I think it's mostly down to human nature. People are tribal. If there's more people around one who are risk taking and trying to innovate, then others feel also more inclined to go down this path, whereas if there's almost nobody around one to do their own startup, then other people will also be less likely to do it, because noone wants to be alone in their risk taking. It's seen everywhere in life and starts with kids. When you have one kid alone, he/she is less likely to jump of a 10m cliff, but if you have a group of kids who all jump into the water then others will follow. It's the same with adults, except you replace cliff jumping with risk taking/innovation/startups. I base that opinion, because I've seen a lot of friends/family who come from a very risk averse culture/country move to a different place and then instantly change their attitudes as they see that it's more normal elsewhere and therefore they acustom to the thinking that it's more normal and ok to do it.
