Anschließend an die breite Literatur zur Untersuchung von Produktivitätsdifferentialen zwischen international aktiven und nicht international aktiven Unternehmen liefert der vorliegende Beitrag erstmals Ergebnisse für Deutschland die sowohl Export- als auch Importaktivitäten berücksichtigen. Für Kleinst-, kleine und mittlere Unternehmen findet sich folgende Hierarchie: Unternehmen, die entweder exportieren oder importieren sind produktiver als Unternehmen, die ausschließlich auf dem nationalen Markt aktiv sind; Unternehmen, die sowohl exportieren als auch importieren, weisen die höchste Produktivität auf. Unternehmen die nur importieren sind zumeist produktiver als Unternehmen, die nur exportieren. Dies gilt in beiden Teilen Deutschlands und sowohl für wissensintensive als auch für nicht wissensintensive Industrien. Der Vergleich wissensintensive vs. nicht wissensintensive Industrien zeigt in allen Größenklasse eine deutlich stärkere Beteiligung wissensintensiver Unternehmen an internationalen Aktivitäten. Signifikante Unterschiede hinsichtlich der Produktivitätsprämien konnten auf der Ebene der Größenklassen jedoch nicht gefunden werden.
