“星火·链网”国际打造汽车工业数据生态 “信任锚”：中德技术专家组取得阶段成果

在全球汽车产业向智能化、网联化转型新时期，中德两国技术专家正携手构建工业数据交换的 “信任基石”。近日，中德技术专家组撰写《汽车工业数据生态系统“清算所”专家组第一阶段报告》，介绍了中德在汽车工业数据空间互联领域的技术探索成果与未来规划。这份报告标志着中德工业数据生态合作迈出务实步伐，有望为全球工业数据空间提供信任范式。

中德数据生态合作：从共识到落地

当德国汽车工业产业链数字化向具有自主权的数据交换推进过程中遇上中国的新型工业化，数据空间成为两国产业协同的新纽带及可能性。德国联邦经济事务和能源部（BMWE）与中国工业和信息化部（MIIT）支持的中德工业数据生态对话平台项目，正将共识转化为实践试点。

2024 年 9 月，在德国国际合作机构（GIZ）中德工业数据生态系统对话项目的协调下，中国信息通信研究院（以下简称“中国信通院”）与 Catena-X汽车网络协会（以下简称“Catena-X”） 正式成立技术专家组，目标直指核心命题：如何为中国企业参与 Catena-X 数据空间构建本土化的 “信任入口”—— 数字清算所（Digital Clearing House）。这一机制如同数据空间的 “海关”，负责验证企业身份的真实性，确保数据交换在可信环境下进行。

Catena-X则致力于打造覆盖整个汽车产业链的安全数据生态，其愿景是通过统一标准连接车企、供应商与服务商，构建 “可信、协作、开放” 的数据空间。在数据空间中，信任是一切合作的前提。Catena-X 数据空间现有体系中，所有参与者需通过欧洲服务商提供的清算所服务完成身份核验。但对于中国企业而言，本土化的信任验证机制更为关键 —— 这不仅涉及技术适配，更关乎数据自主权与合规要求。

中国信通院能够识别统一社会信用代码、工业互联网标识，并基于“星火・链网”国际（ASTRON）的去中心化身份（DID）与可验证凭证（VC）技术能力，为中国企业提供可信身份认证服务。这种能力恰是连接中德数据生态 “桥梁” ，既满足中国企业的本土合规需求，又能与 Catena-X 的国际标准对接。

专家组首阶段技术验证全过程

传统数据空间往往依赖单一清算所，难以适应全球化场景下的多元信任需求。专家组的首要创新，是设计了支持 “多清算所并行” 的架构 —— 在保留欧洲清算所的同时，新增中国本土清算所节点，以满足跨域、跨信任体系间的互认、互信与高效协作。2024 年 10 月至 2025 年 4 月，中德专家团队开展了为期 7 个月的技术攻坚和数十次的线上线下研讨及试验。实现了中国企业的身份认证体系能与 Catena-X 的 “商业伙伴编号（BPN）” 体系实现语义互操作。这场跨越欧亚大陆的协同创新，不仅验证了技术可行性，更开创了工业数据跨境信任机制的新范式。

2025 年 4 月，当最后一组测试数据通过中国信通院工物所的 “清算所”验证并返回成功信号时，标志着我国在汽车工业数据空间本土化信任节点的技术上实现了零的突破。参与测试的中德专家认为“这次成功不仅是技术的胜利，更是跨文化协作的典范 —— 我们用代码搭建了理解的桥梁。”

生态赋能的 “三步走” 规划

未来，中德技术专家组提出了 “功能强化 - 试点应用 - 生态运营” 的三阶段进阶路线图，每一步都直指产业实际需求。

在功能强化方面，中国信通院与Catena-X将持续加强中德技术专家组的交流，完善清算所的系统升级与功能强化，将工业互联网标识纳入身份认证体系中，将工业数据空间与中国工业互联网体系深度绑定，为后续设备数据、生产数据的跨境流动奠定基础。

在试点应用方面，苏州工业园区的苏州新建元数据科技发展有限公司意向承担清算所角色，在中国信通院的技术支撑下运营本土化清算所服务。同时，Catena-X还计划联合中国汽车工业协会（CAAM）成员企业，开展真实场景下的试点应用。这些试点将聚焦三大方向： 供应链协同：验证零部件供应商数据在中德车企间的可信交换，提升供应链透明度； 碳足迹追踪：通过数据互联实现跨国产业链的碳排放核算，助力 “双碳” 目标落地。

在更宏观的层面，中德技术专家组将继续扮演 “技术翻译官” 角色 —— 一方面将 Catena-X 的国际标准 “中国化”，另一方面将中国工业互联网、可信数据空间的实践经验 “国际化”。这种双向赋能正在产生化学反应： 统一社会信用代码、工业互联网标识与 BPN 的映射关系、国际 DID 体系的兼容方案，正在形成可推广的技术规范；中德技术专家组将把试点经验转化为政策建议，为德国联邦经济与能源部（BMWE）与 中国工业和信息化部（MIIT） 的对话提供技术支撑；通过德国国际合作机构（GIZ） 的平台，中德技术人员将开展常态化交流，培养兼具两国技术背景的 “数据生态架构师”。

Building a Trusted Anchor for the Automotive Industry Data Ecosystem: Sino-German Technical Expert Group Achieves Milestone Results

In the new era of the global automotive industry's transition towards intelligence and connectivity, technical experts from China and Germany are working together to build a ‘trusted foundation’ for industrial data exchange.

