Taxation serves as the fundamental cornerstone supporting the long-term development of a nation. As a crucial foundational task for facilitating fiscal reforms and strengthening tax administration, the national tax survey provides robust data support for tax policy formulation. Simultaneously, it plays a vital role in enabling scholars to accurately grasp tax source conditions and observe economic development trends.
Enterprises participating in the national tax survey are categorized into sampled and key enterprises. Sampled enterprises are further divided into national tax sampled enterprises and local tax sampled enterprises, while key enterprises are classified as national tax key enterprises and local tax key enterprises. These enterprises demonstrate significant representativeness among all Chinese taxpayers, sufficient to characterize and analyze the tax payment status of the entire enterprise population.
It should be noted that although the tax survey enterprise data covers 2008-2015, we have intentionally matched it with all patent data through 2022. This approach primarily addresses the inherent lag in patent citation data, ensuring relatively complete coverage of patent citation information through extended temporal matching.
Structurally, this dataset comprises three components: Patent Quantity Statistics Table, Patent Quality Statistics Table, and Patent Details Table. The quantity and quality statistics are further subdivided based on patent applications and grants respectively. The quality statistics are additionally categorized by patent type into three modules: invention, utility model, and design. Citation and cited information are presented in the Patent Details Table, divided into four modules: invention applications, invention grants, utility models, and designs. Each module contains four sub-tables: Basic Information Table, Citation Table, Cited Table, and Transaction Table (note: design patents lack citation tables).
Temporal Coverage
- Invention disclosures: Statistics based on application publication dates (1985-2022)
- Invention grants/Utility models/Designs: Statistics based on grant publication dates (1985-2022)
