한국경제 비생산적 부문의 추이에 관한 시계열 분석 = Time-series Analysis of Unproductive Sectors in Korean Economy

다국어 초록 (Multilingual Abstract)

We are going to view what has been the role of unproductive sectors in the process of economic development in Korea through this study. There are still various debates in making distinction between productive and unproductive labours and between productive and unproductive sectors We regard as productive labor and sector the one which produce use value and surplus value. At frist, we divided various industries of Input-Output table, changed system of the table in accordance with the theory of productive labour, and then viewed the trend of unproductive sector in time-series. Particularly we made a research upon the role of the unproductive sectors throughout the 70s and 80s with its change in final demand, total output, and employment, and we also upon the feature in relation with the aspect of labour absorption.
We have come to several conclusions :
first, we have confirmed that the share of unproductive sector, in terms of the demand and input in Input-Output table and of employment aspect, has consistently increased.
Second, since unproductive sector is unable to produce use value or surplus, there could be a hypothesis of which the increasing share of unproductive sector is against capital accumulation of productive sector. And the result of statistics has provided a vene of possiblity to take the hypothesis.
Third, in the matter of how much absorption of productive labour and unproductive labour have accomplished in producing net value of labour, the share of unproductive labour increased a lot in the late 70s. However, there has been decline of the share since the early 80s due to the absorption of productive labour in oversea in dustries and formation of fixed capital.
Therfore, the Korea economy should restrain the increase of input towards unproductive sector in order to defend the potential of economic growth from impediment of capital accumulation.
