산업통상자원부에서 제공하는 KOTRA 무역 데이터는 해당 품목과 해당 국가에 대하여 GDP, 관세율, 비즈니스 점수, 과/차년도 수출금액 등을 제공한다. 그러나 무역 수출품목은 수 없이 많을 뿐더러 그에 따른 대량의 데이터를 매년 인간의 분석을 통해 유의미한 결과를 이끌어내는 것은 상당히 큰 시간과 비용을 요구한다. 따라서 이번 연구에선 대량의 데이터를 학습하여 단기간에 저비용으로 결과를 예측할 수 있는 심층신경망 모델을 구현해 보았다.

지난해 인쇄업계의 인쇄물수출은 전년에 비해 20% 가까운 증가세를 보인 가운데 2억5천만 달러를 기록했다. 인쇄물수입은 2.6% 증가에 그쳤지만 금액으로 3억6352만 달러를 기록해 인쇄물의 무역수지는 1억 달러가 넘는 적자를 기록한 것으로 나타났다. 최근 수년간 인쇄물의 수출액이 2억 달러 수준에서 제자리걸음에 가까운 움직임을 보이고 있는 가운데 인쇄물의 무역 수지는 여전히 적자를 벗어나지 못하고 있는 현상이 고착화되지 않을까 하는 우려가 일고 있다. 더욱이 지난해처럼 달러화, 유로화, 엔화 등 기축통화에 대한 원화의 가치가 떨어지면서 수출에서의 가격경쟁력이 상대적으로 높아진 것으로 평가됨에도 불구하고 기대만큼의 높은 증가세를 보이지 못한 것은 아쉬움을 남기고 있다. 또한 대안 마련의 필요성도 대두되고 있다. 해외 마케팅 전문인력의 부족, 미흡한 정부 차원의 수출지원, 중국 등 후발국가에 대한 가격 경쟁 열세 등 우리 인쇄산업의 수출 확대에 가로 놓인 어려움이 적지 않지만 이런 어려움 가운데서도 인쇄물 수출에 아낌없는 노력을 기울여 나름대로의 성과를 거두고 있는 업체들도 있다. 긴 호흡으로 보아야 한다는 인쇄물 수출 분야에 단기간의 성과를 기대하며 도전하는 것은 금물이라는 말이 있다. 내수시장의 고질적인 어려움을 감안, 중장기적으로 수출시장의 개척에 대해 진지하게 모색하는 것은 이제 인쇄업계에 몸담고 있는 이라면 누구라도 공감할 과제의 하나로 다가오고 있다. 인쇄물 수출분야에서 성과를 거두고 있는 업체들을 만나 본다.

Export credit insurance is a policy tool for export growth. In the era of free trade under the governance of WTO, export credit insurance is still allowed as one of the few instruments to increase exports. This paper, using data on short-term export insurance contracts issued to foreign subsidiaries of Korean companies, calculates the expected loss per exposure by combining the effect of risk factors (credit rate of foreign importers, size of mother company, and payment period) on loss frequency and loss severity in different levels. We, applying generalized linear models (GLM), first fit loss frequency and loss severity to negative binomial and lognormal distribution, respectively, and then estimate the loss frequency rate per contract and the ratio of loss severity to coverage amount. Finally, we calculate the expected loss per exposure for each level of risk factors by combining these two rates. Based on the result of statistical analysis, we present the implication for the current premium rate of export insurance.

Korea Trade-Investment Promotion Agency (KOTRA) annually publishes the trade data in South Korea under the guidance of the Ministry of Trade, Industry and Energy in South Korea. The trade data usually contains Gross domestic product (GDP), a custom tariff, business score, and the price of export items in previous and this year, with regards to the trading items and the countries. However, it is challenging to figure out the meaningful insight so as to predict the future price on trading items every year due to the significantly large amount of data accumulated over the several years under the limited human/computing resources. Within this context, this paper proposes a multi layer perception that can predict the future price of potential trading items in the next year by training large amounts of past year's data with a low computational and human cost.

