针对收益不确定性而导致的绿色产品创新动力不足问题，结合现实国情，将绿色产品的发展分为创新期、推广期和普及期三个阶段，采用博弈论和最优化理论探讨了绿色产品创新和扩散过程中制造企业间的博弈行为，得到了创新企业和竞争企业在不同阶段的决策结果．基于对市场逆需求系数等参数的分析，提出了推动绿色产品创新及其扩散的前提条件和相关措施．研究表明：在一定的企业内外部条件下，绿色产品创新者具有先动优势，同行企业间的博弈竞争是推动绿色产品发展的重要动力和有效渠道，并推动消费者福利不断增加．

英文摘要：

Aimed at the lacking of green product（GP） innovation caused by the payoff uncertainty, the pro- cedures of GP＇s development among peer enterprises is discussed. Based on China＇s realities, the spread of GP is divided into three stages： the innovation stage, diffusion stage and popularization stage. Applying the game theory to discuss peer manufacturers＇ competition during the GP＇s spread, the strategic behaviors of both innovative enterprises and competitive enterprises at each stage are obtained. By the analysis of parameters such as inverse-demand coefficient and product＇s marginal cost, the prerequisites and measures to promote the GP＇s innovation and diffusion are proposed. The results manifest that under certain internal and extemal con- ditions, the innovator of GP has the first-mover advantage, and the peer manufacturers＇ competition is the main motivation and effective channel to promote GP＇s development and to enhance the customer welfare.
