Is There Any Difference in the Effect of Different R and D Sources on Carbon Intensity in China

摘要: In recent decades, climate change, mostly caused by CO2 emissions, has become a critical issue of concern to people worldwide. It is necessary for countries all around the world reduce carbon emissions. China, as world’s largest emitter, under great pressure implement carbon-reduction strategies. Technological progress plays crucial role in balancing environmental and economic development. The main objective this work empirically compare effects government enterprise research development (R D) on carbon-emission reduction using panel data 30 Chinese provinces from 2009 2016. both R D investment intensity are compared detail through linear model threshold-regression model. Linear-regression results shows that decrease intensity, while tends be more instant. Further indicate different urbanization stages. Guiding enterprises invest medium-developing areas, increasing support subsidies activities underdeveloped areas should an important goal policies.
