In Korea, fishery managers, eco-labeled program operators, and the government need detailed information regarding individual-level preferences for eco-labeled seafood. This study aims to identify the determinants of consumer preference for such seafood. Specifically, an ordered probit model is estimated by using micro-survey data obtained from interviews of 2773 randomly selected Korean households. Overall, the estimation results reveal that the chosen model is appropriate to analyze consumer preference for eco-labeled seafood. The coefficients of consumption frequency, the importance of price, the confirmation of origin, residential area, and household income are statistically meaningful. If consumers consider price an important factor, their consumption of eco-labeled seafood may decrease. Moreover, consumers with interest in the origin of seafood are more likely to accept eco-labeled seafood. To increase the consumption of eco-labeled seafood, it is recommended to develop products designed specifically for segmented markets and promote functional features. The findings can provide a valuable guideline to marketing managers and policy makers for designing effective strategies regarding eco-labeled seafood.

As smart technology in the shipping industry accelerates, demand for technology development, which aims to increase competitiveness by utilizing the latest smart technologies, is increasing. The shipping industry in each country is pushing for developing its smart technologies at a rapid pace, and it is urgent to prioritize the demand for smart technologies in the shipping industry for sustainable industry growth. The purpose of the present study is to verify the importance and urgency of smart technologies in the shipping industry, and the present study surveys 74 domestic and foreign shipping industry officials, covering shipping companies, brokers, governments, etc. The importance and urgency of each smart technology item in the shipping industry are questioned in a survey. It is necessary to focus investment on specific smart shipping items under a limited budget, and, since the priorities presented in this study were derived through comprehensive collection of opinions from 74 shipping experts, the priorities presented in this study are expected to be effective reference values when implementing sustainable shipping investment policies. According to an interview analysis on importance and urgency, both “autonomous ships” and “blockchain” items show high importance and urgency. Since both importance and urgency are high, strategic priorities are the highest, and it is expected to contribute effectively to enhancing the smartness of the shipping industry when it focuses its investment capabilities in those fields.

Under the new climate regime, renewable energy (RE) has received particular attention for mitigating the discharge of greenhouse gas. According to the third energy master plan in South Korea, by 2040, 30–35% of the energy demand must met with RE sources. To ensure relevant policy design to achieve this goal, it is crucial to analyze the public’s willingness to accept community-based RE projects. This study conducted a nationwide survey to understand the opinion of the public and also that of local inhabitants living near a RE project. A choice experiment was employed to measure public preferences toward RE projects. The analysis reveals that the type of energy source, distance to a residential area, and annual percentage incentives could affect acceptance levels. Additionally, investment levels were a factor in local inhabitants’ acceptance of energy-related projects. This study presents the relevant policy implications in accordance with the analysis results.
