The 21st Century Maritime Silk Road (MSR) is an important part of Belt and Road Initiative(BRI). As an economic and trade corridor for dozens of countries in Asia, Europe and Africa, and the port as an important link node, the efficiency of port operation directly affects the implementation of BRI's strategy. On the basis of combining BRI and related evaluation methods of port efficiency, this paper uses DEA-BCC model to select port production berth number and production berth length as input index container throughput and cargo throughput as output index to analyze the port efficiency of 14 ports in China. The results show that: (1) The overall efficiency level of the ports along the MSR is relatively low. Most of the ports have not reached the DEA efficiency and there are different degrees of problems in scale investment and technological improvement. However, this situation is accompanied by the implementation of China's maritime cooperation strategy and becoming better year by year. (2) The low operating efficiency of ports along China's MSR is mainly due to the lack of coordination between scale efficiency and technical efficiency, which is caused by insufficient scale investment in the port itself, weak economic linkage between the hinterland and the port, (3) Whether a port has a strong comprehensive strength does not entirely depend on the cargo throughput or scale but also includes the port's operating efficiency.

Recently, air pollution from the marine ports has become a serious issue all over the world. Because marine trade accounts for 99.7% of Korea's trade, efforts are required to recognize the level of port pollution and establish environmental policies. This study estimates air pollution emitted during the berthing process in the Gwangyang and Ulsan ports. Data on ship activity and characteristics are collected and reasonable methodologies and factors from EEA and EPA are adopted. The results show that 253.09 tons of CO, 1986.61 tons of NOx, 684.01 tons of SOx, 47.88 tons of $PM_{10}$, and 44.69 tons of $PM_{2.5}$ are emitted at the Gwangyang port. Further, the Ulsan port emitted 212.28 tons of CO, 1712.54 tons of NOx, 573.72 tons of SOx, 40.16 tons of $PM_{10}$, and 37.48 tons of $PM_{2.5}$. A stage-by-stage plan for installing AMP infrastructure is suggested as part of a green port policy. This research provides the current pollution status and contributes guidelines for the direction of future policy.

This study aims to analyze the effect of reducing air pollutant emissions of the ship fuel oil sulfur content regulation policy, which has been gradually introduced for three years. In addition, the emission reduction effect of VSR and AMP was also analyzed. The analysis was conducted on NOx, CO, VOC, SOx, TSP, PM10, and PM2.5, which are provided by EEA, and the spatial scope of the analysis was conducted on Incheon Port, which is located in the metropolitan area of Korea and has a large ripple effect on air pollution. Three scenarios were constructed for analysis. Scenario 1: If there is no policy, Scenario 2: If only fuel oil sulfur content regulation was implemented, Scenario 3: The analysis was conducted by reflecting fuel oil sulfur content regulation, VSR, and AMP. As a result of the analysis, in the case of scenario 1, 4,801 tons, 4,932 tons, and 5,144 tons of air pollutants were emitted during the three-year period. In Scenario 2, 4,219 tons, 4,152 tons, and 3,989 tons were discharged, and in Scenario 3, 4,198 tons, 4,138 tons, and 3,973 tons were discharged. The findings of this study are anticipated to be applied as fundamental research in port air environment management and Incheon Metropolitan City air management.

Logistics needs in Asia are surprisingly increasing due to rapid growth of China in Northeast Asia We are endeavoring to make an economic block in opposition to NAFTA and EU by economic revival, political stability, and easing of exclusive parts between countries as increasing of traffic infra such as asian highway, transcontinental railway in the region of Northeast Asia and as considering diversification of transportation mode. Now, Busan is not a final terminal of this business, and it is not a concreted level in considering an undersea tunnel between Korea and Japan as effort to extend to Japan. Therefore, this study performed an effect analysis which be affected to Northeast Asia and Korea in future by analysis and comparison of a cost and time required of marine transportation and railway before and after construction through course analysis and summary of discussed content until now for undersea tunnel between Korea and Japan. This result expects as a accelerative play for study cf undersea tunnel between Korea and Japan in future. In this result, we estimate that it is an effective things in a cost and time required if undersea tunnel between Korea and Japan is constructed, and we simply searched for theirs effects in the aspects of Northeast Asia, national balanced development, regional economic in Busan, and marine logistics.

Cruise industry is a continually growing high value industry despite of economic recession. As Chinese cruise tourists increase, the cruise industry in Northeast Asia has been attracting attention. Korean ports have constructed cruise terminals with vision of becoming a cruise home port. Asian leading cruise country, Singapore has cruise industry strategy linked with Singaporean tourism strategy. Based on the Singaporean cruise industry, several strategies for Korean cruise industry development are suggested. Analyzing the economic effect of cruise home port and call-port and Korean cruise industry environment shows that Busan port is fit for home port, Incheon port is fit for sub home port, and Jeju port is fit for call-port. Korean cruise ports are playing a role in call-port in Northeast Asia cruise market, an introduction of Korean cruise company and home port by the company are needed to develop the Korean cruise industry.

