The purpose of hosting the World Expo is often to celebrate major historical events or important events in a certain region or country, and to show human achievements in one or more fields such as politics, economy, science and technology, and culture. New technologies, inventions, creations and products that mark the progress and development of human society are presented to the public through the platform of the World Expo.
In 185 1 Great Britain's national industrial works exhibition, the economic achievements brought by the British industrial revolution and the advanced industrial products of participating countries, such as automatic chain spinning machines, high-power steam engines, railway steam tractors, high-speed steam ships, steam presses, cranes, machine tools, advanced steelmaking methods, tunnels and bridges, were exhibited. Concrete, steel, aluminum products and rubber were exhibited at the 1855 Paris World Expo. At the 1862 London World Expo, artificial dyes invented by Germans for dyeing cloth were exhibited. At the 1867 Paris World Expo, new industrial products such as electric lighthouses, submarine cables, hydraulic lifts and ball bearings made their debut. Power loom, water pump, axle, cable, locomotive, printing machine, typewriter, multiplex telegraph, etc. All of them were exhibited at the Philadelphia 1876 World Expo. 1878 At the Paris World Expo, various new inventions were colorful, such as Bell's telephone, Edison's phonograph, freezer and so on, all of which were epoch-making inventions of mankind. 1889 A new type of photographic film with continuous display and clear images was exhibited at the Paris World Expo. Later generations invented the film machine with this technology. A variety of new industrial products such as steam engines and motors were also exhibited; At the 1893 Chicago World Expo, the invention and application of electricity became the most dazzling "star" of this World Expo. For the first time, the Electronic Museum used AC power generation system to provide lighting electricity. 6.5438+0.2 million light bulbs were used, and letters and graphic shapes were blown out with glass tubes, which was the first time that neon lights appeared. 1900, the World Expo "Looking Back at the Century" was held in Paris. The subway was introduced, the scientific and technological achievements of 19 century were displayed, and large generators and radios were exhibited. 1904 America Street? Planes and radios will be on display at the Lewis World Expo; 1933, Chicago, USA hosted the World Expo for the second time. For the first time in the history of the World Expo, the theme was "a century's progress". The striking exhibits at the World Expo are the fruits of aviation research-August? Professor piccard's basket balloon rose to an altitude of 480,000 feet; 1939 —— 1940 At the World Expo in new york, USA, tape recorders, televisions, television cameras, nylon and plastic products appeared. The spacecraft was first exhibited at the professional World Expo in Seattle, USA, in 1962, which indicated that human beings have been able to leave Mother Earth and enter the universe with the help of high-tech power. Osaka World Expo 1970 and Tsukuba Science and Technology Expo 1985 show the audience the development and achievements of Japan in various aspects after World War II. 1986, the newly developed communication products were exhibited at Vancouver Professional Expo. 1993 World Expo Daejeon, Korea, fully demonstrated the rapid development of the Korean economy; The exhibition of the 2000 Hanover World Expo shows that human beings use the power of science and technology to challenge the future and live in harmony with nature, revealing the new relationship among human beings, nature and technology. 2. Explore ways to solve the important problems facing mankind. The World Expo focuses on the same problems faced by mankind. It gives people profound enlightenment by completely showing the development process of things and exploring ways to solve problems. Since its birth, the World Expo has involved issues of common concern to mankind. 1933 The theme of the Chicago World Expo is "the century of progress". Through the exhibition of a large number of new products, it is clearly pointed out that scientific and technological inventions and innovations will become the main driving force for the progress and development of human society in the future. 1939- 1940 held world expositions in new york and San Francisco, with the theme of "building a tomorrow's world" and put forward a new slogan: "human beings are interdependent", so as to build a better tomorrow's world with today's strength and a happy American lifestyle. The first post-war World Expo was held in Brussels on 1958 with the theme of "science, civilization and humanity". Through exhibitions, participating countries reveal the great damage caused by war to human homeland and environment, and call on mankind not to fight, and promote human civilization and harmony with scientific progress. The theme of Osaka World Expo 1970 is "Human progress and harmony", and it is pointed out that cherishing resources and controlling pollution are new problems facing human society. 1974 at the Spokane environmental exposition in the United States, "pollution-free progress" was clearly put forward. The theme of World Expo 2010 1984 in New Orleans, USA is "World Rivers-Water-the Source of Life", which reveals that water is not inexhaustible, and human beings have already faced the problem of water shortage. 1986 Vancouver Expo, with the theme of "Traffic and Communication-Human Development and Future", reminds mankind that it has entered the information age. At the Daejeon Professional Expo in Korea during the period of 1993, the theme of "the challenge of vigorous development-a new way to take off" was put forward in combination with the contents of environmental protection, ecological balance and harmonious development. Various recycling technologies are widely used in the construction of venues and exhibition halls, and the roads in venues are also paved with waste tires. The theme of Expo 2010 1998 in Lisbon, Portugal is "Ocean-Wealth of the Future". Through exhibitions, people are encouraged to continue to explore the secrets of the ocean, develop and utilize the ocean for the benefit of mankind, and at the same time protect marine resources. The theme of Expo 2000 in Hanover, Germany is "Human, Nature, Science and Technology-a New World of Prosperity and Development", which advocates the concept of sustainable development and reuse. The 49 national pavilions participating in the World Expo are all made of environmentally friendly, renewable and multi-purpose materials.
