디지털네트워크 경제의 가격형성과 축적동학

Abstract

It is argued that the micro price formation and macro aspect of capital accumulation in digital network economy could be explained by the Marx's value theory and dynamic accumulation theory. The reason is provided why the price of information goods must comprise the three ingredients, that is, production price(PoP), temporary extra(or temporary) surplus value(TSV), monopoly profit(Pm). The specific reason due to which TSV and Pm get large at first and undergo an unstable path is laid down. From this, the specific dynamics of accumulation of IT industry largely is derived. When capital accumulation proceed from the competitive phase to the monopolistic, Pm and thus profit rate suddenly swell up. The result is the huge increase in investment, productivity. But the new technology and innovation accelerate competition within this industry and thereby TSV and Pm become unstable and unsustainable. When the phase of monopolistic form of competition gives way sooner or later to the competitive phase, the profit rate decreases rapidly. These phases constitutes the specific pattern of accumulation dynamics of IT industry and to a lesser extent digital economy as a whole.
