"Lucid waters and lush mountains are invaluable assets." In recent decades, rapid economic growth has led to excessive resource exploitation, causing severe environmental damage. Against the backdrop of heightened global environmental awareness, nations worldwide have successively proposed sustainable development concepts centered on green initiatives. Within this context, A-share listed companies—as primary entities in China's capital markets—have incorporated green innovation into their strategic planning.
While technological progress may exacerbate environmental pollution, it can also serve as a crucial tool for addressing such challenges. Patent innovation should not solely drive economic development but must integrate environmental protection and sustainable development principles to advance social progress and foster a healthy, green economic ecosystem.
Accordingly, CnOpenData presents the Green Patent and Citation Data of A-Share Listed Companies. Distinct from datasets covering all patents filed by Chinese legal entities and individuals, this database uniquely:
provides comprehensive green patent information, including basic details, transactional data, and citation relationships, focusing on A-share listed companies. Crucially, it encompasses not only the companies themselves but also their subsidiaries, joint ventures, and associates.
Structurally, this dataset divides patent quantity and quality statistics based on patent applications and grants. The quality statistics are further subdivided by patent type into application and grant modules. Each module categorizes patents into green invention patents and green utility model patents, with additional classifications by primary and first-level subcategories.
The detailed tables uniformly feature four sections:
- Invention Application
- Invention Grant
- Utility Model Application
- Utility Model Grant
Each section displays basic information, citation records, citations received, and transactional data for respective patent types, all identified by unique green patent numbers. Note: Design patents are excluded from green patent classifications.
Time Coverage
- Invention Applications: Statistics based on application publication dates (1990–2024)
- Invention Grants/Utility Models/Designs: Statistics based on grant publication dates (1990–2024)
