  • In this study, the volume of Pohang Port was predicted. All cargo of Pohang port, iron ore, steel, and bituminous coals were selected as prediction targets. SARIMA, Prophet, and Neural Prophet were used as analysis methods. The predictive power of each model was verified, and a predictive model with high performance was used to predict the volume of goods in Pohang port. As a result of the analysis, it was found that Neural Prophet showed the highest performance in all predictive power. As a result of predicting the future volume of goods until August 2027 using Neural Prophet, it was found that the volume of all items in Pohang port was decreasing. In particular, it was analyzed that the decline in steel cargo was steep. In order to increase the volume of cargo at Pohang port, it is necessary to diversify the cargo handled at Pohang port and check the policy of increasing the volume of cargo.

  • This study is designed to investigate the effect of inflow FDI on the host country's economic growth and the role of absorptive capacity in this relationship. Eight developing countries in East Asia, including Mongolia, Indonesia, Malaysia, Myanmar, the Philippines, Thailand, Vietnam, and Cambodia, are analyzed. Year data from 2000 to 2018 are used. Based on the study of Hansen (1999), the panel threshold effect model is used, and human capital, R&D, and infrastructure are set as absorptive capacity by referring to Wang and Hwang (2013). The analysis results are as follows. It is confirmed that FDI has a positive effect on the economic growth of the host country, and absorption capacity strengthens the relationship between FDI and economic growth in a positive direction. At this time, it appears that a threshold exists for the moderating effect of the absorptive capacity. It presents useful implications for economic growth in developing countries.

  • In Korea, the road transport industry is pointed out as a major cause of air pollutants, so management control is needed. Existing studies used only positive input and output variables to measure regional efficiency. However, it is necessary to consider the environmental pollution problem in efficiency analysis. In this study, an undesirable SBM analysis using CO2 was conducted to measure efficiency of domestic regions. In addition, SDM was conducted to examine the ripple effect between domestic regions. As a result of the analysis, the efficiency of the capital area such as Seoul, Gyeonggi, and Incheon was high in the road transport industry. However, the efficiency of the road transportation industry in Daegu and Gangwon was low. In the SDM analysis, it was found that the regional equipment capabilities had a great influence on efficiency. In order to improve efficiency, it is necessary to increase and improve the equipment capacity of the road transport industry.

  • This study investigates the impacts of international trade and foreign direct investment (FDI) on income distribution both nationally as well as provincially in Vietnam. This study uses panel data of 63 provinces in Vietnam for the period of 2008-2016 and a time series dataset from 1992 to 2016. We found the following results. First, the income distribution is significantly affected by per capita income. When we consider the Kuznets hypothesis, the intra-provincial income inequality of Vietnam's 63 provinces follows a regular U-shaped relationship. In contrast, the income distribution in Vietnam exhibits an inverted U-shaped relationship between the Gini coefficient and per capita income. Second, the inward FDI tends to reduce income gaps in each province through the employment of predominantly low-skilled workers. FDI, however, seems to increase income inequality throughout Vietnam. This result is potentially due to the strong concentration of FDI into a very few areas. Third, the effect of trade openness exhibits a decrease in inequality both within each province and in the whole country of Vietnam.

  • This study investigates the structural relationship among 11 latent factors that potentially influence the intention of Chinese consumers to purchase electrical vehicles (EV) by applying the MGB and TAM models, both based on well-established socio-psychological theories. For this research, we conducted an online survey using a Chinese platform collecting 287 valid responses to our questionnaire. The analysis reveals that 10 out of the 12 hypotheses were adopted while 2 were rejected. Specifically, it was found that EC (environment concern) and PEV (perceived environment value) had a positive effect on the PEU (perceived environmental usefulness) of electric vehicles. In addition, ATT (attitude), PAE (positive anticipated emotion), and PBC (perceived behavior control) were confirmed to have a significant positive relationship with DES (desire) for EV purchase. At the same time, the results of the analysis show a statistically significant relationship between PEU, ATT as well as PI (purchase intention). This study further analyzed and presented the results of the moderating effects of gender, based on the adopted relationship hypotheses. This study is novel in that it is the first attempt in the literature to apply both the MGB model and the TAM simultaneously to predict EV purchasing behavior.