Recently, the Sino-German Technical Expert Group published the ‘First Phase Report of the Expert Group on the Automotive Industry Data Ecosystem “Clearing House”’, outlining the technical exploration achievements and future plans of China and Germany in the field of interconnected automotive industry data spaces. This report marks a practical step forward in Sino-German industrial data ecosystem cooperation and is expected to provide a trust model for global industrial data spaces.

Sino-German Data Ecosystem Cooperation: From Consensus to Implementation

As Germany's automotive industry supply chain advances toward digitalisation with sovereign data exchange, it encounters China’s new industrialisation, making the data space a new link and possibility for industrial cooperation between the two countries. The Sino-German Industrial Data Ecosystems project, supported by the German Federal Ministry for Economic Affairs and Energy (BMWE) and the Chinese Ministry of Industry and Information Technology (MIIT), is transforming consensus into practical pilot projects.

In September 2024, under the coordination of the Sino-German Industrial Data Ecosystems project of the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), the China Academy of Information and Communications Technology (CAICT) and the Catena-X Automotive Network Association (Catena-X) officially established a technical expert group. The group's core objective is to address the critical question: How can Chinese enterprises participate in the Catena-X data space by establishing a localised ‘trust entry point’—the Digital Clearing House.

This mechanism acts as a ‘customs’ for the data space, responsible for verifying the authenticity of enterprise identities and ensuring that data exchange occurs in a trusted environment. Catena-X is committed to building a secure data ecosystem covering the entire automotive industry chain. Its vision is to connect automakers, suppliers, and service providers through unified standards, creating a ‘trustworthy, collaborative, and open’ data space. In the data space, trust is the prerequisite for all cooperation.

In the existing Catena-X data space system, all participants must complete identity verification through clearing house services provided by a European service provider. However, for Chinese enterprises, a localised trust verification mechanism is even more critical — this not only involves technical compatibility, but also data sovereignty and compliance requirements.

CAICT can identify unified social credit codes and industrial Internet identifiers, and based on the decentralised identity (DID) and verifiable credential (VC) capabilities of ‘Xinghuo Chain Network’ International (ASTRON), it can provide trusted identity authentication services for Chinese companies. This capability is precisely the ‘bridge’ connecting the Chinese and German data ecosystems, meeting the local compliance needs of Chinese companies while also connecting with Catena-X's international standards.

The entire process of the expert group’s first phase of technical verification

Traditional data spaces often rely on a single clearing house, which is difficult to adapt to the diverse trust requirements of a globalised environment. The expert group's primary innovation was to design an architecture that supports ‘multiple clearing houses in parallel’ — while retaining the European clearing house, a new local clearing house node was added in China to meet the requirements of mutual recognition, mutual trust and efficient collaboration across domains and trust systems. From October 2024 to April 2025, the Chinese and German expert teams conducted seven months of technical research and dozens of online and offline discussions and trials. They achieved semantic interoperability between the identity authentication system of Chinese enterprises and Catena-X’s ‘Business Partner Number (BPN)’ system. This collaborative innovation spanning the Eurasian continent not only validated technical feasibility but also pioneered a new paradigm for cross-border trust mechanisms in industrial data.

In April 2025, when the final set of test data passed verification by the ‘clearing house’ of CAICT and returned a successful signal, it marked a breakthrough in the technical validation of China's localized trust node for automotive industrial data spaces . Chinese and German experts who participated in the testing believe that ‘this success is not only a technical victory, but also a model of cross-cultural collaboration — we have built a bridge of understanding with code.’

Three-step plan for ecosystem empowerment

In the future, the Chinese and German technical expert group has proposed a three-stage roadmap of ‘function enhancement, pilot application, and ecosystem operation,’ with each step directly targeting the actual needs of the industry.

In terms of functional enhancement, CAICT and Catena-X will continue to strengthen exchanges between Chinese and German technical experts, improve the clearing house's system upgrades and functional enhancements, incorporate industrial internet identifiers into the identity authentication system, and deeply bind the industrial data space with China's industrial internet system, laying the foundation for the cross-border flow of equipment data and production data in the future.

In terms of pilot applications, Sungent Data Technology Co., Ltd. in Suzhou Industrial Park intends to assume the role of clearinghouse and operate localised clearinghouse services with the technical support of CAICT. Additionally, Catena-X plans to collaborate with member companies of the China Association of Automobile Manufacturers (CAAM) to conduct pilot applications in real-world scenarios. These pilots will focus on three key areas: Supply Chain Collaboration: Verify the trustworthy exchange of component supplier data between Chinese and German automakers to enhance supply chain transparency; Carbon footprint tracking: Realising cross-border carbon emission accounting through data interconnection to support the implementation of the ‘dual carbon’ goals;

At a more macro level, the Sino-German technical expert group will continue to play the role of ‘technical translator’ — on the one hand, ‘localising’ Catena-X international standards for China, and on the other hand, ‘internationalising’ China’s industrial internet and trusted data space practices. This two-way empowerment is creating a chemical reaction: The mapping relationship between the unified social credit code, industrial internet identifiers, and BPN, as well as compatibility solutions for the international DID system, are forming technical standards that can be promoted; The Sino-German technical expert group will convert pilot experience into policy recommendations to provide technical support for dialogue between BMWE and MIIT; Through the platform of GIZ, Chinese and German technical personnel will engage in regular exchanges to cultivate ‘data ecosystem architects’ with expertise in both countries’ technical backgrounds.
