全球价值链影响下的中国关税水平*——来自中国制造业的证据
THE CHINESE TARIFF LEVEL UNDER INFL UENCE OF GLOBAL VALUE CHAIN——Evidence on Chinese Manufacturing Industry

摘要 本文基于中国政治经济背景，构建了一个关税影响因素理论模型，且利用2005—2011年中国制造业134个部门的数据，通过OLS和Tobit方法进行了经验验证。结果表明：（1）外国最终产品中的中国增加值越高，或者中国最终产品中的外国增加值越高，则中国对于该产品的关税水平越低；（2）贸易协定的签署不仅会直接降低中国的关税，还会扩大中国增加值上升对关税的负影响，削弱外国增加值上升对关税的负影响。
