Abstract: This paper analyzed the demand elasticity of substitution of wind power electricity to traditional power electricity,by constructing the social electricity demand function.To internalize the negative externalities that the traditional power electricity brings to the society,the government could raise the price of traditional electricity through certain policy instruments.The social demand for wind power would therefore significantly increase through the substitution effect.Driven by increasing demand,the wind power industry would achieve rapid growth.Our computation results showed that,taken the year of 2009 as an example,by increased 0.01 yuan in the price of traditional power electricity,the demand of wind power electricity in the whole could be raised by 103 million kilowatts at most.Therefore,the government could try to use policy instruments such as carbon tax or pollution quotas to increase the price of traditional power electricity,increase the society's total demand for wind power,promote wind power industrial progress,and optimize the social welfare.
