This study intends to help find new trade structures and directions to break the problem, by comparing Korea with the Netherlands, which has similar characteristics with Korea. Design/methodology/approach: This study applied the competitive import model and used data from World Input-output Data(WIOD), and focused on Information and Communications Technologies(ICT) manufacturing and ICT service industries as the key industries in Korea, and chemical and medical industries as the key industries in the Netherlands. Findings: The results indicated that Korea's ICT manufacturing and chemical industries have high backward linkage effect, while the Netherlands' ICT manufacturing, ICT service, and medical industries have high forward linkage effect. Research limitations/implications: When comparing between industries, it is clearer to consider not only the effect of generating production but also the creation of value added and the creation of employment in order to directly compare differences. As a contribution, comparisons between countries with large-scale trade were found to require the use of competitive models over non-competitive ones. Originality/value: This study showed that competitive analysis model should be used instead of non-competitive import model when Input-Output(IO) analysis is applied to countries with a high proportion of intermediary trade.

The results showed that there is a different mechanism in uT adoption between pre-adoption and post-adoption. And uT in Korea is now in chasm phase.

Specifically, this study investigates whether the Internet consumer characteristics affect the two dimensions differently. The results show that the Web purchase suitability partially mediates the effects of the internet consumer characteristics on online purchase intention.

Among them, Twitter, Google, iPhone, and Secondlife (T.G.I.S) are the most popular services/products these days. To measure the adoption of these product/services, the most commonly used are IP traffic

However, it diminishes as time passes. Conversely, the imitation effect becomes a more powerful factor for the early majority, late majority and laggards. The imitation effect in the ICT industry is greater than that in the non‐ICT industry, revealing the high network effect in ICT diffusion.Research limitations/implicationsMobile phones are not the representative of all ICTs as the automobiles also do not represent all utility products. More ICT and conventional products need to be included and compared for greater generalization of the results from different countries.Pra...

This study consists of a SWOT (Strength, Weakness, Opportunity, Threat) analysis from the literature review and in-depth interviews with experts of the beauty service industry in South Korea. The Analytic Hierarchy Process (AHP) is applied to the finalized SWOT matrix to incorporate experts’ ideas. The combined high priority factors present four types of strategic alternatives: Strength–Opportunity (SO), Strength–Threat (ST), Weakness–Opportunity (WO), and Weakness–Threat (WT). This study applies an environmental analysis framework from the management strategy field to construct a sophisticated SWOT matrix. Furthermore, this study quantifies the importance of SWOT components through AHP to determine priorities to lay the groundwork for timely and sustainable strategy development in the beauty service industry. Based on the SWOT-AHP analysis, this study...

The results showed the detailed industrial linkage effects of the logistics service industry, indicating several logistics sectors (transportation, storage, and handling) are not only interdependent but they also form a service ecosystem. The study results provide new insights on industrial linkage effects of the logistics service industry and their ripple effects throughout the economy. The results will be valuable source of knowledge for establishing service industrial policies for both the logistics industry and a country's economy as a whole.

This study used the Trade-off model and Diffusion of Innovation theory to statistically examine the trilemma phenomenon in the global smartphone market and revealed that during the early stage of market entry, a company should actively source and use bigmouth consumers and killer app developers, invest limited resources to expand its target market with the aim of sales profits, and develop specifically for innovation. Starting from the later stage of its market growth period, a company should establish some alternative strategies for responding to the possible reduction in the efficacy of marketing expenses.

ICT industry was classified into ICT manufacturing and ICT service sectors on the basis of the taxonomic definitions provided by Organisation for Economic Co-operation and Development (OECD). Data were collected from World Input–Output Database (WIOD) ranging from 2000 to 2014 in order to quantitatively estimate the forward linkage (FL) and backward linkage (BL) effects. This study then used Leontief’s IO models to compute the FL and BL effects of ICT manufacturing and ICT service of Korea and India. Thereafter, four separate univariate analyses of variance were performed to statistically test the research hypotheses developed based on literature review and conceptual framework. The results of the study revealed that (1) an industry with competitive advantage had a higher FL effect and (2) a catch-up growing industry had a higher BL effect. In conclusion, ICT manufacturing and service sectors between Korea and India have very different characteristics and effects on each national economy.

This study uses input–output (IO) table to examine the industrial impact and competitive advantage of the ICT industry in China from 2002 until 2012. We concluded that (1) the ICT industry has partially higher industrial impact and competitive advantage over the non-ICT industry. The results of this study imply that promoting the ICT industry could help boost China’s economy, and investing offered possibilities for gaining more benefits compared to the non-ICT industry.

By using sentiment and survival analysis, this study classified 1,038 movies according to the customer comments and movie characteristics and compared the number of screening days, the primary measure of success of movies, between the groups. Based on the analysis of film reviews (i.e., positive, negative, and neutral), screening days showed significant differences between (1) the positive and neutral groups, negative and neutral groups, (2) the density (|positive-negative comments|) of the positive and negative groups, (3) drama and action, drama and comedy, (4) domestic and foreign films, (5) GRated and R-Rated, R-Rated and X-rated films.
