The comprehensive development of consultative democracy is an imperative requirement for developing whole-process people’s democracy and modernizing China’s governance system and capacity. Since the emergence of information technology, consultative democracy has experienced four stages of development: electronic, networked, digital, and intelligent. In the process of Digital China construction, the strategic task of “comprehensive development of consultative democracy”, the practical need to improve the efficiency of consultative governance, and the innovative exploration of the digitally-empowered consultative practices constitute the digital-intelligent transformation of consultative democracy. Through the enabling mechanism of “environment optimization–subject activation–mechanism innovation–efficiency improvement–culture cultivation”, digital intelligence technology creates preconditions for the comprehensive development of consultative democracy by constructing digital negotiation space and cooperative environment, and activates the internal drive of participants through structural restructuring, consciousness enhancement, and skill cultivation. The consultative process is refined through innovation and operational mechanisms such as agenda setting, process management, risk assessment, and intelligent adjustment. Digital intelligence technology promotes good governance through consultation by improving the efficiency of consultation results transformation, implementation and supervision, and enables high-quality development of consultative democracy through digital intelligence consultation culture cultivation and value dissemination. At the same time, the development of digital intelligence empowerment also faces risks and challenges such as increased difficulties in governing public opinion and protecting information security, conflicts between technological integration and democratic values, inadequate development of computing infrastructure and consultative channels, and risks of technological manipulation and platform detachment. In practice, to promote the comprehensive development of consultative democracy enabled by digital intelligence technology, it is necessary to deepen the integration of digital intelligence technology and various consultative channels based on accelerating the construction of digital intelligence infrastructure and cultivating the digital intelligence literacy of multiple subjects, improve the balance of enabling, strengthen the institutional mechanism and legal guarantee, and lead digital intelligence empowerment toward socially responsible outcomes through value-driven logic and a people-centered approach.
