I. History of the World Expo and Historical World Expo The World Expo is not an ordinary commercial exhibition for trade promotion and economic investment promotion. Held for a long time, it has great influence, especially the comprehensive World Expo, which is a grand event for all countries in the world to show their social, economic, cultural, scientific and technological achievements and development prospects. /kloc-In the mid-9th century, the British industrial revolution made remarkable achievements in the past century. In order to show off its powerful national strength, Britain decided to hold the London International Industrial Fair in 185 1 year. In the name of the country, Queen Victoria invited more than ten countries from Europe and America to participate in the Expo through diplomatic channels, and the exhibition lasted 140 days. Exhibit evaluation and craft activities were carried out during the exhibition, with rich and colorful contents, but no direct trading activities were carried out at the Expo, which formed the pattern of hosting the World Expo in various countries in the future. The World Expo was held in Hyde Park in central London. The exhibition hall consists of steel frame and glass curtain wall. This building is called "Crystal Palace". The World Expo shows the achievements of the British industrial revolution, as well as advanced industrial exhibits from various countries, such as 630-ton high-power steam engines, locomotives, high-speed steam boats, steam presses, cranes, advanced steelmaking methods, tunnels, bridges and other large models. Extended 140 days, with more than 6.3 million visitors. 1884, the French lower house parliament decided to hold an exposition in Paris on 1889 to commemorate the 0/00th anniversary of the French Revolution. Only 28 countries (mostly American countries) participated. But this World Expo left a very famous landmark, the Eiffel Tower. The Eiffel Tower, with a height of 300.5 1 m, was the tallest building in the world at that time, and its height record remained until the 1920s. It has been a symbol of Paris for more than a hundred years. Since then, metal materials and reinforced concrete structures have been widely used as building materials, and the height of buildings has been increasing. Different from the exhibition of industrial technology in the first World Expo in Britain, this World Expo is rich in humanistic content, including political and economic pavilions, as well as tool history pavilions ranging from stone age axes to modern physical instruments. Today's "May Day International Labor Day", which is popular all over the world, was decided at the social conference held during this World Expo. The closure of 1 October 3 1,1had to be postponed for one week. The total number of visitors reached 32 million, which is also profitable economically. 1933, the United States hosted the Chicago World Expo to celebrate the100th anniversary of the founding of Chicago. The background of this World Expo is that the United States began to recover from the economic depression in the 1930s. A total of 47 countries participated in the exhibition and 38.3 million tourists visited. There are two original works in this World Expo, which have become the practice of subsequent World Expo. One is to put forward the theme of "one hundred years' progress". Since then, all the World Expositions have a definite theme. The other is to allow some large enterprises to set up special exhibition halls, such as GM, Ford, Chrysler and other automobile companies. This practice is very popular with entrepreneurs and tourists, creating a history of large enterprises building special pavilions in the Expo Park. Japan was defeated in World War II. After the war, Japan devoted itself to economic development and national rejuvenation. The Tokyo Olympic Games was held in 1964, which greatly inspired the Japanese nation. 196 4 In June, the Japanese government decided to bid for the Osaka World Expo 1970 and won the right to host it in September 1965. The Osaka World Expo attracted 76 countries and 4 international organizations, with more than 64 million visitors, making it the most visited World Expo in history. This World Expo has greatly promoted the construction of transportation, high-grade housing, commercial facilities, tourism and cultural exchange places in Osaka, and promoted the formation of Kansai urban agglomeration with Osaka as the center. It is of great significance to Japan's economic development and layout. From the landmark World Expo listed above, we can see the significance of hosting the World Expo in various countries. First of all, the economic significance of hosting the World Expo is that it can concentrate various production factors in a specific period and region, realize the optimal allocation of economic resources, and accelerate the long-term development of a region. This is the motivation for hosting most world expositions so far. There are many examples of