Colour Building Components Sector Development Driven Great Countryside – Creating Materials To The
File No. 2010 clearly central to seize the existing fast development of rural housing and building components provide ample chance to support the farmers housing as an critical measure to expand domestic demand and adopt powerful measures to promote the creating components to the countryside. As the housing building for a fantastic driving force of the national economy, the sector pointed out that this year’s capital development, expand domestic demand, the most significant bright spot, constructing components to the countryside will become this year’s construction, creating components business as the “crucial.” The countryside by creating materials, will drastically promote the building of new countryside, stimulate domestic demand and market the building and developing materials business, upgrading of the structure.
Building components to the countryside, a large marketplace
To address worldwide Economic Crisis and financial downturn, the state introduced a package of measures to stimulate financial development. Among this year’s initial document specified by the creating components to rural places of the National Economy in fairly a lot.
According to statistics, as of the end of 2008, the existing rural residential houses a total location of 23.three billion square meters the 2008 National Farmers new housing area of 844 million square meters, of which 786 million square meters of residential. Rural residents each and every year for housing and housing repair, maintenance spending practically 500 billion yuan, of which most of the material consumption. In 2007, China Creating Materials Business Arranging Research Institute, “a nicely-off residential construction demand for building supplies sector analysis” subject study, the current National Farmers housing building area of 120 square meters on average ~ 130 square meters, the typical consumption per square meter major creating quantity of material in general is: .2 tons of cement, steel merchandise .03 tons, plate glass .2 square meters, equivalent to the standard brick wall material 200, floor tiles and wall tile .four m2, sanitary ware .03. Therefore, rural housing construction on the creating material sector, pulling impact is large.
The sector say that the implementation of developing supplies to rural areas, by way of monetary subsidies and other policy assistance, housing and housing consumption to guide farmers scientific, rational growth, such as farmers can stimulate growth in housing based on the original 10% to 15% can stimulate domestic consumption each and every year 550 billion yuan ~ 600 billion yuan.
2010 1 15, China Constructing Materials Federation Ministry of Business and submitted to the “expansion policy and the implementation of the proposed constructing components to the countryside” (hereinafter referred to as the “Proposal”). “Proposals” ought to adhere to the example of Agricultural Machinery Subsidy Home Appliances Approach to rural areas, subsidies to farmers in proportion to the monetary capital spending policies to promote the constructing materials to rural areas, farmers direct subsidies for housing building. In this regard, China Building Materials Federation of artificial Zhang said that farmers under the present housing predicament of the nation, such as consideration by the proposed subsidy system is anticipated to normally call for financial subsidies each and every year about 50 billion yuan and 600 billion, requiring a total of three years monetary subsidies to fund 150 billion yuan to 1800 billion yuan, will allow the nation 15 million ~ 20 million, about 60 million ~ 80 million farmers to advantage farmers is expected to enhance housing building components and consumer of about 1.8 trillion yuan. Housing is completed, it will properly pull decoration Decoration , House Gear, residence appliances, customer comply with-up, will bring results far beyond the scope of material consumption.
