Research on the Collaborative Innovation Network of Chinese Patent Medicine Patents in the Guangdong-Hong Kong-Macao Greater Bay Area Based on SNA Method
This study employs social network analysis and quadratic assignment procedure on 2016–2024 patent data to reveal that the Guangdong-Hong Kong-Macao Greater Bay Area's Chinese patent medicine innovation network exhibits a core-periphery structure centered on Guangzhou and leading institutions, has evolved toward multi-stakeholder collaboration with increasing cross-border integration since 2021, and is significantly driven by geographical and technological proximity.

The Big Picture: A "Team-Up" Map for Herbal Medicine Patents
Imagine the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) as a massive, bustling construction site dedicated to building Chinese Patent Medicines (traditional herbal remedies). The researchers wanted to know: Who is working together on these projects, and how well are they coordinating?
To find out, they looked at patent data (the official blueprints for new medicines) from 2016 to 2024. Instead of just counting how many blueprints were filed, they used a method called Social Network Analysis (SNA). Think of this as drawing a giant map where every company, university, or government office is a dot, and every time they work together on a patent, they draw a string connecting the dots.
The Main Findings: What the Map Revealed
1. The "Island" Problem (Low Density)
The map showed that while there are thousands of dots (innovators), most of them are floating alone.
- The Analogy: Imagine a party where hundreds of people are in the room, but 90% of them are standing in corners talking to themselves. Only a few small groups are actually chatting and sharing ideas.
- The Reality: Most patent applications are done independently. Very few companies or universities are actually collaborating. The "strings" connecting the dots are very few, making the network "loose" and "fragmented."
2. The "Super-Hub" City (Guangzhou)
The map revealed a clear Core-Periphery structure.
- The Analogy: Think of the network as a solar system. Guangzhou is the Sun. It is the absolute center, holding the most connections. Shenzhen, Foshan, and Hong Kong are like the inner planets—they have their own gravity but orbit the Sun. The other cities (like Dongguan or Macao) are like distant asteroids, barely connected to the main system.
- The Reality: Guangzhou is the undisputed leader. It has the most universities and companies working together. While other cities are trying to join in, they are mostly working in isolation or only talking to Guangzhou, not to each other.
3. The "Who's Who" (The Players)
- The Players: The main characters are Universities (the scientists), Companies (the manufacturers), Research Institutes (the specialized labs), and Government (the rule-makers).
- The Shift: In the early years (2016–2020), it was mostly companies working alone or with one university. By the later years (2021–2024), the team got bigger. Universities, research labs, and the government started joining the party more often. It's evolving from a "lone wolf" strategy to a "team sport."
- The Stars: South China Agricultural University and Guangdong Pharmaceutical University are the "MVPs" (Most Valuable Players) of this network. They have the most connections and act as the main bridges between different groups.
4. Why Do They Team Up? (The Two "Proximities")
The researchers asked: What makes two people decide to work together? They tested two main theories:
- Geographical Proximity (Being Neighbors): "If we live in the same city, it's easier to grab coffee and sign a deal."
- Result: YES. This is the strongest factor. People in the same city (especially Guangzhou) are much more likely to collaborate.
- Technological Proximity (Speaking the Same Language): "If we both study the same type of herbs, we understand each other better."
- Result: YES, but weaker. If two groups work on similar technologies, they are more likely to collaborate, but this matters less than just being in the same city.
The Timeline: How Things Changed
The study split the data into two eras:
- Era 1 (2016–2020): Small teams, mostly companies, very isolated.
- Era 2 (2021–2024): The network exploded in size. More universities and the government joined. Hong Kong and Macao started moving from the "edge of the room" to the "dance floor," though they are still not fully integrated into the center.
The Conclusion: A Network That Needs Glue
The paper concludes that the GBA is building a great foundation for traditional medicine innovation, but the "glue" holding the network together is weak.
- The Problem: Too many isolated islands. The "Sun" (Guangzhou) is doing all the heavy lifting, while the outer planets are drifting.
- The Fix: The researchers suggest building a "public service platform" (like a community center) to help the isolated dots find each other. They want to encourage the "Sun" to share its light with the outer cities and help the "MVP" universities connect with smaller companies.
In short: The GBA has the talent and the resources to be a global leader in herbal medicine patents, but right now, everyone is working in their own little bubble. The goal is to turn those bubbles into one giant, interconnected web.
