Ersatz is a German word literally meaning substitute or replacement. Although ersatz is used only as an adjective in English, Ersatz can function in German either as a noun on its own, or as an adjective in compound nouns such as Ersatzteile (spare parts) or Ersatzspieler (substitute player). While the English term often implies that the substitution is of unsatisfactory or inferior quality, this connotation does not necessarily exist in the German context.
Another example of the usage of the word Ersatz in Germany is the German naval construction programs of the beginning of the 20th century, which would use the phrasing "Ersatz (shipname)" to indicate that a new ship was a replacement for an aging or lost previous ship, generally by a new, larger or more capable vessel. Because German practice was not to reveal the name of a new ship until its launch, this meant that the vessel was known by its "Ersatz (shipname)" throughout its construction. At the end of World War I a class of incomplete battlecruisers was known simply as the Ersatz Yorck class, since the first ship was considered to be a replacement for the lost armored cruiser SMS Yorck.
Relating to the scholarly work of Kunio Yoshihara, ersatz capitalism refers to the early rising economies of East Asian and their dynamic and techonology intensive developments. Yoshihara's definition classifies Japanese, South Korean and Taiwanese nations' capitalist drives as what might be called "false capitalism." This refers to such government and business actors' abilities to utilize a nation's comparative advantages and artificially motivate an economy towards higher end economic activities, specifically similar to those of developed Western nations, including areas such as capital investments and technology intensive production.
