中国工业细分部门对环境污染的影响分析——基于产业网络分析的实证研究

Research on Influence of Chinese Industrial Segment Sectors on Environmental Pollution——Based on Industrial Network Analysis

为了探究网络位置如何影响工业发展与空气污染的关系,本文针对我国23个工业细分部门,采用网络分析方法,依据部门网络位置将其分为3组,继而分别采用STIRPAT模型和岭回归法分析工业部门与空气污染之间的关系。结果表明:(1)工业部门人均工业产值越高,造成的空气污染越严重。(2)网络中心的部门,增加研发经费可减少空气污染;而非网络核心的部门,结果相反。(3)与其他产业联系紧密的部门,其单位产值造成的空气污染相对更严重。

To explore how network location affects the impacts of industrial development on air pollution, this paper applies network analysis method to divide 23 industrial sectors in China into 3 groups. Then, STIRPAT model and ridge regression method are applied to calculate the relationship between industrial development and air pollution. It is proved that： （1） the higher per capita industrial output, the more serious air pollution it will cause; （2） the developed industrial sectors at centre location may decrease the air pollution if adding R＆D expenditures, while the off- centre- position industrial sectors may aggravate pollution indirectly; （3） the unit output of industrial sectors which closely link with others will trigger mare serious air pollution.
