限额交易减排政策对企业生产策略的影响

Impacts of Cap-and-trade Abatement Policy on Firms' Production Strategy

随着减排要求日益强烈,排放限制已成为排放依赖型企业生产策略制订的重要约束。基于报童模型分析框架,分别在强制减排政策和限额交易减排政策的约束下,建立了企业期望利润最大化的优化模型。根据两种政策下企业最优产量决策和最大期望收益的比较发现,尽管限额交易减排政策一方面降低了企业的产量,同时减少排放量,但并未相应地减少企业的期望收益。

With the increasingly intense requirements for emission reduction,restrictions on emissions has become an important constraint for emission-dependent-enterprises to make production decisions.Using newsboy model as an analytical framework,we develop expected net income optimization models under the constraint of command-and-control and cap-and-trade mechanism,respectively.By the comparison between optimal production decision and maximum expected net income under the two mechanisms,we find that CEA trade market can reduce the optimal amount of production and carbon emission on one hand,and it does not decrease firms＇ ENI on the another hand.
