摘    要:本文利用WIOD的宏观投入产出数据和大样本微观企业合并数据, 采用两步系统动态GMM估计方法分析融入产品内国际分工体系对我国企业出口二元边际的影响.研究结果发现, 融入全球产品内分工体系显著促进企业集约边际的增长, 但没有促进扩展边际的增长; 融入全球产品内分工体系促进加工贸易企业及港澳台、 外资企业集约边际的扩张, 抑制国有和集体企业扩展边际的增长.

关 键 词:产品内分工  扩展边际  集约边际  加工贸易

Abstract:With the input-output database of WIOD and the large sample micro firms'merging data, by using GMM two-step system dynamic estimation method, this paper studies how the embeddedness of intra-product specification affects the dual margins of firms'export.The main conclusions are as follows: the embeddedness has a positive influence on firms'intensive margins, but no significant influence on extensive margins; the influences on dual margins differ among different ownership and trade patterns;the embeddedness stimulates the expansion of intensive margins of processing trade as well as HMT and foreign firms, while it restrains the extensive margins of state-owned or collective firms.The research has practical reference value for the transformation of China's export-oriented development strategy.
Keywords:intra-product specification  intensive margins  extensive margins  processing trade