  • This study analyzes the effects of FDI on the global value chain (GVC) using participation and export value added using panel data from 2005 to 2016 for 63 countries. This study used the GLS method. Results are as follows: First, foreign direct investment had a positive impact on the global value chain (GVC) participation and export value added of non-OECD economies. Furthermore, tariff rates were more sensitive to non-OECD countries than OECD countries. In addition, logistics infrastructure had a negative impact on global value chain (GVC) participation and export value added, while developed countries, such as OECD countries, with good infrastructure, had a positive impact on non-OECD countries. Finally, research and development costs have been shown to play a very important role in non-OECD countries. This study found that various service sectors, such as research and development (R & D) as well as the general manufacturing industry, are expanding beyond two countries to form global value chains (GVC) in which several countries are connected from production to consumption.

  • Recently, each country has been using non-tariff barriers (Non-Tariff Barriers, NTB) as a new protection trade policy. In particular, TBT lies at the center of NTB. In this context, we examine the impact of Technical Barriers to Trade (TBT) on Korea's exports to ASEAN. Using 10-year statistics from 2007 to 2016 that came into effect with the ASEAN FTA, we analyze the impact of TBT on the Korean exports in the electrical machinery industry (HS85), which accounts for more than 30 percent of Korea's total exports to ASEAN. The results of the empirical analysis using a gravity model showed significant and positive effects in the variables of GDP and real effective exchange rate in each ASEAN country on Korea's exports to ASEAN. As expected, the tariff rate has a negative effect. As for TBT, the key variable of this study, the results are as follows. Although many previous studies reported that TBT has negative impacts on exports, this study could not find any significant impact of TBT and found that Korea's exports of electrical machinery to ASEAN countries are not affected by TBT. Various implications of these results are suggested.

  • This study aims to investigate the determinants that can influence customer satisfaction and loyalty. Compared to some of the determinants that have been investigated by other scholars before, this study also includes a new approach to mobile food-ordering that has only appeared within the Chinese fast-food industry in recent years. It is very important to test if the convenience of mobile ordering services can influence customer satisfaction, as more and more customers are using mobile apps to order food, especially in the 4th Industrial Revolution Era. Research data mostly was collected from customers who visited one of five famous Western fast-food restaurants (KFC, McDonald's, Pizza Hut, Subway, and Burger King) in China. The results show that not only price, service quality, food quality, and the physical environment can significantly affect customer satisfaction but also the convenience of mobile ordering services, a new determinant accompanied by the fast development of IoT technology.

  • This study aims to explore the positive impact of Korean drama watching satisfaction on purchase intention for Korean products by considering the mediating roles of social distance to Korea, national image of Korea, and Korean product image. This study identified that Korean drama reduced the social distance to Korea while increasing the positive image of Koreas and Korean products. However, the reduced social distance was not positively associated with Korean product image and Korean product purchase intention. This implies that Korean dramas directly affect Korean product purchase intension and indirectly affect Korean national image and product image. This study supplies guidance to international marketers who aims to enter the Myanmar market. To use the Korean wave as a Korean product marketing tool, marketing strategies need to cover Korean culture-relevant materials such as cultural background, cultural characteristics, exposed products, and so on.

  • This study compares and analyzes the effects of GVC participation on export competitiveness in manufacturing and service industry in 36 OECD countries and 28 non-OECD countries. According to the statistical analysis result, the GVC participation had a negative impact on export competitiveness in manufacturing industry, while it had a positive impact in the service industry. In the case of the manufacturing industry, participation toward the backward GVC had a positive impact on export competitiveness before the financial crisis, besides, participation toward the forward GVC had a positive impact on export competitiveness. In the case of the service industry, export competitiveness through forward GVC participation has increased since the financial crisis has occurred, and backward GVC participation was estimated to have a negative impact on export competitiveness. The results of this study implies that, to secure export competitiveness, a converged approach of the manufacturing and service industries to upgrade the global value chain is needed.