Rapidly growing cross-border e-commerce exhibits different characteristics from traditional trade. This paper empirically investigates influencing factors of CBEC trade between Korea and foreign countries including product characteristics, such as product type and unit price. We construct panel data based on Korea's e-commerce export data by country and product and analyze it by the OLS, fixed effect, and random effect estimation. Our main findings can be summarized as follows: geographical distance still remained as an obstacle to the CBEC trade, product unit price, and durable consumer goods dummy variables positively affect e-commerce export of Korea, and capital goods dummy variables negatively affect e-commerce export. This research can help us understand the characteristics of cross-border e-commerce and can be used as a basis for future research using product-specific data.

The study attempts to consider L/G(Letter of Guarantee) in a different angle, which is internationally used as a way of commercial customs and practices in a case when the consignee wants to receive the goods without the original Bill of Lading, Thus, this study focuses more on verifying the usage of L/G in Mixed Payment System and the range of guarantee responsibility by an issuing bank through case analysis. This case uses a mixed payment method of L/C(Letter of Credit) and T/T(Telegraphic Transfer) in the transaction of goods. The issuing bank of L/C issues L/G with the amount of L/C which is the same as the amount as C/I(Commercial Invoice). However the carrier deliver all goods laden under both L/C and T/T payment with the production of L/G. In this case, because the buyer is unable to pay, the seller makes a claim for damages to the carrier that the carrier delivers the goods to the buyer against L/G. Finally, the judge gives a decision that the issuing bank of L/G should pay the whole amount of the goods. In this case, the main issue of the dispute is the range of guarantee responsibility by the issuing bank of L/G. As a result of the case analysis, the study suggests two counter strategies for smooth utilization in international trade environment. First, in the case of mixed payment system, a seller should issue a commercial invoice separately based on the amount of each settlement plan in order to clarify the liability of guarantee. Second, banks should establish a new form for L/G including a sentence for verifying liabilities of the bank's side in the current form of L/G.

중국의 급속한 산업화로 대기, 수질, 폐기물 등 환경오염문제가 심화, 고착화되면서 이를 개선하기 위해 중국 정부는 환경규제를 지속적으로 강화하고 있다. 또한 외국인 투자유치로 제조업 육성에 어느 정도 성공을 거둠에 따라 외국인 투자 유치와 제조업 경영활동에 있어 환경 이슈를 매우 중요시하고 있어 신규 및 사업확장에 제동이 걸리고 있다. 중국은 신규법인수 기준으로 우리나라의 최대 해외직접투자국이며, 제조업종에 대한 투자금액이 전체 투자금액의 88.3%를 차지하고 있다. 중국에 진출한 기업들은 중소기업이 전체 진출기업의 약 90%로 중국의 환경규제 강화는 중국에 진출한 우리 중소기업들에게 직접적인 영향을 미치고 있다. 중국 정부는 분야별 환경목표를 강화하고 오염물질배출 업체를 퇴출시키는 등 강력한 조치를 전개하고 있으며, 중앙 정부의 환경목표 강화 기조와 더불어 해당 지역민의 친환경에 대한 요구가 점차 커짐에 따라, 각 지방정부는 환경 관련 지역 목표 달성을 위해 업체 관리감독을 대폭 강화하고 있는 추세이다. 이러한 중국의 환경규제 강화는 진출 기업이나 진출을 준비하는 기업들의 설비투자비나 오염배출비용 부담 증가 등 상당한 리스크로 작용하고 있으며 향후에도 중국의 환경규제 강화 기조는 지속될 것으로 전망된다. 실제 중국에 진출한 기업들은 환경규제를 직접적으로 체감하고 있다. 규제집행의 강도가 눈에 띄게 높아져 엄격한 기준을 적용받고 처벌수위 역시 높아졌으며, 과거 관시를 통해 원만한 해결이 가능했다면 이제는 환경규제에 대해 원칙적이고 보수적인 공무원의 태도로 인해 관시로도 해결이 어려운 경우가 다반사이다. 또한, 주민들도 환경규제에 대한 인식수준이 높아짐에 따라 미미한 사안에도 즉각적인 반응을 보여 민원제기 사례가 빈번히 발생하고 환경안전 기준이 점점 높아짐에 따라 이에 대응하기 위해 환경안전 설비추가, 친환경연료 사용 등 추가적인 비용이 발생하고 있다. 이에 이미 진출한 기업들은 소재지 환경규제의 강화 전망 및 이로 인한 손실정도를 사전에 파악하고 다양한 옵션에서 대응전략을 마련해야 하며, 향후 중국 진출계획을 가지고 있는 기업들은 진출에 앞서 지역별로 차별화된 시장기회와 환경규제 강도 등 현지 실사를 통한 현장중심 리스크 분석을 실시해야 한다. 또한 이미 진출한 기업 및 진출예정 기업 모두 환경규제가 강화되고 있는 중국에서 사업을 하기 위해서는 법규와 기본원칙을 반드시 준수하고 규제가 더 강화될 것 이라는 기조를 인식할 필요가 있다.

