专利信息公共服务对企业技术创新的影响研究数据集

Based on the establishment of national level patent information dissemination and utilization bases as a natural experiment, and using data from Shanghai and Shenzhen A-share listed companies from 2008 to 2022, a multi period double difference model is constructed to study the impact and mechanism of patent information public service construction on enterprise technological innovation. The micro level enterprise data is sourced from the Guotai An database, while the macro level data is sourced from historical sources such as the China Statistical Yearbook and the China Urban Statistical Yearbook, as well as relevant data from national patent information dissemination and utilization bases. The author obtained this data by collecting and organizing publicly available information from national and provincial intellectual property offices, news reports, and other online sources.
