The growth of China's OFDI (outward foreign direct investment) is a unique feature of the "Belt and Road" project. Does China's OFDI have a green halo effect on countries along the Belt and Road (B&R)? Is this green halo effect somehow asymmetrical? What is the underlying mechanism? This paper systematically examines how China's OFDI exerts its influence on green technology spillovers, based on 56 B&R countries' 2003-2019 panel data. This study makes three significant findings: Firstly, China's OFDI has positive asymmetric characteristics in promoting green technology spillovers to host countries mentioned, which have lower income levels and openness. Secondly, strict relative environmental regulation can act as a "pressure pool," significantly enhancing the "green halo effect"; Thirdly, China's OFDI can help host countries obtain more green technology spillovers through three channels: expanding host countries' economic scale, upgrading host countries' industrial structure, and suppressing host countries' use of non-renewable energy. These findings point the way for 56 host countries to better accessing green technology spillovers.
中国对外直接投资（OFDI）的增长是“一带一路”项目的一个独特特征。中国的 OFDI 是否对“一带一路”沿线国家（B&R）具有绿色光环效应？这种绿色光环效应是否存在某种不对称性？其潜在机制是什么？本文基于 56 个“一带一路”国家 2003-2019 年的面板数据，系统考察了中国 OFDI 如何对绿色技术溢出产生影响。本研究得出了三个重要结论：首先，中国的 OFDI 在促进绿色技术溢出方面具有积极的非对称特征，对收入水平和开放程度较低的东道国更为明显。其次，严格的相对环境规制可以充当“压力池”，显著增强“绿色光环效应”。第三，中国的 OFDI 可以通过三种渠道帮助东道国获得更多的绿色技术溢出：扩大东道国的经济规模、升级东道国的产业结构以及抑制东道国对不可再生能源的使用。这些发现为 56 个东道国更好地获取绿色技术溢出指明了方向。
