[Objective] To analyze the driving mechanism of environmental pollution

and privide support for economic derelopment and enviromental planning in Henan Province. [Methods] To interpret the dynamic changes in the environmental pollution of He'nan Province and its relationships with some driving forces based on co-integration analysis

error-correct model

impulse response function

and variance decomposition. [Results] Over all

environmental pollution had long-term co-integration relationship with GDP per capita

proportion of secondary industry

total population

foreign direct investment and government regulation

and the error correction mechanism existed. The impulse response analysis showed that GDP per capita

proportion of secondary industry and total population aggravated environmental pollution

while foreign direct investment had slightly positive impacts and government regulation has insignificant effects. According to the results of variance decomposition

total population was the most important factor for environmental pollution

followed by proportion of secondary industry and GDP per capita. [Conclusion] Rationalizing the population distribution and optimizing industrial structure is the future development orientation for environment pollution control.
