“…Since the work of Garfield et al (1964), the study of citations to scientific publications has received increasing attention from network analysts, and the network analysis literature includes a growing number of contributions on identification of the so called main path, that is, the main flow of ideas underlying the field of analysis (Necmi Kemal Avkiran and Alpert 2015;Nerur et al 2008;Whitley and Galliers 2007); technological developments and trajectories in various scientific fields (Barberá-Tomás et al 2011;Bekkers and Martinelli 2012;Bhupatiraju et al 2012;Breschi and Lissoni 2003;Epicoco 2013;Fontana et al 2009;Martinelli 2012;Mina et al 2007); and emerging knowledge trends within disciplines (Ding et al 2013;Emrouznejad and Marra 2014;Fan et al 2014;Lampe and Hilgers 2014; J. S. Rotolo et al 2013). Network analysis assumes that, in a citations network (see Figure 1), document B cites document A, in other words, B relies on A to some extent.…”

Development and application of the Data Envelopment Analysis (DEA) method, have been the subject of numerous reviews. In this paper, we consider the papers that apply DEA methods specifically to financial services, or which use financial services data to experiment with a newly introduced DEA model. We examine 620 papers published in journals indexed in the Web of Science database, from 1985 to April 2016. We analyse the sample applying citations network analysis. This paper investigates the DEA method and its applications in financial services. We analyse the diffusion of DEA in three sub-samples: (1) banking groups, (2) money market funds, and (3) insurance groups by identifying the main paths, that is, the main flows of the ideas underlying each area of research. This allows us to highlight the main approaches, models and efficiency types used in each research areas. No unique methodological preference emerges within these areas.Innovations in the DEA methodologies (network models, slacks based models, directional distance models and Nash bargaining game) clearly dominate recent research.For each subsample, we describe the geographical distribution of these studies, and provide some basic statistics related to the most active journals and scholars.

“…Analysing the EPs for the leading firms allows for a determination of the leading firms' position within the global network. This approach has been validated in studies on fuel cells [54], medical knowledge, telecommunications switching [57], data communication standards, and connectivity analysis [53].…”

Comparing the International Knowledge Flow of China’s Wind and Solar Photovoltaic (PV) Industries: Patent Analysis and Implications for Sustainable Development

Climate-relevant technologies, like wind and solar energy, are crucial for mitigating climate change and for achieving sustainable development. Recent literature argues that Chinese solar firms play more active roles in international knowledge flows, which may better explain their success in international markets when compared to those of Chinese wind firms; however, empirical evidence remains sparse. This study aims to explore to what extent and how do the international knowledge flows differ between China's wind and solar photovoltaic (PV) industries? From a network perspective, this paper develops a three-dimensional framework to compare the knowledge flows in both explicit and tacit dimensions: (i) inter-country explicit knowledge clusters (by topological clustering of patent citation network); (ii) inter-firm explicit knowledge flow (patent citation network of key firms); and, (iii) inter-firm tacit knowledge flow (by desktop research and interviews). The results show that China's PV industry has stronger international knowledge linkages in terms of knowledge clustering and explicit knowledge flow, but the wind power industry has a stronger tacit knowledge flow. Further, this study argues that the differences of global knowledge links between China's wind and solar PV industries may be caused by technology characteristics, market orientation, and policy implementation. This suggests that these industries both have strong connections to global knowledge networks, but they may involve disparate catch-up pathways that concern follower-modes and leader-modes. These findings are important to help us understand how China can follow sustainable development pathways in the light of climate change.

“…Accordingly, the patent citation analysis provides useful information about the knowledge that has influenced an invention. By analyzing the sequences of patent citations, one can follow the trajectories of knowledge flow (Verspagen, 2007;Fontana, Nuvolari, & Verspagen, 2009;Martinelli, 2011).…”
