This book, first published in 1936, analyses the then-recent phenomenon of industrial combination. Concentration was new. Industrial combination was new. The interlocking of finances was new. The role of banks in regard to industry was new. The domination of financial capital over large sectors of industry was new. The author examines the new industrial system as it was, on the cusp of new world-economic conditions, resulting from and manifesting themselves in a revolution in transport, the creation of concentrated mass supply and mass demand, changes in the distribution of raw material supplies and the adaption of the technical and economic structure of the industrial unit to these new conditions.
