China’s remarkable progress in recent years has been driven in part by its growing technological prowess. But how do we measure and understand this innovation? Researchers are increasingly turning to patent citations, which can offer valuable insights into the flow of knowledge and the influence of past inventions on new technologies.
This blog post delves into a research paper titled “Technology and Innovation in China: a Patent Citation-based Analysis”. We’ll explore how the study analyzes patent citations granted by the Chinese government’s State Intellectual Property Office (SIPO) between 2008 and 2012 to shed light on China’s innovation landscape.
Background
- Historically, including citations in patent applications wasn’t mandatory until 1997 and even faced temporary setbacks. This means that data on patent citations before this time may be scarce or unreliable.
- The lack of a robust patent citation system in China posed challenges for researchers trying to understand the country’s innovation landscape.
- Scholars previously used data from external patent offices like the United States Patent and Trademark Office (USPTO) to analyze China’s innovation, but this approach has limitations.
- Recent efforts by Chinese authorities are improving the patent citation system, making it a more valuable tool for researchers.
Methodology
The study utilizes patent citation data from the SIPO for the period 2008-2012 and employs various techniques to analyze it:
- Data Collection: The primary data source is Chinese patent citations from the SIPO, covering both inventor citations (citations made by the inventor to previous patents) and examiner citations (citations added by the patent examiner during the review process).
- Bibliometric Analysis: The study uses established techniques to analyze patent citation information.
- Technological Indicators: Key indicators like citations per patent, foreign citation dependence, current impact index, and highly cited patents are employed to assess the technological landscape and innovation patterns.
- Citations per patent (CPP) measures the average number of times a patent is cited by subsequent patents, indicating its influence on future inventions.
- Foreign citation dependence (FCD) evaluates the extent to which Chinese patents rely on foreign citations, reflecting the international connectivity of Chinese innovation.
- Current impact index (CII) assesses the current influence of a patent based on its citations.
- Highly cited patents (HCI) are patents that receive a significantly high number of citations, signifying their exceptional importance and impact in the technological landscape.
- Analysis Framework: The authors analyze both domestic and international patents through inventor and examiner citations to gain a comprehensive understanding of China’s technology development.
By employing these methods, the researchers aim to shed light on the patterns of technological innovation and knowledge diffusion in China during the study period. This can provide valuable insights into the current state and future direction of China’s technological development.
