The main economic activities of Bad Zwischenahn were and are based on tree nurseries, the food industry (sausage and ham production), and resort community services for the well to do urban population of Oldenburg and Bremen.
Peamised majandustegevused Bad Zwischenahnis põhinesid ja põhinevad puukoolidel, toiduainetetööstusel (vorsti ja singi tootmine) ning puhkuseteenustel Oldenburgi ja Bremeni linnarahva heaoluks.
