The Synergistic Impact of Financial Technology and ICT on Load Capacity Optimization in the United States

This research analyses the influence of financial technology (fintech) and the digital economy (DGE) on environmental sustainability in the United States over the period from 1990 to 2021, using the load capacity curve (LCC) hypothesis as a theoretical framework. The primary objective is to assess how technological advancements in financial services and digital infrastructure influence the load capacity factor (LCF), a key indicator of ecological longevity. The analysis employs several econometric approaches, including autoregressive distributive lag model estimation, fully modified ordinary least squares (OLS), dynamic OLS, and canonical cointegrating regression, to explore both short- and long-run relationships between the factors. The outcomes reveal that gross domestic product (GDP) has a substantial negative link with LCF, confirming the U-shaped relationship described by the LCC hypothesis, where higher economic growth initially reduces sustainability but eventually improves it as a country’s development progresses. GDP squared shows a positive impact on LCF, further validating the LCC hypothesis. Moreover, the study demonstrates that fintech and the DGE favorably promote ecosystem health. A 1% increase in fintech activity significantly raises LCF in both the short and long run, indicating that monetary technological innovations contribute to more sustainable economic practices. Similarly, DGE development has an encouraging implication on LCF, suggesting that digital infrastructure facilitates long-term prosperity. Conversely, urbanization negatively affects LCF, highlighting the environmental challenges associated with rapid urban growth. Overall, the study underscores the relevance of integrating growing economies, technological innovation, and urban development to promote long-term environmental sustainability in an increasingly DGE.
