본 연구는 경쟁도입이 비 체화된 기술진보에 반영된다는 가정에서 Habijn(2000)의 비 체화된 기술진보추출 방법론을 이용하여 1975년부터 2002년까지 정보통신서비스산업의 비 체화된 기술진보를 식별하였다. 또한 Bai et at.(1998, 2003)이 제시한 구조변화추정방법론을 이용하여, 상기 비 체화된 기술진보 측정치에 대한 구조변화시점을 추정하였다. 추정된 시점에 대한 실증분석결과를 보면, 비 체화된 기술진보의 구조적 변화시점은 본 연구대상자료의 21번째 자료년도인 1995년으로 나타났다. 또 다른 비 체화된 기술진보의 구조변화는 15번째 자료순서인 1989년도에 나타났다. 역시 다른 물리적 감가상각를$(5\%)$을 이용한 비 체화된 기술진보에 대하여 구조변화분석을 실시할 경우, 1995년도와 1981년으로 나타났다. 따라서 1995년 전후에 비 체화된 기술진보의 구조적 변화가 발생했다는 사실을 알 수 있었다. 이러한 실증분석결과는 다른 계량적 검증을 통하여 뒷받침되었다. 따라서 본 연구의 실증분석결과로 볼 때, 1995년 이후에 정보통신서비스산업에서 비 체화된 기술진보성장의 발전경로상에 커다란 구조변화를 경험하였으며, 새로운 경쟁도입이나 해당 산업활성화정책은 정보통신서비스산업발전에 긍정적 역할을 수행했음을 알 수 있었다.

This paper empirically investigates the rates of embodied technological change and their relative contributions to total factor productivity growth for manufacturing, using the Korean plant-level manufacturing data for the period of 1985-2003. We adopt a production-based estimation method proposed by Sakellaris and Wilson (2004) in order to examine the marginal productivity increase of each vintage of equipment over time. We find that the rate of embodied technological progress of Korea's manufacturing sector maintains the annual average level of 13.7 percent from 1985 to 2003, slightly lower than 16.9 percent of the U.S., estimated by Sakellaris & Wilson (2004). While the rate recorded a remarkable increase after the 1997 financial crisis, IT-producing and IT-using industries achieved higher rates of embodied technological progress than non-IT counterparts.

The paper tests the embodiment hypothesis by measuring the technological obsolescence of a specific year (1990)'s technology and investigating the relationship between labor productivity and technological obsolescence. This approach is based on Salter (1969) that emphasizes the economic aspect of technology. We use the rate of economic surplus as the proxy of technological obsolescence for 10 main industries, including food processing, textiles, chemicals, non-steel metals, steels, metal products, machinery, electronics, precision machinery, and transportation equipments. The result shows that the embodiment hypothesis is not accepted for the overall manufacturing sector. However, we found the vintage effect - a positive relationship between technological obsolescence and labor productivity over time - in textiles, chemicals, non-steel metals, metal products, electronics, and transportation equipments. Therefore, the government should support R&D investment as well as capital equipments investment for the industries with large vintage effect.

This paper aims at examining the disembodied technological progress in the Korean IT service industry, on the assumption that competition leads to the disembodied technological progress. Hobijn model (2000) which abstracts the disembodied technological progress from the total technological progress and Bai et al. Model (1998, 2003) which identifies time of the technological structural change are used for empirical study. The empirical analysis indicates the major structural change in the pattern of the disembodied technology progress occurred after 1995 in the Korean IT service industry. This means that policies for the introduction of competition system and the industry promotion around 1995 have a positive effect on the development of the Korean IT service industry.

콘텐츠 산업은 디지털 기술의 발달로 콘텐츠 속성이 아날로그에서 디지털 융복화로 변화되고 있으며, IPTV, DMB, WiBro, 3DTV 등과 같은 뉴미디어를 통해 융복합 서비스로 제공되고 있다. 또한 디지털콘텐츠 산업의 영역은 과거 엔터테인먼트 위주에서 미래에는 제조, 서비스를 포함한 산업 전영역에 체화 및 융합되어 산업의 경계를 초월할 것으로 전망된다. 이러한 콘텐츠 산업에 있어서의 융합 현상은 산업간 경계약화, 기술의 발달 및 고객수요의 다양화 등에 의해 빠르게 확산중에 있으며, 특히 문화기술(CT)의 진보가 근본적으로 콘텐츠 산업에서의 융합을 가속화시키고 있다. 이에 본 연구는 콘텐츠 산업에서의 융합 유형을 4가지(강화, 확장, 결합, 창조)로 구분하여 주요 사례들을 살펴보고, 미래 콘텐츠 산업의 트렌드를 전망해 봄으로써 융합형 콘텐츠 산업의 육성 및 발전을 위한 정책을 수립하고 시행하는 데 기여하고자 한다.

This paper provides a new method of measuring the degree of technological progress which contributes to real economic growth based on Schumpeter's Trilogy. Using Microdata of Statistics Korea, the results of measuring and comparing the actual growth contribution of technological progress during the period 2003-2018 by the total factor productivity growth rate(growth accounting method), the R&D investment contribution rate, and the Schumpeterian innovation growth rate, respectively are as follows. First, the measurement of the real growth contribution of technological progress by the growth rate of total factor productivity and the growth rate of Schumpeterian innovation shows contradictory results. Second, when the growth rate of production is in a decreasing trend, the difference between the growth rate of production and the growth rate of total factor productivity increases compared to when it is in an increasing trend. Conversely, when there is an increasing trend, the difference between the growth rate of production and the growth rate of total factor productivity becomes smaller compared to when it is in a decreasing trend.. Third, the technological opportunity that affects the innovation growth rate, i.e., the contribution of R&D incentives to innovative growth is only 3.3%. The reason why this result is different from the existing perception of the contribution of technological progress to growth is that different entities are being measured while measuring the same term of technological progress. Therefore, the growth rate of total factor productivity should be used to measure macroeconomic efficiency, R&D investment should be used to measure the effectiveness of new technology supply, and the Schumpeterian innovation rate should be used to measure the economic impact of technological progress. The policy implications of the research results of this thesis are as follows: ① Transition from a policy of one-sided technology supply to a policy of convergence of technology supply and new technology demand support, ② Mission-oriented R&D policy and R&D policy that links national R&D with private R&D, ③ Reclassification of capital goods reflecting the degree of new knowledge.

This study re-evaluated Malthusian regime which signifies a negative relationship between population and income by employing the trend for the population and the income of the world and panel analysis during 1820-2006 periods. Empirical evidence suggested that Malthusian regime was existed during 1900-1994 periods in the world economy. Even each country had experienced such regime in its own economic growth path. However, the population drastically decreased and output upsurged since 1995, Malthusian regime had not been revealed any more since then. Such phenomenon is mainly resulted from the output is rather increased geometrically when the population is decreased because of a social reason such as decreasing in fertility rate. In addition to this, the population contributes to the production not by a quantity but a quality which is embodied by capital. Particularly, when the population which is associated with demand side is counted, the population is said to be evolved continuously in economy.
