Abstract: Today, the digital economy has become a new engine for high-quality development, and the efficient and trusted circulation of data as a factor is crucial for driving the upgrading of the industrial chain. By integrating key technologies such as blockchain, privacy computing, and smart contracts, trustworthy data space can achieve triple effects of technological, informational, and stakeholder collaboration effectively overcoming the challenges of industrial chain coordination. Therefore, to overcome the bottleneck in data circulation and to drive industrial chains toward a higher-level transition of networking, intelligence, and ecology, future efforts must focus on building a solid infrastructure foundation, deepening data integration and value operations, fostering an open and collaborative industrial ecosystem, and improving institutional systems of standards and regulations. Through these systematic practical pathways, trustworthy data space can be ensured as strategic pivots for cultivating new quality productive forces and supporting the construction of a modern industrial system.

Key words: trustworthy data space, industrial chain upgrade, synergy effect, digital economy, data element, new quality productivity
