Abstract
This study attempts to characterize the literature related to input–output analysis between 1990–2017 through bibliometric analysis technology based on the Science Citation Index and Social Sciences Citation Index databases. By means of bibliometric tools, this paper provides deep insights on the patterns of these articles, the most influential works and authors, and the emerging research topics. The results imply that China and the United States (USA) are the leading countries in terms of publication output. The Chinese Academy of Sciences is the most productive research institution, followed by Beijing Normal University and the University of Sydney. The Journal of Cleaner Production, Ecological Economics, and Energy Policy are the top mainstream journals in the input–output analysis-related field. Based on network analysis, this paper also discovers the hidden collaboration patterns and interrelations of countries, institutions, and authors. The bibliographic coupling and keywords concurrence networks are adopted to illustrate the input–output analysis evolution over time, and identify the current key research hotspots. The obtained results will help scientific researchers better understand the research status and frontier trends in this field, permit researchers to know the current research interests in the input–output analysis field, and provide useful information for further investigation and publication strategies.
Highlights
The original idea of input–output (IO) theory, which models all of the sectors of the economy via an input–output table, was firstly proposed by Wassily Leontief in the 20th century [1,2]
In this study, the Science Citation Index (SCI) and Sciences Citation Index (SSCI) databases are selected as the data sources for searching for publications related to input–output analysis
Some representations of the input–output model are for energy systems, some are for the input–output structure in neural network systems, some are for input–output in control systems
Summary
The original idea of input–output (IO) theory, which models all of the sectors of the economy via an input–output table, was firstly proposed by Wassily Leontief in the 20th century [1,2]. This great innovation in the economic field earned Leontief a Nobel Prize in 1973 [3]. With the assistance of various statistic indicators and science mapping, this paper will address the following questions: This sketch of the scientific structures would provide new insight into the breadth and depth of this body of knowledge. The obtained results will help scientific researchers better understand the research status and frontier trends in this field, permit researchers to know the current research interests in the input–output analysis field, and provide useful information for further investigation and publication strategy
