Purpose
The purpose of this study is to evaluate different strands of institutional theory within the internationalization process of multinational enterprises (MNEs) in developed and emerging economies. In the light of this purpose, the authors try to fill the gap in the literature through analysing the main institutional theories: neo-institutionalism, new institutional economics, comparative capitalism and the institution-based view. Therefore, the main concern is to determine the distribution of different strands of institutional theory in its subfields in this study.

Design/methodology/approach
This study provides a profound analysis of different strands of institutional theory within the period from 1990 to 2018 in a larger sample. With a qualitative content analysis, authors reviewed 150 articles using different strands of institutional theory at both theoretical and analytical level and accessed 25 journals published in Social Science Citations Index between 1990 and 2018. In this study, authors used the inductive approach and the qualitative content analysis (Duriau et al., 2007) and adopted a research method to investigate different strands of institutional theory within the internationalization process of MNEs in developed and emerging markets (EMs).

Findings
Coders have synthesized the strands of institutional theory in detail to analyse the theoretical contribution of the study. The strands of institutional theory have been analysed both by institutional perspective and citation analysis. Coders classify the analysis level into three main categories. These are country, headquarter and subsidiary level. Our findings are related to the basic determinants and assumptions of different strands of institutional theory. Because in new institutional economics, analysis levels are country and industry. On the other hand in institution-based view, analysis levels are country and firm. Finally in comparative capitalism, analysis levels are country and region and, in neo-institutionalism analysis level is organization itself. In this study, findings show that sociology-based institutional strands, especially neo-institutionalism, are more preferred than other theories.

Research limitations/implications
This study’s content analysis is limited to scope of selected journals. However, this study may suffer from publication bias. The authors examined only peer-reviewed articles from selected journals and did not include book chapters, book reviews, editor and special issue editor articles, research notes, conference papers and congress invitations. The important theoretical limitation of this study is to clarify the different strands of institutional theory in international business literature (Aguilera and Grøgaard, 2019). The firm size of MNEs is not included in this study, but it should be involved in coding categories in future studies.

Originality/value
This study provides the largest sample up to now and covers developed markets and EMs. Authors analysed this research from four perspectives: theoretical foundation, methodology, location and entry mode choices. On the other hand, this study shows that the institutional environment not only mitigates or mediates the effects but also directs the effects on foreign direct investment’s internationalization process of location choice and entry strategies.
