The purpose of this paper is to prove that the current CSAP acts as an entry regulation, increasing the opportunity cost in the national socio-economic environment. To this end, the socio-economic benefits that arise from improving CSAP were evaluated and measured. In particular, it was intended to confirm the practical benefits of opening to global cloud service providers (CSPs) in the public and medical fields. The socio-economic benefits of introducing cloud services in the public and medical sectors were evaluated and measured in terms of flexibility & cost efficiency, stability, service diversity, and innovation. As a result of evaluation and measurement, the total socio-economic benefit that would occur when cloud services were introduced in the public and medical fields was 4,197 billion won + 2ɑ. However, there were no theoretical studies or practical examples of related indicators in the analysis of the socioeconomic benefits of introducing cloud services in the public and medical fields, so a proxy had to be used. As a result, there remains a limitation that there is inevitably an error in estimating benefits. Nevertheless, this study is significant in that it attempted to estimate the quantitative effect in the absence of studies related to the socio-economic benefit analysis of the introduction of cloud services in the public and medical sectors. In addition, this study shows that the current CSAP is acting as an entry regulation for global CSPs, resulting in socio-economic opportunity costs.
