Changes in Variety, Price, and Quality of Chinese Export Products in Trade with Korea

Taegi Kim 한국경제연구학회 2013 Korea and the World Economy Vol.14 No.2

This paper analyses the changes in the variety, price, and quality of Chinese export products, and their contributions to China’s export growth into the Korean market, using HS 10-digit highly disaggregated Korean trade data between the years of 1992 and 2008. In this paper, empirical methodologies for estimating the price level and quality level of Chinese products are developed. Our results show that China’s export growth is mainly explained by an increase in the intensive margin, and that the rise in the intensive margin is due to a decrease in price and an increase in quality of Chinese products. Even if an increase in product variety and a decrease in price have contributed to China’s export growth, the improvement in product quality is the main factor affecting China’s rapid export growth into the Korean market.

Korea's Bilateral Trade with Japan and the United States: A Comparative Study

Taegi Kim,Hong Kee Kim 서울대학교 경제연구소 1999 Seoul journal of economics Vol.12 No.3

This paper examines the development of Korea's trade structure with Japan and the United States over the past 30 years. Three aspects of the trade structure are investigated: changes in trade patterns, changes in the decomposition of total trade growth, and import and export elasticities. We find that there are major differences between Korea's trade with Japan and Korea's trade with the United States: Korea's intra-industry trade with Japan is higher than that with the United States. The contribution of intra-industry trade to Korea's total trade growth has increased over time. The trade pattern of Korea with Japan has become more similar to that with the U.S. in terms of intra-industry trade while it has diverged from it in terms of inter-industry trade. Also, Korea's import and export price elasticities are larger for trade with the United States than for trade with Japan.

Resistance Switching Characteristics of Transparent HfO₂-based RRAM: Impact of Rough Surface Bottom Electrode

Taegi Kim(김태기),Hee-Dong Kim(김희동) 대한전자공학회 2024 대한전자공학회 학술대회 Vol.2024 No.6

Here, we present a method to enhance the performance and reliability of transparent memristor devices by optimizing the roughness of the indium tin oxide (ITO) bottom electrode (BE) without extra process. By adjusting the sub-heater temperature during ITO deposition, we achieve a rough surface BE, leading to improved resistive switching (RS) characteristics compared to flat surface BE The devices with rough surface BE exhibited lower forming voltages and stable RS behavior with high endurance and on/off ratios. This enhancement is attributed to better regulation of electric field distribution and concentration of oxygen vacancies, making rough surface devices promising for low-power and reliable transparent memristor.

Industrial Structure, Regional Trade Bias, and China's FTA with Korea and Japan

Taegi Kim,Jun-Heng Zhan 서울대학교 경제연구소 2006 Seoul journal of economics Vol.19 No.4

This paper investigates the potential for China's FTA with Korea and Japan. We examine the similarities of industrial structures and regional trade biases among the three countries as indictors for establishing a China-Korea-Japan FTA. Even though the three countries are at very different developmental stages, their industrial structures will converge over time and their regional trade bias is high. Regression results of the gravity equation show that the trade volume among the three countries will increase. Based on our analysis of industrial similarities, we suggest a step-by-step procedure for the economic integration of Northeast Asia. A successful China-Korea-Japan FTA can be realized through the initial establishment of Korea-Japan and China-Korea FTAs, followed by subsequent negotiations between these two FTAs.

EFFECTS OF PATENTS ON PRODUCTIVITY GROWTH IN KOREAN MANUFACTURING: A PANEL DATA ANALYSIS*

Kim, Taegi,Maskus, Keith E.,Oh, Keun‐,Yeob Blackwell Publishing Asia 2009 Pacific economic review Vol.14 No.2

<P><B>Abstract. </B> We analyse the contributions of patents to total factor productivity (TFP) performance in Korean manufacturing industries during the period 1981–1999. This paper treats potential autocorrelation problems seriously and uses recent panel cointegration approaches to investigate the robustness of the patent‐TFP relationship. The results show that both domestic and foreign‐resident patent applications have significant positive effects on productivity and that foreign‐resident patent applications have a larger effect than domestic patents in improving TFP in Korean manufacturing. We also find evidence of knowledge spillovers among industries, in that the patent applications of other industries increase TFP in any single industry.</P>