If a system has a large boundary and complexity, forecast's accuracy will be very low when consider the system's substance as black box. Thus, it is necessary that analysis by structure model. To examine competition in Northeast Asia Ports, it has assumed that the form of structure model, For which the System Dynamics method is adapted in this paper. Northeast Asia Ports Model includes five ports - Pusan, Kobe, Yokohama, Kaoshiung, Keelung, - which are adjacent to each other by geographically and has a competition relation. The Northeast Asia Ports Model has several sub-systems which consists of each unit port models. And, each unit port model found by quantitive, qualititive factors and their feedback loops. All effects which components of one port have influence to components of the rest ports must be surveyed in order to construct Northeast Asia Ports Model, but it may be impossible currently. In this paper Northeast Asia Ports Model was simplified by HFP-Hierarchical Fuzzy Process Method-adapted to integration of level variables of unit port model. Container cargo volumes in Northeast Ports Model is distributed by results of HFP method. And distributed container cargo volumes effected to unit port model. Developed model can estimate change of container cargo volumes in competitive relation by alternation of simple parameter, and reflects dynamics characteristics which are included in model.

Coastal ports play an essential role in developing a country and a city. Port efficiency is an important factor affecting port trade, and the importance of port efficiency for port performance has been recognized in previous literature. DEA (Data Envelopment Analysis) and SFA (Stochastic Frontier Analysis) are widely used in this field of research. However, these two methods are limited in selecting input and output variables. In addition, the literature studies on Chinese coastal ports mainly focus on the study of port clusters in local areas, which lacks a holistic approach and generally lacks up-to-date data. Therefore, to fill the gap in this area of research, this paper introduces a model combining principal component analysis and data envelopment analysis to analyze the operational efficiency of the top 17 coastal ports in China in terms of throughput based on the most recent data available in 2021. This paper identifies container throughput as the output variable, and 13 second indicators are selected as input variables from four primary indicators: land, capital, labor, and infrastructure. Four principal components were selected from 13 second indicators using PCA.After that, DEA (BBC) and DEA (CCR) were used to analyze the 17 ports, among which five were Shanghai, Ningbo-Zhoushan, Guangzhou, Xiamen, and Dongguan, respectively, DEA efficient, and the remaining 12 ports were non-DEA efficient. Finally, improvement directions for each port are derived, and brief suggestions are made. This paper provides some reference value for developing and constructing coastal ports in China.

As the 'Eco-friendly conversion project for Port's CHE(Cargo handling Equipment) ' which has started in 2014 ends in 2024, in addition to the existing 'Low pollution' paradigm to respond to fine dust problems, a full-fledged 'Zero-emission' conversion is to be required to implement 2050 carbon neutrality at the port level. Accordingly, this study calculated the future replacement demand for container handling equipments at the four major domestic ports(Busan, Incheon, Yeosu Gwangyang, and Ulsan), and assumed a scenario where every CHE supposed to eb replaced is electrified inturn every year. And then the resulting future emission reduction effect accordingly was calculated and analyzed. In particular, compared and analyzed the emission outlook applying the life-cycle concept(LCA), which is being adopted as a new emission calculation standard in most industrial fields, and the existing emission calculation concept that only considers direct emissions within the port, to provide more effective implications for the promotion of follow-up conversion projects. According to the analysis results, if the CHE is replaced according to the proposed schedule, it is expected that the existing emissions can be reduced by 79% compared to BAU in 2025 and 97.4% in 2030. However, if the LCA is applied, it is expected to be reduced by only 27.6% by 2030. This suggests that port's CHE must be converted to zero emissions and at the same time establish an Ports' self-sufficient energy grid based on renewable energy.

Increasing of the multinational corporation brought into the international multimodal Increasing of the multinational corporation brought into the international multimodal transport on the logistics environment. In case of Europe which have a great infrastructure, they are tried to develope a second of the silk road constantly. This paper emphasized the importance of international multimodal transport and proposed the model for northeast multimodal transport. For this research, we analyzed the multimodal transport system in Europe and north corridor of TAR. We are expecting economic effect of the route is including republic of korea and developed a model for connecting with sea, air and road. Actually, this research can not be enough data of numerical value for proving this effectiveness. but we developed and proposed a specific route of multimodal transport that was never suggested. Consequently, we established basic ground for comparing each transport route in the future research.
