摘要: 从同群效应出发,探讨政府通过绿色采购对同业绿色创新的溢出效应。研究表明,政府绿色采购对企业绿色创新存在明显的行业内溢出效应,显著提高了本地同行业未获采购企业的绿色创新水平。这种绿色创新溢出效应主要通过推动同群企业间的市场竞争以及知识溢出,进而提高了未获采购企业的绿色创新水平。政府绿色采购对未获采购企业绿色创新的溢出效应在不同的内部与外部约束环境下呈现出明显的异质性:当企业高管环保意识越强、获得的分析师关注度越高以及企业合作文化越好时,政府绿色采购对未获采购企业的绿色创新溢出效应越明显。进一步分析表明,政府绿色采购的溢出效应提高了未获采购企业环境社会责任,改善了其环境绩效。应有效发挥政府绿色采购示范作用、优化市场竞争环境,通过构建地方政府与机构投资者等多方协同机制放大政策溢出效应。

Abstract: Starting from the peer effect, this paper explores the spillover effect of public green procurement on the green innovation in the same industry. The research has found that public green procurement has a significant industry spillover effect on corporate green innovation, that is, public green procurement can significantly improve the level of green innovation among local enterprises in the same industry that have not received procurement. This green innovation spillover effect mainly improves the green innovation in non-purchasing firms by increasing the market competition and promoting knowledge spillover among peer enterprises. The spillover effect of public green procurement on green innovation in non-purchasing enterprises shows obvious heterogeneity under different internal and external constraints: when the environmental awareness of corporate executives is stronger, the attention of analysts is higher, and when the culture of corporate cooperation is better, the spillover effect of public green procurement on green innovation of non-purchasing enterprises is more obvious. Further analyse reveals that the spillover effect of public green procurement has increased the environmental social responsibility of non-purchasing enterprises, thereby improving their environmental performance. It is necessary for the government to effectively leverage its exemplary role in green procurement, optimize the competitive market environment, and amplify policy spillover effects by establishing a multi-stakeholder coordination mechanism involving local governments and institutional investors.

Key words: government green procurement, green innovation in the same industry, spillover effect
