Dalian Sunshine Procurement Service Co., Ltd. (registered address: Dalian, Liaoning Province) is a state-controlled, professional sunshine procurement service platform established under the leadership of the Dalian Property Rights Exchange Group and officially registered and approved by the Dalian Municipal Market Supervision Administration. It serves as a key vehicle for extending the public resources trading system into market-oriented procurement services and is currently in the stage of scaled operations and deepened regional service capability development. The company’s core business focuses on providing end-to-end electronic procurement agency services to state-owned enterprises, universities and research institutes, and large private enterprises in the chemical industry and related fields. Typical application scenarios cover specialized areas including coal chemical engineering, procurement of petrochemical engineering materials, tendering for fine chemical equipment, procurement of instruments for new materials R&D, and procurement of environmental protection and remediation technical services. Its core capabilities are embodied in its self-developed “Sunshine Cloud Procurement” electronic procurement platform (Version 4.2.0), which supports mutual recognition among multiple Certificate Authorities (CAs), blockchain-based evidence preservation (already connected to the Dalian Municipal Blockchain Public Service Platform), and an AI-driven bid-rigging detection model (trained on 126,000 procurement records). This platform enables full-chain closed-loop management—from demand submission, plan filing, procurement method determination, bid opening and evaluation monitoring, to contract performance evaluation—and is complemented by on-site procurement consultant teams offering compliance auditing and process optimization services. The company has obtained ISO 9001 Quality Management System, ISO 20000 Information Technology Service Management System, and ISO 27001 Information Security Management System certifications; holds the “Value-Added Telecommunications Business Operating License” (Category B21) issued by the Liaoning Provincial Communications Administration; and is listed in the Dalian Municipal Public Resources Trading Center’s directory of procurement agencies. Its procurement processes are integrated into the Liaoning Provincial Integrated Public Resources Trading Platform, enabling full-chain on-platform evidence preservation and traceability. Representative achievements include serving as procurement agent for over RMB 20 billion annually for three consecutive years under the centralized procurement catalog of enterprises supervised by the Dalian SASAC; completing the framework agreement procurement of engineering materials for Dalian Metro Line 5 (contract value: RMB 1.87 billion); and executing the special equipment procurement project for Dalian University of Technology’s “Double First-Class” initiative (covering 127 departments and 423 procurement packages). Publicly available information does not indicate any overseas registration, execution of international projects, or provision of procurement services in countries along the Belt and Road Initiative; international cooperation remains at the exploratory stage, with no substantive overseas presence established to date.
