## 2 Literature Review  
Over the last several years, many researchers have focused their attention on the digitalization sector [27]. [PERSON] et al. examines the effect of digitalization on both average and dispersed energy use [28]. Cross-sectional Augmented Autoregressive Distributed Lag (CS-ARDL) is used to assess both the long-run and short-run elasticity of digitalization. The findings indicate that digitization does reduce the overall and dispersed levels of energy use. Thus, if we want to reach our goals for energy sustainability, we should put more money into growing and improving our digital infrastructure. Numerous studies consider the global trend in digital applications for public service, and specifically, the ASEAN countries are one of the most interesting areas, concerning the sustainability of economic, social, and environmental pillars. This is because the ASEAN countries are home to some of the most rapidly developing economies in the world. [PERSON] et al. created a criteria framework for connections in Singapore firms to comprehend how organization-stakeholder interactions may be handled effectively to facilitate an appropriate reformation of business operations [29]. This study investigates in detail an e-government initiative since public agencies frequently adopt new information technology (IT) to simplify and innovate their obsolete processes. The researchers concentrated on the phenomenon of managing e-transformation, especially e-fill systems from 1992 to 2003. In addition, this research was to contribute to the academic and conceptual understanding of e-transformation by examining a variety of difficulties within the enterprise reformative procedures implicated in the implementation of an e-government curriculum. In Vietnam, [PERSON] et al. provided a case study on electronic customs about the digitalization of the public sector [30]. This research confirms that culture is a significant benefit, although finance, human resources and regulation may be obstacles. Currently, Vietnam is not constrained by technical advances. Additionally, administration rules and restrictions are a constraint. The paper's findings provide authorities with crucial ideas for enhancing e-custom operations and aid company executives in formulating plans for adapting to the industrialization environment. [PERSON], [PERSON] focuses on the supervisors of Thailand's major public institutions as he examines Thailand's digital transformation initiatives [31]. The government is pursuing digital transformation plans version 4.0 to enhance company efficiency, human well-being, and public service productivity. This study examinedthe difficulties in sustaining reform administration and responsibilities, regulation, accessibility, staff capacities, and performance evaluation, as well as the efforts of national agencies to solve these issues. The objectives of e-government include increasing the capability to provide improved public services, improving the quality of life for residents, boosting the competence and capability of the corporate sector, and strengthening community health and public safety. The whole ASEAN region will need to improve its internet platform, cultivate more talented individuals with superior technological knowledge, and implement a well-considered legislative authority [32]. Furthermore, for digitalization to work well in ASEAN countries, the public and private sectors need to work together and communicate with each other. From the literature review, it can be concluded that the digitization of public services has not been examined in ASEAN. Considering this, attempts have been made to evaluate this process in the current work. In fact, to the best of the authors' understanding, this is the initial effort to apply MCDM analysis to assess the efficiency of this method. To fill the gap in research, important key criteria were first found through a review of the literature and then confirmed by talking to professionals.
