Today, the world is considered to indispensable basic data in specific gravity of international trade is increasing in economic activity of every country with globalization, and trade connection index number analyzes an economy or part of trade that contribute to economic growth of a country along with other foreign trade statistics and evaluates along with this. Also, it is becoming one of big subject for economic policy person in charge and related economists I do how measure movement of amount, price and amount of materials in trade. But, about till now interest lack about trade index and trade index creation theoretical, it is actuality that export, import connection index number or similar research is not attained much into domestic and overseas from study tribe which is gone ahead. Moreover, study that try to judge and forecast stream of market applying trade connection index number is hard to find on study until now. And, in this research, there is the objective to figure out stream of Korean market change through trade business index creation that base on Korea Customs Administration export and the importation data and this is differences with several study, and at the same time, it is value of this study.

This paper provides empirical evidences from the Baltic States on the relationship between technology and trades. In this study, regression and correlation analysis were employed an attempt to reveal the relationship between technology index and net-export coefficient, as well as the relationship between technology index and import coefficient. In this research, technology level was measured by technology index, while trades included of domestic and foreign trades; export and import. The data used for this study were collected from world input-output databases of Estonia, Latvia and Lithuania for the period 2000, 2005, 2010, and 2014. The findings remarked that the relationship between technology and domestic trade was positive and statistically significant. The result of the study implies that the higher was the technology index leads to the higher domestic transaction. Furthermore, relationship between technology and net-export was unpredictable. In year 2000, data from Estonia and Latvia showed that the relationship between variables was negative and in other years of the study, the relationship was positive. However, the relationship between variables was not statistically significant. Lastly, the relationship between technology and import was negative and statistically significant. It implies that the higher was technology index, will have a consequence the smaller was import.

Purpose - Our previous study (Chang & Lee, 2023) presented observations on the recent changes in the year-on-year (YoY) Consumer Price Index (CPI) of the Republic of Korea (ROK) after the COVID-19 pandemic. The purpose of this article is to present an integrated analysis and interpretation of the recent changes in CPI and the Aggregate Import Price Index (IPI) by incorporating recent data, specifically data from September 2022 to December 2022. Design/methodology/approach - This study collected CPI (YoY) data in the ROK from January 2019 to December 2022 using e-National Indicator System provided by the ROK. Statistical analysis was employed to analyze the data. Findings - First, we confirm the extended results of the existing study by Chang and Lee (2023). Second, we demonstrate that the Aggregate IPI in ROK increased significantly in 2022 compared to 2021. We then provide an integrated interpretation on the significant increase in CPI and aggregate IPI in ROK, which complements Chang and Lee (2023) that limits their discussion to YoY CPI. Moreover, we show that the IPI of the semiconductor in ROK decreased significantly in 2022 compared to 2021. Research implications or Originality - Our results provide important insights into the recent changes in the CPI in the ROK. The results suggest that these changes can be partially attributed to various factors, such as the global supply chain disruptions resulting from the spread of the COVID-19 pandemic and the prolonged war between Russia and Ukraine, the side effect of quantitative easing by the US Federal Reserve, heat waves and droughts caused by climate change in ROK, a surge in demand following a gradual daily recovery, US-China trade conflict, etc. Our study shows statistically comprehensive results compared to the studies that limit their discussion to YoY average growth rate.

This paper tries to estimate Korea's import demand function for fisheries using cointegration analysis. The estimation function consists of one dependent variable-import quantity of fisheries(FTIW) and two independent variables-relative price(RP) between importable and domestic products and real income(GDP). As it has been empirically found out that almost all of time series of macro-variables such as GDP, price index are nonstationary, existing studies which ignore this fact need to be reexamined. Conventional econometric method can not analyze nonstationary time series in level. To perform the analysis, time series should be differenciated until stationarity is guaranteed. Unfortunately, the difference method removes the long run element of data, and so leads to difficulties of interpretation. But according to new developed econometric theory, cointegration approach could solve these problems. Therefore this paper proceeds the estimation on the basis of cointegration analysis, because the quartly variables from 1988 to 1997 used in the model is found out to be nonstationary. The estimation results show that all of the variables are statistically significant. Therefore Korea's import demand for fisheries has been strongly affected by the variation of real income and the relative price.

This study analysis the market status and competitive structure of Korean fishery in Japan import market, and derive policy implications for seeking main causes. Specifically', trade state between Korea and Japan is discovered and theoretical model is also used to analysis competitiveness between two countries. And then real measuring methods of competitive index is Introduced, the status of Korean fishery products in Japan import market is analysed totally through the study of comparative predominance and export competition. The analysis is based on the statistical methods such as RCA, RMI, and CMS. In summary, first, Korean fishery products have the comparative predominance in Japan, China and Thailand, but they have the comparative inferiority in USA, considering research results. Second, competitiveness of fishery products between Korea and in Japan import market extreme, relatively, competitiveness of Korean fishery products for Thailand's fishery products is lowest. Third, Korean fishery products maintain unconstant pattern, but competitive inputs result in increasing export to Japan generally.

