The energy consumption-environmental quality nexus in BRICS countries: the role of outward foreign direct investment

Towards environmental degradation mitigation: The role of regulatory quality, technological innovation and government effectiveness in the CEMAC countries

The study explores the interaction between regulatory quality, economic growth, technological innovation, energy consumption, government spending on research and development, and environmental degradation (EVD) in the Economic and Monetary Community of Central Africa (CEMAC) region. The study applied the econometric approach CS-ARDL to estimate the short and long-term interaction between the regressors and the explanatory variable. The study period covers from 1990 to 2020. To summarize the findings of this research, (1) the study discovered a positive relationship between energy consumption, government effectiveness, regulatory quality, and environmental degradation. (2) Economic growth, government spending on research and development, and technological innovation, on the other hand, extensively dissipates EVD in the CEMAC economies. (3) The causality analysis espoused a bidirectional connection between energy consumption, technological innovation, and EVD. (4) Lastly, a unidirectional interplay exists between economic growth, government effectiveness, regulatory quality, and EVD. This study also serves as a reference point for policymakers and governmental institutions to invest in cleaner technologies and increase government research and development spending to mitigate environmental degradation in these areas.

An empirical assessment of the tripartite nexus between environmental pollution, economic growth, and agricultural production in Sub-Saharan African countries

A lot of attention has been paid to environmental pollution worldwide, due to the increase in anthropogenic activities. Massive investment in non-renewable energy options raises questions regarding environmental sustainability and how to maximize food and non-food output while still preserving a healthy ecosystem. To this end, the present study explores the three-way nexus between economic growth, CO₂ emission, and agriculture-value added will accounting for other control variables across a balanced panel of selected African economies from 1997 to 2020. Panel econometrics method of the generalized method of moments (two-step difference GMM) is used to obtain a robust result. From the present study, the environmental pollution model shows that economic growth significantly contributes to environmental pollution in Africa. Additionally, the food price index, capital, and FDI promote pollution, while agricultural production and labor decrease pollution. In the case of the economic growth model, the findings reveal that environmental pollution supports the growth-led pollution hypothesis. Also, the food price index and capital ameliorate economic growth, while foreign direct investments decrease economic growth. Finally, the agricultural production model indicates that economic growth increases agricultural production when the interaction term between GDPC and FDI is included in the model. In summary, the combination of explanatory variables, environmental pollution, capital, and foreign direct investment decreases agricultural production. On the contrary, the food price index and labor promote agricultural production in Africa. Furthermore, the study provides a lot of policies for authorities and stakeholders in Sub-Saharan African countries and other developing economies.

Dissipating environmental pollution in the BRICS economies: do urbanization, globalization, energy innovation, and financial development matter?

The question of how Brazil, Russia, India, China, and South Africa (BRICS countries) can substantially dissipate environmental pollution (EVP) remains unsolved. In this regard, this research explores the dynamic association between energy consumption (EGC), economic expansion (EXP), globalization (GLO), energy innovation (ENI), urbanization (URB), financial development (FID), and environmental pollution (EVP) using panel data from 1990 to 2020. This study integrated the augmented mean group (AMG), common correlated effect means group estimator (CC-MG), and fully modified ordinary least square (FMOLS) model approach to estimate the long-run interaction among the series. The findings of this study reveal a positive and significant association between economic expansion, energy consumption, urbanization, financial development, and environmental pollution. In contrast, globalization and energy innovation extensively abate EVP in the BRICS economies. Moreover, the outcome of the Granger causality test indicates that energy consumption and energy innovation have a bidirectional association with EVP. The Granger causality test further revealed a unidirectional causality between globalization, urbanization, financial development, and environmental pollution. Finally, this research has implications for policymakers in the BRICS countries.

A Bibliometric Review of Energy Related International Investment Based on an Evolutionary Perspective

Energy security could be jointly maintained through the cooperation of different countries or regions. In this circumstance, there has been a large number of energy-related international investment studies. However, the existing academic literature lacks a systematic scientometric analysis of this research topic, so this paper will fill this gap. Using CiteSpace, VOSviewer, and HisCite, this paper analyzes 1014 articles published in the WoS SSCI Collection from January 1998 to March 2022 on the energy-related international investment. This paper comprehensively analyzes this field from four evolutionary dimensions. In the discipline and mainstream journals dimension, the largest change lies in the fact that more than three different disciplines flow into mathematics, while the journal “Environmental Science and Pollution Research” shows a dramatic growth in relevant publications after 2015. Keyword evolution shows a gradual deepening emphasis from attracting energy-related international investment to systematically analyzing the influencing mechanisms of the international investment-energy-environmental quality nexus. Citation clusters identifies two latest clusters, including institutional quality and renewable energy consumption. Citation paths summarize four major evolutionary paths. The overall evolution trend is based on the FDI-energy-environment nexus, and gradually considers the influence mechanism of different factors on this nexus.
