Concentrated Industry vs. Dispersed Industry

In 1936, after researching the technology Basic Machine Tools, the player has a choice between two industrial technologies: Concentrated industry and Dispersed industry. These two branches are mutually exclusive, meaning that the player may only go down one of this two branches. Each of these has its positives and its negatives, and it depends on the players play style.

• Concentrated Industry - Has 5 levels that can be researched which span from 1936 to 1943 Each new level provides the same bonus as previous levels. By choosing Concentrated Industry, the player is increasing his production substantially. This will allow the player to build more factories, and make pre-existing ones more efficient

• Dispersed Industry - Like Concentrated Industry, Dispersed Industry has 5 levels that can be researched between 1936 and 1943 Each new level provides the same bouses except the first one, which provides different rewards than the rest.

Comaprsion

Should a player select Dispersed Industry, it will boost not only their output, but also their ability to protect their factories, and switch production with fewer drawbacks.

Both are very beneficial to any player as they buff your production. Though both are good, players may want to select the one complementary to their play style. Dispersed Industry is usually picked by players playing minor nations with small air forces, as it allows them to protect their factories from enemy tactical or strategic bombers without worrying as much about protecting them. It also provides a more substantial buff to many aspects of production. Meanwhile, Concentrated Industry is usually picked by more powerful nations with an already established industry, and a large military and air force, as it will raise their production through the roof. Although all the bonuses Dispersed Industry gives more of an instant production boost compared to Concentrated Industry, Concentrated Industry is stronger in the endgame, when most of the technologies are researched. In the end, it is up to the player to pick whatever suits them.
