Concentrated vs. dispersed industry

In 1936, after researching the technology  basic machine tools, the player has a choice between two mutually exclusive industrial technologies branches: Concentrated industry and dispersed industry. Each of these has its positives and its negatives, and it depends on the player's 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

Has also 5 levels that can be researched between 1936 and 1943. Each new level provides the same bonuses except the first one, which provides different rewards than the rest. By choosing dispersed industry, the player is reducing vulnerability to bombing and allows for quicker changing of production lines.

Concentrated industry vs. dispersed industry

Modifier	Concentrated industry	Dispersed industry
Factory output	+75%	+50%
Dockyard output	+50%	+50%
Max factories in a state	+100%	+100%
Production efficiency retention	–	+50%
Production efficiency base	–	+25%
Factory bomb vulnerability	–	−55%

One can think of the two styles as maximizing potential production at any given production efficiency vs. decreasing time to achieve 100% production efficiency.
