Core Insights - The article discusses the challenges faced in cross-border medical development, including uneven distribution of medical resources, fragmented cross-border medical information, and obstacles in medical research collaboration [1][2]. Group 1: Cross-Border Medical Data Space - The "Guangdong-Hong Kong-Macao Greater Bay Area Medical Cross-Border Data Space" has been successfully implemented in Nansha, aiming to address the pain points of medical integration among the three regions [2]. - This data space utilizes data contracts and control technologies to automate and engineer the differentiated regulatory systems in the medical data field, establishing a tiered authorization mechanism for data operations [2]. - The platform can transmit over 500TB of high-quality medical data, significantly reducing redundant examinations and shortening consultation times for patients seeking cross-border medical services [2]. Group 2: Collaborative Research and Standards - The data space collaborates with universities in the Greater Bay Area and research institutions in Beijing to build a cross-border AI model fine-tuning platform, which lowers research costs and enhances collaboration efficiency [3]. - An international standard for cross-border data space, IEEE P1988, has been initiated to focus on secure data flow and trusted interactions across organizations and regions, aiming to create a new order for global data cooperation [3]. Group 3: Data Flow Mechanisms and Policies - Nansha has established various platforms for data protection and cross-border services, contributing to the innovative model for data flow mechanisms in the Greater Bay Area [4]. - The "Establishing Cross-Border Data Flow Mechanism in Guangdong-Hong Kong-Macao" has been recognized as a replicable practice for national data element security and efficient cross-border flow [4]. - Nansha is positioned as a core hub for global data flow, supported by policies that encourage compliant cross-border data movement, including subsidies for software and information technology service enterprises [4]. Group 4: Financial Support and Digital Economy - The implementation plan for financial support in Nansha emphasizes the development of a cross-border digital asset recognition system and pilot projects to facilitate internal data flow among banks with branches in Hong Kong and Macau [5]. - Nansha's strategy of "Five Ports Linkage" aims to establish itself as an "International Data Port," enhancing its role in digital economic reform and cross-border data flow [5].
