随着环境污染加剧,我国减排形势日益严峻,但目前资源政策设计过度关注社会经济影响,较少涉及减排和环境福利,不利于生态文明建设和社会可持续发展.本文构建动态可计算一般均衡模型(dynamic computable general equilibrium,简称动态CGE模型),以煤炭资源税改革为研究对象模拟资源政策调整的长期影响,分别采用煤炭资源税率调整和资源价值补偿政策场景,探索资源政策调整对促进减排和改善环境福利的作用.研究表明:总体而言,资源政策调整有利于促进减排和环境福利,但不同政策方案设计产生的影响差异性较大;煤炭资源税率提高会在一定程度上抑制资源消费,提高资源利用效率和人均资源盈余,降低环境损失;而资源价值补偿政策实施将对我国环境质量改善产生积极作用,可以有效提高环境福利;因此,在减排和环境福利综合视角下,煤炭资源税改革必须注重资源政策方案设计的协调性和完整性,才能有效发挥资源政策对环境系统的有效引导和激励作用.
Resource tax reform will be done during China＇s 12m Five-Year Plan, but related research is still lacking. Here, we build a computable general equilibrium model （CGE） comprising the functional equations of production, consumption, income/expenditure and resources to analyze the resource tax rate. The model uses the valorem tax levy to simulate the impact of economic and resource systems with different resource tax rates, by referencing the expected rate ranges of China and developed countries. The results show that the impact is different for social, economic and resources of varying degrees. In the relatively stable period of economic development, we can select a tax rate of 5% to 7%; during higher economic development we can select an optional high level of resource tax; and in a fluctuating economy we can choose a lower tax level.
