Since human society entered the information age, the rapid development and widespread application of digital technology have led to the digital economy. Different from the agricultural economy of the farming era and the industrial economy of the industrial era, the digital economy is a new economy, new kinetic energy, and new business model, and has triggered a profound overall change in society and the economy. At this stage, digital technologies, goods and services are not only accelerating the penetration of traditional industries in multiple directions, multiple levels and multiple chains, that is, industry digitization, but also promoting the continuous development and growth of digital industrial chains and industrial clusters, that is, digital industrialization.
At present, the digital economy has become a new engine driving China's economy to achieve good and fast growth, and the various new business models spawned by the digital economy will also become a new important growth point for China's economy. In order to provide better support for the innovative development of the digital economy, my country issued the "Reference Table of Digital Economy Core Industry Classification and International Patent Classification (2023)" in March 2023. This document compares the international patent classification with the digital economy core industry classification, covers the patents related to the digital economy core industries to the greatest extent, and also provides a clearer and more accurate database construction basis for the construction of relevant patent databases.
CnOpenDatais based on the above standards as a database construction guidance document, matched with the list of A-share listed companies and subsidiaries, and provides quantitative statistics on digital economy patents of A-share listed companies. This datais structurally divided into two parts according to patent types: patent application and patent authorization, showing various statistical information of various types of patents, and providing high-quality and advanced digital economy thematic data support for the academic community. It is worth noting that this data counts digital economy patents to the most detailed subcategories.
