The significance of clean energy development for China’s energy security from 2010 to 2019

Abstract

Energy security is a matter of economic security and national security. This paper examines the influencing mechanism of clean energy on China's energy security from 2010 to 2019, by using the entropy method and spatial econometric model. The results show that (1) from 2010 to 2019, China's energy security index shows an overall decreasing trend. The western region has the highest energy security index, followed by the central, northeastern, and eastern regions; (2) there is an inverted u-shaped relationship between clean energy and energy security; (3) in the short term, clean energy will have a negative effect on industrial structure upgrading. But with the expansion of its scale, clean energy development will promote the industrial structure upgrading, and then improve energy security; and (4) the development of clean energy has a positive effect on the adjustment of energy structure.
