以外商直接投资和三废排放治理支出作为研究变量,运用时间序列分析的格兰杰因果检验和DF/ADF平稳性检验方法,实证分析我国外商直接投资与环境规制之间的因果关系和长期变动关系的结果显示:外商直接投资与环境规制之间具有一定的因果关系,外商直接投资是环境规制的原因,在滞后一期和二期时环境规制对外商直接投资的流入没有影响,但在滞后三期时对外商直接投资具有一定的影响;我国的外商直接投资活动与环境规制行为在长期内不存在相近的走势。国家有关部门在制定相关投资与环境政策时不应忽视这些特点。
Taking FDI and discharged investment on controlling waste gas, wastewater and industrial residue as research variables, and using methods of Granger causal test of time series analysis and DF/ADF stationariness test, this paper makes a positive study on causal and fluctuant relations between foreign direct investment and environmental regulations. An analytical result shows that there is a certain causal relation between them. The foreign direct investment is a cause of environmental regulations. The environmental regulations in their first and second lag periods do not influence inflows of FDI; however, in their third lag period there are some influences on the FDI inflow. In a long term there is no similar trend to the FDI movement and the environmental regulation action. Their relations and dynamic trends should not be ignored when the government works out policies for investment and environment.
