This paper contains an introduction to industrial problems, solutions, and results conducted with the Korea Association of Machinery Industry. The client company commissioned the problem of upgrading the method of identifying global supply risky items. Accordingly, the factors affecting the supply and demand of imported items in the global supply chain were identified and the method of selecting risky items was studied and delivered. Through research and discussions with the client companies, it is confirmed that the most suitable factors for identifying global supply risky items are 'import size', 'import dependence', and 'trend abnormality'. The meaning of each indicator is introduced, and risky items are selected using export/import data until October 2022. Through this paper, it is expected that countries and companies will be able to identify global supply risky items in advance and prepare for risks in the new normal situation: the economic situation caused by infectious diseases such as the COVID-19 pandemic; and the export/import regulation due to geopolitical problems. The client company will include in his report, the method presented in this paper and the risky items selected by the method.

The purpose of this study is to identify problems and suggest improvements of estimating procedures and item of fisheries supply-demand statistics served as a basis for the fisheries supply-demand policies. Korea Rural Economic Institute(KREI) and Ministry of Oceans and Fisheries(MOF) respectively publish the fisheries supply-demand statistics. But the reliability of data is low as the statistics of these two organizations are limited and show discrepancy in the numbers. It is therefore difficult to use them as the basic data for policies. Also, an accurate data aggregation is difficult due to following problems in the items of statistics. 1) Problems in estimating route sales and non-route sales of production, 2) adequacy of fishery product yield rate compared to raw material in the fisheries import/export sector, 3) selection of target companies for understand stocks and survey scope of fish species, 4) applying'0'to non-edible product demand etc. In order to develop the fisheries industry as a future growth industry, it is necessary to establish the accurate fisheries supply-demand policy as the instability of fisheries supply and demand is increasing. To do this, statistical reliability has to be improved. The improvements proposed in this study should be implemented considering urgency. First of all, an exhaustive analysis of stock statistics and conversion rates of raw material yield in the fisheries import/export sector should be conducted. In the medium term and the long term, transferring production statistics to MOF and surveys on the use demand of non-food product and the level of reduced and discarded seafood products should be carried out in consecutive order.

South Korea imports more than one hundred tons of fishery products every year from China, Japan, North Korea, etc. However, imported North Korean fishery products was only 4% of the total fishery products imported in 2007. Though South-North Trade as inter-Korean trade is exempted from tax, imports of North Korean fishery products have not been activated owing to import restrictions, insufficient quality control etc. Expanding imports of North Korean fishery products seems, however, to contribute to lessen the supply and demand unbalance in fishery products of South Korea. It will especially gratify a part of fresh and cold fishery products demand. Therefore, we need to expand the imports of North Korean fishery products by quality control improvement, reformation of origin certifying system, import liberalization etc. This study researches the demand and supply of fishery products of South and North Korea, the actual conditions of imports of North Korean fishery products, and suggests strategies to expand their imports. As the greatest reason to oppose imports of North Korean fishery products is the pricing pressure of domestically produced fishery products due to imports of North Korean fishery products, we need to research and analyze the distribution channels, retail markets, sales prices of imported North Korean fishery products to verify that imports of North Korean fishery products has not caused lower pricing of domestically produced fishery products.

Import Agency Service Mall, providing customers not only with convenient shopping experiences but also with purchasing, warehousing, shipping, and customs clearance services, have been playing a significant role in rapidly transforming Korean consumers into global consumers. The consumers' great demand for foreign goods(services) has created Import Agency Service Mall(referred to hereafter as IASM) as a new business model of distribution and consumption, which seems to be grown rapidly. This empirical research investigates online shoppers for their trust dimensions for IASM. Consequences of the research are as follows: First, perceived reputation, web-site quality have influenced upon e-trust dimension of the IASM. Second, the level of e-trust consumers is more higher, and then the level of perceived risk is more lower. Third, perceived risk have not influenced upon intention to reuse the IASM. Fourth, the level of e-trust consumers is more higher, and then the level of intention to reuse the IASM is more higher. It is necessary for IASM to be developed its reputation and web-site quality in order to obtain customer's trust. Accordingly, this research will be helping IASM have insight for marketing strategies, and constantly should be studied about action and mind of consumer.

Objective : The study was for researching the activation methods about Korean overall medical crops business from 2010 to 2016. In addition, it was to be given to examining complement points and improving methods to the changeable domestic market of medical crops caused by a considerable export-import amount of them. Methods : By examining and analyzing data for the trend of medical crops production and their export-import trend from 2010 to 2015, I found it valuable to use it as the basic resources for researching the urgent problem of medical crops' business and its improvement. Results : 1. As surveying the trend of the domestic medical crops over the recent six years, I found that the export amount of them has drastically decreased, while the import amount has increased. And so, the prices of the domestic medical crops and their production are unstable. 2. By developing standardized medical crops which a trading counterpart country could prefer, we have to promote the export competitiveness. 3. We should reinforce an origin mark and geographical mark practice for domestic herbal materials and expand GMP. 4. We should prepare a standardization of herbal medicines by setting up an independent governmental department. Conclusion : 1. The government should present an appropriate supply-demand amount of the medical crops depending on the domestic needs and the export-import transactions. 2. There should be an institutional supportive system which is able to guarantee stable incomes of farmers through contract cultivation. 3. We should develop high value standardized medical crops.

