To be sure, because tariffs in the TPP member countries are already low (with some exceptions, such as Canada’s tariffs on dairy products and Japan’s on beef), the net benefit of eliminating them would be modest (except for a few items that are very sensitive to small price changes). But the TPP is also expected to reduce non-tariff barriers (such as red tape and protection of state enterprises); harmonize policies and procedures; and include dispute-settlement mechanisms.
如今，几乎世界所有地区的增长都无法达到预期，因此TPP似乎是值得欢迎的措施。诚然，TPP成员国的关税水平已经相当低（但也有一些例外，如加拿大的乳制品关税和日本的牛肉关税），取消关税的净收益将十分有限（除了少数对微小价格变动也十分敏感的商品）。但TPP还能减少非关税壁垒（如官样文章和对国企的保护）、协调政策和程序，并包括了纠纷解决机制。
