지역별 광공업 총요소생산성 분해 = Decomposition of total factor productivity in mining and manufacturing industry of regions

국문 초록 (Abstract)

본 연구는 1999년부터 2007년까지의 패널데이터를 이용하여 194개 지역별 광공업의 총요소생산성의 변화를 추정하고, 이를 기술진보, 기술적 효율변화, 규모효율변화, 배분효율변화로 분해하였다. 또한 시차를 고려한 트랜스로그 확률변경생산함수를 사용하여 이에 대한 검정을 실시하였다. 따라서 본 연구는 시차를 고려하여 지역별 총요소생산성의 변화를 추정하고 그 요인을 분해하는 것을 목적으로 한다.
분석결과 지역별 총요소생산성의 증가에는 기술적 효율변화가 존재하는 것으로 분석되어 기존의 연구와 구별되었으며, 기술진보 및 규모효율변화, 배분효율변화에 의해 구성되는 것으로 나타났다. 기술진보는 수도권 일부, 대도시, 전남권, 및 경남권, 기술적 효율변화는 수도권 일부, 강원권, 충북권, 경북권에서 증가한 것으로 분석되었다. 규모효율변화와 배분효율변화는 수도권 및 대도시에서 규모의 경제를 형성하고 효과적인 자원배분이 이루어진 것으로 나타났다. 따라서 본 연구는 지역별 총요소생산성의 변화를 기술진보, 기술적 효율변화, 배분효율변화, 그리고 규모효율변화로 분해함으로써 지역별 광공업의 총요소생산성을 이해하는데 부가적인 정보를 제공하였다.

We present in this paper the change of total factor productivity(TFP) and its contributing factors. This study uses translog stochastic frontier production function to decompose TFP into technical progress, technical efficiency change, scale efficiency change, and allocation efficiency change along with consideration of mining and manufacturing industries in 194 municipal regions in Korea. Also, this study takes considerations of several hypotheses including choosing translog functional form in stochastic frontier function.
According to the results of this study, there exist firm components which compose the growth of total factor productivity. Regional growth of total factor productivity is primary affected by technical progress and technical efficiency change, and secondary by scale efficiency change and allocation efficiency change. Technical progress is showing higher change in Jeon-nam, Gyeong-nam province, and metropolitan area. Technical efficiency change is shown up in Gang-won, Chung-buk, Gyeong-buk province, and also in metropolitan area. Metropolitan area including metropolis have prominent scale efficiency change and higher allocation efficiency change, which implies these cities are already reached a certain size where scale economies no longer existed. Also, these cities have less allocative inefficiency. This study provides additional insight of TFP growth in Korean manufacturing by decomposing TFP growth into technical progress, technical efficiency change, scale efficiency change, and allocation efficiency change
