This study examines the impact of firm internationalization on incremental and radical product innovation, and the effects of these innovation facets on sales growth. We use a sample of 1,064 Spanish manufacturers over the period 2008–2014. We find a positive relationship between higher international scope and greater ex-post radical innovation output, and an inverted U-shape relationship between export intensity and both innovation forms. We also find a positive relationship between incremental innovation and sales growth for performance leaders, and negative for performance laggards. Conversely, radical innovation boosts performance laggards' sales growth, but reduces that of performance leaders. The study supports and qualifies the learning-by-exporting effect, by identifying some firm-specific factors that shape the relationship between internationalization, innovation, and firm performance.

理清国际化、渐进式和激进式创新与公司绩效之间的关系

本研究考察了企业国际化对渐进式和激进式产品创新的影响，以及这些创新方面对销售增长的影响。我们使用了 2008-2014 年期间 1,064 家西班牙制造商的样本。我们发现更高的国际范围与更大的事后激进创新产出之间存在正相关关系，出口强度与两种创新形式之间存在倒U型关系。我们还发现，对于绩效领先者而言，增量创新与销售增长之间存在正相关关系，而对于绩效落后者而言则是负相关。相反，激进创新促进了绩效落后者的销售增长，但降低了绩效领先者的销售增长。该研究支持并限定了通过输出学习的效果，
