Proxy variables of digital financial inclusion.

His research investigates the interplay among investment in Information and Communication Technology [ICT], digital financial inclusion, environmental tax policies, and their impact on the progression of sustainable energy development within the Middle East and North Africa [MENA] region. Recognizing the distinctive hurdles impeding sustainable energy advancement, effective policy formulation and implementation in MENA necessitate a comprehensive understanding of these variables. Employing a Dynamic Common Correlated Effects [DCE] model alongside an instrumental variable-adjusted DCE approach, this study explores the relationship between ICT investment, digital financial inclusion, environmental tax, and sustainable energy development. The DCE model facilitates the analysis of dynamic effects and potential correlations, while the instrumental variable-adjusted DCE model addresses issues pertaining to endogeneity. The results indicate that both ICT investment and the promotion of digital financial inclusion significantly and positively impact sustainable energy development in the MENA region. Additionally, the study underscores the importance of environmental tax implementation in fostering sustainable energy advancement, highlighting the critical role of environmental policy interventions. Based on these findings, governmental prioritization of ICT investment and initiatives for digital financial service integration is recommended to bolster sustainable energy growth in MENA. Furthermore, the adoption of efficient environmental tax measures is essential to incentivize sustainable energy practices and mitigate environmental degradation. These policy recommendations aim to create a conducive environment for sustainable energy progression in the MENA region, contributing to both economic prosperity and environmental conservation.本研究探讨了信息与通信技术（Information and Communication Technology，简称ICT）投资、数字普惠金融、环境税收政策之间的交互作用，以及这些因素对中东与北非（Middle East and North Africa，简称MENA）地区可持续能源发展进程的影响。鉴于可持续能源发展面临独特阻碍，中东与北非地区要制定并实施有效的政策，就需要全面厘清这些影响因素的作用逻辑。本研究采用动态共同相关效应（Dynamic Common Correlated Effects，简称DCE）模型与工具变量调整型DCE方法，探究了ICT投资、数字普惠金融、环境税收与可持续能源发展之间的关联。DCE模型可实现动态效应与潜在相关性的分析，而工具变量调整型DCE模型则能够有效解决内生性相关问题。研究结果显示，ICT投资与数字普惠金融推广均对中东与北非地区的可持续能源发展产生显著正向影响。此外，本研究强调了落实环境税收对推动可持续能源发展的重要意义，凸显了环境政策干预的关键作用。基于上述研究发现，建议中东与北非地区的政府优先推进ICT投资，并出台数字金融服务融合相关举措，以助力可持续能源增长。此外，推行高效的环境税收措施，对于激励可持续能源实践、减缓环境退化至关重要。上述政策建议旨在为中东与北非地区的可持续能源发展营造有利环境，同时兼顾经济繁荣与环境保护双重目标。
