Analyze and discuss the demand elasticity of tourism.

A: The price elasticity coefficient of tourism demand mainly refers to the ratio of the percentage change of tourism product price to the percentage change of tourism demand. It can usually reflect the degree to which tourism demand changes with the price of tourism products. Because the price of tourism products is inversely proportional to tourism demand, the price elasticity coefficient of tourism demand is negative. According to the absolute value of the price elasticity coefficient of tourism demand, it can usually be divided into three situations:

(1) When | EDP | > 1, the price of tourism demand is elastic. The slope on the demand curve is large, indicating that the percentage of tourism demand change is usually greater than the percentage of tourism product price change. In practice, it shows that the price of tourism products will increase and the demand for tourism products will decrease, but the percentage of decrease is greater than the percentage of price increase, which will relatively reduce tourism income; On the contrary, if the price of tourism products drops, the tourism demand will increase, but the percentage of increase is greater than the percentage of price drop, which will make the tourism income increase relatively.

(2) When | EDP | < 1, the elasticity of tourism demand is insufficient. The slope on the demand curve is small, indicating that the percentage of tourism demand change is generally less than the percentage of tourism product price change. In practice, it shows that if the price of tourism products increases, the tourism demand will decrease, but the percentage of decrease is less than the percentage of price increase, which will lead to a slight relative increase in tourism income; On the contrary, if the price of tourism products drops, the tourism demand will increase, but the percentage of increase is less than the percentage of price drop, which will slightly reduce the tourism income. It shows that the price change of tourism products has little effect on the increase of tourists and the decrease of income.

(3) When |Edp|= 1, the price elasticity of tourism demand is unit elasticity. It shows that the percentage change of tourism demand is equal to the percentage change of tourism product price, so the influence of tourism product price change on the increase of tourists and the relative decrease of income changes year-on-year, and will not affect the total income of tourism operators.