수출과 기업 성과의 관계에 대한 연구

김태기(Taegi Kim),최지혜(Jihye Choi) 한국산업경제학회 2017 산업경제연구 Vol.30 No.5

이 논문은 한국 제조업 기업의 자료를 이용하여 수출기업의 특성과 수출이 기업 성과에 미치는 영향을 분석하고 있다. 분석기간은 1984-2015년의 32년간이며, 기업 수는 제조업에 속한 1,063개 기업이다. 분석결과는 수출 기업들은 비수출기업에 비해 기업규모가 크고, 실질임금과 노동생산성이 더 높으며, 자본집약적임을 보여준다. 프로빗 분석결과는 한국의 경우도 다른 해외 연구와 마찬가지로 수출경험이 있는 기업에서 수출가능성이 더 높고, 생산성이 높은 기업이나 규모가 큰 기업, 그리고 인적자본 수준이 높은 기업에서 수출가능성이 높아짐을 보여준다. 수출이 기업 성과에 대한 회귀분석 결과에 따르면, 고용규모, 부가가치, 실질임금, 노동생산성, 영업이익 모두 수출기업에서 비수출기업보다 더 크다. 다만, 총요소생산성지수나 총요소생산성 증가율은 수출기업에서 더 높지는 않다. 그런데 수출기업중에서 수출비중이 큰 기업에서는 생산성 증가율이 높을 수 있는 것으로 나타난다. 이처럼 수출과 총요소생산성과의 관계는 복합적이다. 전체적으로 우수한 기업이 수출시장에 진입하게 되지만, 이들 기업이 수출 활동을 하면서 생산성이 높아지는가에 대해서는 명확하지가 않다. This paper analyzes the characteristics of exporting firms and the effect of exporting on firm performance using data from Korean manufacturing. The period is 32 years from 1984 to 2015, and the number of firms is 1,063 companies. The results show that exporting firms are bigger, have higher real wages and labor productivity, and are more capital intensive than non-exporting firms. The Probit analysis shows that the export possibility is higher in companies, which have previous export experience and higher productivity, and are larger in scale and in human capital. Analysis on export performance shows that employment, value added, real wages, labor productivity, and operating profit are all higher in exporting firms than non-exporting firms. However, the TFP index and TFP growth rates are not higher in exporting firms, but the productivity growth rate can be high in exporting firms with a large share of exports. This shows that the relationship between exports and productivity is complex. Overall, this study shows that firms with higher productivity enter the export market, but it is unclear whether the productivity of these firms increases as a result of export activities.

한국 제조업 기업에서 토지보유가 투자에 미친 영향

김태기(Taegi Kim),오근엽(Keunyeob Oh) 한국경제연구학회 2013 한국경제연구 Vol.31 No.2

본 연구는 한국에서 기업의 토지보유가 투자에 미치는 영향을 분석하고 있다. 연구의 대상 기간은 1980년부터 2008년까지이고, 대상 기업은 제조업의 132개 기업이다. Modigliani-Miller 정리에서는 투자의 크기는 자금조달 방법과는 무관하다고 주장하고 있지만, 미국이나 유럽 등과 달리 자금 대출에서 담보제공 요구가 일반적인 일본이나 한국에서는 기업의 토지보유가 담보가치 기능을 하여 투자에 영향을 미쳤을 것으로 생각된다. 회귀 분석 결과는 한국의 경우도 일본과 마찬가지로 토지보유나 현금보유가 투자에 영향을 미침을 보여준다. 하지만 외환위기 이후에는 이러한 영향이 약간 감소하였다. This paper investigates whether the size of investment in Koreans firms is related with the land value of the firms. For the period of 1980 to 2008, we analysed 132 Korean firms’ data. According to Modigliani-Miller, the investment has nothing to do with the financing methods under the assumption of perfect information. But we expect the investment of the Korean firms depends on the land value since there could asymmetry of information in Korean firms case and the commercial banks tend to ask the firms to provide the land as the collaterals, as in Japanese firms cases. The results of rigorous regressions in this paper shows that Korean firms’ investment relies on the land value and cash flows in the firms. But this effects seems to have been smaller after east Asian currency crisis.

한국 수출상품의 가격과 품질변화 분석

김태기(Taegi Kim) 한국경제연구학회 2010 한국경제연구 Vol.28 No.2

이 논문은 1992~2008년 기간 동안 HS 10단위의 세분화된 무역통계를 이용해 한국 수출품의 가격과 품질변화를 분석하고 있다. 분석방법으로 수입재에 비해 수출재의 가격이 더 비싼 제품의 수를 계산하고, 또 수출단가와 수출액을 이용해 품질지수를 추정하였다. 분석결과에 의하면, 한국 수출품에서 우위품질 품목수가 점차 증가하고, 또 품질지수도 점차 상승하였다. 이는 한국 수출품의 품질이 개선되어 왔음을 보여 준다 특히, 기계 및 운송산업(SITC 7)에서 품질의 증가율이 가장 높게 나타났고, 전반적으로 저기술산업보다는 고기술산업에서 품질개선이 이루어졌다. 또 상대적으로 수출액이 많은 산업에서 품질이 더 많이 개선되었음을 보여 준다. This paper analyzes changes of export prices and product quality in Korean exports using Korea's HS 10 digit trade data during 1992~2008. For this purpose, we calculated the number of products whose export prices are higher than import prices, and estimated quality index using unit value and volume of exports. The results show that the ratio of higher quality products to all products has increased over time, and quality index has also increased during the period. It implies that the quality of Korean exports has improved. In particular, the quality improvement is highest in machinery and transportation industry (SITC 7), and the quality in high technology industries has increased faster than that in low technology industries. Finally, quality improvement is higher in the industry with larger trade volume.
