“…As described in Table 1, After matching the product-level trade data and firm-level production data, the remaining observations account for nearly 15 percent of the original firm-level production dataset yearly, and about 25 percent of the original product-level trade dataset, and more than half in terms of export value. By way of comparison, our matching success rate is highly comparable to that in other studies that use the same datasets, such as Wang and Yu (2012), Ge et al (2011) andYu (2014). In the baseline estimation, we only use matched firms appearing each year, that is exporting every year (around 5,404 firms), but the results are not significantly changed after including the incidental exporters, which is done in our robustness check.…”
