Does patenting help or hinder open innovation? Evidence from new entrants in the solar industry
研究了太阳能行业新进入者的专利存量如何影响其后续开放式创新关系数量，发现专利化总体上增加关系数量，但效果因技术强度而异：高技术强度关系正向效应强，低技术强度关系则转为负向。
This article analyzes how the patent stock of new entrants in industries shaped by systemic innovations influences their subsequent openness in innovation. The results suggest that patenting increases new entrants’ number of open innovation relationships, on average. This association, however, varies across relationships of differing technology intensity. While the effect of patenting is strongly positive for technology-intensive relationships, it becomes weaker as the technology intensity decreases, and turns negative for least technology-intensive relationships.
