한국경제에서의 이윤율의 추계 및 결정 요인 분석 = The Estimating of and the Analysis of Determinants of the Profit Ratio in the Korean Economy

다국어 초록 (Multilingual Abstract)

The method in which we estimate the rate of profit is separated into the estimation of price unit and that of value unit. The value unit here setforth means that the statistical data of price unit is transformed into that of the labour time unit.
We estimate the rate of profit by the statistical data of value unit in this thesis, because value unit can reflect the productivity of labour more correctly than price unit. The estimating method by value unit is also divided into the method of 'input-output table' and that of 'the monetary express of the value'. We estimate the profit rate of total industry and manufacture department in the Korean Economy from 1970 to 1988 by value computation based on these two estimating method.
Through the results of these estimates, we can see that these rates of profit shows similier trends to each other. We can survey that the rate of profit fluctuates approximately at the peak of the years 1972,3 and the trough of 1975, the peak of 1978 and the trough of 1980, and the peak of 1986. Although the rate of profit of manufacture is higher than that of total industry, it seems that this cyclical aspect is represented nearly the same in the manufacture too. Through the results of these two estimates, the average fluctuation volume of the rate of profit for the entire period fell within narrow limits, but it rose slightly for the 1980s alone. It means that we will convince of the law of the rate of profit to fall for the estimating periods.
Such a result could be got through the rise of labour productivity. First, the improvement of labour productivity generated the rise of surplus-value rate through the increase of relative surplus-value. Secondly, the improvement of labour productivity deterred the rise of the value composition of capital because it exceeded the technical composition of capital. Therefore the rate of profit has been cyclically fluctuated by the rise and/or fall of the rate of surplus-value and the value composition of capital.
