Based on Germany’s globalism and regionalism discussed in Chapter 13 , this chapter considers German capitalism and corporate expansion concerning special historical conditions in each period, which differed from the postwar period, regional conditions in Europe, and relationships between German and American capital. From the comparative perspective with the period after World War II, the reason why German capitalism and enterprises were forced to face limitations in their development and the full-scale deployment of American management methods (“Americanization”) was impossible until the end of World War II but became possible after the war is examined. First, this chapter considers the development of German capitalism and corporate expansion concerning historical conditions before the end of World War II and regional circumstances in Europe. Next, it compares market structures before and after World War II and among the three major countries: Germany, the United Kingdom, and France. Furthermore, the relationships between the German and American capital during the interwar period are discussed. Following these examinations, issues regarding Fordism as a capitalistic accumulation system are analyzed and compared with the period after World War II.
