3286作为一种逐步兴起的新型政策手段，自愿性环境规制能否更好地平衡环境保护和经济增长，是值得深入研究的重要问题。文章利用中国工业企业数据、工业企业污染排放数据和政府节能采购企业清单，通过构建双重差分模型，实证检验了政府节能采购政策对企业污染排放的影响。研究发现，政府节能采购政策实施后，实验组的二氧化硫排放量相对于对照组显著降低，说明政府节能采购政策抑制了企业污染排放。经过多种稳健性检验，这一结论依然成立。机制检验表明，政府节能采购政策通过严格约束生产的各个环节，抑制了企业污染排放，具体包括在生产初始阶段改善能源结构、在生产过程中创新生产技术以及在生产终端提高污染处理能力。异质性检验表明，由于打破了原有的政企合谋氛围，政府节能采购政策使国有企业的污染减排效果更明显；此外，这一政策还赋予了企业更多的自主权，使得低污染排放强度企业的污染减排效果更明显。同时，在减少企业污染排放的同时，政府节能采购政策还提高了企业产量和绿色全要素生产率。文章研究表明，自愿性环境规制能够较好地平衡环境保护和经济增长，为经济高质量发展阶段政府制定有效的环境政策提供了有益的启示。
