CORRELATION MEASUREMENT AND EFFECTS OF CHINA'S NEW ENERGY INDUSTRIES
Energy consumption transformation is necessary in the new developing era.Energy structure transformation based on new energy is an important part in China's modernization.This paper,in order to study the impact of China's new energy industries on economy,compiles new energy economy input/output tables of 2015,2017,2018 and 2020.To further analyze the inner connection within new energy industries,this paper uses structural decomposition to estimate endogenous multiplier effect,drawback effect and spillover effect of new energy industries.New energy industrial scale has been increasing,with its added value rate at a high level but its impact less than the average,not strong enough to boost economy.New energy industrial sectors have no strong inner correlation,but they have post-direct correlation with all industrial sectors,including manufacturing and construction under indirect depletion.Static decomposition shows that endogenous multiplier effect,drawback effect and spillover effect of new energy industries are all below the average,among which spillover effect is the major source of its increasing output,but falling in 2020,roughly equal to endogenous multiplier effect's contribution.The further dynamic decomposition suggests that the major source of increased outputs is stimulated by other sectors'final demand to its sectors'final demand and to other new sectors'final demand.Generally,new energy industries have a rising correlation with other industries.New energy industries are at an upgrading stage.This paper presents suggestions on boosting research and development to intensify its leading role in economy,planning its industrial cluster and linking with such industries as manufacturing and construction,giving supportive policies to increase its sensing capacity.
