价值链分工背景下,准确衡量贸易利益及其影响因素已经成为国际贸易经济中的一个重要话题。借鉴Koopman(库普曼)等人提出的分析框架,结合欧盟WIOD数据库中的世界投入产出表(WIOTs),测算了39个经济体1995年~2011年出口总值中的贸易增加值,并以此作为贸易利益代理变量进行大样本跨国面板数据实证检验,考察各因素的影响作用。结果表明:一国在贸易中所获得的利益取决于分工形式、要素禀赋差距、研发强度、加权关税率以及基础设施等一系列制度性与非制度性因素。
In the context of value chain division of labor, accurately measuring trade interests and their influencing factors has become an important topic in the international trade economy. Using the analytical framework proposed by Koopman et al. And the WIOTs in the EU WIOD database, the added value of trade in the total export value of 39 economies from 1995 to 2011 was estimated. As a proxy for trade interests, a large sample of cross-border panel data empirical test to examine the impact of various factors. The results show that the benefits obtained by a country in trade depend on a series of institutional and non-institutional factors such as the form of division of labor, the factor endowment gap, the intensity of research and development, the weighted tariff rate and infrastructure.
