2013 年1-2月我国锅炉及原动设备制造工业销售产值达586.22亿元，同比增长4.53%。通过对比六省（市）锅炉及原动设备制造工业销售产值不难看出，52.99亿元锅炉及原动设备制造工业销售产值使上海市在所列举省（市）中脱颖而出，湖北、河南分别以30.04、29.67亿元销售产值紧随其后。就部分地区的电站锅炉与工业锅炉产量进行分析，近年来国内锅炉行业虽在国家利好政策的刺激下上演着以节能减排为核心的转型升级，但就2013年1-2月锅炉产量而言，大部分地区呈下游走势；在所列举地区中，更是仅有河北省实现着锅炉产量的正增长，其他地区均呈现出不同幅度的负增长；其中以安徽省的工业锅炉产量尤为显著。

Elevators and escalators enable swift and easy movement of people and freight within building premises. They are installed in commercial buildings, residential buildings, mixed-use buildings, IT parks, hotels, restaurants, and retail outlets. They are also installed in public places for enhanced vehicle parking management.

The market is fragmented with the presence of a large number of international and regional vendors. The market is expected to grow at a CAGR of 10.20 percent during the period 2012-2016.

根据欧洲电梯协会的估计，欧洲电梯目前70%梯龄超过10年，45%梯龄超过20年。欧洲人口密度较美国高，电梯占全球存量接近50%。存量大且梯龄老，是电梯服务市场壮大的必要条件。全球市场份额来看，奥的斯、迅达和通力是最大的三家电梯公司，合计市场份额接近45%。我们很惊讶地发现，三家公司的市值合计接近人民币3600亿元。中国电梯行业被经常看作和地产高度相关的夕阳行业，并给予10-12倍的低PE。海外领先的三大电梯企业市值均超千亿元人民币，而国内电梯企业市值均在75亿以下。中国目前500家电梯厂，过于分散的市场结构是公众安全的重大威胁，风险将随着90年代建筑的老龄化而逐渐暴露。未来无论通过行政立法还是市场竞争，这个产业都会慢慢走向集中。广日股份等领先企业近年收入增速比行业高一倍，我们预计这种集中会持续，并将会因某些意外而加速。

An air compressor is a machine that takes in air at atmospheric pressure and delivers it at a higher pressure. Air compressors are used in several areas such as commercial businesses, jet engines, as well as in the Manufacturing, Chemical, and Petroleum industries. They are classified into three major types based on the design and principle of operation into piston compressors, screw compressors, and centrifugal compressors.The Air Compressor market in China is expected to grow at a rapid rate during the period 2012-2016. This is mainly attributed to the increasing urbanization and industrialization in the country.As a result, China is expected to play a major role in growth of the Global Air Compressor market during the next few years. The Air Compressor market in China is expected to grow at a CAGR of 14.84 percent during the forecast period.
