Material Flow Analysis In Macao And Its Application In Low-Carbon Economy

Proposing the city orientation of "Low-Carbon Macao", this paper taken material flow accounting as a tool, made use of material flow analysis in Macao's planning of environmental protection, discussed material flow of Macao, drew Macao carbon flow chart of energy consumption in 2009, finds out the major influence factors and development potential of Macao's low-carbon economy, then, proposed the main policy security system of developing low-carbon economy, provided some reference for identifying the target of developing low-carbon economy.Firstly, this paper developed the thinking of theory and method, and built system of area material flow accounting and research method that on the base of Eurostat(2001). Secondly, it accounted Macao's material flow specifically with quantitative analysis, realized the resource pressure, environment pressure and operational efficiency of Macao's economic growth. Finally, it drew Macao carbon flow chart of energy consumption, discussed and proposed path of developing low-carbon economy, mainly.Research shows that in thirteen years(1997-2009), macao:With the development of social economy, the input and output of material (no water) and water increased more and more(annual rate of increase was 3.21%,3.57%,3.77%,0.79%), displayed in the heavy demand of import material and the discharge of solid waste mainly. In the condition of no water, the material input of Macao was well linear relevant to GDP. When the coefficient of elasticity(2.5399) of GDP compare to material input was greater than l,this declared the super-speed rise of Macao's economic depended on the super-speed rise of natural resources consuming and environmental pollution heavily, and the dependment level of economic growth that needing resource was greater than environmental pollution.The input and output of water per GDP, input and output of material per GDP (no water) displays the trend that rose before return and fell after that. The annual progressively reducing was 18%,9.9%,5.54%,5.19%.This declared that the resource utilization ratio and waste manage efficiency increase step by step after Macao's return to the motherland, and Macao had the huge sustainable development potential. The input of material was well linear relevant to output, and the coefficient of elasticity of input compare to output was 0.4031,this declared that compared with environmental pollution's manage, lower material input from head was the fundamental method of harmonizing economic growth, environment protecting relation and achieve sustainable development.The policy advises of developing Macao's low-carbon economic:On saving resource, strengthening environmental education, broadcasting green living mode, enlarging waste resources recovery and circulating using method, and spreading and using renewable resources; On green commuting, broadcasting Green commuting mode and studying to reduce automobile exhaust pollution; On low-carbon enterprises respect, carrying out cleaner production technology, and spreading environmental protection and energy conservation production.
