Measurement of coordination level and identification of influencing factors among exhibition industry, transportation industry, and tourism industry based on coupled coordination obstacle degree model

The exhibition industry has strong interdependence and mutual promotion with the transportation and tourism industries. Studying the coordination level of exhibition-transportation-tourism and exploring the factors that affect coordination is an important topic. Wuhan has abundant tourism resources and is a hub for nine provinces, but exhibition level is not high. It is necessary to accurately determine the influencing factors of the coordination among exhibition,tourism,and transportation, so that Wuhan's good transportation conditions and tourism resources can provide support for the development of the exhibition industry. This article takes Wuhan as the research object, constructs a comprehensive evaluation index system for the exhibition-transportation-tourism in Wuhan and collects receipts. By using entropy method, comprehensive evaluation model, coupling degree, and coupling coordination degree model, the comprehensive development level and coupling coordination level of the three industries from 2013 to 2022 are calculated and analyzed, and the main obstacle factors are calculated through the obstacle degree model. The research conclusion is as follows. Firstly, the coupling degree between the exhibition industry, transportation industry, and tourism industry in Wuhan is extremely high, and the coupling coordination degree shows a fluctuating upward trend, indicating an unstable coupling coordination situation. Second, the COVID-19 in 2020 has a great impact on Wuhan's exhibition industry, transportation industry and tourism industry, and the economic benefits will be affected. The third is that the level of influence of exhibitions, transportation capacity, and tourism scale are the key obstacles. Based on these three obstacles and the background of the big data era, countermeasures are got to jointly improve the high-quality integrated growth of the three.
