Successful market adoption of rail freight transport innovations that might offer opportunities for market share increase is the focus of this paper. Firstly, seen from a theoretical point of view, it is not incremental innovations but radical organizational and transformation innovations that are likely to increase the market share of rail freight transport. Secondly, the particular inovations that offer some success potential for market adoption are: dedicated infrastructure, the fixed timetable, locomotive upgrades, and INTERFACE. Thirdly, unfortunately, the opportunities to increase the market share of rail freight transport appear to be limited.

Google Trends is a useful tool not only for setting search periods, but also for providing search volume to specific countries, regions, and cities. Extant research showed that the big data from Google Trends could be used for an on-line market analysis of opinion sensitive products instead of an on-site survey. This study investigated the market share of tumor necrosis factor-alpha (TNF-α) inhibitor, which is in a great demand pharmaceutical product, based on big data analysis provided by Google Trends. In this case study, the consumer interest data from Google Trends were compared to the actual product sales of Top 3 TNF-α inhibitors (Enbrel, Remicade, and Humira). A correlation analysis and relative gap were analyzed by statistical analysis between sales-based market share and interest-based market share. Besides, in the country-specific analysis, three major countries (USA, Germany, and France) were selected for market share analysis for Top 3 TNF-α inhibitors. As a result, significant correlation and similarity were identified by data analysis. In the case of Remicade's biosimilars, the consumer interest in two biosimilar products (Inflectra and Renflexis) increased after the FDA approval. The analytical data showed that Google Trends is a powerful tool for market share estimation for biosimilars. This study is the first investigation in market share analysis for pharmaceutical products using Google Trends big data, and it shows that global and regional market share analysis and estimation are applicable for the interest-sensitive products.

This paper analyzes changes in the export potential and competitiveness of China, Japan, and Korea. The analysis of Japan's export market share reveals that in sectors where Korea's potential was strong in the early 1990s, Japan's market share diminished. This suggests the possibility that Korea was catching up with Japan, eating into Japan's market share. The same analysis of Korea's export market share in the 2000s shows, for items in which China's export potential was high, Korea's market share has declined comparatively since 2010, with the tendency growing much larger. China's export potential continues to expand in markets for Korea's key export products, making it difficult to rule out the possibility that Korea's competitiveness in key export products will be hindered, driven by the catching up of China. To respond to these challenges, it is important for Korea continuously to foster and enhance creative and core capabilities that latecomers will not easily be able to emulate.

Starting with the meaning of the word quality, diverse concepts connoted by the term are examined. Instead of a bathtub curve, the desirable shape of a failure rate covering the entire life of a good product, which might be called hockey-stick line, is introduced. From the hockey-stick line and the definition of reliability, two measurements are extracted. The terms reliability, failure rate, product life, and durability are explained. From the customer's standpoint, the concept of product quality is classified in five factors, according to related technology: performance, reliability, conformance to specifications, customer perception, and fundamentals advantage. The correlation of the five factors for a first-class product is discussed, Since the market share of a company is determined as the competition result of its product value, defined as product quality and price, the market share increase is derived mathematically from the increment of product value. The market share increase, $\Delta$S, can be calculated from the present market share, S, and the oriented relative value increment of new product, R, to the current product in the same company for the same market target: $\Delta$S : $\Delta$(1-S). R/(1+S.R). Finally, the importance of separating warranty cost from the profit equation for the durables is explained.

The purpose of this paper is to understand the underlying dynamics for the share market bubbles in China during the most recent decade. By using the behavioral finance theory and the Shanghai Composite index prices during the periods from 2005 to 2008 and from 2014 to 2015 as the study samples, we find that the large volatilities in the Chinese share market are closely related to information blockage, which impedes share prices to timely respond to economic conditions as well as external shocks and increases (decreases) the demand of shares when the supply is difficult to adjust. Although the Chinese government has introduced a series of programs designed to increase more reliable information to the public, the share market still tends to confront issues of information asymmetry. The potential reason is that the reforms did not change the long-stand situation in China, where individuals or groups related to government bureaucracy who play a dominant role in the society are given priority to gain access and obtain information that benefits. By identifying the main reasons for the large volatilities in the market, policy makers are given advice as to which areas they may need to focus on to improve future market performance.

