Choice of Subsidy Policy Instruments for Promoting Green Technological Progress
The existing literature focuses on the impact of government subsidies on technological progress,but does not pay attention to their effects on green technological progress,especially neglecting the differential effects of various subsidy policy instruments.This paper employs the biased technological progress framework proposed by Acemoglu et al.to mathematically deduce the differential impacts and mechanisms of environmental subsidies and research and development(R&D)subsidies on green technological progress.Subsequently,the theoretical results are empirically tested by decomposing and measuring the provincial industrial green technological progress index in China from 2001 to 2020.The result shows that both environmental subsidies and R&D subsidies have a positive impact on green technological progress.Environmental subsidies mainly promote green technological progress by enhancing technology diffusion,and their effect is negatively moderated by relative energy prices.R&D subsidies promote green technological progress by incentivizing independent R&D,and their effect is positively moderated by relative energy prices.Further analysis reveals that with the deepening of China's energy market reform and the market-oriented transformation of environmental policies in recent years,relative energy prices have continued to rise,which has helped to increase the promoting effect of R&D subsidies on green technological progress.It is recommended that the central government of China coordinate the design of energy policies,environmental policies,and industrial subsidy plans to guide local governments to strengthen their efforts in environmental subsidies and R&D subsidies.Local governments in China should adjust their subsidy strategies in a timely and appropriate manner based on a precise understanding of national energy and environmental policy deployments.This will allow them to gradually shift policy resources from environmental subsidies towards R&D subsidies.
