Investment Choice Model Of Dry Bulk Carriers And Its Empirical Study Under The Background Of The Green Supply Chain

With the growth of China's economy,investment cooperation is keeping increasing.Howevervat the same time the shortage of resources and ecological destruction have a serious impact on economic development With the implementation of "One Belt And One Road"strategy in the context of Green Supply Chain,the competition and investment of shipping industry in the international market have been promoted with the expansion of various kinds of infrastructure,ship repair and construction,port construction and channel construction,as well as the rapid growth of shipping and trade.By implementing the policy of exemption from import and value-added tax in the free trade zone,it has great attraction to ship investors and provides a rare opportunity for the capacity transfer of China's ship industry.It has become an urgent need for China to establish international capacity cooperation and Chinese standards.Since the beginning of the industrial revolution,dry bulk carriers have been the driv ing force of world industry.Although the driving factors of industrial expansion have changed and trade has fluctuated dry bulk carriers are still an important force of industrial development.In shipping management,dry bulk ships not only occupy an important leading position in profitability and labor demand,but also occupy an important position in the most important types of cargo trade in shipping.However,under the dual background of overcapacity and environmental pollution in the shipbuilding industry,the transformation and upgrading,greenlization and intelligent development have become the general trend of the current industry development.The high-tech green ship with low emission,low oil consumption,energy saving and environmental protection has become an inevitable trend in shipping industry and shipbuilding industry.Green ship has its own requirements and standards,from design,construction,operation and repair until apart.This not only faces many uncertain factors,but also has certain market risk.A blind investment will definitely cause a decline in investment benefit.Therefore,it is needed urgently to explore a scientific model of investment choice model of dry bulk ships under the premise of building Green Supply Chain(MDIGSC)facing unity in shipbuilding and shipping market environment.This will provide beneficial reference for modern ship investment decision.The selection of ship investment is studied on the basis of the economic index of investment,and focuses on the selection of investment decision scheme.Through the definition of ship investment choice,the connotation of Green Supply Chain under the background of ship investment,the status quo and problems of investment choice of dry bulk ships under the premise of building Green Supply Chain are analyzed.Based on the analysisy the research framework is costructed.Conceptual modelling is the first step to define analyze the procedure of investment and the classification of decision-making.Then,impact facors are found.The uncertainty of investment selection index of dry bulk ships is further analyzed.Combination of cloud model and prospect theory is applied to further mocelling.Thirdly,the dual group decision-making fusion mechanism for DIGSC is constructed to measure the consistency of investment selection and build the feedback control mechanism.Finally,an example and empirical study of DIGSC are presented,and the guarantee strategy of dry bulk ship investment selection is put forward.First,the characteristic and conception of green supply chain and investment choice in the context of green supply chain are defined.According to the current situation and exist problems in the context of green supply chain,construct an initial group decision making model for dry bulk carriers under green supply chain environment and build a goup decision making model combined the cloud model and prospect theory further.Measure the consistency degree and feedback mechanism of investment choice group decision,and analyze the relationships between different chapters.Secondly,theoretical research on the investment selection model of dry bulk carriers under green supply chain enviromnent.Though analyzing criteria of the ship investment choice,then analyze the investment choice process,including the decision subjects,alternatives,criteria evaluation and decision results.Define the investment deicision type including decision goal and decision state class,and analyze the influencing factors of dry bulk carriers.Thirdly,the construction of dry bulk ship investment selection model in the context of green supply chain.Through the uncertainty analysis of indicators in the context of green supply chain,the second-order normal cloud model is used to cloud the indicators to achieve quantitative conversion of indicators.Then introduce the prospect theory with dynamic reference point and risk attitude,and combine the cloud model to construct a theoretical model for decision-making of dry bulk ship investment choice.Fourthly,dual fusion mechanism of group decision making for dry bulk carriers under the green supply chain.Based on the uncertainty of linguistic variables and numerical scores,evaluate the attributes of dry bulk carriers,and one-to-one mapping of linguistic level and membership.Measure the consistency degree of dry bulk carriers by aggregating the experts'evaluation of group decision,then put forward the feedback and adjustment mechanism,in order to achieve a higher satisfaction level of dry bulk carrier investment choice.Fifthly,empirical study on ship investment choice under green supply chain environment The linguistic variable evaluation and dual fusion mechanism of group decision under green supply chain.Comparing the two investment choice efficiency of dry bulk carriers,providing the investment choice option.Meanwhile,utilizing a sensitive analysis to analyze the key factor under green supply chain environment.Finally,put forward the protection policy of investment choice.Propose the protection of investment choice process of dry bulk carriers,including human capital guarantee,internal and external information guarantee and scientificalness guarantee of investment decision.Thus,raising a comprehensive guarantees for dry bulk carriers under green supply chain environment.
