This study looks at the international impact of leading economics journals published in Spain. For this purpose data were collected on the number of times that articles published in Spanish journals are cited in international journals on the ISI Journals lists. Constructing these kind of impact factor enables us to stablish a new ranking of Spanish leading journals arising from their international impact. This has been a neglected aspect in previous work that constructed impact factors for Spanish academic journals. Finally, the comparison of the results with those obtained for the leading Italian, French or German journals consents us to identify the basic elements which favour the internacionalization of these national economics journals.
