The Economic History Association's website has an article on the economic history of Finland, though that's more about the how (e.g. which industries were growing, trade patterns, etc) than the why. 

Finland also shares some elements common to other developed countries: relatively low corruption, and high levels of social trust - note my references are to recent data but these sorts of things are generally very persistent over time (occasionally some political genius pulls off a large improvement.) The linkages between these and economic outcomes is fairly logical, they tend to drive a competent(ish) governing system that can protect important civil and economic liberties and change laws when they turn out to be a bad idea. And, as a small economy where trade was very important, the Finnish government had strong incentives to pay attention to feedback from international markets (like the other Nordic states). 

But what drives the low corruption and social trust in the first place? Unfortunately there is very little academic research on this,  as it's hard to get objective data, particularly before people started doing systematic surveys on these questions post-WWII. However, an interesting article published in Science in November 2019 attributes the unusual psychological properties of Europeans, including higher rates of social trust, to the Western Church. The argument is that the Western branch of Christianity, that evolved into the Roman Catholic Church, transformed European kinship structures by means like banning cousin marriages. This is clearly not the full story, it doesn't explain why the Nordics have such higher rates of social trust than countries in Europe that were Christian longer (e.g. Italy), it doesn't account for a number of non-western countries like Japan and Saudi Arabia which show strong levels of social trust, and it is very new research so it may be that someone will discover a mathematical error in it. But it is an interesting idea as at least a partial explanation of why so many European countries saw strong economic development, under such a variety of different conditions.

In summary, Finland shares a number of cultural properties in common with other developed countries.
