Abstract: The construction of a collaborative management model for cross-border online dispute resolution (ODR) in the Guangdong-Hong Kong-Macao Greater Bay Area aims to meet the needs of digital economic transformation and diversified dispute resolution in the Greater Bay Area. By comparing and analyzing the advantages and disadvantages of the US industry autonomy model and the EU government intervention model, combined with the spirit of“prioritizing regional cooperation”, a cross-border collaborative management model that integrates the advantages of government intervention and industry autonomy is proposed. Firstly, although the industry autonomy model can stimulate market innovation vitality, it lacks unified industry norms and credibility; while the government intervention model can provide standardized norms, it may lag behind market demand. Secondly, the Greater Bay Area faces challenges such as a lack of specialized legislation, insufficient public trust in ODR, and incomplete supporting mechanisms, making it difficult to simply adopt the European and American models to solve problems. Furthermore, based on the experiences of Europe and America, the three regions should carry out credibility building through measures such as“transparency procedures”and“institutional certification”, adopt a“dual track system”to manage ODR service providers and unleash institutional innovation power, and use online collaboration platforms to promote online data and resource exchange supporting systems. Finally, the Greater Bay Area should establish a unified ODR industry standard through a joint meeting of the legal departments of the three regions, guide local cross-border collaboration to introduce special legislation, and mobilize dispute resolution institutions in the three regions to jointly build supporting mechanisms, thereby providing institutional innovation experience for national promotion and regional cooperation.
