In addition to simply providing quality food to the people, the fishery industry must be maintained and developed because it has various functions such as national food security, preservation of natural scenery, protection of national territory, and revitalization of the local economy. However, risk factors such as climate changes and environmental destruction have raised concerns about the sustainable development of the industry. Since these risk factors are becoming larger and more complex over time, it is time to conduct research related to the risk of the fishery industry. Therefore, the purpose of this study is to explore the risk factors facing the fisheries at this point, to analyze the economic ripple effect of regional fishery product supply shortage, and to draw implications. As a result of this study, the economic ripple effect of fishery product shortage per won was highest in Busan, followed by Gangwon, Gyeongnam, and Gyeongbuk. Considering the size of the local fishery industry, Busan had the highest supply shortage per 1% of local fisheries production. It is also necessary to prepare special risk management and countermeasures for these regions since the effect of supply shortage in regions such as Jeonnam, Gyeongnam, and Jeju is large compared to other regions.

이 논문의 목적은 2020년 11월에 타결된 역내포괄적경제동반자협정 (RCEP)에 한국, 중국, 일본이 참여한 각각의 요인들과 인도가 가입하지 않은 요인들을 구체적으로 분석하여 국제레짐이론의 시각에서 설명하는 것이다. 첫째, 한국이 가입한 주요 요인은 신자유주의 이론의 설명대로 교역의 확대를 통한 경제적 이득을 예상했기 때문이다. 또한 신현실주의 이론에서 예상하듯이 아세안과의 포괄적 협력을 강화하여 역내에서 한국의 상대적 지위와 영향력을 높이려는 의도에서 비롯되었다. 둘째, 중국이 RCEP에 가입한 주요 요인도 경제적 이득인데 이는 신자유주의 이론의 설명과 부합된다. 또한 신현실주의 이론에서 예상하듯이 중국은 역내에서 주도적으로 다자적 통상협력의 틀을 구축함으로써 기존의 지위와 영향력을 증대하려는 것이다. 셋째, 일본도 신자유주의 이론이 예상하듯이 주로 경제적 이득을 고려하여 RCEP에 가입하였다. 또한 RCEP을 통해 수준 높은 다자적 자유무역 질서를 확립하는데 리더십을 발휘하기 위함이다. 이러한 요인은 신현실주의 이론으로 설명된다. 반면에 인도가 RCEP에 가입하지 않은 주요인은 중국에 대한 상대적인 경제적 손실이 예상되어 자국의 상대적 지위와 영향력이 저하될 것을 우려하였기 때문인데 이러한 요인은 신현실주의 이론에 의해서 적절히 설명된다.

The objective of this study was to identify the effects of various environmental effects associated with performance testing results in pig population of domestic pig breeding farms. Performance test data collected from 2,000 to 2,010 were a total of 265,901 heads. By breeds, data consisted of Duroc, Landrace and Yorkshire. Environmental factors considered in models were breed, sex, farm, year of test, season of test, and parity. Broad range of age at testing day averaged at 155 days of age were grouped as A (up to 140 days) B (141~150 days), C (151~160 days), D (161~170 days), and E (greater than 170 days). Traits analyzed were ADG, days to 90 ㎏, end weight (body weight at the test day), rib eye area, back fat thickness. Age group effects were all significant for all the traits studied (p<0.05). As ages at test day get greater, ADG, days to 90 ㎏ and end weight tended to be greater while ultrasound measures of rib eye area and back fat thickness tended to be less. This would be the results of linear age adjustments on ultrasound measures, that caused overestimation in younger age groups and underestimation in older age groups than in average age group (C). This was evidenced by looking at ultrasound measures before linear age adjustments were applied. We conclude that, for more accurate performance testing, testing within guided age interval should be abided. And further researches should be made on biologically justifiable methods of age adjustments especially for ultrasound measures.

The primary purpose of the study is to investigate the volatility spillovers from global economic policy uncertainty and macroeconomic factors to the Islamic stock market returns. The study focuses on the Islamic stock indices of emerging economies including Indonesia, Malaysia, and Turkey. The Macroeconomic factors are industrial production, consumer price index, exchange rate. EGARCH model is employed for investigation of volatility spillovers. The results show that the global economic policy uncertainty has a significant spillover effect only on the returns of Turkish Islamic stock index. Similarly, the shocks in macroeconomic factors have little influence on the volatility of Islamic indices returns. The volatility of Indonesian and the Turkish Islamic stock indices returns is not influenced from the fluctuations in macroeconomic factors. However, there is significant volatility spillover only from industrial production to the returns of Malaysian Islamic index. The results suggest that the Islamic stock markets are less likely to influence from the global economic policies and macroeconomic factors. The stability of Islamic stocks provide opportunity for diversification of portfolios, particularly in stressed market conditions. The major price factors of Islamic markets could be firms’ specific factors or investors’ behaviors. The findings are helpful for policy makers and investors in formulating policies and portfolios.

