The objectives pursued by a legal system constitute its core spirit and purpose to be achieved, serving as the compass that directs its enactment, amendment, interpretation, and implementation. While financial digitalization has profoundly reshaped the financial landscape, market failures and inherent features of the financial sector persist and even intensify, the destructive impact of financial risks in financial digitalization on both finance and the real economy increases, and the losses to financial consumers and financial efficiency become increasingly heavy. Consequently, under digital conditions, financial regulation should still prioritize the prevention of financial risks to safeguard financial stability, protect financial consumers, and ensure financial efficiency. However, financial digitalization poses new and severe challenges to these three objectives. Thus, to maintain and fulfill these regulatory objectives in the digital era, it is imperative to develop new legal frameworks or reform existing ones in response to the disruptions caused by financial digitalization. Specifically, regarding financial risk prevention, the compounding effects of non-systemic risks, systemic risks, and cross-border risks newly introduced or exacerbated by financial digitalization combined with the legislative lag severely challenge the regulatory objectives of financial risk governance. Therefore, it is essential to correspondingly integrate institutions such as digital technology enterprises into financial risk regulatory frameworks, implement prudential regulations that balance security and innovation, strengthen international governance of digital financial risks, and enhance institutional constraints on regulatory capacity building. Regarding the protection of financial consumers, digital crimes, information asymmetry amplified by algorithmic black boxes, and the failure of traditional remedies for financial consumers will significantly undermine the interests and confidence of financial consumers in the digital era. Consequently, the law should intensify penalties for digital crimes, increase algorithmic transparency to address black-box challenges, and improve remedies for financial consumers under digital conditions. Regarding the ensurance of financial efficiency , financial digital monopolies, flaws of digital technologies, and data leaks all contribute to efficiency losses. Hence, it is imperative to curb monopolistic practices by BigTech and their platforms to preserve competition, while simultaneously addressing technological vulnerabilities and preventing data leaks to mitigate efficiency erosion.
