How important is national identity to a country's economy, for example buying locally produced goods?

I'd say national identity plays a significant role in economic decisions, especially when it comes to consumer behavior. The main reason is that people often associate local products with cultural pride and quality assurance. For example, in Hangzhou where I'm from, Longjing tea has this strong reputation not just because it's good, but because it's deeply tied to our local heritage. Many residents prefer buying it over imported teas, even at higher prices, because it feels like supporting our own traditions. That said, I think the balance is important - while local pride matters, being too protectionist could limit choices and innovation in the long run.
