引入扩散系数改进David Pop知识存量测度模型，使其更适用于绿色技术专利存量测度；以OECD国家绿色技术专利为数据源，实证分析了绿色技术专利存量的经济吸引力；建立绿色技术存量与经济增长关系模型，基于固定效应模型分析了绿色技术知识存量对经济的作用。结果显示，绿色技术与经济增长呈“U”型曲线，在绿色技术发展初期有阻碍经济增长的作用，这种负向作用随着创新数量的增多逐渐降低。随着时间的推移，绿色技术对经济增长具有促进作用，但促进效果逐渐减弱；将 OECD作为一个整体，可以看到绿色技术专利数量与经济发展水平具有门槛值，当绿色技术专利存量达到转折点（1250个绿色专利存量），开始对经济增长具有显著的促进作用。但大多数 OECD成员国距离这个转折点仍然遥远，尽管各国每年绿色技术专利数量呈增长趋势，但其负向作用尚未达到谷底，这些国家进行绿色技术创新还无利可图。

An improved calculation model was built by the introduction of diffusion coefficient based on the one proposed by David Pop ,w hich makes it more suitable for the green technology patent stock measurement .Furthermore ,the economic competitive analysis of green technology stock is also conducted by using OECD countries data .In general ,this paper built a measurement model of green technology patent stock ,and calculated the green technology patents stock of OECD coun‐tries ,obtained the relationship between green technology stock and economic growth ,and analyzed the effect of green tech‐nology knowledge stock on the economy based on the fixed effect model .Regarding the OECD organization as a whole sam‐ple ,the green technology innovation will come to a turning point (1 250 green patent stock) ,but most OECD countries are still far away from this turning point ,although the annual number of green technology patents mostly are increasing which is outweighed by the negative effects not yet reaching the bottom level .The green technology innovation of these countries is not yet profitable ,but the cost is huge .
