摘要
以2003—2012年281个城市的面板数据为研究样本,通过随机效应模型与分位数回归等方法检验信息化与工业废水、工业二氧化硫(SO_2)、工业烟尘等三种污染物排放强度的关系。研究发现,信息化能够有效降低工业SO_2与工业烟尘的排放强度,对工业废水排放强度的作用效果并不明显。分位数回归结果表明,当污染排放强度较低时,信息化对降低污染排放强度的作用十分明显;当污染排放强度较高时,信息化的作用不再显著。
Using panel data from 281 Chinese cites from 2003 to 2012 ,the relationship between informatization and environmental pollution intensity, which is represented by industrial waste water, industrial S02, and industrial dust is studied based on the method of random effect model and quantile regression. It is found that, the relationship between informatization and industrial waste gas, which is represented by industrial SO2 and industrial dust, is negative. However the relationship informatization and industrial waste water is not obvious. Moreover, the impact of informatization on pollution intensity is more significant when the pollution intensity is low, and not significant when the pollution intensity is high.
