航空工业是综合国力的象征，是国防的极为重要的组成部分。它也是国家安全的重要保证，是经济社会发展的重要支撑。在整个航空工业中，民用航空是由除军事用途以外的各种航空活动组成的，包括国防、警察和海关，民用航空包括商业航空和通用航空。近年来，民航业的迅速发展在航空工业中发挥着越来越重要的作用。
在全球化方面，航空业主要集中在美国、欧洲、加拿大、澳大利亚等发达地区。随着全球经济的快速发展，许多新兴工业化国家大力发展航空工业的积极性也受到了极大的鼓舞。一些高端制造业，包括航空业，正在从发达国家转向发展中国家，为了满足全球市场的需求，许多发达国家和发展中国家开始了合作。当今世界的经济动荡和金融危机给航空业带来了巨大的冲击，尽管情况有所改善，但预测未来将是非常困难的。作为全球航空业的领导者之一，近年来美国航空业的市场受到了很大的影响。机票价格的下跌、油价的上涨以及反垄断政策的出台，都对美国民航业产生了负面影响。
Background:背景
Aviation industry is a symbol of comprehensive national power and an extremely important part of the national defense. It is also a significant guarantee for national security and an essential support for the development of economic and society. In the entire aviation industry, civil aviation is made up of all types of aviation activities using aircraft except military applications, which includes defense, police and customs, and the civil aviation includes commercial aviation and general aviation. In recent years, the rapid development of civil aviation plays an increasingly important role in the aviation industry.
In terms of globalization, the aviation industry is mainly concentrated in the United States, Europe, Canada, Australia and some other developed regions. Along with the rapid development of the global economy, the enthusiasm for developing aviation industry of many new industrialized countries has also been greatly inspired. A number of high-end manufacturing, including the aviation industry, are shifting from developed countries to developing countries, to meet the global market demand, many developed countries and developing countries began the cooperation. The economic turmoil and financial crisis of the current world has caused a great shock on aviation industry, although the condition is getting improved, it is still very difficult to predict what the future will be. As one of the leaders of the aviation industry all over the world, the market of aviation industry in the United States has been greatly affected in recent years. The fallen price of tickets, rising price of oil, as well as anti-monopoly policy, all have negative impacts on the civil aviation industry in America.
Merger integration is trend of the development of international aviation industry in recent years. There are many examples: In Europe, Air France and KLM Royal Dutch Airlines were merged in 2003; Lufthansa purchased Swiss Air in 2005, and later purchased the Austrian Airlines; British Airways and Iberia Airlines merged in 2010 . After a series of mergers and reorganizations, the market is full of vitality and competitive power. In the United States in recent years, the operation of civil aviation industry has become much more difficult and many airline companies are seeking to break through this condition by mergers and acquisitions. In 2005, US Airways merged America West Airlines; Delta Air Lines purchased Northwest Airlines in 2008; two years later, the United Airlines and Continental Airlines were merged and turned into the United Continental Holdings incorporated; in 2011, Southwest Airlines purchased the AirTran and after two years, American Airlines merged US Airways. After the mergers and reorganizations, these companies' operating performance begins to rise out of recession, but whether the specific results really are optimistic? This dissertation will make analysis and judgment.
Congress reduced the control of the market in 1978, which brought the US economy market unparalleled interests. America has a mature aviation industry market, which has become an important factor of the growth of economy now. Even if there is a little change in the industry, it can bring a big influence on various aspects. In this tough competitive environment at home and abroad, the civil aviation industry attracts much more attention.
Concentration Tendency 集中趋势
In recent years, the aviation industry in the United States had generated a lot of new companies and there have been a lot of bankruptcy and merger phenomena, which is bound to affect the competition tendency of the aviation industry. In this dissertation, the methods used to calculate the concentration of aviation industry are Herfindahl-Hirschman Index (HHI) and Concentration Ratio (CRn).
The calculation method of industry concentration index is the most common, and it is also an important indicator of measuring the market structure. It indicates the degree of concentration of the industry by calculating the proportion of the relevant value (such as sales, value added, number of employees, total assets, etc.) of the first largest n companies in the industry toward those of the entire industry. For example, CR4 refers to the relevant market share occupied by the four largest enterprises and CR8 means the relevant market share occupied by the eight largest enterprises.
If the CRn is greater, it indicating a higher degree of concentration of the industry and the more likely for competition in the market tend to be monopolistic; on the contrary, the lower the concentration is, the more likely for competition in the market tend to be competitive.(MBAlib, 2012)
The formula is: CRn=. In this formula, Si means the market share of the enterprise i, n means the total number of firms (for instance, the number is 4 or 8.) in the industry.
However, the disadvantage of CRn is that this concentration ratio cannot indicate the total number of enterprises which are operating and competitive in this industry. For example, the market share of 2 CR4 with the same value of 75% in two different industries might not be the same, because there may be only a few companies in one industry and the other industry may have many companies. Therefore, in the dissertation, HHI will be used to measure the market concentration to improve the credibility of the data.
HHI calculates the sum of the squares of market share of the largest 50 companies in this industry (if the number of companies is less than 50, it includes all enterprises). Obviously, the greater HHI is, the higher the degree of market concentration and the higher the degree of monopoly. The index can not only reflect the market share of large enterprises, but also can reflect the market structure besides large enterprises. Therefore, HHI is able to reflect the impact of large enterprises on the market more accurately.
The formula is: HHI=2. In this formula, Si means the market share of the enterprise i, n means the total number of firms in the industry. HHI changes between 1/n and 1, which indicates that the higher value is, the greater unevenness distribution of the size of a firm. As long as firms merge, the value of HHI will increase; as long as the firms decompose, the value of HHI will be reduced.
The advantage of HHI are it reflects large-scale companies' market share more sensitively, while reflects many small businesses’ market share very little, and it cannot be affected by the number of companies and the size distribution of the industry, which is better to measure the changes in the market concentration of the industry.(MBAlib, 2010)
This table illustrates the values of CR4, CR8 and HHI in ten years. According to the concentration ratio CR4 and CR8, it can be obviously found that the aviation industry was behaving as an oligopoly and was a highly concentrated industry, while in terms of HHI, the market concentration was moderate. All of the 3 values were keeping decreasing from 2001 to 2006 and appeared to hit bottom in 2007, in which year the economy crisis took place. After that, the tendency of market concentration was improved and reached a new height in 2013. (Ahren J. 2011)
In summary, the level of market concentration of aviation industry was decreasing first and then keeping increasing in the United States. Accordingly, the competition tendency also turned from competitive to monopolistic, which indicates the number of companies was reduced and the market shares of large firms have increased.
