摘要
基于预算平衡视角,运用两阶段动态最优化模型,考虑了包括碳税、配额制、绿色权证、资本补贴、电价补贴等在内的一体化风能产业政策.分析发现:在预算限制下,电价补贴和资本补贴存在抵换关系,为促进再生能源产业发展,应统筹考虑两类补贴,取消任何一种补贴,需要提高另一种补贴作为补充;在相同补贴金额下,资本补贴弹性大于电价补贴弹性,即资本补贴的效果更佳;再生能源配额与资本补贴及碳税税率呈现反向变动关系,而与电价补贴呈现正向变动关系;绿色权证交易可以促进能源配额制的实现,其价格的提高可以降低碳税税率,减轻对经济的不利冲击;再生能源发电效率提高,应当提高其发电补贴,由于预算限制,这意味着应降低资本补贴;发电效率不同的发电厂,最优资本补贴也不同,为实现最佳补贴效果,应当实现差别化补贴.研究结论对减轻财政负担、制定综合性的有效再生能源政策具有积极的指导意义.
Based on the perspective of budget balance,using two stage dynamic optimization model,this paper considers the integrated policy instruments of wind energy industry,including carbon tax,renewable portfolio standard,green certificate,capital subsidy and price subsidy etc.The analysis finds:in the budget constraints,there is a trade-off relationship between price subsidy and capital subsidy,in order to promote the development of renewable energy industry,two types of subsidies should be considered overall,cancelling anyone of subsidies that will raise another subsidy as a supplement;for the same summoney of subsidy,the elastic elasticity of capital subsidy is greater than that of price subsidy,mean ing the effect of capital subsidy be better;renewable portfolio standard with capital subsidy as well as carbon tax rate show a negative relation,and show a positive relationship with the price subsidy;green certificate can promote the realization of energy quota system,the increase of price of green certificate can reduce the carbon tax and the adverse impact on the economy;in order to improve the efficiency of power generation of renewable energy,it should increase the power subsidy under budget constraint,which means decreasing capital subsidy;in order to achieve the best effect of subsidy,precise subsidy is needed.The re search conclusions of this paper have a positive guiding significance for reducing the financial burden and formulating the comprehensive effective renewable energy policy.
