近几年来,北京的建设任务越来越大,远远超过了建材生产和供应的能力,建筑材料全面紧张,使本来就有的矛盾更加尖锐。因此,在当前严格控制首都基本建设规模的同时,必须采取有力措施加速发展建材工业。一、制约我市建材工业发展的主要因素(一)设备陈旧,工艺落后,技术水平低。能源和原材料消耗大,劳动生产率低。产品品种规格少,档次低,质量差。(二)建材工业投资不断减少,发展规模 In recent years, Beijing’s construction tasks have become increasingly large, far exceeding the ability of building materials to produce and supply, and the overall tension in building materials has made the original contradictions sharper. Therefore, while strictly controlling the capital construction scale of the capital, we must take effective measures to accelerate the development of the building materials industry. First, the main factors constraining the development of the city’s building materials industry (1) outdated equipment, backward technology, low technology level. Energy and raw materials are expensive and labor productivity is low. Product varieties and specifications, low grade, poor quality. (II) Investment in building materials industry continues to decrease, and the scale of development
