"The number of inbound tourists refers to the number of foreign tourists or non-local residents traveling to a certain country or region. The number of inbound tourists is an important indicator of the tourism industry, which can reflect the tourism attractiveness and development level of a country or region.

Statistics on the number of inbound tourists are usually carried out by the governments or tourism departments of countries and regions, and surveys and data collection are carried out through various means such as border inspections and tourist questionnaires. In some countries and regions, the number of inbound tourists is divided into short-term tourism and long-term tourism in order to better evaluate the contribution and potential of the tourism industry.

The increase in the number of inbound tourists can bring a series of economic and social benefits, including increasing domestic consumption and employment opportunities, improving the level of local economic development, promoting cultural exchanges and mutual understanding, etc. At the same time, changes in the number of inbound tourists will also affect tourism-related industries, such as aviation, hotels, catering, and retail.

However, the increase in the number of inbound tourists will also bring about some negative impacts, such as environmental pollution, cultural conflicts, and potential safety hazards. Therefore, the government and the tourism industry need to take measures, such as strengthening environmental protection, cultural promotion and safety precautions, to ensure the sustainable development of tourism.

In short, the number of inbound tourists is one of the important indicators of tourism development and international exchanges, and plays an important role in evaluating the economic and cultural influence of a country or region. "
