Since human society entered the information age, the rapid development and widespread application of digital technologies have given rise to the digital economy. Distinct from the agricultural economy of the agrarian era and the industrial economy of the industrial age, the digital economy represents a new economic form, driving force, and business model, triggering profound transformative changes across society and the economy. Currently, digital technologies, products, and services are not only accelerating their penetration into traditional industries through multi-directional, multi-layered, and multi-chain integration—termed industrial digitization—but are also fostering the continuous expansion of digital industrial chains and clusters, known as digital industrialization.
Today, the digital economy has become a new engine driving China's high-quality and rapid economic growth. Various new business models emerging from the digital economy will also serve as crucial growth points for China's economy. To better support the innovative development of the digital economy, China released the Classification of Core Industries in the Digital Economy and Corresponding International Patent Classification Reference Table (2023) in March 2023. This document aligns the International Patent Classification with the classification of core digital economy industries, maximizing coverage of patents related to digital economy core industries while providing a clearer and more accurate foundation for constructing specialized patent databases.
CnOpenData utilizes this standard as the foundational framework and aligns it with the list of A-share listed companies to provide digital economy patent-related data for these firms. Structurally, the dataset categorizes patents into three types: invention disclosures, invention authorizations, and utility models. Each category includes citation tables and cited tables to demonstrate citation relationships, complementing data on digital economy patent applications and authorizations of A-share listed companies. This aims to deliver higher-quality and advanced thematic data support for academic research on the digital economy.
