The Waste of Public Construction Energy in the City of Beijing, Tianjin and Shanghai is Startling
Beijing,Tianjin and Shanghai are oversize city with numerous populations,lacking resources and relatively limited environmental capacity. The lacking of resource has been the major problem that baffles the development of these cities and threatens city security.
Although there is now a series of outcomes of saving resources in Beijing,Tianjin and Shanghai. The GDP synthetic index and the consumption of water of Shanghai is in the lead all through the country,and Beijing has began to draw up scheme for developing an economy society. But some resources are most devoid in the process of city development,such as water,electricity and natural gas,but they are wasted seriously,which is startling. The traditional economy growth pattern and resource consumption concept have not transformed foundationally. The phenomenon of excessive consumption and excessive extravagance could be seen everywhere.
The total resource consumptions in Beijing,Tianjin and Shanghai occupied the front items in the list of all big cities all over the country. In 2004,the amounts of Shanghai and Beijing are respectively the first and the second. As cities with vast resource consumption,the three cities are typical dependent provision cities,of which resource consumption dependence degree is deep.
京津沪都是人口众多、资源短缺、环境容量相对有限的特大型城市，尤其近年来伴随着经济高速发展和人口规模膨胀，资源短缺已成为阻碍这些城市发展、威胁城市安全的首要问题。
尽管目前京津沪在资源节约方面已取得一系列成果，如上海的万元GDP综合能耗、取水量等指标全国领先，北京已着手制订建设节约型社会规划纲要，但在城市发展最为短缺的水、电、气等领域，“漫灌”式、粗放型的资源浪费现象比较严重，令人吃惊。传统的经济增长模式和资源消费观念还没有从根本上改变，“高消耗”伴随“高浪费”的现象随处可见。
北京、上海、天津的能源消费总量长期在全国各大城市中位于前列，其中2004年上海能源消费总量为全国第一，北京位居第二。作为资源消费特大型城市，京津沪同时又属于典型的供应依赖型城市，资源消费对外部的依赖程度极高。
