Decomposing the Within-Firm Productivity Gains from Trade: Evidence from India
提出一种分解企业层面收入全要素生产率增长的方法，并利用印度制造业数据估计中国进口竞争和投入品获取增加带来的生产率收益，发现企业会通过质量升级和产品调整来应对竞争。
Abstract We develop a decomposition of firm-level revenue-based TFP growth into six margins: i) mean quantity-based TFP growth, ii) mean growth in demand shifters, iii) intensive margin specialization effects, iv) scope effects, v) product adding effects, and vi) product dropping effects. We then estimate and decompose firm-level revenue-based TFP gains generated by increased Chinese import competition and input access using Indian manufacturing data. We find evidence of quality upgrading in response to increased output market competition, and that firms tend to add new products that are lower productivity than their incumbent goods in response to increased input access.
