Abstract: The concept of sustainable development has permeated the world, with citizens, businesses and governments uniting under the SDGs to tackle environmental issues such as the climate crisis. However, the intensification of natural disasters caused by climate change continues, while environmental destruction and widening income disparities driven by globalisation also advance. Consequently, the prospects for coordinated environmental measures between developed and developing nations are becoming increasingly uncertain. The forthcoming Society 5.0, driven by digitalisation, big data, and AI, holds promise for reconciling economic development with social challenges, while also harbouring potential to contribute to solving environmental problems. These cutting-edge technologies may offer new perspectives on long-debated environmental economics concepts: the environmental Kuznets curve, the resource curse, Porter's hypothesis, the pollution haven hypothesis, and income inequality. This review prioritises papers with high citation counts in influential journals from 2015 to 2025 to outline research trends and present future challenges. Through a narrative and literature-based review, it aims to grasp how digitalisation, big data, and AI are altering existing prominent hypotheses, thereby providing direction for theoretical research and social practice.
Keywords: Digitalisation, Big Data, AI, Environmental Kuznets Curve, Resource Curse, Porter Hypothesis, Pollution Escape Hypothesis, Income Inequality.
Biography: Dr.Yoshihiro Hamaguchi received his PhD from Osaka University in March 2020 and currently serves as Professor of Macroeconomics at Hannan University, Osaka, Japan. His research aims to identify the mechanisms of sustainable development, utilising macroeconomic theories of economic growth and analytical methods from international and political economics. His research to date has elucidated how environmental policies can lead to pollution reduction and economic growth through innovation and he has applied his findings to the pollution haven hypothesis, sustainable tourism and sustainable finance. He has received several research grants from the Japan Society for the Promotion of Science (JSPS), reported his research at numerous peer-reviewed international conferences and published in the Journal of Macroeconomics, Tourism Economics, Transport Policy, Frontiers in Marine Science, China & World Economy, Environment, Development and Sustainability, Journal of Environmental Management, among others. Some of these papers were commended for obtaining the highest number of citations in a year. He is currently actively pursuing collaborative research with researchers around the world.