This paper analyzes factors affecting corporate investment decisions in economic groups listed on the Vietnam stock market. The panel data of the research sample includes 39 economic groups listed on the Vietnam stock market from 2009 to 2019. The Generalized Least Square (GLS) is employed to address econometric issues and to improve the accuracy of the regression coefficients. In this research, the investment rate is a dependent variable. Cash-flow (CF), Investment opportunities (ROA), Fixed capital intensity (FCI), Leverage (LEV), Sales growth (GR), Size (SZ), Business risk (RISK) are independent variables in the study. The model results show that cash flow and sales growth have the same impact on investment decisions of economic groups in Vietnam. In addition, investment opportunities have a negative impact on the capital investment decisions of economic groups. The remaining factors include fixed capital intensity, leverage, firm size, and business risks that have a weak and insignificant impact on capital investment decisions of economic groups in Vietnam. The findings of this article are useful for business administrators, and helping business managers make the right financial decisions. Besides, the research results are also meaningful to money management agencies. The authors recommend that the State Bank of Vietnam should maintain a sustainable monetary policy.

This study aims to determine the factors influencing the community behavior in improving competitive rural tourism as well as understanding the role of economic literacy in mediating socio-economic indicators and rural competitive advantage. This research followed an explanatory research to examine the relationship between variables including socio-economic variables and rural tourism competitive advantage. The data was gathered by conducting observations and interviews with tourism businesses, stakeholders, and the local village government, and related agencies as respondents. Furthermore, the data were analyzed following inductive and descriptive statistics. The findings indicated that, from all variables used, solely the environmental impact variable did not affect economic literacy and the competitive advantage of rural tourism. The moderating variables showed that the economic literacy mediates the economic impact on rural tourism competitive advantage. In addition, socio-cultural impacts on rural competitive advantage tourism, and the stakeholder involvement affects rural competitive advantage tourism. However, economic literacy failed in mediating between environmental impacts on rural competitive advantage tourism. This is due to the increasing understanding of the economy of the community around the tourist attractions it will increase the business around the tourist attractions that have an impact on environmental damage around the tourist attractions.

This research aims to generalize the conceptual basis of precariousness of employment, study the factors and scale of unsustainable of employment in the countries of the Eurasian Economic Union (EAEU). The concept of precariousness of employment is formed in social and economic studies about 40 years ago, but objective and subjective conditions and forms of unsustainable employment existed before. This study proposes a classification of forms of precariousness of employment on 16 criteria: the duration and timing of agreements, contract terms, the nature of income; the degree of labor autonomy; the level of formality; the level of openness; the level of vulnerability; the conditions of growth of qualification; the level of flexibility; the level of stability; regularity; the severity of the danger of work; in relation to the workplace; the quality of employment, the level of social security. In this research highlighted factors (globalization, demography, migration, structure factors, shadow and informal economy, social development and living standards, unemployment), and systematized certain trends of precariousness of employment, channels and means, forms of manifestation. The empirical analysis identified of the labor potential of the Eurasian countries and new quantitative estimates of the levels of unsustainable employment in the Eurasian Economic Space.

This study analyzed whether there are mediating effects of government policies between the inputs and the economic performances of Korean bioenergy companies-this was accomplished by applying a mediating analysis by PROCESS Macro ver 2.16.3 (Hayes, 2013) based on a survey from the bioenergy companies. The analysis found that the increase in inputs of the Korean bioenergy companies affected the increase of performance through the government policies. In addition, comparing the mediating effects of detailed policies, this study found that said effects were greater in the order of RPS(Renewable Portfolio Standard) > the price variation of electricity = the obligation of greenhouse gas reduction > the changes in business scale based on RPS·RFS(Renewable Fuel Standard). However, it was found that the price variation of transportation fuels and RFS did not make a significant difference. There are two political implications of this study. First, to enhance the economic performance of bioenergy companies, the Korean government should keep the expanding trend of the current RPS. Second, the government needs to emphasize the importance of biofuels for transportation and make policies to develop related industries.

The aim of the study is to assess the asymmetry of influence of factors of economic growth of national economies, which are included in the integration. Unlike previous research, the scientific significance of the obtained results consists in the use of a new method of study – external demand as a factor of economic growth, disaggregated into two components. The first is net exports mutual trade in goods within integration associations. The second is net exports of foreign trade in goods outside the integration. By use of these methods we have evaluated the contribution of these factors on economic growth of the Customs Union and the Common Economic Space (CU/CES), as well as Kazakhstan, Russia and Belarus. In the conducted analysis of scientific research was based on the fact that the economies of the member (CU/CES) are very different in scale, economic potential and volume of foreign trade. Based on this research we conclude: integration is developing successfully and efficiently only with the rise of the national economies of the member countries; to enhance economic growth and competitiveness of the countries of the Eurasian integration it is necessary to increase the volume of mutual trade of member countries of this integration.
