Will the Environmental Taxation Promote Enterprise Upgrading?——Based on the Mesomeric Effect of Innovation Investment

本文以2013~2018年我国沪深A股重污染上市企业数据为研究样本,检验了环保税对企业升级的影响以及创新投入在二者之间的中介效应。研究表明,环保税通过提高企业创新投入促进企业升级,并且这种关系主要存在于民营企业样本中。进一步检验表明,相对于中西部地区,东部地区环保税对企业升级的促进作用更为显著。对此,本文提出改进环保税激励机制,依据企业差异调整环保税税率,适时调整地区间环保税政策等建议。
