT surveys a collection of ten papers that study various aspects of innovation and knowledge management and their impact on performance at the firm level for a number of countries. These studies have been conducted using data drawn from innovation surveys combined with data from a number of other sources. The issue illustrates the value of these surveys in improving our understanding of innovation in firms and raises a number of questions for future work in this area.
