'die Einführung' and 'die Abschaffung' are opposites here. With 'Einführung', something new is officially started or put into use, for example a rule or a law. With 'Abschaffung', something existing is officially ended. So the difference is the direction: 'Einführung' brings something new in, while 'Abschaffung' takes something away again or ends it.
