环境规制对京津冀污染型产业空间分布的影响

Impacts of Environmental Regulation on the Spatial Distribution of Pollution Intensive Industries in Beijing-Tianjin-Hebei Region

面对资源与环境的双重约束,不断提高的环境规制强度已对区域产业发展产生重要影响。京津冀地区污染密集型产业总量得到有效控制,但产业内部结构和空间分布的集中程度各地差异显著。回归分析结果表明,污染密集型产业的空间分布受当地污染物排放控制标准、地区出口贸易额、在岗职工平均工资及产业分布滞后一期的影响显著,政府科技支出增加有利于该类产业的转型升级,而外商投资并未在京津冀地区呈现明显的国际"污染避难所"效应。

Faced with the dual constraints of resources and the environment,the increasing strength of environmental regulation has brought important impacts to regional industry development.The total amount of pollution-intensive industries in Beijing-Tianjin-Hebei region has been effectively controlled but with significant regional differences in industries＇ internal structure and the degrees of concentration of their spatial distribution.Results of regression analysis showed that the spatial distribution of pollution-intensive industries was affected significantly by local emission control standards,export trade figures,average wage of current employees,and first-order lags of industrial distribution.The transformation and upgrading of pollution-intensive industries benefited from government＇s increased expenditures on technology.However,foreign investment in the region did not show a significant international pollution heaven effect.
