摘　　要：This paper introduces a quasi-natural experimental framework into trade policy evaluation and reassesses China s trade liberalization through the survival of export products.We use propensity score matching and China s dual trade system to design a quasi-natural experiment based on Chinese industrial enterprises,customs import and export,and tariff data over the period of 2000-2006;we then use survival analysis to study the impacts of China s trade liberalization on the export duration of manufacturing firms9 products.We find that the substantial reduction in import tariffs after China s accession to the World Trade Organization enhances the export duration of firm products,indicating that trade liberalization ameliorates the survival of export products.The promotion effects of tariff reduction on export duration are obviously stronger for core products than for noncore products.
