Complex Network Game Study On Arctic Sustainable Fishery Trade Cooperation Under COVID-19

Marine fishery is an important source of human natural food and an important part of Marine economy.As the global climate warms,the sea ice in the Arctic begins to melt,making high-frequency navigation of the Arctic shipping routes possible.However,navigation will bring the risk of pollution to the sea area and aggravate the unreasonable commercial exploitation of fishery resources by various countries,thus threatening the sustainable development of fishery in the Arctic region.Since 2020,the global outbreak of COVID-19 and the emergence of many cases of viruses carried by cold chain logistics have aroused people’s concerns about the health and security of fishery trade.In order to prevent the epidemic,some countries have taken trade restrictions on the fishery,which has had a certain impact on the Arctic sustainable fishery trade cooperation.Arctic sustainable fisheries trade cooperation depends on the formation of mutual collaboration,in the context of the ongoing COVID-19,how to balance the sustainable development of fishery and human health prevention in the participating countries of the Arctic sustainable fishery trade cooperation has become an urgent issue facing the relevant industries and academia of the government departments of the countries along the routes.Based on complex network and game theory,this paper takes the sustainable fishery trade of the Arctic sustainable fishery trade cooperation countries as the research object,explores the situation of relevant countries’ Arctic sustainable fishery trade cooperation under the COVID-19.The current status and model are studied from two aspects: centrality analysis and simulation analysis.In terms of current status,the trade status,cooperation status and trade cooperation status of relevant countries are analyzed.The fishery trade data of relevant countries are used to calculate the centrality and overall trade density of fishery trade from2016 to 2020.In the aspect of model research,the simulation and parameter definition of the four factors are carried out,and the game model is built for simulation experiment.This paper draws the following conclusions: First,the cooperation mechanism of the countries that respond to the Arctic sustainable fishery trade cooperation is decentralized,and the current international fishery management rules are largely restricted by specific regions and specific fish populations.Second,the COVID-19 has a certain impact on the fishery trade cooperation network.Compared with the network topology of 2016-2019,the fishery trade network topology in 2020 has a slightly sparse trend,and the number of prominent node countries has decreased significantly.Third,the sustainable fishery trade cooperation in the responding countries of Arctic sustainable fishery trade cooperation is significantly affected by cooperation costs,incentive policies,game modes and the COVID-19.Finally,based on the quantitative and qualitative analysis of the full text,specific countermeasures and suggestions are put forward from the perspective of sustainable development and risk prevention.First,international and domestic cooperation mechanisms for sustainable fisheries should be established,such as the extensive formulation of Arctic fishery multilateral cooperation agreements and the strengthening of domestic policy preferences.Second,funds and technology guarantee mechanisms for sustainable development can be established,such as increasing investment in Marine protection funds and strengthening innovation in Marine science and technology.Third,the Marine ecological environment protection system can be improved.For example,the concept of win-win cooperation should be adhered to and carbon-sink fisheries should be vigorously developed.Fourth,we should build a regular epidemic prevention and control mechanism,such as strengthening epidemic information monitoring and building a multi-level participation network of Marine social organizations.
