VHVI 수첨분해 기유는 자동차와 산업분야에서 시장을 형성하고 있다. VHVI 기유에 대한 응용분야로 큰 시장으로서 산업용 초 고점도지수 유압작동유로의 응용분야가 있긴 하지만 본고에서는 모터오일에 집중하여 설명하였다. 고점도지수 유압작동유는 현재 전통적인 파라핀계 기유에 점도지수 향상제로서 배합, 제조되고 있다. BP사와 Shell사는 윤활유 시장에 VHVI를 배합하여 제조된 이런 유형의 제품을 시판하고 있다. 이런 경우에 초 고점도지수 윤활기유의 사용으로 한가지 잇점을 찾을 수 있다. 생산 원가에 있어서의 제한된 상승에 기인하여 마찰안정도를 향상시키기 위한 점도지수 향상제의 사용에 있어서의 한계가 있다는 점이다. 과연 정말로 Union-Fuchs사는 이런 형태의 응용목적을 위한 분야의 대부분의 그들의 제품에 이러한 VHVI기유를 사용하고 있다. VHVI기유의 다른 분야로의 응용은 기술적으로 관심은 있으나 그 시장점유율이 매우 낮다. VHVI기유의 주된 생산자인 Shell사와 BP사는 최근 경쟁 윤활유 제조사에 이 VHVI기유를 제공, 공급하고 있다. 이것은 확립된 합성유 시장에 대한 도전이 될것으로 사료되며 도전이 되어야 한다.

This study investigates changes of market structure from 2001 to 2015 in the Korean daily newspaper industry using concentration and mobility measures. The main empirical results are as follows. First, the industry's total asset shows a U-shaped trend, despite the downward trend of the industry's total sales revenue. Second, the market concentration, measured in terms of assets, shows the trend of an inverted-U shape. The relatively small firms, measured in terms of assets, have on average gained in market share while the relatively large firm have lost. Third, market concentration, measured in terms of sales revenues, shows a U-shaped trend. the relatively small firms, measured in terms of sales revenues, have on average gained in market share while the relatively large firm have lost. My central argument has been that it is desirable to supplement traditional concentration measures with mobility statistics and trend analyses in investigating and regulating market structure.

This paper examines the export structure of Gwangyang Port and evaluates its comparative advantage from 2005 to 2016 using the Comparative Advantage by Countries (CAC) index. It is found that: (i) Gwangyang Port has a comparative advantage in HS 39 and HS 28, an unstable comparative advantage in HS 29 but a comparative disadvantage in HS 72; and (ii) 4 items have the common features of losing their comparative advantage. Constant market share analysis allows one to evaluate why the exports of one region may grow faster than world exports. This consists of the commodity composition effect, the scale effect, and the competitive effect. Constant market share analysis shows that the commodity composition effect influences exports negatively while the scale effect does exports positively. Shift-share analysis can help evaluate the change in a region's performance relative to the nation over a given period of time. The result indicates that HS 28 has not only favorable industrial mix effect but high competitive share effect, while HS 29 has unfavorable industrial mix effect as well as low competitive share effect. This paper also reveals that industrial mix effect of HS 39 is positive but its competitive share effect is negative, whereas the former is negative but the latter is positive in case of HS 29.

This study aims at analysing the export competitiveness of the six largest countries which have the highest market share in world automobile market, namely Japan, USA, China, Germany, South Korea and France for the last seven years between 2000 and 2006 in Chinese automobile market by using revealed comparative advantage index(RCA), comparative advantage index by country (CAC) and exporting similarity index(ESI). On analysis of the RCA index, it showed that the export competitiveness of Korean automobile in the world market was high following Japan and Germany, but it ranked the lowest competitiveness among the six trade competitors in Chinese automobile market. In other side, it is also made sure that the formidable competitors of Korean automobile export in global market are Germany and Japan. Therefore, South Korea needs to raise its ability to adjust to improvement of the international competitiveness in exports through close cooperation between government and automobile export enterprise and consistent monitoring about Chinese automobile industry and market.

This study empirically examines the impact of changes in market shares among retailing types on the price index. The retailing type is classified into 6 groups: department store, big mart, super market, convenient store, specialty merchant, and on-line store. The market shares of retailing types are calculated by the ratio of each retailing type monthly sales to total monthly retailing sales in which total retailing sales is the sum of each retailing type sales. We employed several price indices: consumer price index (CPI), CPI for living necessaries, and fresh food price index. In addition, this study used fundamental price indices based on 25 product families as well as 42 representative products. The empirical model also included several variables in order to control for the macroeconomic effects and those variables are the exchange rate, M1, an oil price, and the industrial production index. The data is monthly time-series data spanning over the period from January 2000 to December 2010. In order to test for the stability of data series, we conducted ADF test and PP test in which the model and length of lag were determined by the relevant previous literature and based on the AIC. The empirical results indicate that changes in market shares among retailing types have impacts on the price index. Table A shows that impacts differ as to which price index to use and which product families and products to use. For department store, it lowers the price of food and non-alcoholic beverages, home appliances, fresh food, fresh and vegetables, but it keeps the price high for fresh fruit. The big mart retailing type has a positive impact on the price of food, nut has a negative effect on clothing and foot wear, non-food, and fresh fruit. For super market, it has a positive impact on food and non-alcoholic beverages, fresh food, fresh shellfishes, but increases the price of CPI for living necessaries and non-food. The specialty merchant retailing type increases the price level of CPI for living necessaries and fresh fruit. For on-line store type, it keeps the price high for CPI for living necessaries and non-food as well as fresh fruit. For the analysis based on 25 product families shows that changes in market shares among retailing types also have different effects on the price index. Table B summarizes the different results. The 42 representative product level analysis is summerized in Table C and it indicates that changes in market shares among retailing types have different effects on the price index. The study offers the theoretical and practical implication to these findings and also suggests the direction for the further analysis.
