This paper proposes a green closed-loop supply chain network (GCSN) for optimizing closed-loop supply chains. The GCSN focuses on the application of the recycling express box in logistics circulation, accelerates the standardization of logistics operations and the use of express packaging in e-commerce companies, and promotes the reduction and greening of recycling express box in the e-commerce industry. The GCSN is represented as a mathematical formulation and implemented using LINGO. Greening, environmental protection, and wisdom are the general trends for promoting the growth of the e-commerce industry. Meanwhile, the price of raw materials has increased owing to a shortage of resources, which emphasizes the need for e-commerce enterprises to develop green packaging. Therefore, this study considers the shared circular packaging launched by e-commerce enterprises as the research object, and integrates the problem of facility positioning and path planning in the logistics system. The conclusion summarizes the significance of this study.

The purpose of the study is to propose a policy implication of urban logistics in the Incheon metropolitan city. To attain the aim, it reviews new characteristics that Logistics Policy Fundamental Law(LPFL) published by government 2009 suggests and studies the previous papers like Logistic Fundamental Plan(LFP) of other metropolitan cities. After that it proposes a policy implication through benchmarking of urban logistics plan at Tokyo city not only located at a capital area at Japan but also including port and airport. The results are as follows. Firstly, field survey studies of the "LFP" every five years will need to keep pace with "Urban Fundamental Plan"(UFP) having designed to all cities legally every ten years. Secondly, Incheon will be required to create value-added logistics, making best use of third-party logistic companies to small-medium sized businesses along with the age of green. Thirdly, LFP needs to be performed through a mutual cooperation and adjustment among Incheon, Gyeonggi-do and Seoul and in this regions eco-friendly companies performing related logistic activities have to be followed executive and financial supports. Lastly, it will be obliged to develop a evaluation management index to understand the advancement level through a feedback system.

The expense Our country's land logistics system is becoming backlog day by day. The greenhouse gas which it discharges specially from the vehicle causes a ecocide and traffic expense to make. The traffic energy curtailment which the government enforces during that time and environment-friendly green goods policy lost the effect. Therefore, This research propose the car-ferri network which is the most effective logistics system substitutes the land logistics system. This research will contribute improving the north and south logistics network of Pusan and Seoul region and will be able to reduce a various goods expense.

Climate changes and environmental pollution problems are continuing every year. In Korea, the carbon dioxide(CO2) emissions by the transport sector reached around 20% of pollution. Many countries are enforcing the pollution-control policy. Korean government has introduced the modal shift grants as well as in other countries. In case of nation's transportation plan, the policy basis of green distribution is emphasized. However, the shipper and logistics company have low interests in the modal shift as the massive transportation system. The purpose of this paper is that I studied the policy alternatives for the modal shift of foreign railways., And also I studied the difficult problems at altering the railway freight from domestic road freight and I suggested the alternatives of modal shift to solve those problems.

Reliance on road transport in domestic logistics can lead to intensified congestion and greenhouse gas emissions due to the rise in oil prices, any increase in logistics costs can have a high social cost. The government policy on Low Carbon Green Growth is seeking to take advantage of the railway system. However, existing railway transport logistics systems, for reasons such as low speed, low track capacity constraints, and the impossibility of implementing a Door to Door system, make it difficult to activate a railway logistics program. As a result of this study, a national R&D project to develop a High-Speed Passenger/Baggage Mixed Train(Hy-SoBex) utilizing the rail capacity constraints to overcome the difficulties of linking an air cargo and freight railway logistics system, we propose a variety of service models and select the optimal service model.

In 1997, 180 countries signed the Kyoto Protocol in Kyoto, Japan. The Kyoto Protocol came into force in February 2005. The agreement calls for industrialized nations to cut greenhouse gas emissions by 5 percent from 1990 levels by 2008 to 2012. One of those polices is a modal shift that change from road freight to sea, inland waterway and railroad transportation that is eco-friendly. The increase of road freight brings road congestion, accidents, logistic costs, air pollution and greenhouse gases. Railroads are superior than the other modes of transportation in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. Korean railroads were used by passengers and freight transport popularly until the middle of 20th century, however, by the sudden change of logistics environments, a shaving time efficiency being most important, railroad logistic lost its competitive power against the transportation by truck. From the research which sees consequently investigated a various policy, a system and a law about Chinese logistics industry and present condition of the Chinese goods enterprise and instance analysis of the large Chinese corporation that branch out to undeveloped markets led and a Chinese logistics industry and problem point escape hereafter the heightening of competitiveness plan which is rational under prsenting boil.
