経済学の理論化― リカード「経済学原理」成立からマルクス『資本論』三部構成の完成まで―

This book is the culmination of decades of research by Tsuyoshi Sakurai on the theory of prices of production in Marxian economics. Starting with the establishment of deductive economic theory in David Ricardo's Principles of Political Economy and the dilemma of "value modification" he faced, the author meticulously traces how Karl Marx attempted to overcome this theoretical bottleneck, ultimately leading to the three-volume structure of Capital. Sakurai challenges the traditional mathematical interpretations of the "transformation problem" (the transformation of values into prices of production), rejecting the idea of a quantitative "modification" within the same dimension. Instead, he argues that Marx's true methodological intention in Volume III of Capital was to reveal the structural dynamic in which "value" (the intrinsic, invisible essence) undergoes a dimensional "transformation" or "inversion" (Gestaltung) into "prices of production" (the concrete, phenomenal form in a real competitive market). As explicitly reflected in the title, The Unfinished Theorization of Economics, the author highlights that the formulation of pure economic principles remains incomplete. Marx's profound methodological intention was left unfinished due to his passing and Friedrich Engels's subsequent editing of Volume III, which left behind methodological ambiguities. Furthermore, Sakurai points out that later Marxian economics, including the theories of Kozo Uno, have failed to fully realize and complete this structural logic. This work serves as a critical re-examination of the scientific "principles" of economics, paving the theoretical pathway to fulfill the still-unfinished theorization of capitalism.
