In recent years, author and document citation and co-citation analyses have often been applied to map the “intellectual structure” of different scientific fields, including management and international business. However, the technique of bibliographic coupling between scientific documents, which seeks to identify active research fronts in a scientific field or discipline, has been less commonly used. This study utilized this technique to identify and visualize the research fronts in the context of papers on emerging markets multinational enterprises (EM-MNEs) recently published in a wide variety of journals. The aim is not only to complement and expand the results obtained in prior studies that have used other types of systematization, such as qualitative content analysis methodology but also to propose avenues for future research.

The primary databases utilized to carry out the present research work – both comprised in the Web of Science™ (WoS) Core Collection – were: the Social Sciences Citation Index® (SCI) developed by the Institute for Scientific Information (ISI) and the Emerging Sources Citation Index. A total of 496 “peer-reviewed journal articles” published between 2014 and December 30, 2019 were retrieved. With regards to the methodology, bibliometric methods were utilized, as well as social network analysis (SNA).

Particularly, the analytical techniques employed – adopting a “quantitative” method of a deductive character – allowed the identification of the most active research “fronts” in international research related to the topic under analysis: the phenomenon of EM-MNEs.

The present study has several limitations resulting from the utilization of bibliometric methods applied in the analyses performed.

The authors believe that this research is of value for future researchers since it allows the identification of research “fronts,” which shape the vanguard of knowledge and reveal current trends and future directions in the area under examination.

This paper aims to know the dimension and scope that research on the district effect has had in the literature about industrial districts, as well as to shed some light on the connection between industrial districts and business results; or expressed differently, on how being located in an industrial district or not affects or might influence the performance of the firms located therein.

The purpose of this paper has been achieved through an exhaustive review of the empirical literature dedicated to the so-called district effect. The papers selected in the analysis were selected on the basis of the following criteria: (1) publications in scientific journals; (2) studies carried out in Spain and Italy; and (3) works published between 1994 and 2017.

The outcome of the literature review suggests, on the one hand, that the debate on the extent to which the territory influences the competitiveness of firms located in industrial districts still remains a topic of great interest. It can additionally be observed that most of the works dedicated to measuring the district effect have done so using three dimensions: (1) productivity/efficiency; (2) international competitiveness; and (3) innovation.

From a theoretical perspective, the findings of this paper make it possible to carry out an integrating proposal for the measurement of the district effect which revolves around three dimensions (productivity/efficiency; international competitiveness; and innovation).

This paper makes a twofold contribution to the literature: (i) it brings together the most important empirical contributions that measure the competitive advantages obtained by firms located in industrial districts through the district effect; and (ii) it theoretically and empirically establishes the essential dimensions of that effect.