본고(本稿)는 밀수(密輸)나 암시장(暗市場)(black market)과 같은 불법거래행위(不法去來行爲)가 발생(發生)하는 원인이 제한적(制限的) 수입정책(輸入政策)에 있다는 주장(主張)의 타당성(妥當性)에 대하여 분석(分析)하고 있다. 암거래상품(暗去來商品)과 합법교역상품(合法交易商品)이 똑같은 가격(價格)으로 거래되는 경우에는, 수입자유화(輸入自由化) 결과(結果)로 수입단가(輸入單價)가 하락하면 국내생산공급(國內生産供給)과 암거래(暗去來)가 감소하고 수입량(輸入量)이 증가하여 합법교역(合法交易) 암거래(暗去來) 대체효과(代替效果)가 발생한다. 그러나 암거래(暗去來)와 합법거래(合法去來)가 이원적(二元的)으로 운용(運用)되는 경우에는, 암거래상품(暗去來商品)과 합법교역상품(合法交易商品) 사이의 상대가격변화(相對價格變化)는 두 상품수요(商品需要)에 대한 대체효과(代替效果)와 소득효과(所得效果)를 유발한다. 따라서 수입가격하락(輸入價格下落)으로 합법교역상품(合法交易商品)의 상대가격(相對價格)이 하락하면 합법교역상품(合法交易商品)에 대한 수요(需要)가 증가하나 암거래상품(暗去來商品)의 수요(需要)에 대해서는 부(負)의 대체효과(代替效果)와 정(正)의 소득효과(所得效果)가 발생하는데, 대체효과(代替效果)를 소득효과(所得效果)가 상살(相殺)하는 경우에는 수입정책완화(輸入政策緩和)의 암거래억제효과(暗去來抑制效果)가 나타나지 않는다. 반면 직접적인 암거래규제강화(暗去來規制强化)는 암거래행위(暗去來行爲)의 위험비용(危險費用)을 증가시키므로 암시장가격(暗市場價格)이 상승하고 암거래행위(暗去來行爲)가 위축(萎縮)되는 효과(效果)가 발생한다. 이와 같은 결과는 제한적(制限的) 수입정책(輸入政策)이 유발하는 잠재적(潛在的) 초과수요(超過需要)뿐만 아니라 면세수입증가(免稅輸入增加)에 따르는 잠재적(潛在的) 초과공급(超過供給)이 암시장(暗市場)의 생성(生成)을 유발한다는 전제(前提)로부터 도출되었다.

인삼 한 뿌리 생산하지 않는 홍콩은 국제 인삼시장의 중심지 역할을 하고 있다. 전 세계 인삼 수출의 70% 이상을 취급하면서 또한 이를 주변 국가로 재 수출하여 국가의 부를 창출하여 왔다. 이러한 홍콩 국제 인삼시장에서 한국산 고려인삼의 시장 점유율 하락으로 고려인삼의 존재가 점점 희박해지고 있다. 이에 홍콩 국제 인삼시장에서 한국산 고려 인삼과 다른 나라 인삼의 수입 현황을 분석하였다. 한국산 고려인삼이 다른 나라 삼에 비해 비싸게 팔리는 것으로 파악하였다. 그리고 홍콩 인삼 수입수요 분석에서는 한국산 고려인삼의 수입물량과 수입가격 변수가 홍콩 국제 인삼시장에서 다른 나라 인삼수입에 영향을 미치는 것으로 분석되어 졌다. 이는 한국산 고려인삼이 홍콩 국제 인삼시장에서 중요한 역할을 한다고 볼 수 있다. 그러나 이러한 중요한 역할 에 비해 홍콩으로 한국산 고려인삼 수출 물량의 감소는 안타까운 일이다. 홍콩 국제 인삼시장으로 한국산 고려인삼의 수출 확대에 다시 한번 우리 모두 지혜를 모아야 할 때이다. 분석 결과처럼 한국산 고려인삼의 수출가격이 중요한 변수이므로 다양한 가격 전략에 따른 수출 마케팅 전략이 수립 되어야 한다. 더 나아가 적극적인 수출 마케팅 전략으로 고려인삼의 우수성을 꾸준히 홍보하며 객관적인 효능 연구 자료도 발표하여야 한다. 인삼 한 뿌리 생산하지 않는 홍콩이 국제 인삼시장의 물류 중심지이고 인삼 한 뿌리 생산하지 않은 스위스 제약회사 파마톤(지금은 독일 베링게 인겔하임) 의 연간 인삼제품 세계 수출액이 적어도 1억불 이상으로 고려인삼 종주국인 우리나라 인삼 총 수출액보다 많음을 다시 한번 생각해야겠다. 그리고 향후 WTO/DDA 협상이나 FTA 협상에 따른 험난한 파고에 우리 민족의 유산인 고려인삼을 어떻게 지켜 나갈 것인가를 우리 인삼인들이 모두 함께 고민해야할 문제이다.

This study investigates the impact of livestock diseases, including FMD(foot-and-mouth disease) and MCD(mad-cow disease), on pork demand in Korea. TV news stories about the livestock diseases were considered as negative advertising, and therefore the carry-over effect of negative advertising was combined with the pork demand model in conjunction with an exponential distributed lag function. The asymmetry hypothesis was imposed, however it was accepted that demand response does not show different sensitivities to increases and decreases in the livestock disease news. FMD news had a negative effect on pork demand, whereas MCD news had a positive effect, yet FMD news had a greater effect on pork demand than MCD news. The pork demand elasticity estimates for FMD and MCD news were -0.0071 and 0.0028, respectively. The cross-elasticity of the imported beef price to pork demand was highly inelastic, but it was elastic during the beef import embargo.
