Research On Allocation And Trade Mechanism Of Ocean Emission Permit Based On Complex Network

The dissertation adopts normative research and empirical research on allocation and trading of ocean emission permits. Firstly, the dissertation constructs pollution network, which can provide platform for emission trading in the future; Secondly, a hierarchical allocation model about initial emission permits is proposed; Thirdly, the dissertation researches how to trade emission permits based on complex relationship network; finally, the dissertation researches on technology incentives of emission trading policy.According to relevant researches, some outcomes and conclusions are made.First, construct allocation model of initial permits among function zones. The model integrates welfare optimization principle with economical efficiency principle. It also contains interest compensation mechanism based on fairness principle. Through analyzing the model, the dissertation gets some conclusions. To begin with, the residents will make emission permit abatement decision based on the principle that margin pollution damage equals to margin consumption utility and margin income utility. Residents will abate the most if margin pollution damage is larger than margin consumption utility and margin income utility. Residents will abate zero if the opposite is true. Additionally, quantity of distributable initial permits is positive relation with price of emission abatement and with residents consumption utility increase under per increase of distributable initial permit. There exists a threshold that if the price of emission abatement is larger than it, residents will abate zero initial permits. Moreover, an adjustment coefficient is given. Objective of fair allocation is to achieve minimum total differences among fair allocation quantity adjusted by the adjustment coefficient. Finally, function zones that use permits more effective will gain more allocation. And the larger the value of per permit, the more allocation function zones that use permits more effective can get.Second, construct allocation model of initial permits among polluters based on market mechanism and draw some conclusions. To begin with, under equilibrium, sewage treatment price must be equal to emission permit price, and polluters will buy the same quantity of emission permits as quantity of outsourcing sewage treatment. Quantity of inner pollution abatement is positive to emission permit price. Quantity of outsource sewage treatment and emission permit purchase are negative to emission permit price. Additionally, pollution quantity that sewage treatment plants decide to treat is positive to emission permit price and unit amount of government's subsidy. Moreover, four objectives of the government are proposed, and then government can set the price of emission permits.Third, propose executive steps and trade model of emission permit trading based on complex relationship network and draw some conclusions. To begin with, permits purchase information of the buyer can spread extensively only if effective propagation is large than the given propagation threshold. Additionally, shortest trading path is defined. With help of the definition, we can gain the potential trading nodes, bringing reduction of transaction costs. Moreover, the dissertation proposes four kinds of model based on whether there exists competition between the buyer and the seller and whether they need intermediate organization. The dissertation pays more attention to researching on model that there isn't competition between the buyer and the seller. And then the dissertation researches on optimal trading quantity and optimal trading price.Four, discuss technology incentive effect of emission trading policy. It is mainly about how to allocate limited R&D investments to green production technology and terminal pollution abatement technology in order to maximize benefits. According to research, the dissertation draws some conclusions. Firstly, product price should be larger than margin production cost and margin pollution fee. Pollution fee should be less than inner pollution abatement costs. Sum of yield return, sales revenue that is from investment in technology R&D, and cost reduction that is from investment in technology R&D should be larger than margin pollution fee reduction that is from investment in technology R&D. Moreover, the dissertation analyzes what affect pollution abatement quantity, and optimal R&D investment in green production technology and in terminal pollution abatement technology in detail.Five, the dissertation researches on topological structure of pollution network and constructs pollution network of four urban districts of Qingdao. And with help of UCINET, Pajek, and MATLAB, the dissertation verifies that small-world feature and scale-free feature are characteristic of pollution network.Six, in the case study, the dissertation summarizes basic conditions of generalized Bohai sea area. And it also researches on initial emission permits allocation of Xiaoqing River. Optimal emission permits abatement quantity and optimal allocation project are also given.Researches in the dissertation help to develop and perfect emission permits trading theory in our country. Conclusions also instruct implementation of emission permits trading in our country.
