The Analysis and Comparison of the Comprehensive Index of the Development of China Urban Exhibition Industry

With the development of modern economy, exhibition industry has become an important platform for the construction of modern market system and open economic system. At present, there are many indicators to measure the competitiveness of urban exhibition industry in China. The annual index of competitiveness of Chinese city exhibition industry initiated by China convention and exhibition economic association has become the most authoritative report of competitiveness index of city exhibition industry. The exhibition industry is also one of the important evaluation criteria. This paper mainly uses the above two methods to calculate the exhibition competitiveness index of Chinese cities, and introduces the correlation coefficient to compare the stability of the ranking of the exhibition competitiveness index by the two methods. The study found that the correlation coefficient between the cities at the top and bottom of the ranking was large, that is, the ranking was relatively stable and barely changed. However, the ranking correlation coefficient of cities in the middle is smaller and the change is significant. However, the correlation coefficients of the cities ranked 21-40 are less than those of the top 20 cities, which also indicates that the abrupt change in the ranking of individual cities will affect the overall stability. Because of this, it shows that the evaluation indexes under different weights have a certain influence on the calculation of the comprehensive index of the city’s exhibition competitiveness, and the AHP method can better reflect the advantages and disadvantages of the city’s exhibition industry development.
