摘要
基于1997-2014年省级面板数据,选取＂离受威胁地最短距离＂和＂老工业基地数目＂作为要素市场扭曲的工具变量,重点检验要素市场扭曲影响环境污染的内生性问题。结果表明,（1）经过内生性处理后,要素市场扭曲对以SO2、COD和烟尘作为环境污染指标的实证结果均显著为正,说明要素市场扭曲加剧了环境污染。（2）若未考虑内生性问题,可能低估要素市场扭曲所带来的环境污染效应。（3）分样本时段的结果表明,随着我国要素市场扭曲程度的逐渐缓解,其环境污染效应也有所下降。（4）利用半简化式回归方法实证表明,本文的工具变量满足外生性条件。
This paper chooses the shortest distance and the number of old industrial bases as the tool variables of factor market distortion（FMD）,and tests the endogenous problem of FMD. Results show that：（1） After endogenous treatment,FMD is significantly positive for SO2,COD and soot as environmental pollution indicators,indicating that FMD exacerbate environmental pollution.（2） If the endogeneity is not considered,it may underestimate the environmental pollution effect.（3） The result of the sample period shows that the environmental pollution effect has also decreased with the gradual easing of the distortion of China＇s factor market.（4） Using the semi-simplified regression method,the empirical results show that the instrumental variables meet the external conditions.
