在“双碳”战略目标下，数字化绿色化协同转型已成为驱动经济高质量发展的关键路径。本文立足宏观政策协同视角，聚焦中观供应链层面，将“供应链创新与应用试点”与“绿色供应链管理试点”的双重政策组合视为一项准自然实验，基于中国2008—2023年上市企业数据，运用双重差分模型探究供应链双化协同对企业绿色创新的影响及其供应链传导机制。研究发现，供应链数字化绿色化政策协同显著促进了企业绿色创新。机制分析表明，供应链数字化政策与绿色化政策对企业绿色创新不仅具有明显的协同共促效应，也能够通过强化供应链韧性、提高供应链透明度以及促进供应链金融发展间接提升企业绿色创新水平。异质性研究发现，对于国有企业、高研发投入企业和高竞争行业，供应链数字化绿色化政策协同对企业绿色创新的赋能效果更为显著。进一步研究表明，供应链数字化绿色化政策协同对企业绿色创新的促进作用要强于单一政策。在供应链纵向关系中，供应链数字化绿色化政策协同对企业绿色创新的影响存在非对称性，能够显著促进上游企业绿色创新，但对下游企业的驱动效应尚未显现。本文为政府优化政策设计、统筹发挥“数字—绿色”供应链政策的协同效能提供了学理依据，也为微观企业主体践行绿色创新实践提供了经验证据与政策启示。

Under the “dual carbon” strategic goal, digital and green collaborative transformation has become a key path to drive high-quality economic development. This paper is based on the macro policy coordination perspective, focusing on the meso-level supply chain. The dual policy combination of “supply chain innovation and application pilot” and “green supply chain management pilot” is regarded as a quasi-natural experiment. Based on the data of Chinese listed companies from 2008 to 2023, the difference-in-differences model is used to examine the impact of supply chain dual synergy on corporate green innovation and its supply chain transmission mechanism. It is found that, the synergy of digital and green policies in the supply chain significantly promotes the improvement of green innovation in enterprises. Mechanism analysis shows that supply chain digitalization policies and green policies not only have a significant synergistic effect on corporate green innovation, but also indirectly enhance the level of corporate green innovation by strengthening supply chain resilience, improving supply chain transparency, and promoting the development of supply chain finance. Heterogeneity analysis shows that for state-owned enterprises, high R&D investment enterprises, and highly competitive industries, the synergistic effect of supply chain digitalization and green policies on empowering green innovation in enterprises is more significant. Further research shows that the synergistic effect of supply chain digitalization and green policies on promoting green innovation in enterprises is stronger than that of a single policy. In the vertical relationship of the supply chain, there is asymmetry in the impact of digital and green policy coordination on enterprise green innovation, which can significantly promote upstream enterprise green innovation, but the driving effect on downstream enterprises has not yet been manifested. This paper provides a theoretical basis for the government to optimize policy design and coordinate the synergistic effects of “digital green” supply chain policies, and also provides empirical evidence and policy insights for micro enterprise entities to practice green innovation practices.
