Since the existing regulatory improvement mainly aims to amend laws or to reorganize governance, it often fails to reflect the perceptions of the stakeholder’s, involved in the regulatory improvement process. Therefore, this study is meaningful in that it provided policy implications by identifying the stakeholder’s participating in the regulatory sandbox in order to overcome the limitations of existing studies. First, in the project-type regulatory sandbox, the issues related to evaluation and certification will be the most important factor for law revisions. Second, it is necessary to clearly set the differences between the place-based empirical issues in the project-type and regional-limited regulatory sandbox. Third, in the case of new technology, it is difficult to purchase insurance due to the limitations of insurance. So it need to use deduction system for implementation. Fourth, in the safety verification-related examination procedure, the examination procedure should be simplified. This study suggests that there is a need for a support system that identifies the perception differences of stakeholder’s participating in the regulatory sandbox.