2. The World Expo has promoted political, economic, scientific, technological and cultural exchanges and cooperation among participating countries.
In about half a year of the World Expo, exhibitors from all over the world gathered together to understand, communicate and cooperate with each other. Senior officials from politics, economy, finance, large companies and enterprises from various countries gathered here for high-level exchanges and negotiations. 185 1 Crystal Palace Expo opened, Queen Victoria personally presided over the opening ceremony and cut the ribbon, and visited the Expo with senior officials from political, economic, cultural and other fields around the world. 1855 The Paris World Expo set a precedent for foreign leaders to visit the Expo in person. Afterwards, the host country of the World Expo will generally invite the leaders of the participating countries to visit the World Expo and hold exhibition hall days, or hold cultural week activities of the participating countries, focusing on cultural and artistic performances with their own characteristics, and introduce their historical development, customs, living habits, scientific and technological progress, etc. to the audiences of various countries. There is no direct trade activity in the Expo site, but indirect economic and trade negotiations outside the Expo site are very active. Major multinational companies and enterprises have set up their own museums to display their latest products in the dynamic form of art or "sound, light and electricity" and to show their economic and technological strength, so as to promote their products. 1970 during the osaka world Expo, Japanese enterprises signed export contracts of about $2 billion. 1993 At the Daejeon Professional Expo in South Korea, French President Mitterrand personally presided over the French Pavilion Day to promote the French high-speed train system (TGV) and reached an agreement with South Korea to provide the Seoul-Busan high-speed railway train system, worth 654.38+08 billion US dollars. On 1999 Kunming World Horticultural Exposition, Yunnan Province fully displayed rich species and tourism resources, which played a positive role in promoting flower export and tourism development. At the 2000 Hanover World Expo, Chancellor Schroeder personally accompanied Premier Zhu Rongji to visit the Expo and took the opportunity to promote German products. The two sides finally reached a large-scale economic and trade contract. 2. The World Expo will promote the social and economic development of the host country and the host city, which will help promote the development of the host country in economy, tourism, culture and art exchanges. For the host city, the World Expo often becomes the driving force to promote the construction of urban infrastructure, transportation facilities, urban planning and design, and urban transformation. Through these constructions and transformations, we can improve the construction of urban infrastructure, airports, roads, bridges and other facilities, improve the living environment of urban residents, and form a good ecological environment and cultural atmosphere. When hosting the World Expo, it is generally necessary to build landmark buildings with novel and unique design and new building materials, which not only promotes the development of architectural design and material technology, but also preserves most of these buildings after the World Expo, bearing the imprint of society, culture, science and technology, architecture and aesthetics, and some of them have become symbols of cities and even countries. 185 1 The pavilion of the London World Expo is located in Hyde Park, covering an area of 18 acres. It is the first time to combine steel components, glass and laminated plates in buildings, and it has become the forerunner of modern glass curtain wall high-rise buildings. The whole building is supported by steel frame, and other parts such as roof and wall are assembled by large pieces of glass. The exhibition hall is tall and bright, full of light, and colorful, just like the fairy palace in a dream, and is vividly called the "Crystal Palace". 1854 "Crystal Palace" was moved to Andenham, Xi 'an to hold art exhibitions and concerts, 1936 was destroyed by fire. Paris is the city that has hosted the most World Expositions, leaving behind the most exquisite buildings. The Eiffel Tower is a landmark building that hosted the World Expo in 1889 to commemorate the centenary of the French Revolution. Its height is 32 1 m. It is the father of the modern tower and has become a symbol of Paris and France. The most beautiful Alexander III Bridge on the Seine River, Xiale Palace, Paris Industrial Palace, national mall, Odyssey Palace, Honorary Military Academy, Mechanical Palace, Expo Memorial Gate, Institute of Artificial Art Creation and some buildings on both sides of the Seine River are all important legacies of previous Paris World Expos. As epoch-making landmark buildings, they add elegance and charm to the flowers and have always attracted domestic and foreign tourists to visit. 