As countries implement tariff protection of trade policy measures, since
countries one of import and export commodity structure, the focus of the
different different protection, leading to even the same tariff levels in
different countries production and market of domestic protection is not
the same. Therefore, we need to have a comprehensive assessment tariff
protection degree of index system. Usually use tariff BaoHuLv name,
effective BaoHuLv and tariff structure indexes, such as the comprehensive
measure to protect the size of one country tariff level.
1. Tariff levels
Tariff levels (tariff level) is to point to a national average of import
tax rate with tariff. Can be roughly measure is a national import duties
or the degree of protection, it is also a country attend trade agreement
negotiations customs problems must be solved. For example, in gatt
negotiations, tariff cuts will often tariff levels as more countries
tariffs and cut tariffs on the index. Tariff calculation, can through the
two methods of calculating the average gain simple method and weighted
average method.
Simple average method according to the tax rate is one country tariffs
(legal rate) to calculate, namely whether every tax items of the actual
import quantity, according to the number of tax items only tariffs for
its rate of the arithmetic mean because many of tariffs. High tax rates
of the taxes is prohibitive tariffs, little or no relevant goods import,
and some of the import a lot of goods is zero tax or tax-free. Therefore,
the calculation method of the important tax items will trade and the
secondary tax items are in the same weight calculation, is clearly
unreasonable. Because simple average method can't truthfully report the
one country tariff levels, so is seldom used.
The weighted average method is to use the number of imported goods or
prices as a weighted function to average. According to statistics caliber
or more range of different, can divide again for a full of the weighted
average method and the sample of the weighted average method two kinds.
(1) the sum of the weighted average method, that is, according to a
period of import duties on the total amount of all imports value. A
percentage of the total value of formulas for the
Tariff levels = x 100%
In this calculation method, if one country in tariffs exempt items, more
calculated value is low, hard to see some tax rate. So the discretion of
the goods, the other a kind of method is according to import tax has the
percentage of their gross commodities import tax calculation, this
