| In recent years,China is seeking the economic growth pattern that is more sustainable,inclusive and resilient.As the sole major economy achieving positive economic growth across the world since 2020,China is undertaking the great country’s responsibility of leading global economy to achieve “green recovery”.With the timely proposal of the "double carbon" goal,energy conservation and carbon reduction will be incorporated into the national economic and social development plan.Under the development goal of "Made in China 2025" emphasizing the optimization of industrial energy structure through Internet information technology,how to reduce carbon emissions,improve energy efficiency and promote green economic transformation and development with the help of digital economy has become the development trend in the future.Then,how does the digital economy play a role in improving energy efficiency,and what about its carriers and forms? Whether the strong penetration of digital economy will enhance the transformation of energy efficiency achievements through the intermediary of market trade through the integration with the real economy sector.Further analysis,whether there is a big gap between the spillovers obtained by participating in the domestic market and the international market will be the focus of this paper.At this background,the thesis calculates 30 provincial energy efficiency in total factor from 2011 to2018 in China,with combining data of digital economy in different provinces and employing to examine the impact of provincial digital economy on total factor energy efficiency.On the basis of that,GMM is adopted to verify the path of digital economy affecting energy efficiency through intermediary effect.According to the empirical conclusion,the author finds that: on the whole,the digital economy plays the significantly positive role in the improvement of regional total factor of energy efficiency;meanwhile,the mesomeric effect could be found between them.Furthermore,domestic and abroad market trade serve as the important pathway.What’s more,from the geographical perspective,the role of the digital economy in promoting energy efficiency is gradually decreasing from east to west.After researching the geographical conditions in eight economic zones,the author discovers that the digital economy has an even stronger impact on energy efficiency in eastern and southern coastal area,the Yellow River,the middle reach of the Yangtze River as well as the northwestern economic zone.The transformation of energy efficiency made by digital economy varies in different regions.Therefore,it is necessary to take development methods in accordance with different current situations to boost the digital economy and improve energy efficiency.Hence,suggestions are as follows: the government need to promote the development if digital trade,unleash the domestic market demands,strengthen the overflow and gnawing-away effect of trade in energy efficiency.The government should give helps for the green development of low-energy-efficiency provinces in an active manner,push the deep integration and balanced development between digital economy across regions and energy industries. |
