中国近20余年中的经济发展速度,如果从其国民生产总值的角度来衡量,一直以比北美或欧洲快2.5倍的速度发展。据预测,在今后20年中,中国将是世界上经济发展规模最大的国家。根据波音公司的统计,在过去17年中,中国的空运业年均增长率达22％。年度载运率已经达到了其现有民航系统载运能力的80％～90％,目前限制其继续增长的主要因素主要是机场和空中交通管制系统的容量不足。为了满足未来的发展需求,中国预期到2015年共计要采购价值1400亿美
The speed of economic development in China in the last 20 years or more, if measured from the perspective of its gross national product, has been growing at a rate 2.5 times faster than in North America or Europe. It is predicted that in the next 20 years, China will be the country with the largest economic development in the world. According to Boeing’s statistics, in the past 17 years, China’s air transportation industry has grown at an average annual rate of 22%. The annual loading rate has reached 80% to 90% of the capacity of its existing civil aviation system. The main factors that limit its continued growth are mainly the insufficient capacity of airports and air traffic control systems. In order to meet future development needs, China expects to purchase a total value of 140 billion U.S. dollars by 2015
