四カ年計画
The Four Year Plan favoured both the protection of agriculture and the promotion of autarky (economic independence) for Germany. Göring was put in charge of the Four Year Plan at its inception and given plenipotentiary powers. He had complete control over the economy, including the private sector, especially after the Minister of Economics, Hjalmar Schacht, had begun to lose favour with Hitler for opposing the growing military expenditures at the expense of civilian economic growth. During the following years, the state, under Göring Works (Reichswerke), began building refineries, aluminium plants, and factories for the development of synthetic materials.
