Sichuan Province in China has witnessed a remarkable surge in tourism over the past eight years. This growth isn't just about more tourists visiting; it's about how they navigate through the province. Picture Sichuan as a vast web, with cities and tourist attractions as the nodes. The lines linking these nodes represent tourism activities and economic exchanges.

The web is expanding rapidly. Key areas like Chengdu are becoming increasingly significant. These places act as the main hubs of the web, spreading tourism activities to other parts of the province. This phenomenon is often referred to as the "spillover effect. " It's similar to dropping a pebble in water and watching the ripples spread out. In this case, the ripples are tourism activities moving from one area to another.

However, despite this growth, the web is still quite loose. It's like a net with large holes. This means there's still room for more connections. Over time, these connections are getting tighter, forming a pattern that resembles a main road with many smaller paths branching off. This pattern is known as a "one axis with multiple branches" structure.

Not all cities are equally important in this web. Some cities have more connections than others. They play a bigger role in the tourism economy. This concept is known as "centrality. " It's like how some people are more popular and have more friends in a social network.

Several factors are driving this growth. First, the closer two places are, the more likely they are to be connected. This makes sense, right? But it's not just about distance. The amount of tourism resources, like scenic spots and cultural sites, also matters. The more resources a place has, the more likely it is to attract tourists and form connections with other places.

Economic development and tourism reception capacity also play a role. If a place is doing well economically and has the infrastructure to handle tourists, it's more likely to be a hub in the tourism web. But here's a surprise: the shortest road distance between two places can actually make them less connected. This might be because shorter distances mean less need for travel, which means fewer tourism activities.
