| As our economy moves towards a comprehensive and high-quality development path of improving quality and efficiency,ecological tax and government subsidies,as important fiscal means to regulate energy consumption and pollution,have played an effective role in promoting rational allocation of resources,improving technological innovation capacity and promoting environmental protection.Therefore,how to effectively implement fiscal policies to meet the requirements of green economic development is a theoretical and practical problem that needs to be paid attention to in realizing sustainable economic and social development.Based on the above background,this paper starts with the basic concept and theoretical basis of fiscal policy and economic green development,and analyzes the impact mechanism of fiscal policy implementation on green economic development.Secondly,the data of 30 provinces in China from 2007 to 2020 are taken as samples to calculate and analyze GTFP and its decomposition index.Then construct models to empirically test the impact of fiscal policy implementation on green economic development.Through theoretical and empirical analysis,this paper draws the following conclusions:(1)GML at the national level fluctuates greatly only around 2008,and then gradually converges to the frontier,with no upward or downward trend on the whole.At the regional level,technological progress and efficiency in both eastern and central regions have achieved growth,while green technological efficiency is the main engine in the western region.(2)The implementation of ecological tax policy has a positive effect on green economic development,while the implementation of government subsidy policy has a negative effect on green economic development;When ecological tax is used as the threshold variable,the interaction term of ecological tax and government subsidy has three effects on economic green development,and the policy implementation effect is the best when the intensity of ecological tax is between 0.2224 and 0.2444.Based on the above conclusions,this paper puts forward a reasonable grasp of the use of fiscal policy tools and intensity,and pay attention to the government subsidies on the alleviation of corporate financing constraints;Speeding up technological innovation in the ecological field to provide new wisdom for "ecological China" and better achieve balanced economic and environmental development. |
