China's technological efforts to tackle climate change have lasted for many years.It is necessary to test the effect of these efforts with quantitative method.To be exact,whether and how China's low-carbon technology innovation responds to climate change should be tested.Based on the panel data of 30 provinces from 2004 to 2015 in China,we use the method of ESDA to analyze the spatial correlation of China's low-carbon innovation technology.Furthermore,we use the SDM model empirically analyzing the spatial spillover effect.The results show that:①Supply and demand of Chinese low-carbon innovation has some deviation in the spatial distribution.The low-carbon technology innovation as the supply factor shows the characteristics of expanding from the east to the west.Innovation in eastern China has always been the most active,but innovative activities in the middle and western China are gradually decreased.While carbon emissions have the characteristics ofmoving westward',implying the change of technology demand different from technology supply.②China's low-carbon innovation actively responds to the trend of climate change,indicating that China's technological efforts have paid off.However,the spatial spillover effect is not significant,showing that the efforts in each region of China still work for itself.③Environmental regulation and pulling effect of market are important factors for low-carbon technology innovation.Among them,both supporting policy and inhibitory policy have significant impacts on the local low-carbon technology innovation,but no significant spatial spillover effect.It shows that environmental policies in different regions are competitive and lack of demonstration effects.Economic growth and export as the pulling effect of market have higher level of effects on low-carbon technology innovation for both local and adjacent areas.Some policy implications include:Firstly,regional coordinated development is necessary in China,resources should reasonably flow from eastern to middle and western China.Secondly,local governments should take advantage of environmental regulation and improve combination of different policies.Thirdly,China should exert the role of both domestic and international markets,and extend and upgrade the green industry chain.
