石化企业内部碳定价方法研究

Research on the Internal Carbon Pricing Method for Petrochemical Enterprise

通过对企业内部碳定价常用方法的对比分析,优选影子价格法作为企业碳定价方法,并采用被广泛用来计算二氧化碳影子价格的参数化方向性距离函数,进行建模并代入相关数据求解,最终算出了3种不同规模类型石化企业的碳排放影子价格。企业可以依据其内部碳价水平制定合理的碳市场交易决策,同时将碳价应用于企业固定资产投资的经济性评价,用经济手段促进节能减排和低碳发展。

Through the comparison of several common internal carbon pricing methods,the shadow price method is selected as the carbon pricing method for petrochemical enterprise,and the parametric directional distance function(DDF)is used for trial calculation.Finally,the carbon emission shadow price of typical petrochemical enterprises with three different scales is obtained.Through the calculation and analysis of the internal carbon price of the enterprise,the enterprise can have a general understanding of its carbon marginal abatement cost.The enterprise can make reasonable decisions in the carbon market according to its internal carbon price level.At the same time,the internal carbon price is applied to the economic evaluation of the investment in fixed assets,so as to promote energy conservation,emission reduction and low-carbon development by economic means.