1933 The landmark building of the Chicago World Expo is "Hundred Cities". Classical architecture, all painted with plaster of Paris, is white and spectacular, especially in the light at night. During the World Expo, most pavilions were temporary buildings and were demolished after the closing. To this end, many new building materials and buildings have been developed, such as inflatable light buildings and plastic canopy buildings. At the 1958 Brussels World Expo, the organizer built a spherical exhibition hall with atomic energy structure, which symbolizes that mankind has entered a new century of scientific and technological progress and has stood in the center of Brussels so far. 1970 the landmark building of osaka world Expo is "Tianyu pavilion", and the top floors of big houses are stacked in layers, which are magnificent and towering into the sky, fully demonstrating the majestic style of oriental palace architecture. The reuse of buildings in Vancouver Expo 1986 and Hanover Expo 2000 was very successful. In preparation for the Lisbon 1998 World Expo, the city's infrastructure such as transportation, telecommunications and environmental protection has been completely renewed. Kunming, which hosted the World Horticultural Exposition 1999, completed the transformation and construction of the city ten years ahead of schedule, and successfully held the Horticultural Exposition with a brand-new urban look. Hosting the World Expo has promoted the tourism development of the host country and city. With the expansion of the scale of the World Expo, the number of visitors has doubled, from 6.3 million for the London World Expo at 185 1 to 64 million for the Osaka World Expo at 1970, and in recent years it has reached more than10 million. The host countries take various measures to improve the ability of gathering tourists and attract tourists from all over the world to visit the World Expo and other famous tourist attractions. London, Paris, Vienna, new york, Osaka and other cities that have hosted the World Expo have become world-famous tourist destinations. Since the World Expo 1976, Montreal has become a famous tourist city in Canada. Seville, Spain, has been transformed into a tourist attraction since the World Expo 1992, attracting a large number of domestic and foreign tourists every year. The horticultural exposition held in Kunming has greatly promoted the development of tourism. The original site of the exposition has been preserved and is still open to the audience as an important tourist attraction. Coupled with Yunnan's rich tourism resources, such as Shilin, Dali, Lijiang, Xishuangbanna and Shangri-La, Yunnan has become a tourist hotspot for domestic and foreign tourists. In addition, like the Olympic Games, when hosting the World Expo, major companies and enterprises all over the world have invested a lot of money in advertising, which is not only conducive to the development of the advertising industry, but also has become an important source of funds for the World Expo.
The World Expo is a place for education, dissemination, popularization and publicity of scientific, technical and cultural knowledge.
The World Expo is a large-scale exchange activity of international economy, science and technology, culture and art. Participating countries display their latest scientific and technological inventions, which plays a positive role in spreading, popularizing and publicizing scientific and technological knowledge. In order to attract tourists and improve the interest of viewing, the participating countries adopted the art or modern technology such as "sound, light and electricity" to create a special atmosphere, which is vivid and lifelike. The exhibits are popular and artistic, and the high-tech content is sent to general simple exhibition activities to publicize scientific and technological knowledge. 1985 After the Tsukuba Science and Technology Expo in Japan, it was transformed into a national science and technology city in Japan and became a research center in Japan. Many large enterprises and companies have high-tech R&D institutions here. After the Daejeon World Expo 1993, the original site was converted into a science museum for young people from all over Korea to visit and study. In 2000, the Hanover World Expo opened a theme park to show people's understanding of the future with vivid scenes. Many children play with robots in the "park" or enter the future world to experience the life of other planets. There is an information superhighway system in the China Pavilion. Visitors, especially teenagers, drive into the information superhighway by computer to learn about China's politics, economy, military, society and culture. There were a sea of people during the exhibition, and the effect was good.
