权力结构变动下双向技术溢出和碳转移对供应链碳减排水平影响研究

Research on the Impact of Two-way Technology Spillovers and Carbon Transfer on Supply Chain Carbon Reduction Level under the Change of Power Structure

摘要:

供应链权力结构变动会对核心企业减排产生影响,准确把握不同权力结构下双向技术溢出和碳转移对供应链碳减排水平的影响机理,有助于提升供应链整体减排效果。基于供应链核心企业间权力的差异,通过构建低碳制造商主导(M1S)、传统制造商主导(M2S)、双方均势(MVN)等模式下的博弈模型,研究不同模式下供应链碳减排水平和利润的变化,最后对比分析了不同模式下双向技术溢出和碳转移对供应链碳减排水平的影响。研究发现：(1)碳转移和水平技术溢出效应均降低供应链碳减排水平；垂直技术溢出效应提升供应链碳减排水平,但其提升效果取决于碳转移量的多少。(2)受权力结构变动影响,低碳制造商势力的增强能够提高供应链碳减排水平,但会对碳转移量更加敏感；传统制造商势力的增强会降低垂直技术溢出效应的减排激励作用,同时促使碳转移消极影响提前到来。(3)碳交易价格上涨会加剧碳转移对供应链碳减排水平的消极影响,其强度与权力结构及消费者低碳偏好呈现出五种变动趋势。(4)制造商是否在供应链中占据主导地位与碳减排水平直接挂钩,与其可获得的最高收益之间并无必然联系。

Abstract:

Changes in supply chain power structure will affect the emission reduction of core enterprises. Accurately grasp the impact of two-way technology spillovers and carbon transfer on the supply chain carbon reduction level under different power structure, which will help improve the overall emission reduction effect of the supply chain. Based on the power differences among the core enterprises in the supply chain, the paper, by constructing game models under the modes of low-carbon manufacturer-led (M1S), traditional manufacturer-led (M2S) and both-parity (MVN), studies the changes in the carbon emission reduction level and profits of the supply chain under different modes and analyzes the impact of two-way technology spillover and carbon transfer on the supply chain carbon reduction level of the under different modes. The study show that: (1) Carbon transfer and horizontal technology spillover effect both reduce the level of carbon reduction of the supply chain; vertical technology spillover effect increases the carbon reduction level, and its improvement effect depends on the carbon transfer volume. (2) Affected by the change of power structure, the enhancement of low-carbon manufacturer can improve the carbon emission reduction level, but will be more sensitive to the carbon transfer. The enhancement of traditional manufacturers will reduce the incentive effect of vertical technology spillover on emission reduction, and promote the negative impact of carbon transfer to come in advance. (3) Rising carbon trading price will aggravate the negative effects of carbon transfer on the supply chain carbon reduction level. And its intensity shows five different changes under the power structure and consumer low-carbon preferences. (4) Whether or not a manufacturer dominates the supply chain is directly linked to the level of carbon reduction, and there is no necessary link between it and the maximum benefits it can obtain.
