Trends and Insights in Green Investment Research: A Bibliometric Study
Abstract
The increasing reality of climate change demands cross-sectoral solutions, including from the
economic, business, and financial sectors. In response to this challenge, adopting more sustainable
practices has become crucial. Companies and industries are directing their investments toward green
technologies that can reduce carbon emissions and improve resource efficiency. Investment flows
are also shifting toward more environmentally friendly sectors, driving the growth of the concept of
green investment. This study aims to map the development of research on green investment using a
bibliometric approach. Data were obtained from the Scopus database and analyzed using VOSviewer
software to evaluate publication trends, author collaboration, country distribution, and keyword cooccurrence. The analysis results show that publications related to green investment have increased
significantly over the past five years. Keywords such as economic policy uncertainty (EPU) and
investment decision are among the most frequently associated with green investment, reflecting
academic attention on the relationship between economic uncertainty and sustainable investment
decision-making. China emerges as the leading country in terms of publication volume, funding, and
affiliated institutions, highlighting its role in the development of green investment literature and
practices at the global level. These findings offer valuable insights for researchers and policymakers
to inform future research directions and enhance policy initiatives that support the transition toward
a green economy.