The seller and the buyer write down the agreed details in the trade contract as trade contract clauses. In the case where a letter of credit is agreed to be the payment condition, the buyer shall open a letter of credit to the seller with the shipping date specified in the trade contract through its bank. In this case, the legal relationship between the performance date of the trade contract and the shipment date of the letter of credit, the change of the performance date of the trade contract due to the change of the trade contract and the change of the shipment date specified in the letter of credit, the seller's letter of credit A problem arises in the legal interpretation of the approval period and the change request period. Therefore, this paper analyzed the precedents of the Seongnam Branch of the Suwon District Court and the Seoul High Court related to these legal issues. The performance date of a trade contract is the seller's delivery date and the buyer's payment date. In the letter of credit transaction, the date of performance of the trade contract is regarded as the date of shipment and the date of negotiation of documents specified in the letter of credit. The seller must decide whether to accept the letter of credit within 5 banking days after receiving the letter of credit from the buyer. After this period has elapsed, the seller cannot refuse the letter of credit. However, if the buyer is unable to decide whether to accept the letter of credit within 5 banking days due to reasons attributable to the buyer, the delivery date specified in the letter of credit will be extended. If the seller requests an amendment to the letter of credit, the buyer must accept it and open the letter of credit the seller desires to the seller. If the buyer refuses the seller's request to change the letter of credit, company A has the obligation to change and reopen the letter of credit as requested by company B. Expect by agreeing on the quotation As it is a fundamental breach of contract stipulated in Article 25 of the United Nations Convention on Contracts for the International Sale of Goods, company B can cancel the trade contract and claim damages from company A. Compensation for damages caused by Company A's breach of the trade contract shall be an amount equal to the loss suffered by Company B as a result of the breach, including loss of profits.

At the beginning of the COVID-19 pandemic, Korea's wine market had shrunk as other countries. However, right after the pandemic, Korea's imported wine consumption had been increased 69.6%. Because of the ban on overseas travel, wine was consumed in the domestic market. And consumption of high-end wines were increased significantly due to revenge spending and home drinking. However, from 2022 Korea's wine market has begun to shrink sharply again. Therefore this study forecasts the size of imported wine market by 2032 to provide useful information to wine related business entities. KITA(Korea International Trade Association)'s 95 time-series data per quarter from Q1 of 2001 to Q3 of 2023 was utilized in this research. The accuracy of model was tested based on value of MAPE. And ARIMA model was chosen to forecast the size of market value and Winter's multiplicative model was used for the size of market volume. The result of ARIMA model for the value (MAPE=10.56%) shows that the size of market value in 2032 will be increased up to USD $1,023,619, CAGR=6.22% which is 101% bigger than its size of 2023. On the other hand, the volume of imported wine market (MAPE=10.56%) will be increased up to 64,691,329 tons, CAGR=-0.61% which is only 15.12% bigger than its size of 2023. The result implies that the value of Korea's wine market will continue to grow despite the recent decline. And the high-end wine market will account for most of the increase.
