The interplay between product innovation, publishing, patenting and developing standards
研究了企业发表论文、申请专利和参与标准制定这三种知识披露行为在产品创新中的关系，发现发表与专利、专利与标准制定是替代关系，而发表与标准制定无显著关联。
Firms use a variety of practices to disclose the knowledge generated by their R&D activities, including, but not limited to, publishing findings in scientific journals, patenting new technologies, and contributing to developing standards. While the individual effects of engaging in the listed practices on firm innovation are well-understood, the existing literature has not considered their interrelation. Therefore, our study examines if the three practices are complements, substitutes, or unrelated in terms of firms’ performance with product innovations new to the market. Our analysis builds on a sample of innovation-active firms from the German Community Innovation Survey, which includes information on the development of standards, enhanced with information on firms' engagement in patenting and publishing. We find that 26% of innovation-active firms engage in at least one of the three practices, and 22% of engaging firms combine them. Using supermodularity tests, we show that publishing and patenting as well as patenting and developing standards are substitutes. Publishing and developing standards are not significantly linked. Based on our findings, we derive implications for innovation management and policy.
