1. Why is regional tourism a hot spot of world tourism? And give an example analysis. 2. Why do local governments in China attach importance to the development of convention and exhibition industry?

1. Any country is composed of core area and peripheral area. In the process of regional economic growth, there is an unequal development relationship between the core area and the marginal area < P >, with the core area playing a leading role and the marginal area depending on the core area in its development.

the spatial pattern of tourist cities in Sichuan province presents a typical core-edge structure. Chengdu, the capital city in the central location, has always been the largest tourist city in Sichuan Province, as well as the distribution center and destination for domestic and foreign tourists to travel to Sichuan [19], which has formed a high priority and is the core area of tourism development in Sichuan Province, while other cities form marginal areas. The fringe area depends heavily on the development of the core area, and tourism investment, transportation, construction of basic tourism service facilities and domestic and foreign tourists flow are mainly concentrated in the core area.

2. Although the development time of China's convention and exhibition industry is very short, it has attracted more and more attention of major cities in China because of its huge economic benefits and social functions, and has developed rapidly in China. Economic globalization makes capital, information, resources, talents, technology and other factors of production flow freely and optimize their allocation around the world. China's superior geographical location and China's powerful radiation function to the economic development of surrounding areas will make China an ideal hot spot to attract investment from multinational exhibition groups. The entry of foreign capital can bring us mature foreign exhibition ideas, rich exhibition experience, advanced exhibition technology and well-known exhibition brands, and promote the internationalization, specialization and collectivization of China's exhibition industry, which will give us a historical opportunity to catch up with developed countries in exhibition by using foreign capital brand project management technology, and China can become a world-class exhibition country and exhibition power in East Asia.
