【正文】 riosity and desire to raise tennis culture, both radar and “eagle eye” playback are applied in tennis match, thus providing a rational sense of tennis match both for the players and the audience. In addition, the western prosperous tennis petitions are always held in festival atmosphere, there are tennis theme park, architecture, tennis court, party, graffiti salon and even the nicknames for the tennis players given by their fans, all of them show the harmonious bination of westerner’s life and tennis. The cultivation of backup talents has great influence on the sustainable development for each sport, and it works for tennis too. Westerner countries has unparalleled advantages in tennis petition field, one important reason for this is that it attaches great importance to the cultivation of backup tennis talents, and in the many years of professionalization, a series of relatively perfect backup personnel training mode is established, from qualification admittance of the coaches to the athletes selection standard, from the training funding sources of the athletes to the junior tennis event management as well as related professional books, all of it reflects the systematiess, rigor, scientific nature and rationality of the tennis backup training in western countries.III The difference of tennis between China and West in economy aspect Influence of Chinese economy on tennis developmentEver since the reform and open up policies, China has put on a new appearance. When it es to this, we will have to talk about China’s economy. Economy is the foundation to the survival of a country, there is no doubt that the economy of China is booming in recent years, the takingoff economy has enhanced China’s prehensive national strength, the marketing economy is booming and people’s living standard has improved a lot. But under the influence of the recent year’s international crises, the growth of the economy has slowed down, and it has affected people’s life in various ways, including people’s recreational activities. As we all know, china had been falling behind the western countries for decades. Although the economy of china is booming these years, China is still a developing country. Comparing with industrialized western countries, Chinese people couldn’t afford too much on sport activities, they have to work hard to support the family, there is no government aids. And because of that, Chinese people usually spend more money on food and electronic goods. In these years, parents prefer to spend money on their kids education, taking them to extracurricular math class or English class or piano class. They don’t like children to spend too much time on sports to them, there are already so many athletes now, it is difficult to bee famous, and it is all about money. As early as the 1920s, athletes from Europe and America had begun to make money by playing sports. When tennis parted from the Olympic games, the tennis professionalization of Europe and America had lasted for years, and it was not until the ing of the 1960s that this professionalization had got a plete and mature market. This process itself was very hard, but it is mainstream development direction of modern petitive sports and it made the western tennis rocket to the sky. It is no exaggeration that in the several decades of professionalization,tennis has inflicted powerful impact on the social value. But paring our country’s tennis professionalization, the result is kind of disappointing. Most of our tennis lovers don’t take the professionalization way to improve his or hers tennis value.The tennis population of China is kind of small and the tennis foundation is weak. According to recent statistics, the present number of China’s tennis population (it refers to people who play tennis often) is only about 600000, the number of tennis lovers (which including people who are fond of tennis but do not play tennis) is about 40000000. Seeing it from the whole, the tennis population just accounts for % of the total population, tennis lovers account for %, and this reflects a wide gap between China and the western countries. As for tennis population, the number of America reaches to % of the total population, Britain amount to %, France is %, Australia is %, Russia is %, South Korea is % and even India excels China with the figure %[7]. Although there also exist some small cities whose tennis are in a high level, like inner Mongolia Chifeng(with a tennis population of 10000), Tongliao(the number is 8000) and so on, but to see from the whole nation, tennis only are only expanded in some large and mediumsized cities. In terms of the influence that the sports have on the people, tennis is out of the top 20, ranking behind the football, basketball, volleyball, pingpong ball and badminton. It totally lacks the social attention and involvement like the other sports. In order to improve the petitive level and get a higher international ranking, professional athletes have to spend the whole year traveling around the world to participate in the international professional matches, and this cost is usually high. Especially for a sport like tennis, the input of tennis is several times higher than the other sports. Even after the reform and opening up of China, the tennis of China has been booming, still the financial input of stays an important factor that restraint the development of tennis in our country[10]. As the great success of the international tennis tournament operation, the prizes offered by the sponsors are high, tennis players around the world are trying to take part in as many as points races to achieve a much higher ranking place, but lets back to the beginning, the costs for players to go abroad to take part in international games are high, the reason why Chinese female tennis players have made such progress is that our country has put so much money in it, the amount of money that spend on tennis in general is several times higher than the money s
