Research On The Impact Of Human Capital And Scientific Research Input On Provincial Carbon Emissions Based On Spatial Econometrics

In 2007,China has overtaken the United States as the world's biggest carbon emitter.Since then,China's air pollution has reached a critical state and has attracted extensive attention from the international community.In order to solve this problem,a target of carbon dioxide emissions to be peak around 2030 was proposed by China in 2015.As an important impact of technological innovation,the human capital input and the scientific research investment become the primary driving force for development of low-carbon.In view of this,the impact of human capital input and scientific input on China's carbon emissions has been studied in this paper,which has great theoretical value and important guidance in pursuit of sustainable development.Based on the panel data of China's 30 provinces(Except Tibet,Hong Kong,Macau and Taiwan)from 2007 to 2016,the paper measures the carbon emissions of these regions making use of the carbon emission coefficient of energy sources provided by IPCC,and applies the entropy method to measure human capital and scientific research investment.Then,this paper constructs a spatial weight matrix and studies the spatial autocorrelation of carbon emissions in various provinces of China by the Moran I examine.Further,this paper compares the transitions of carbon emissions in different provinces,and analyses the spatial clustering mode and spillover effect of carbon emissions in China.Finally,the spatial econometric model is established,and the effects of human capital,scientific research investment and control variables on China's carbon emissions are studied.Our primary conclusions are as follows: China's inter-provincial carbon emissions have significant spatial correlation,and shows varying degrees of clustering.Inner Mongolia etc.in the “H-H” cluster and Qinghai etc.in the “L-L” cluster,which have positive and negative spillover effects on carbon emissions in the surrounding areas.Both the improvement of human capital level and the enhancement of scientific research investment have an inhibitory effect on carbon emissions,and the inhibitory effect impact of human capital on carbon emissions is relatively strong.
