한국의 총요소생산성 추정과 생산성 결정요인에 관한 실증연구
주연화 국제지역학회 2018 국제지역연구 Vol.22 No.4
본 논문은 분석기간 1975:1-2016:4에 걸쳐 한국의 제조업과 서비스업을 대상으로 확률변경함수로서 초월대수(Translog) 생산함수를 이용하여 총요소생산성을 추정하였다. 또한 추정된총요소생산성에 영향을 미치는 결정요소로서 산업의 구조와 특성을 반영하는 마크업, 자본탄력도 그리고 수입중간재비중을 포함하는 자기회귀시차모형을 설정하여 총요소생산성의 결정요소탄력도를 추정하였다. 총요소생산성 증가율은 분석기간 평균값이 제조업은 0.0199 그리고 서비스업은 0.0063으로 추정되었다. 총요소생산성의 마크업탄력도는 제조업은 2.481로양(+)의 값을 나타낸 반면 서비스업은 -1.403으로 음(-)의 수치를 보이고 있다. 자본집약도탄력도는 제조업은 0.651 그리고 서비스업은 0.042로 추정되었다. 이러한 실증결과는 산업구조와 특성을 반영하는 마크업과 자본집약도가 제조업과 서비스업의 총요소생산성에 영향을미치는 중요한 결정변수임을 밝히고 있다. This paper is to estimate the total factor productivity(TFP) in the Korean manufacturing and service industries during the period 1975:1-2016:4 using the stochastic frontier analysis model. In order to analyze the determinants for the total factor productivity the paper estimates the industry-specific determinant elasticities of TFP using the autoregressive distributed model. The industry-specific determinants, which reflect the industrial structure and properties include markup, the ratio of capital to labor(KL), and the ratio of foreign intermediate goods (FIG) to industrial output. The average value for total factor productivity growth was estimated to be 0.0199 in manufacturing and 0.0063 in the service industry. The markup and KL elasticities of TFP were estimated to be 2.481 and 0.651 in manufacturing respectively and -1.403 and 0.042 in the service industry respectively. The empirical results suggest that the industrial markup and the ratio of capital to labor have had decisive effects on the changes in the total factor productivity in the Korean manufacturing and service industries during the period 1975:1-2016:4.

주연화 한국근현대미술사학회(구 한국근대미술사학회) 2024 한국근현대미술사학 Vol.48 No.-
본 논문은 2000년 이후 한국미술시장의 글로벌화를 한국 갤러리, 옥션의 해외 진출과 해외 갤러리, 옥션, 아트페어의 국내 진출로 나누어 그 시대적 배경과 진출 양상 및 전략, 그리고 각각의 한계를 분석하고, 여전히 남아있는 한국미술시장 글로벌화의 숨은 과제를 제시하는 것에 목적을 둔다. 2000년대 이후 한국미술시장은 한국 갤러리가 적극적으로 글로벌 미술시장에 진출하는 시기와 해외 글로벌 갤러리와 아트페어가 국내에 유입되는 시기로 구분해 볼 수 있다. 본 논문에서는 그 구분 시점을 페로탱(Perrotin) 갤러리가 서울 분점을 오픈하는 2016년으로 삼는다. This paper aims to analyze the globalization of the Korean art market since the 2000s, focusing on the overseas expansion of Korean galleries, as well as the entry of international galleries and art fairs into the domestic market. It examines the historical context, strategies, and limitations of these expansions, while also highlighting the ongoing challenges in the globalization of the Korean art market. Since the 2000s, the Korean art market can be divided into two periods: one when Korean galleries actively entered the global art market, and another when international galleries and art fairs began to emerge domestically. This paper designates the opening of the Perrotin gallery’s Seoul branch in 2016 as the turning point.

A Comparative Analysis of Solow Residuals in Korean and China Manufacturing Industries
주연화,박세훈,정석중 국제지역학회 2014 국제지역연구 Vol.18 No.1
The Korean economy has accomplished the high rates of economic growth during the last four decades through the export-led growth strategy by the government. It is well recognized that the export in the Korean manufacturing industries has been still leading the Korean economic growth. On the other hand the Chinese economy has also achieved rapidly economic growth since 1990's. The cyclicality of productivity has been one of the essential issues in economics. Since Solow(1957) developed the dominant approach to the measurement of productivity growth, Solow’s approach, which assumes the perfect competition, the constant returns to scale, and the full use of input factor has been modified particularly in Hall’s(1990) and Basu’s(1996) works. This paper establishes the empirical model based on Hall’s and Basu’s models, estimates 4 types of Solow’s residuals in 8 Korean manufacturing industries and in Chinese economy and analyzes the cyclicality of measured productivity, comparing the productivities in both countries.

주연화,강주훈,박세훈 국제지역학회 2015 국제지역연구 Vol.19 No.2
The Korean economy has achieved the high rates of economic growth during the last four decades through the export-led growth strategy by the government. It is well recognized that the export in the Korean manufacturing industries has been still leading the Korean economic growth. The purpose of this paper is to investigate the importance of industry-specific variables in determining the export performance of manufacturing industries in Korea during the period 1975:1-2010:4 using data pooling analysis. Our main findings are summarized as follows. The effect of markup on export growth is highly significant with positive sign. The rapid declines in interest rates and import prices since the foreign crisis occurred should have resulted in the cost advantages in exporting industries, which in turn could have substantially contributed to export growth. Thus, it may be concluded that the ratio of capital to labor and the ratio of foreign intermediate goods to industrial output are significantly industry-specific determinants in explaining the export performance.

Empirical Analysis on the Industrial Productivity in the Electricity·Gas·Water Service Sector
주연화,강주훈,박세훈 한국산업정보학회 2015 한국산업정보학회논문지 Vol.20 No.4
The early studies indicated that the firm with monopoly power is likely to engage in X-inefficiency such as a managerial slack. The reflection of the X-inefficiency theory has led to the issue that the public sector may be more inefficient than the private sector. In Korea like other many countries the electricity·gas·water service which can be considered as natural monopoly have been provided mostly by the public sector. In order to provide the empirical evidence to the argument that the public sector may be more inefficient than the private sector this paper estimated the four types of Solow residual which is called the total factor productivity in the electricity·gas·water service industry with the associated empirical model and compared its productivity with one in the manufacturing industry. The empirical results do not support the argument that the public sector may be more inefficient or less productive than the private sector.
