초록

본 논문은 한국, 미국, 영국의 제조업 및 전기 가스 수도사업에서 ICT 확산이 노동 및 에너지 수요에 어떠한 영향을 미치는지 연구하였다. 제조업에 대해서는 ICT 자본, 비ICT 자본, 노동, 전기, 연료, 재료를 생산요소로 가정하고, 전기 가스 수도사업에 대해서는 ICT 자본, 비 ICT 자본, 노동, 에너지 재료를 생산요소로 가정하여 요소 간 대체관계를 분석하였다. 모리시마 대체탄력성 추정결과 및 요소의 상대적 가격변화를 고려할 때, 3개 국가의 제조업 및 전기 가스 수도사업에서 ICT 자본은 노동을 대체하여 노동 수요를 감소시키는 것으로 나타났다. ICT 자본에 비해 전기 및 연료의 가격증가율이 높은 미국과 영국의 제조업에서 ICT 자본은 전기 및 연료를 대체하여 에너지 수요를 감소시키는 것으로 나타났다. 한국의 제조업에서 ICT 자본과 전기 및 연료가 대체관계에 있으나, 요소의 상대적 가격변화를 고려하면 ICT 자본이 에너지 수요 감소에 기여했다고 보기 어렵다. 3개 국가의 전기 가스 수도사업에서 ICT 자본은 에너지 재료를 거의 탄력적으로 대체하여 에너지 재료 수요를 감소시키는 것으로 분석되었다.

We investigate the effect of ICT capital on the demands for labor and energy in manufacturing and electricity gas water industries of Korea, US, and UK. Assuming ICT capital, non-ICT capital, labor, electricity, fuel, and material as input factors for manufacturing and ICT capital, non-ICT capital, labor and energy material as input factors for electricity gas water industry, we estimate the Morishima elasticities of substitution. Considering the relative price changes of input factors, ICT capital has substituted labor in manufacturing and electricity water gas industries of the three countries. ICT capital has substituted both electricity and fuel in US and UK manufacturing. Although ICT capital has substituted electricity and fuel each other in Korean manufacturing, ICT capital is unlikely to decrease the demands for electricity and fuel when considering their relative price changes. ICT capital has substituted energy material in electricity gas water industries of the three countries.
