Summary/Abstract

This study examines whether exporters become more productive through estimating a production function using Chinese firm-level data from 1997 to 2000. The results indicate that exporters are more productive and, more importantly, that export strategies promote the productivity of these firms. The test for the relative timing of export behaviour and gains in productivity provides strong evidence for the existence of learning-by-exporting effects rather than self-selection effects. These results are robust when controlling simultaneous bias and selection bias by using a fixed-effects model, SYS-GMM estimation and semi-parametric estimation.

Summary/Abstract

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 firms’ 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.
