“Regulatory sandbox” is an innovative way of financial supervision to promote the development of financial science and technology and alleviate the lag of law. Among them, the exit system, as a closed-loop system of “regulatory sandbox”, is its core content, while the continuous testing of enterprise commitment sys_x005ftem is an important content to improve and enrich the exit system. To build a continuous testing enterprise commitment system, we should first solve the problem of its scope of application. Based on this, China should start from the top-level design, formulate general provisions through legislative control and law enforcement discretion rules, preliminarily regulate the scope of application of the continuous testing of enterprise commitment system, and give the regulatory authority discretion. Secondly, through the negative exclusion and positive application rules, the scope of application of the continuous testing of enterprise commitment system is specifically regulated. Finally, a set of top-down continuous testing enterprise commitment system with good flexibility will be formed, and the rules will be established to limit the scope of application of the continuous testing enterprise commitment system scientifically and perfectly.
