Research On Transboundary Pollution Control Stractegy Of Carbon Capture And Storage Technology Under Learning-by-doing

Controlling the excessive accumulation of greenhouse gases such as carbon dioxide,which spread across borders,has become an important issue concerning the fate of mankind.Based on the analysis of relevant literature at home and abroad,the control of transboundary carbon pollution through carbon capture and storage(CCS)is studied in depth.Firstly,a differential game model of cross-border pollution control under CSS mechanism is established,in which the instantaneous CCS in two neighboring countries are taken as control variables and the carbon dioxide stock as state variables.Using dynamic optimization theory,Nash equilibrium solutions under three game modes of open-loop strategy,Markov strategy and cooperative strategy are solved,and Nash equilibrium solutions under three strategies are compared and analyzed.Secondly,Considering that countries can improve their carbon capture level through technology investment,a differential game model of endogenous transboundary pollution control in carbon capturetechnology is established.Nash equilibrium solutions under three strategies,open-loop strategy,Markov strategy and cooperative strategy,are solved respectively,and Nash equilibrium solutions under three strategies are compared and analyzed.Thirdly,Considering the national investment in carbon sequestration technology,a differential game model of endogenous transboundary pollution control in carbon sequestration technology is established.Nash equilibrium solutions under short-term(assuming that the instantaneous emission of carbon dioxide is constant)and long-term(assuming that the instantaneous emission of carbon dioxide changes steadily)open-loop strategy and Markov strategy are solved respectively,and Nash equilibrium solutions under the two strategies are compared and analyzed.The results of the model study show that:Firstly,the learning-by-doing effect has an important impact on the national cross-border pollution control behavior.With the increase of knowledge accumulation,the cost of carbon capture and storage decreases.In addition,the improvement of knowledge accumulation efficiency promotes more carbon capture and storage investments by game participants,and thus has a better ecological environment.Secondly,the learning-by-doing effect can compensate for part of technology investment,because with the increase of learning rate ofknowledge accumulation,the growth rate of carbon capture and storage technology investment is declining.Thirdly,if the game participants carry out open-loop strategy,Markov strategy and cooperation strategy respectively,the amount of carbon dioxide captured and sequestered under the cooperative strategy is the largest,followed by Markov strategy,and the amount of carbon dioxide captured and sequestered under the open-loop strategy is the smallest.Therefore,the environmental quality under the cooperative strategy is the highest,followed by that under the Markov strategy,and that under the open-loop strategy is the worst.
