不同环境规制下企业废旧产品回收的动态决策研究

制定科学可行的政策措施是促进企业废旧产品回收再利用的重要手段.在经典博弈论的基础上,充分考虑声誉对企业绩效的正向影响,并将时间因素引入分析模型中,构建了以制造商为主导的动态Stackelberg博弈模型.用该模型系统分析了无约束条件下、奖励条件下、惩罚条件下及奖惩条件下制造商废旧产品回收量、废旧产品回收率、制造商和零售量的利润、制造商的声誉、供应链系统利润,探索了每种政策措施的适用条件及绩效.研究发现,企业具有明显的趋利避害的属性,对于不同政策具有不同的适应时间;企业进行绿色技术创新能够有效地改善其经济绩效和环境绩效;惩罚和奖惩机制在提高回收率(量)和企业声誉的同时,却降低了不同主体与系统的利润;奖励机制对各类要素的作用是正向的,但是需要政府资金支持;奖惩机制的效用大小与政府规定的废旧产品回收率有关.在上述研究结论的基础上,给出了相应的政策建议,以期为绿色转型发展提供相关的理论支撑.

The dynamic analysis and simulation of different government regulations in product-recovery supply chain

Scientifically policy are important measures to promote recycling and reuse of used products. Based on classical game theory, the positive influence of reputation on firm performance was fully considered, and the time factor was also introduced into the analysis model, thus a dynamic Stackelberg game model dominated by manufacturers was constructed. The model was used to compare and analyze the amount of manufacturer's recycling of used products, recycling rate of used products, profit of manufacturers and retail sales, reputation of manufacturers, profit of supply chain system, under the unconstrained conditions, reward conditions, punishment conditions, and rewards-punishments conditions, respectively. The applicable conditions and effects of each policy measure were explored. The study finds that enterprises have obvious characteristics of seeking benefits and avoiding disadvantages, and have different adaptation time for different policies. Enterprises' green technology innovation can effectively improve their economic performance and environmental performance; punishment and reward-punishment mechanisms increase recovery rate (amount), at the same time as corporate reputation, while it may also lower the profits of different agents and systems. The role of incentive mechanisms is positive, but it requires government funds support; the effectiveness of rewards-punishments mechanism is related to the rate of recovery of used products prescribed by the government. Based on the above conclusions, the specific policy recommendations are given to provide relevant theoretical support for the coordinated development of the green transformation.
