Provincial Differences in the Development of Energy Storage Technology in China and Its Influencing Factors:Taking the Energy Storage Patents of the Top Five Provinces in Terms of National Installed Capacity as an Example
The foundation of economic development and scientific and technological development in our regions varies greatly.In order to explore the relevant factors affecting the development of energy storage technology,taking five provinces with the largest installed capacity of energy storage in China,namely Shandong,Ningxia,Guangdong,Hunan and Inner Mongolia as the research objects,the number of their energy storage invention patents from 2001 to 2021 is used as the explained variable,the regression equations are constructed for the quantitative analysis.The results show that the number of energy storage invention patents promoted by R&D expenditure has increased rapidly,and the amount of energy storage invention patents,technology market transaction volume,R&D investment and wind power and photovoltaic power generation have initially formed a virtuous circle of mutual promotion;the number of energy storage invention patents of five provinces has increased rapidly since 2010,especially in Guangdong and Shandong,where the economic aggregate is at the forefront of the country,have transformed from R&D demonstration to the initial stage of commercialization.According to the influence degree of each variable,the development of energy storage technology in Guangdong and Hunan can be divided into science and technology promotion type,Shandong belongs to science and technology exchange promotion type,while Inner Mongolia and Ningxia belong to power output promotion type.Based on the research,it is proposed that different regions should take targeted measures to promote the development of energy storage technology based on their own actual conditions,and at the same time,all provinces should strengthen cooperation and establish a cross-regional technology trading market.
