2.3 Co-Publications
The number of co-publications provides information on the main emphasis of joint scientific
publications in the individual disciplines. The section that follows presents rankings for each of
the countries studied within the framework of this analysis and shows which countries tend to
work together in the various disciplines. Not only will cooperations between the countries of this
analysis be investigated, but co-publications with other countries throughout the world will also
be taken into account. For Indonesia, Malaysia, Singapore, Thailand and Vietnam copublications
with the EU-27 are shown separately. Due to co-publications within the EU,
publications of the 27 EU member states cannot be added up. This ranking will be performed for
two periods, each five years in length, as well as for the period as a whole. This allows us to
detect changes in co-publication practice. As was the case for co-publications according to
country, no direct comparison is possible here between the individual disciplines due to the fact
that each discipline has different communication habits.
