Abstract:The level of legalization of scientific and technological ethical governance is to meet the needs of principled and procedural regulations on the "upstream" of scientific and technological research and development and design. It can delineate boundaries for scientific and technological activities, effectively respond to and regulate behaviors related to scientific and technological applications, and is conducive to promoting responsible scientific and technological innovation and application. Therefore, when solving the Ethical dilemma faced in the process of scientific and technological development, we should explore and reflect on the ethical governance of science and technology in the process of legal construction. This article is based on the correlation between legal governance and technological governance, drawing on past experience and using legalization as the entry point. Starting from the perspectives of substantive rights and obligations, and the construction of a multi-level normative system, effective methods and measures are taken to further improve the mechanism of technological ethical governance and enhance the effectiveness of ethical governance.