This study aims to investigate the relationship between cargo volume and logistics performance index published by World Bank which indicate countries' logistics performance. In this study, the results were derived through panel regression analysis consisting of variables such as gross domestic product, geographical distance, population, and LPI using container export/import volume and bulk export/import volume as dependent variables. As a result of the empirical analysis, it was found that Korea's container volume was affected by the overall level of logistics, in particular, was deeply related to the logistics infrastructure, while bulk volume was not related to the logistics level or was less influential.

Purpose - The logistics industry is often featured by its location relevance and industrial concentration. Industrial concentration is conducive to the effective transmission of information by reducing transaction costs and improving transaction efficiency, thus promoting the development of trade. The main purpose of this paper is to measure the spatial total factor productivity and location quotient of the logistics industry in Korea, and to study the impact of the logistics industry efficiency and agglomeration effect on import and export trade in Korea. Design/methodology - First, used the spatial stochastic frontier method to measure the spatial total factor productivity of the logistics industry in Korea, this serves as the efficiency index of the logistics industry in various regions of Korea. Second, calculated the location quotient (LQ) of the logistics industry to measure the industry's concentration degree. Third, employed a spatial econometric model to analyze the impacts of factors such as the efficiency and concentration levels of the logistics industry on import and export trade in Korea. Findings - This study's main findings can be summarized as follows: this study found that the overall efficiency of the logistics industry in Korea needs to be improved, even though it showed an upward trend in all regions of the country; Moreover, the agglomeration level of Korea's logistics industry needs to be improved; Finally, the positive spatial correlation and industrial agglomeration effect of Korea's logistics industry had a positive impact on the country's import and export trade. Originality/value - This study is innovative in terms of research perspective and methods. Most of the previous studies have measured the development level of the logistics industry using the logistics performance index (LPI), Fewer studies have assessed through the spatial total factor productivity and location quotient of the logistics industry in Korea to measure the efficiency index of the logistics industry in various regions of Korea and concentration degree, as well as there was almost no study on the impact of logistics industry efficiency and agglomeration effect on import and export trade in Korea. This study addresses this limitation by analyzing the impacts of the efficiency and agglomeration effect of the logistics industry on import and export trade in Korea.

This study is aimed to investigate the structure of world pollack markets and the position/competitiveness or Korea for WTO/NAMA Negotiation. First or all, it is clearly pointed out that many limitations and problems are inherent in FAO statistics that is widely utilized to investigate the structure of international seafood markets. Especially, it is impossible to find not only the data for Russia that is the top production and export country of pollack, but also the data for importing/exporting countries for pollack. In order to make up for these problems, the data for export and import of major countries are collected and analyzed. The results of analysis show the followings. First, it is clearly investigated that classification of fish products are different for countries. Second, it is understood the structure of international pollack market in actuality. The pollack market is segmented by frozen, fresh, dried, fillet, roe, surimi, etc. In addition, the pollack market has grown as much as 600,000 tons in amount and $1.2billion in value. Third, competitiveness of Korea in international pollack markets is measured quantitatively. It shows that Korea has low RAC index and TSI index, but high RMI index. Thus, it is identified that Korea becomes the largest pollack importing country. Fourth, the partial equilibrium analysis on pollack import market of Korea indicates that the frozen pollack has both price elasticity and substitution elasticity, while the fresh pollack has income elasticity.

최근 관세청이 15개 수입소비재 품목 가격을 분석한 결과, 수입가격 대비 국내 판매가격은 2.1-4.8배 수준인 것으로 나타났다. 이는 아직도 독점 수입업체들이 폭리를 취하고 있다는 것을 보여주는 결과이다. 독점 수입업체가 아닌 제3자가 제품을 수입할 수 있는 병행수입은 1995년 이미 허용되었으나, 위조품 논란, A/S문제 등 때문에 실제 소비자 후생으로 이어지지 못했다. 정부가 최근 병행수입 활성화 정책을 펴면서 지난해 규모가 3조원으로 늘었으나, 아직 전체 소비재 수입의 5%에 불과하다. 관세청이 정식통관 제품이라는 것을 보증해주는 통관인증제 대상 업체와 품목 확대로 통관 인증업체가 344개로 늘어난 것은 매우 다행스런 결과이다. 이에 본 연구는 현재 국내 병행수입 시장의 실태와 문제점을 분석하고, 정부의 "독과점적 소비재 수입 개선방안"의 검토를 통해 향후 병행수입 제도가 국내 경제 활성화와 수입시장의 경쟁 제고를 위해 나아가야 할 방향을 제시하고자 한다.
