Effects of Tourism

Tourism is becoming an increasingly important industry in China. Our government has taken ef fective measures to improve this new industry over the past few years. For example, it has explored many appealing scenic and historic spots. Tourists from all over the world come in flock to China every year.
But people differ as to the advantages and disadvantages of the tourist industry. Those who are in favour of tourism argue that our country can benefit a lot from it. For one thing, it is a large source of foreign exchange and an important part of national planning as well. For another, we may well say that tourism can help to promote the understanding and friendship among the peoples of different countries.
The main reason why some people oppose tourism is that the masses cannot benefit from it because the pressure of too many tourists means the higher prices of goods.

In spite of this, I think its gains outweigh its losses. It also means more employment and more income for the country. For this reason the tourist industry should be developed vigorously so as to meet the needs of our socialist economy.