this. For example, World Expo Montreal 1967 accelerated the construction of new subway system and expanded the suburban expressway network. Although the operating company of the 2000 World Expo in Hanover, Germany suffered losses, it brought huge economic benefits to the country: it created 654.38+million employment opportunities for Germany, enhanced Germany's international reputation, improved Germany's investment environment, promoted consumer demand and brought additional taxes. Secondly, the significance of science and technology culture. The World Expo has promoted the entry of modern science and technology into human life. Many new technologies, new products and new lifestyles have been recognized and promoted at the World Expo. At the 1876 World Expo in Philadelphia, USA, the telephone invented by Bell, the telegraph and phonograph invented by Edison, and the improved bicycle and typewriter all met the world for the first time. The World Expo in Paris 1878 shows the tungsten filament incandescent lamp invented by Edison. There is also a large balloon with a volume of 35,000 cubic meters, which can send 50 spectators to an altitude of 1000 meters. In the mechanical exhibition hall of 1889 Paris World Expo, the most popular one is the booth invented by Edison. People have to wait in line for two or three hours to hear the phonograph. 1893 The international electrotechnics conference held in the Chicago World Expo decided on the measurement names of ohm, ampere, volt, joule, watt and other electrical appliances. The world's first "entertainment wheel" also appeared at this World Expo. 1986, American World Science magazine selected 10 from thousands of inventions recommended by readers, and the zipper ranked first, and its first appearance was 1893 Chicago World Expo. The most popular movies at the Paris 1900 World Expo in France are those recorded synchronously, as well as other telescopes with magnification of 1000 times, the first radio transceiver, Otis elevator, X-ray instruments and so on. 1904 The World Expo in St. Louis, USA shows tube radios, automatic telephone exchanges and electric buses. Nowadays, hamburgers, sausage bread and ice cream, which are popular in the world, were first sold publicly at this World Expo. Another magical exhibit of this World Expo is the airplane. 1at the end of 903, the Wright brothers of the United States made their first flight successfully. The exhibition of World Expo 1904 announced that mankind has entered the aviation era. The Chicago World Expo 1926 showed the most advanced industrial technology at that time, such as new automobile assembly line, shipbuilding technology, air conditioning equipment, crude oil refining technology and so on. Expo 1937 in Paris, France, shows the first batch of televisions in the world, which can show the glass mannequins of human blood flow and the work of major organs. 1939 The TV broadcast of the opening ceremony of the World Expo in new york, USA, is the first time for Americans to watch TV. At the Expo, nylon, plastics, tape recorders, tapes and other products that have an important impact on people's lives were also exhibited. General Motors built a "future city model" at the World Expo. When people enter this model, they can experience the life scene in new york within 15 minutes. 1969 On July 20th, American astronauts landed on the moon successfully. At the 1970 Osaka World Expo, the moonstone brought back by American astronauts became the most striking exhibit. The third is political significance. Political significance refers to the role of showing the national image of the host country to the outside world and condensing the national spirit at home. 185 1 The first modern World Expo held in Britain was basically to show the achievements of the British industrial revolution and its position as a leader of various countries. America's attitude towards the World Expo is worth studying. /kloc-In the mid-9th century, the United States was eager to show the world its rise as a young country. From 65438 to 0853, the second World Expo was held in new york, USA. From that time to the 1980s, the United States hosted the14th World Expo, becoming the country that hosted the World Expo the most times. Germany and Japan are another example. The reason why these two countries are keen on hosting the World Expo is that they want to get rid of the shadow of the defeated country, which is also of political significance. Japan hosted the first World Expo in 1970. Osaka people, local organizations and enterprises are proud of being among the world powers, orderly and popular. The number of visitors has set a record. After Germany won the right to host the World Expo in 2000, Premier Schroeder clearly pointed out that this was the first time that Germany hosted the World Expo, which was a good opportunity to show the image of Germany after reunification to the world, thus showing the world the image of an open, literate country and a modern economic zone.
