在数字经济深刻改变社会生活方式的今天，一项关键的研究挑战摆在学界面前：那些免费的、零价格数字产品和服务，究竟创造了多少社会价值？清华大 学经济管理学院徐心教授领衔的研究团队，经过一年多的系统性探索，提出了创新的解决方案。 在12月3日举办的2025可持续社会价值创新大会（S大会）"前沿研究"分论坛上，徐心教授代表团队首次公开报告了"数字福祉测度研究"的阶段性成果，展 现了中国学者在这一前沿领域的开创性探索。 从"科技向善"实践出发 重新定义数字经济时代价值内涵 这一设问背后，体现的是徐心教授对数字经济时代价值本质的深刻洞察。在他看来，当价格信号在数字领域逐渐失灵时，学术界需要构建新的框架来理解 价值创造的本质。 GDP-B新框架填补数字福祉测量空白 在徐心教授的带领下，研究团队开展了覆盖全国11个一二线城市、13000名受访者的大规模预调研。这些实证研究得出了具有启发意义的发现：首先，研 究显示中国消费者对数字服务的价值感知显著较高。支付、导航等常用APP的月均估值远超国际同类产品水平。"这表明数字技术在中国产生了深度的社 会融合和价值创造。"其次，团队发现了数字福祉的动态变化特征。徐心教授特别指出："我们发 ...

Core Viewpoint - The article discusses the innovative research led by Professor Xu Xin from Tsinghua University, focusing on measuring the social value created by free digital products and services in the context of the digital economy [2][5]. Group 1: Research Background and Motivation - Professor Xu Xin emphasizes the need to scientifically measure the social value of free digital products, such as AR glasses that help hearing-impaired individuals, which significantly enhance their learning and workplace integration [5][6]. - The research aims to redefine the essence of value in the digital economy, especially as traditional price signals become less relevant [5][6]. Group 2: Methodology and Framework - The research introduces the "GDP-B" (Gross Domestic Product-Benefit) measurement method, which combines empirical research and experimental design to create a scientific measurement system for digital welfare [7][9]. - This method aims to balance objective price data and subjective survey data, making the intangible digital welfare measurable and comparable [9][10]. Group 3: Findings and Insights - A large-scale pre-survey involving 13,000 respondents across 11 cities revealed that Chinese consumers have a significantly higher perception of value from digital services compared to international counterparts [10][11]. - The research also indicates that digital welfare is dynamic, changing with usage scenarios and service states, suggesting a need for a more nuanced understanding of digital value [11][12]. Group 4: Future Research Directions - The research team plans to conduct quarterly nationwide surveys to establish a dynamic database on digital welfare in China, aiming to uncover underlying patterns and relationships with economic development [14][15]. - The study seeks to provide a scientific basis for policy-making in the digital economy, collaborating with organizations like Tencent to create a long-term observation system for digital welfare [15][17]. Group 5: Broader Implications - The research not only contributes to academic theory but also aims to enhance the understanding of social value in the digital economy, highlighting the importance of measuring digital welfare for high-quality development [15][17]. - The initiative is expected to foster a research ecosystem that supports data openness and the development of intelligent economic models, addressing deeper questions about value creation in the digital age [17].
