Study On Recycle Economy Of Guangdong Province Based On The Material Flow Accounting

This study is based on national material flow accounting Eurostat (2001) proposed and form the regional material flow accounting framework and indicator system, applied to the environment in Guangdong Province in the economy system, building material flow accounts in Guangdong Province. On this basis, the accounting data combined with socio-economic class of indicators of material flow analysis, using method of IPAT analysis regional emissions to reflect contribution of demographic, economic and technological factors, reflecting the relationship between environmental pollution and economic development by KFC theory, providing countermeasures and suggestions for circular economy. Based on the above analysis conclude, during the period 2000-2008:Firstly, per capita industrial waste water and per capita industrial solid waste emissions inverted "U" type with per capita income, meet the KFC, and per capita Industrial emissions and per capita income basically meet the KFC. With the upgrading of industrial structure and technological progress, environmental pollution has reached a turning point in the next under the safety limits of environmental capacity, environmental pressures eased. Through the IPAT we can find that the process of regional emissions are mainly due to the increasing technical level constraints eased, but growing with driving of the national welfare and population.Secondly, intensity of material consumption within the region is twice the national average consumption level, close to the level of developed countries. Substance use efficiency close to the level of developed countries nineties. Region of material input and output intensity grow rates of 3.78% and 1.44% average annual, and material input and emission of Unit of GDP unit decline 6.40% and 6.94% annual, productivity and the living standards have increased.Third, material inputs continue to increase, while output has continued to rise, Material needs mainly major in industrial minerals and construction minerals enter, industry-based economic growth is the main, agriculture dominate in the primary industry, on the contribution of biomass every year to maintain more than 70%. Solid waste pollution is serious, and is based mainly domestic garbage, damage of sulfur dioxide is still relatively large, although the growth rate slow, but emissions are still large, industrial dust achieved results, decrease 65.96%. The harm of dissipation is more serious, in this period, it nearly doubled the amount, increasing environmental pressures, Guangdong's rapid economic growth in resource consumption and environmental damage a large number of the expense to achieve, economy growth is mainly dependent on outside imports.Fourth, foreign demand is mainly of energy-based, import materials are mainly of fossil fuel-based, more than 80% every year. In this period there are a large number of infrastructure and housing construction, the needs of industrial minerals and construction minerals is the fastest, Increased by nearly 3 times. Equally divided between fossil fuels and mining products in the export of material, only a tiny fraction of biological export.Fifth, enter the amount of water was stable in the growth and maintain at 230 million tons, Sewage is more than industrial waste water in the waste water, But the emissions of industrial wastewater increased substantially, because of industrial development in Guangdong Province is discharging a large number of industrial waste water.Based on the above conclusions, improve resource use efficiency, reduce waste emissions, conservation and reuse resources, alleviate the economic contradictions between development and the environment, maximization of economic returns, they are very important for the circular economy in the Guangdong Province.
