Research on the Development Characteristics and Prediction Models of American Outdoor Leisure Industry——Analysis Based on PLS and PLS-DA Methods
Outdoor recreation is a pillar industry of the American economy.Analyzing its development characteristics and con-structing prediction models will have important reference value for the healthy and sustainable development of China's fitness and leisure industry.We collected data on the outdoor leisure industry in the 50 states of the United States in 2021,selected 27 impact indicators,and used the PLS and PLS-DA methods to analyze the development characteristics of the outdoor recrea-tion in the United States and build predictive models.Studies show that:(1)The U.S.state outdoor recreation can be divid-ed into 4 development modes,namely,high total amount,low proportion;low total amount,high proportion;total amount rel-atively high,proportion relatively low;total amount relatively low,proportion relatively high.The four development models present certain spatial distribution characteristics.(2)The prediction model is effective and highly accurate,and 12 VIP indi-cators are screened out;economic,demographic,and social factors seem to affect the development of outdoor recreation in the United States more,but the impact of natural environmental factors is relatively weak.
