Analysis From The Perspective Of Building The National Economy Based On The Cost Of Garbage Disposal Effect

China began to carry out the legislation for the disposal of construction waste relatedissues from1992to the present, our country has made the study of the three aspects ofecological environment construction waste disposal, recycling and economic benefits, andin practice. In this process, China’s treatment of construction waste has piled up in the openair, landfill and recycling three stages; the first two stages will cause pollution to theecological environment, and recycling of construction waste can effectively solve theproblem of pollution.This paper is based on the economic perspective, combined with construction wasteand related concepts and theoretical analysis of national economy, respectively from theconstruction waste reduction, construction waste landfill and construction waste recyclingthree of construction waste treatment and the national economy. Construction wastereduction through the strengthening design and construction management, to reducenational saving construction waste, construction waste disposal costs can be used foreducation, medical and transportation, so as to promote the development of nationaleconomy; construction waste landfill process will result in the ecological environment isoccupied in and around the destruction of the land mass, which affects the agricultural, to anegative impact on the national economy; construction waste recycling through the use ofconstruction waste reduction on the regeneration of construction waste, a new industrialchain is formed in this process, to promote national economic development. Through theabove analysis, the construction waste recycling is the most scientific, the most effectiveand with China is now national policy of construction waste treatment method. The effectof using cost method, the direct costs of construction waste recycling define, direct effect,indirect cost analysis of definition and indirect effect. The direct cost is defined thedefinition of fixed assets, land circulating fund, construction period interest, product costand sale cost; direct effect analysis of main construction waste resources and economicfeasibility analysis; indirect costs to define the process from the construction wastetransport to the building garbage resource cost definition; indirect effect to define the maineffect from two aspects of the definition of ecological environment and land. Finallycombining the resources of Du jiang yan construction waste plant for case analysis, itmainly analyzes from two aspects of economy and national economy.The innovation point of this paper is from the overall situation of national economybased on the perspective of construction waste treatment, single different from previous economic benefit as the basic point of view; using cost-effectiveness method quantitativedefinition of the disposal of construction waste, in the indirect effects defined, taking landas the main index, to quantify the the influence of the cultivated land of construction wastein a certain range, the currency of the direct costs and indirect effect of quantization, youcan use the cost-effectiveness ratio derived specific figures, analysis of the impact ofconstruction waste disposal of the national economy.Future research direction mainly from the protection of the ecological environment,reduce construction waste, national economy and economy of the four aspects ofconstruction waste recycling.
