Since the reform and opening-up, China's industrialization has advanced rapidly. However, this high-growth trajectory has been accompanied by challenges such as resource waste and environmental degradation. Against the backdrop of increasingly prominent environmental issues, China's new green development concept has profoundly influenced industrial progress. In recent years, significant achievements have been made: according to the Ministry of Industry and Information Technology's 2020 report on industrial green development (2016-2019), energy consumption per unit of industrial value-added of enterprises above designated size decreased cumulatively by over 15%, equivalent to saving 480 million tons of standard coal and reducing energy costs by approximately 400 billion CNY. Concurrently, carbon dioxide emissions per unit of industrial value-added decreased cumulatively by 18%. The dual objectives of economic and environmental benefits represent the goal of modern industrial development.
Made in China 2025 outlines fundamental principles and major tasks, including innovation-driven development, green manufacturing, intelligent manufacturing, and industrial foundation strengthening. As the primary carrier of the real economy, the green transformation of industry holds immense significance. To consolidate current achievements, technological innovation serves as a crucial focal point.
Consequently, the CnOpenData team has matched Chinese industrial enterprises' patent citation data with green patent innovation data, establishing the China Industrial Enterprises Green Patent Citation and Cited Database. The structural distinction between this database and the Listed Companies Green Patent Citation and Cited Database lies in the integration of the "Green Patent Category Table" from the latter into the "Basic Information Table" of the former, enabling direct access to green patent category information within the Basic Information Table.
Structurally, each table in this database is categorized into three types: Invention Publication, Invention Authorization, and Utility Model (no green patents exist for Designs). Within these broad categories, detailed tables are further divided into: Basic Information Table, Patent Citation Table, Patent Cited Table, and Patent Transaction Information Table for Chinese Industrial Enterprises. Notably, this database introduces a "Textual Data" module, containing patent abstracts for Invention Publications, Invention Authorizations, and Utility Models, providing a robust supplement to the green patent data of industrial enterprises.
Time Coverage
- Invention Publications: Based on application publication date (1985-2021)
- Invention Authorizations / Utility Models / Designs: Based on authorization publication date (1985-2021)
