This paper examines whether exporting activity contributes to the promotion of creative destruction and the upgrading of a plant's product portfolio. We first present evidence that exporters tend to produce, on average, products with higher attributes than non‐exporters. Next, we find evidence that exporting improves a plant's average product attributes, utilizing the propensity score difference‐in‐difference matching technique. Further examination of the mechanism reveals that the positive effect of exporting on a plant's average product attributes is more likely to be realized through its effect of adding higher‐attribute products, a key feature of creative destruction within a firm, rather than through share changes among continuously produced products. The results suggest that exporting might have contributed to the sustained economic growth of Japan and Korea by promoting creative destruction

日本和韩国的出口对创意破坏和植物平均产品特性的影响

本文研究了出口活动是否有助于促进创造性破坏和工厂产品组合的升级。我们首先提出的证据表明，出口商平均而言会生产比非出口商更高属性的产品。接下来，我们发现证据表明，利用倾向得分差异差异匹配技术，出口可以改善植物的平均产品属性。对该机制的进一步研究表明，出口对工厂平均产品属性的积极影响更可能是通过添加较高属性的产品（公司内部创造性破坏的关键特征）的效果而不是通过份额变化来实现的。连续生产的产品。
