“十二五”规划纲要中明确指出,2011-2015年期间预计完成保障性住房以及棚户区改造住房3600万套,在这当中2011年全国已实现开工1000万套。在全国范围内大规模建设保障性安居工程,既是推动我国科学发展、加快转变传统的经济发展方式的具体实践,同时对社会,对实体经济也具有重大的现实意义和极其深远的历史影响。 In the “12th Five-Year Plan”, it is clear that during the period 2011-2015, it is estimated that 36 million units will be completed in affordable housing and shantytowns, of which 10 million units have been started in 2011 in China. Large-scale nationwide construction of affordable housing projects is not only a concrete practice of promoting China’s scientific development and accelerating the transformation of traditional economic development modes, but also of great practical significance and far-reaching historical impact on the society and the real economy.
