The economic impact of tariffs imposed by small countries mainly includes:

1, and tariffs increase the economic operating costs of the taxing country;

2. If tariffs are imposed on scarce luxury goods and resources, it is equivalent to consumption tax;

3. If tariffs are imposed on national necessities, it will change the expenditure structure of residents' consumption, increase the proportion of basic living expenses, reduce the consumption of goods and services used in the new economy and new industries, and shrink the cake of innovative enterprises;

4. If tariffs are imposed on the upstream products necessary for the production of enterprises, traditional industries can still bear a burden in the short term. The new economy start-ups need to use the good and cheap goods provided by global suppliers at low cost, but now their costs have increased, their expenses have increased, and the risk of innovation and entrepreneurship has greatly increased.
