On The Interaction Between Finfish Mariculture Agglomeration And The Resource-Environment

Due to the natural resource endowment,many farming areas in China formed finfish mariculture cluster,such as Xingcheng,Ningde and Zhuhai city.Mariculture cluster plays an positive role in regional economy,it can help to reduce the production cost and transaction cost,accelerate the adoption of new technologies and practices,form the regional brand,thus the economic efficiency can be increased.however,the current size and growth rate of the cluster has raised many environmental concerns,such as resource depletion and pollution,if the environment no longer sustainable,the farming industry and regional economy will also be affected.Therefore,it is of great scientific value and realistic significance to study the interaction between finfish mariculture cluster and resource-environment to coordinate the development of mariculture cluster,the protection of environment and efficient use of the resources.This thesis studies the agglomeration of finfish mariculture,firstly,in order to examine the impact of resource endowment on the agglomeration of finfish mariculture,the comparative advantage and geographical agglomeration level of mariculture area were analyzed using the coefficient of resource endowment,the model of comprehensive comparative advantage,location quotient and concentration ratio.Based on the previous research,this paper summarized the pressure on natural resources brought by finfish mariculture,calculated its eutrophication cost.Despite its negative environmental impact,finfish mariculture can provide positive provisioning services and cultural services value.Thus,this paper take Chinese sea perch(Lateolabrax maculatus)cluster(located inFuding city,Fujian province)as an example to evaluate the net resource value.Based on the above analysis,serveral suggestions were made to promote the development of finfish mariculture cluster while minimize its negative impact on resources and environment.The research results are as follows: firstly,Guangdong,Hainan and Fujian provinces had the resources endowment advantage in finfish mariculture,which is thebasis of scale comparative advantage,thus the above mentioned area had the comprehensive advantage in finfish mariculture.The agglomeration level of these three area proved the positive influence of resource endowment on the agglomeration of finfish mariculture.Secondly,under the same circumstances,the impact of resource endowment on finfish mariculture agglomeration is the biggest,followed by scale advantage and efficience advantage.Thirdly,Fujian,Guangdong and Hainan also had the highest environmental pollution cost.Although the production volume of farmed marine finfish in Fujian was much lower than that of Guangdong province,the pollution cost in Fujian was higher than counterpart.This is because cage farming was widely adopted there.Lastly,the net resource value provided by Chinese sea perch cage farming cluster was positive,however,the ecological value was negative,indicates that the cluster lacks of environmental sustainability.In order to improve the interaction between the agglomeration of finfish mariculture and the resource-environment,the suggestions are as follows: First and foremost,areas with scale comparative advantage in finfish mariculture should take measures to improve eco-efficiency.Then,areas with high level of agglomeration should enhance regional ecological brand.As for the local government,they should implement suitable environmental-economic policy according to the main production mode of finfish mariculture clusters.In order to transform and upgrading the agglomeration,measure should be adopted to increase the net resource value.
