Green Efficiency Evaluation Of Coastal Ports In China Based On Structural Adjustment Of Collecting And Transportation

In 2017,the Ministry of Transport,the National Railway Bureau and the China Railway Corporation jointly issued the "13th Five-Year Plan" for the construction of a port transportation system to carry out a multi-modal transport demonstration project.The Railway Corporation issued the "2018-2020 Incremental Action Plan for Cargo Transport",which requires about 80%of the highway iron ore dredging volume in the main ports of the Bohai Sea to be converted to railways,focusing on increasing the proportion of railway transportation,promoting combined sea and rail transport,and water transit transportation.Wait.The implementation of the policies related to the adjustment of the structure of mass transit will directly change the cargo transportation structure of the port,reduce the amount of road transportation to a certain extent,actively build railway transportation lines,and adjust the port management plan accordingly.As an important component of the transport system,port transport has always been committed to further standardization of ship types,green ecology of ports,promotion of clean energy,and intelligent management in terms of technological innovation,adjustment of transport structure,and related policies.We will promote the green and sustainable development of ports.In June 2018,the "Three-Year Action Plan to Win the Battle of the Blue Sky" was formally released.Together with the "Sulphur Restriction Order"issued by the International Maritime Organization,the degree of greening of the port will be an important consideration for the development of the port.Therefore,it is especially necessary to evaluate the efficiency of port green development.This paper focuses on the impact of the adjustment of the structure of mass and transportation on the overall green efficiency of coastal ports in China and the definition of the green development stage.Firstly,this paper introduces the background and significance of the research,and reviews the literature related to the same type of research at home and abroad.After that,it introduces the main theoretical meanings involved in the article and lays a theoretical foundation for better understanding the main meaning of the article.Secondly,this paper analyzes the general situation of green port construction and its existing problems in the process of construction,expounds the development of green port in China and abroad,and points out the main reference directions in the evaluation of green efficiency.Then the green efficiency of major coastal ports in China is evaluated and clustered.In view of the current green development of domestic ports and the main influencing factors,an evaluation index system was established.On the basis of this,the fuzzy C-means clustering model analysis and the fuzzy grey cloud clustering model analysis were conducted,and different years were selected for comparison.The green efficiency stage of 16 ports along the coast of China is obtained.
