The International Power Structure System in South Asia and Its Operational Mechanisms Based on Social Network Analysis(SNA)
This paper utilizes Social Network Analysis to map the multi-dimensional power dynamics among South Asian nations and China, revealing a core-periphery structure dominated by India, characterized by tight economic interdependence but sparse military ties, and evolving toward a multipolar system through external intervention and alliance balancing.

Imagine the world of international relations not as a board game with rigid rules, but as a giant, buzzing social network, like a massive group chat where every country is a user. In this digital town square, some users are "influencers" with millions of followers, while others are quiet lurkers who only speak to a few neighbors. Scientists who study these connections use a tool called Social Network Analysis (SNA). Think of SNA as a super-powered magnifying glass that doesn't just look at what one country says or does in isolation; instead, it maps out the invisible lines of friendship, trade, and tension connecting everyone. It asks questions like: Who is the most popular kid in the room? Who holds the keys to the group chat? And if one person leaves, does the whole group fall apart? Understanding this "power map" is crucial because it helps us see why countries team up, why they fight, and how a small change in one corner of the world can ripple out to affect everyone else.
This paper takes that magnifying glass and points it specifically at South Asia, a region with seven main countries (India, Pakistan, Nepal, Bhutan, Sri Lanka, the Maldives, and Bangladesh) plus a very important neighbor, China, who acts as a key outside player. The authors built a complex, multi-layered model to see how these nations interact through four different "lenses": money (economics), weapons (military), location (geography), and ideas (how they vote together at the UN). They didn't just guess; they fed real data from 2000 to 2019 into their computer model to see what the network actually looked like.
Here is what their digital map revealed. First, the region is split into two very different worlds. In the world of money and trade, the countries are best friends. The network is incredibly tight, with a "density" score (a measure of how connected everyone is) staying above 0.98. It's like a group of friends who are always texting, sharing snacks, and doing business together. In this economic club, India is the undisputed superstar, sitting in the center of the room with the most connections. Pakistan is the second most popular, acting as a secondary hub. The other five countries form a "periphery," hanging around the edges but still deeply connected to the big two. This structure is so strong that the math shows a "fitting correlation coefficient" of 0.964 by 2019, meaning the core-periphery pattern is a solid, real feature of their economy.
However, switch the lens to military and weapons, and the vibe changes completely. Here, the countries are strangers. The network density drops to a tiny 0.2, meaning they barely trade weapons with each other. Unlike the money world, there is no clear "best friend" circle in the military world. The data suggests that weapons flow in only one direction (like a one-way street), so no tight, mutual alliances form. While India still holds the most military power, the network doesn't organize itself into a neat core-and-edge pattern like the economy does. It's more like a group where everyone has their own private security guard, but they aren't really sharing guard duties with each other.
The authors also looked at how the group behaves when you add China into the mix as a major outside player helping with development projects. Even with China's influence, the model suggests that the smaller countries (the "lower levels" of the power structure) are actually quite good at sticking together. They aren't just passive followers; they have enough direct connections to each other to keep the whole group stable. The "cohesion index" for the real-world model is 5, indicating that even though India and Pakistan are the big bosses, they haven't broken the group apart. The smaller nations still talk to each other, and the whole system remains connected and functional.
One interesting twist the paper found is a shift around 2010. Before that year, the economic network was a bit chaotic and messy (high "structural entropy"). After 2010, it became more orderly and organized, suggesting that external factors helped the region get its economic act together. But in the military world, things have stayed consistently orderly (low entropy) because the power gap between India and everyone else has always been huge and unchanging.
In short, this study suggests that South Asia is a place of contradictions: it's a tightly knit family when it comes to buying and selling, but a collection of isolated individuals when it comes to fighting. India is the clear leader in both, but the smaller countries aren't helpless; they have built their own web of connections that keeps the whole region from falling apart, even as the big powers play their games. The authors note that while their model is very detailed, it's still a snapshot of static connections, and future research might need to look at how these friendships change over time or how new things like digital information flow might reshape the map.
