Analysis of the Influence of the Asian Games Based on Decision Tree Model

Under the background of globalization of sports events and diversification of urban development, the Asian Games, as the highest level comprehensive sports event in Asia, has increasingly become the focus of academic attention in terms of its economic, social and cultural influence. Taking the recent ten Asian Games as the object, this study aims to quantitatively evaluate the impact of the games on the host city in the dimensions of economic growth, infrastructure upgrading, tourism driving and cultural transmission through cluster analysis and SVM model. The study uses multi index panel data, combined with case comparison and econometric analysis, to reveal the temporal and spatial differences and key driving factors of the influence of the Asian Games. The results show that the Asian Games can significantly promote the GDP growth of the host city in the short term and enhance the international attention, but the long-term benefits are significantly affected by the city size, industrial structure and the efficiency of event resource allocation; Infrastructure investment and cultural heritage activation are the core paths to form sustainable influence. Research suggestions: build a collaborative planning mechanism of "event economy urban development", strengthen the market-oriented design of venue operation after the games, and promote the deep integration of sports events and cultural tourism industry, so as to maximize the long-term positive effect of the Asian Games.
