随机需求下考虑排污权交易的制造商最优生产与定价联合决策研究

Research on Manufacturer′s Optimal Production and Pricing Strategies Considering Emission Trade and Stochastic Demand

在考虑排污权交易的情况下,研究了具有价格依赖需求特征的排污制造商如何进行单周期生产和定价联合决策的问题。研究表明:制造商的最优生产量和最优定价存在且唯一;制造商的最大期望利润既是排污权交易一级市场排污权交易价格的减函数,也是二级市场排污权交易价格的减函数(当最优生产量大于排污上限时)或增函数(当最优生产量小于排污上限时);与不考虑排污权交易的情况相比,排污权交易二级市场的存在可以促进制造商进行减排投资、提高排污生产效率;由制造商决策对排污权交易政策的反应函数可知,排污权交易中的各种政策因素和市场因素都会对制造商的生产经营决策产生显著影响。

Considering emission trading, this paper studies the optimal production and pricing strategies of the manufacturer who faces random price-dependent demand. The results show as follows：the optimal production quantity and the optimal price of the manufacturer all exist and are unique;the maximum expected profit is the decreasing function of emission trading price in the primary market, and is also the decreasing function of emission trading price in the secondary market（when the optimal production quantity is more than the upper limit of emission） or the increasing function of emission trading price in the secondary market（when the optimal production quantity is less than the upper limit of emission） ;the existence of the secondary market of emission trading could promote the emission manufacturer to invest in emission and increase the emission efficiency;according to the emission trading reaction function,different policy and market factors significantly impact enterprise＇s production decisions.
