随机需求下考虑碳限额与交易规制的企业生产策略研究

本文从企业的角度出发,建立了在碳限额政策、碳限额与交易政策、碳限额与交易政策加绿色技术投入三种情形下的生产策略模型。研究结果表明:(1)在碳限额政策下,企业的最优生产量和期望利润均不会大于在无限额下的最优生产量和期望利润。(2)在碳限额与交易政策下的最优生产量低于无限额下的最优生产量,高于碳限额下的最优生产量。此时,企业的最优生产量主要取决于限额时的产品边际利润大小,企业的期望利润主要取决于政府的初始碳配额量;(3)在碳限额与交易政策下,进行绿色技术投入后的最优生产量低于无限额下的最优生产量,此时,企业最优生产量主要取决于限额时的产品边际利润大小;(4)在碳限额与交易政策下,适当的绿色技术投入能够增加生产企业期望利润。

The Production Strategy in Considering Cap-and-Trade Regulation Under Stochastic Demand

With the cap-and-trade regulation, this paper aims to make a study of production strategy from the perspective of the manufacturer. It has constructed the optimal cap model, cap-and-trade model, cap-and-trade model considering green technology input. The following conclusion can be drawn: (1)The manufacturer’s profit and quantity with carbon emission constraint will be lower than the case without carbon emission constraint. (2)The manufacture’s maximum quantity under cap-and trade is lower than the case without carbon emission constraint, and higher than the case under cap. The manufacture’s maximum quantity under cap-and-trade depends on the marginal profit in cap and The maximum expected profit in this situation depends on the initial allowance. (3)The manufacture’s maximum quantity concerning green technology under cap-and-trade is lower than the case without carbon emission constraint. The manufacture’s maximum quantity concerning green technology under cap-and-trade depends on the marginal profit in cap. (4)Under cap-and-trade, proper green technology input will improve manufacture’s expected profit.
