What is tourism trade deficit?

The "tourism service trade deficit" refers to the inbound and outbound tourism balance of mainland my country or mainland China. Since 2009, my country's mainland or mainland tourism foreign exchange receipts and expenditures have turned from a long-term surplus to a deficit, indicating that the total income from inbound tourism is lower than the total expenditure from outbound tourism. Since my country's inbound and outbound tourism is divided into two parts: the foreign market and the Hong Kong, Macao and Taiwan market, Hong Kong, Macao and Taiwan are also included in the inbound and outbound tourism revenue and expenditure statistics, so the conclusion of "tourism service trade deficit" is drawn.
