Green Inventions: Is Wait-and-see a Reasonable Option?
研究分析了不同知识储备对缩小绿色技术发明领先者与追随者之间技术差距的作用，发现观望策略难以保持竞争力，外部绿色知识效果有限，非绿色知识反而扩大差距。
We analyze the potential of different knowledge stocks to decrease the technological gap between the leader in green technology inventions and its followers in order to identify if wait-and-see is a reasonable option to benefit from knowledge. Our econometric results indicate that it is difficult to decrease the technological gap and remain competitive in the generation of green technologies without timely accumulating green knowledge. Although effects from external green knowledge stocks also contribute to decrease the technological gap, the effects are moderate and they cannot compensate the lack of internal green competences. Non-green knowledge stocks even tend to increase the technological gap.
