Core Insights - The research led by Professor Xu Xin from Tsinghua University addresses the challenge of measuring the social value created by free digital products and services in the digital economy [2][4]. Group 1: Research Framework and Methodology - The "GDP-B" (Gross Domestic Product-Benefit) measurement method has been introduced to fill the gap in measuring digital welfare, combining empirical research and experimental design to create a scientific measurement system [5][7]. - The GDP-B method balances objective price data and subjective survey data, making intangible digital welfare measurable and comparable [7]. Group 2: Findings from the Research - A large-scale pre-survey covering 13,000 respondents across 11 cities in China revealed that consumers perceive a significantly higher value from digital services compared to international counterparts [8]. - The research indicates that digital welfare is dynamic and varies with usage scenarios and service states, suggesting a need for a more nuanced understanding of digital value [8]. Group 3: Economic Insights and Future Research - The study explores the relationship between digital welfare and economic development, raising questions about the unique shape of China's "digital Kuznets curve" compared to findings from other countries [9]. - A continuous research plan is proposed to establish a dynamic database on digital welfare in China, aiming to provide a solid empirical foundation for understanding the development patterns of the digital economy [9][10]. Group 4: Collaborative Efforts and Future Directions - The research aims to create a long-term observation system for digital welfare in collaboration with organizations like Tencent, providing scientific evidence for policy-making in the digital economy [10]. - Plans include opening research data for broader academic exploration and developing intelligent economic models based on large-scale empirical data [12].
