In Workers & Resources: Soviet Republic, the player works towards building a self-sufficient republic by constructing Buildings, Utilities, Infrastructure, and other construction projects. There are two ways to complete a construction project:
Funding with currency
Construction with resources
The cheapest way to build the republic is for the player to build everything himself using construction facilities and the proper resources.
Funding with currency is importing resources and labour (and in non-realistic mode, importing magic labour that doesn't need transporting to site). It doesn't really affect your internal "market".

It has been awhile since I played, I may be confused.
