Study On China’s Low-carbon Economic Development System

As the contradictions among resources, environment and economic development areincreasingly outstanding，human is facing innovation of economic development mode in the21st century. The low carbon economy featured by low material consumption, low emissionand low pollution, is a new choice of the economic development mode in the future. China isfacing large pressure on ER GHG and energy as well as ecological safety is threatened.Taking the path of a low carbon economy makes a great contribution to the worldwideenvironmental cooperation, in line with China’s national conditions of converting theeconomic increasing method.Therefore, it is imperative for the new developing situation ofthe country to establish low-carbon economy development system based on the analyses of itspotential.Establish a low-carbon economic development model. According to the definition andcharacteristics of the concept of low-carbon economic development system, low-carboneconomic development elements analyzed and summarized15elements, constructedaccording to the relationship between the elements of the system, the elements of therelationship model. Using gray system model estimates in2020China’s low-carbon economicdevelopment goals, and then, according to the means of goal theory of systems engineeringand the carbon cycle is divided into a subsystem of the energy structure adjustment, energysaving and emission reduction subsystem, carbon sequestration and storage subsystemand environment supporting subsystem four subsystems, and analyzed the relationshipbetween the subsystems.After we set a low-carbon economic development goals, the application of econometricmethods to calculate the path of goals, estimates of the industrial structure, energy structure,the contribution of low-carbon technologies for low-carbon economic development goals toachieve, measured the parameters of the scientific significance of the contribution, andmeasures the level of industrial structure and energy structure to achieve the goal of low-carbon economic development system.Constraints of low-carbon economic development goals of energy conservation andemission reduction subsystem, defined energy saving subsystem elements、 structure andfunction, found by analyzing which the main factor is the industrial structure, then empiricalanalysis the direction of industrial structure adjust. Path analysis and quantitative analysis ofthe structure between the three industries, and then use the panel cointegration model depthanalysis and comparison of internal industry structure of the secondary industry, and pointedout the direction for three industrial structure as well as the internal restructuring of the secondary industry.Constraints objectives in the development of low-carbon economy system, establishedthe energy structure adjustment subsystem, defined the elements of the structure and functionof the subsystem energy structure adjustment. Social network analysis methods to measurethe current energy adjustment, to identify the direction of the energy structure adjustment, andthe constraints of the system objectives of the development of low-carbon economy,estimated in2020China’s energy structure adjustment station.Constraints objectives in the development of low-carbon economy system, established ofa carbon absorption and storage subsystems, and defined the elements of the structure andfunction of carbon absorption and storage subsystems. Under the constraints of the low-carbon economic development goals, estimated of biological carbon sequestration and carbonabsorption and storage of the contribution to the development of low-carboneconomy. Because of the importance of carbon sequestration and storage technology in thedevelopment of low-carbon economy, built carbon sequestration and storage technologyproject evaluation index system, and eigenvalue method of group decision-making with fuzzycomprehensive evaluation method, analytic hierarchy process combine to build acomprehensive evaluation model for carbon sequestration and storage projects, to provide thebasis for the government to support low-carbon technology projects.In environment supporting subsystem, it analyzes environment mainly from governmentenvironmental support (including legal environment and policy environment), financialenvironmental support, culture environmental support and infrastructure environmentalsupport, in order to provide better environment support for the development of low-carboneconomy.Finally, On the basis of the analysis of low-carbon economy development system, thispaper makes a performance evaluation of low-carbon economic development system of theprovince. It establishes a performance evaluation index system based on DEA covering foursubsystems indicators, and demonstrates using the data of the provinces and cities in Chinafor the samples。Then, using the unit root test model analyses the convergence of the percapita carbon emissions.According to the analysis and evaluation of the results, it proposessome countermeasures in the development of China’s regional low-carbon economydevelopment system.
