Abstract: Under the background of green development,green transformation and upgrading have become an inevitable trend for enterprise development.Aiming at the problem of green technology innovation of enterprises and sharing of green technology among competitors in competitive environment,a competitive supply chain was constructed that composed of a supplier,a shortsighted manufacturer and a farsighted manufacturer with overconfidence tendency.The influence of different factors on green technology innovation and sharing decision of farsighted manufacturer was discussed through using game theory and revers induction method.The results showed that the green technology innovation of farsighted manufacturer could break the pattern of balanced competition between the two manufacturers,and the competitive advantage of product differentiation makes him dominant in market share and profit.The tendency of overconfidence could bring deviation to the profit of farsighted manufacturer,but the influence intensity of overconfidence was weakened with the decrease of innovation efficiency.Green cost sharing could strengthen the influence of overconfidence on market competition,and also increase the degree of profit deviation of farsighted manufacturer.However,sharing green technology in the dominant region of green technology sharing mode not only achieved mutual benefit and win-win among competitors,but also promoted the green transformation and upgrading of shortsighted manufacturer,thereby accelerating the green development process of the whole supply chain.

Key words: market competition, overconfidence, farsighted manufacturer, green technology innovation, shared cooperation

摘要： 在绿色发展的时代背景下,绿色转型升级已成为企业发展的必然趋势。本文针对竞争环境下企业绿色技术创新和竞争主体之间共享绿色技术的问题,构建一个由供应商、短视型制造商和存在过度自信倾向的远视型制造商组成的竞争型供应链,运用博弈理论和逆向归纳法,探讨不同因素对远视型制造商绿色技术创新与共享决策的影响。研究表明,绿色技术创新会打破两制造商均势竞争的格局,产品差异化的竞争优势使远视型制造商在市场份额和利润方面都处于主导地位;过度自信会给远视型制造商的利润带来偏差,但是过度自信的影响强度会随着创新效率的降低而减弱;绿色化成本分担会强化过度自信影响市场竞争的强度,也会增大远视型制造商的利润偏差的程度,但是在绿色技术共享模式占优的区域内共享绿色技术不仅达成竞争主体之间的互利共赢,还会助推短视型制造商绿色转型升级,从而加速整个供应链绿色发展的进程。
