Green supply chain integration has become the key for manufacturing firms to cope with environmental challenges and gain sustainable competitiveness, but increasing the intention of firms to implement green supply chain integration is still a significant challenge. To respond to this issue, this study aims to theoretically discuss and empirically investigate the influence mechanism of institutional pressures on corporate green supply chain integration intention based on the theory of planned behavior. This study used a survey method to collect data from Chinese manufacturing firms, and the 292 finalized responses were analyzed using SPSS and AMOS. The findings indicate that institutional pressures, i.e., coercive and normative pressures, positively affect firms’ intention to implement green supply chain integration. The study also exposed the executives’ environmental awareness positively moderates the effect of coercive and normative pressures on green supply chain integration intention. Furthermore, executives’ self-efficacy positively moderates the effect of normative pressure on green supply chain integration intention. The findings of this study help deepen the understanding of the formation mechanism of green supply chain integration intention, which provides practical insights for effectively promoting green supply chain integration and realizing green transformation and high-quality development of manufacturing enterprises.绿色供应链整合（green supply chain integration）已成为制造企业应对环境挑战、获取可持续竞争力的核心路径，但提升企业实施绿色供应链整合的意愿仍是一项重大挑战。针对这一问题，本研究基于计划行为理论（theory of planned behavior），旨在从理论层面探讨并实证检验制度压力对企业绿色供应链整合意愿的影响机制。本研究采用问卷调查法从中国制造企业收集数据，最终回收的292份有效问卷通过SPSS与AMOS进行分析。研究结果显示，制度压力（即强制型压力与规范型压力）对企业实施绿色供应链整合的意愿具有显著正向影响。本研究同时发现，高管环境意识对强制型压力、规范型压力与绿色供应链整合意愿之间的关系具有正向调节作用。此外，高管自我效能感对规范型压力与绿色供应链整合意愿之间的关系同样具有正向调节作用。本研究结果有助于深化对绿色供应链整合意愿形成机制的认知，可为有效推动绿色供应链整合、实现制造企业绿色转型与高质量发展提供实践参考。
