全球价值链不仅涉及生产和销售领域的合作,还由此衍生出基于全球范围内的污染再分配.以我国多个数据库为基础构建动态面板GMM模型,发现我国企业的全球价值链参与程度与污染排放呈现出非线性的倒U型关系,即企业污染排放随着全球价值链参与程度的上升先增加后降低.同时,上游度和下游度与污染排放影响的模型显示,上游度与污染排放负相关,企业在全球价值链当中的上游环节经济成分会产生减排效果;下游度与污染排放是正相关关系,表示企业在全球价值链当中的上游环节经济成分会增加污染排放.而多重中介效应模型说明,这种非线性倒U型关系的形成是企业上游参与度和下游参与度共同影响下的最终结果.
This article constructs a dynamic panel GMM model and finds that the degree of GVC participation of enterprises and pollution emissions show a nonlinear inverted U-shaped relationship.The pollution emission of enterprises increases and then decreases with the increase of GVC participation degree.This article further constructs upstream degree and downstream degree and pollution emission impact model and finds that upstream degree is negatively correlated with pollution emission,the upstream economic component of enterprises in GVC will produce emission reduction effect;while the downstream degree is positively correlated with pollution emission,which means that the upstream economic component of enterprises in GVC will increase the pollution emission.Based on the above conclusions,this article constructs a multiple mediation effect model and finds that the formation of the inverted U-shaped relationship is the final result of the mutual influence of the upstream and downstream participation of enterprises.
