基于广义 Bass 模型,对比中国与世界其他风能先进国家在技术创新水平和模仿水平上的差异,考察外生政策冲击对中国风能技术扩散的影响。利用常规 Bass 模型、广义 Bass模型、Logistic 模型和 Gompertz 模型等多个预测模型对中国未来风能技术的扩散趋势进行短期预测,并对其预测精度和结果差异进行对比和分析。研究结果表明,中国风能技术市场的创新水平显著低于其他风能技术较为先进的欧美国家,甚至低于同为发展中国家的印度,模仿水平在所有考察国家中最高;中国风能技术扩散过程受指数冲击和矩形冲击的影响,但两种外部冲击的影响程度均较弱;中国风能技术急速增长的阶段已经过去,且于2010年达到增长的阶段性峰值点,未来的增速将显著放缓。针对上述结论给出促进中国风能长效发展的相关政策建议。
基于廣義 Bass 模型,對比中國與世界其他風能先進國傢在技術創新水平和模倣水平上的差異,攷察外生政策遲擊對中國風能技術擴散的影響。利用常規 Bass 模型、廣義 Bass模型、Logistic 模型和 Gompertz 模型等多箇預測模型對中國未來風能技術的擴散趨勢進行短期預測,併對其預測精度和結果差異進行對比和分析。研究結果錶明,中國風能技術市場的創新水平顯著低于其他風能技術較為先進的歐美國傢,甚至低于同為髮展中國傢的印度,模倣水平在所有攷察國傢中最高;中國風能技術擴散過程受指數遲擊和矩形遲擊的影響,但兩種外部遲擊的影響程度均較弱;中國風能技術急速增長的階段已經過去,且于2010年達到增長的階段性峰值點,未來的增速將顯著放緩。針對上述結論給齣促進中國風能長效髮展的相關政策建議。

This paper investigates the differences of innovation and imitation in wind technology between China and some other countries with leading wind technology based on Generalized Bass models , and explores the impacts of exogenous policy interven-tion on China′s wind technology diffusion .Short-term forecasts and prediction accuracy of the China′s wind technology in the fu-ture are provided and contrasted by performing Standard Bass model , general Bass model , Logistic model and Gompertz model . We find that:the level of wind technology innovation of China is significantly lower compared to the wind -advanced American and European countries and some developing countries such as India , while the imitation level is significantly higher than all sampled countries, both exponential shock and rectangular shock are found to have a limited and weak effect in the development of wind technology diffusion, rapid development process of wind is over with the peak occurred in 2010, and the wind adoption process is in its middle stage and the speed of technology diffusion is predicted to slow down in the future .Based on the conclusions , we fi-nally propose some policy suggestions for the sustainable development of wind technology .
