【摘要】：文章建立了一个包含环境外部性和减排研发的内生经济增长模型,通过动态模型求解和数值模拟分析,研究了减排研发补贴政策、环境税收政策对环境、经济增长率及社会福利水平的影响,并进一步讨论了政府可选择的最优政策工具组合。结论表明:当经济体中存在双重外部性时,组合政策情形下的研发水平、环境、经济增长率和社会福利水平高于单一政策;随着研发补贴率增大,经济增长率、社会福利水平不断增大,污染排放呈先上升后下降的趋势;污染税政策的经济和环境效果优于能源税政策;政府通过征收污染税对企业的减排研发活动进行适当补贴能够取得环境、经济增长率和社会福利水平的“三赢”。
[Abstract]:This paper establishes an endogenous economic growth model which includes environmental externalities and emission reduction research and development. Through dynamic model solution and numerical simulation analysis, the paper studies the subsidy policy of R & D emission reduction, environmental tax policy on the environment. The influence of economic growth rate and social welfare level, and further discuss the optimal policy tool combination that the government can choose. The conclusion shows that when there is dual externality in the economy, the R & D level and environment in the case of portfolio policy are discussed. The economic growth rate and the social welfare level are higher than the single policy, with the increase of R & D subsidy rate, the economic growth rate, the social welfare level is increasing, and the pollution emission is rising first and then decreasing. The economic and environmental effects of the pollution tax policy are better than those of the energy tax policy, and the government can obtain the "triple win" of the environment, economic growth rate and social welfare level by levying the pollution tax to subsidize the enterprise's R & D activities.
