摘要

在碳限额与交易政策约束下,减排企业不仅要考虑当期的碳排放量,还需要考虑在``祖父原则"下当期决策对后期碳配额的影响,以及碳交易价格的时间动态性.文章综合考虑减排投入成本和政府碳政策,研究企业在多期生产中的减排决策和产品定价问题.结论表明: 1)在一定成本和碳政策条件下,企业会进行产品减排,最优减排率和产品价格由减排技术参数、下期碳配额比例和多期碳价共同决定; 2) 企业单期利润是当期碳价的凹函数,是下期碳价和碳配额分配比例的凸函数; 3)企业通过产品减排可以增加产品需求和增加企业利润,同时会增加产量,但是企业在进行产品减排时的多期总排放量总是低于传统企业,可降低社会总体排放水平.

Abstract

Constraint by the cap-and-trade regulation, firms would analyze their current carbon emissions and the impacts to the next period's carbon permits allocation in ``grandfathering rule" and the carbon trading price fluctuation in time. This paper considers the firm's carbon reduction costs and carbon regulations to analyze firm's carbon reduction and pricing decisions in a multi-period production problem. The findings are: 1) Firms will reduce product carbon emissions in certain costs and policy conditions. The optimal carbon reduction rate and price are decided by carbon abatement technology parameters, sequential period's carbon allocation ratio and carbon prices. 2) Firm's single period's profit is concave in current period's carbon price and convex in next period's carbon price and carbon allocation ratio. 3) The firm's product carbon reduction will increase demand and firm's profit, and the social emissions is reduced because less emissions are emitted compared to the non-carbon reduction counterparts.