The purpose of this research is to evaluate Brand Value by using the K-BPI(Korea Brand Power Index) of Korea Management Association which is based on consumer awareness, as well as to identify how Brand Value which is composed of top of awareness, unaided awareness, aided awareness, image, possibility of purchasing, preference, affects on the Market Share perceived by consumers. This research subjects were 10 hospitals with more than 1,000 beds in Seoul and Gyeonggi-do, and survey subjects were 20 or older adults living in the metropolitan area of Korea. Using K-BPI for measuring Brand Value and used calculation of Market Share according to consumer preference model for measuring Market Share. The major results of this research are as follows: First, this research identified that the top 5 hospitals of largest hospitals in metropolitan area measured by using K-BPI and Market Share were same hospitals as Big 4 hospitals of previous research evaluating the comprehensive competitiveness of hospitals and also same as hospitals that appeared recently. Second, Big 5 hospitals ranked first to fifth in both Brand Value and Market Share. To identify the relationship between K-BPI items(top of awareness, unaided awareness, aided awareness, image, availability, preference) and Market Share, multiple linear regression was used by dividing 5 upper and 5 lower group of hospitals per each. The group of 5 upper hospitals had a significant effect on Market Share, with 'top of awareness', 'unaided awareness', 'aided awareness'. The group of 5 lower hospitals had a significant effect on Market Share with 'unaided awareness', 'aided awareness'. The results of this study and hospitals of the first to third hospitals published in the K-BPI press release reported by KMAC in 2017, and the previous studies evaluating the comprehensive competitiveness hospitals, all had one thing in common that Big 4 hospitals ranked high position. This suggests that evaluation of Brand Value also can be a evaluation measure of hospital. A new competitiveness of hospital is expected by managing brand awareness to have a brand competitiveness and by securing intrinsic Market Share of consumer to reach hospital use ultimately.

Recently, the Korea's economy concerns the second money crisis because of the rapid increase of the exchange rate. The Korea's economy which is very dependent on the foreign trade is more sensitive to the change of exchange rates. There are many literatures which analyze the effects of variations of the exchange rates on the secondary and tertiary industries such as the manufacturing industry and IT(Information Technology). But there have been no studies which try to figure out the effects of variations of exchange rate on the primary industries, especially, fisheries' industry. Therefore this paper tries to analyze the effect of price competition structure and the change of exchange rate on foreign fisheries exporting prices in Korea's fisheries import market. This study utilizes OLS(Ordinary Least Squares Analysis) for the analysis in the market of frozen yellow corvina, hairtail, angler fish which are major fisheries importable in Korea. The results show that the exporting country which has the highest market share is more sensitive to the change of the exchange rates itself than that of the other exporting countries' price when it starts to set up its exporting price. And the exporting countries which have low market share are more sensitive to the change of price which country has the highest market share than that of price whose countries have low market share and those of their exchange rate. Also we can find out that the countries which have similar market share try to set up price-setting strategy in the opposite direction. In other words, one country tries to bid up its price, other countries response to rival country by lowering their prices. In the consideration of the fact that most exporting countries aren't affected by Korea's fisheries' prices, the exporting countries in Korea's fisheries import market are more sensitive to the prices of other exporting countries than that of Korea's. This result indicates that the price leader-follower model could be applicable to the Korea's fisheries import market.

This study investigates empirically the export competitiveness of Korea and Japan in America by calculating 4 indexes such as market share index(MSI), export similarity index(ESI), market comparative adventage index(MCAI) and market share expansion ratio(MSER)-export similarity deepening ratio(ESDR). The empirical finding of this analysis shows that Korea is competitive in the labor-intensive products and Japan in the technology-intensive products. This result also meets the general understandings that Japan is superior to Korea in the export competitiveness such as value added of goods, etc. Therefore, in order to strengthen the export competitiveness of Korea in the US market, it's desirable for our firms and government to improve the quality of product ranges by developing technologies focused on the higher value-added products.

Materials Industry has a very large ripple effect on national economic development. Nevertheless, Korea has been passing over importance of this Industry. So, this study examined competitiveness on ten chief exporting items to U.S.A market based on the understanding of vital role of materials industry in the national economy. Analyzing methods were Market Share, Trade Specialization Index(TSI), and Market Comparative Advantage(MCA) and the data were collected through parts and materials statistical data which produced by Korean Commerce and Industry Minister. From this study, following results were found. i) Highly ranked items of U.S.A market share were chemical fiber drapery weaving, synthetic fiber. These items commanded over 10% share of the same market and tire, steel wire occupied 9.05%, 8.65% respectively. ii) In searching trade balance aspects through TSI, tire and steel wire secured very powerful competitiveness among examined items in trading with U.S.A. while synthetic resins and other plastic material were very weak competitiveness in the same market. iii) Analysis results of market competitiveness by MCA, indicated that chemical fiber drapery weaving, synthetic fiber and tire ensured high-powered competitiveness in U.S.A Market. Therefore, these items would be positioned as main items in the market.
